Radiotelemetry transmitters were surgically implanted in 28 female ICR mice. A mock ova implantation surgery was then performed. Mice were treated with a single dose of buprenorphine or flunixin meglumine prior to or after surgery, three doses of buprenorphine, or were untreated. Heart rate, blood pressure, home cage activity, food and water consumption, and body weight were measured. The no-analgesia group showed no significant differences between any parameters collected prior to surgery and those collected at similar times during the day of surgery. Significant increases in mouse activity on the day of surgery occurred with all analgesic treatments, compared with pre-surgical activity. There were no consistent significant changes in any other telemetry parameter after treatment with analgesics compared with no analgesia. Food consumption and body weight the day after surgery were reduced significantly in the animals treated with three doses of buprenorphine compared with untreated mice and mice given a single dose of buprenorphine. We conclude that the mock ova implant procedure does not induce sufficient pain to cause alterations in heart rate and blood pressure in the mouse. Activity was significantly reduced in the first 6 h after surgery in mice without analgesia, compared with activity prior to surgery. There were no significant differences between pre-emptive and postoperative analgesia. Body weight and food and water consumption were poor measures of pain because analgesia alone affected these parameters.", pages = "37-44", url = "http://www.ingentaconnect.com/content/aalas/cm/2005/00000055/00000001/art00006" } | ESSENTIALAI-STEM |

68 HEALTHY ANATOMY.
rectum and vagina had a common opening ; this last being still alive when the above case was observed, and defeca- tion being perfectly natural. 1850.
Dr. Waldo J. Burnett.
678. Imperforate rectum. The pelvic organs were dissected by Dr. R. M. Hodges, and have been preserved in spirit ; showing the rectum, distended, and ending in a cul-de-sac, low in the pelvis, and below this a very small portion of intestine with the anus.
The child died on the sixth day, crying incessantly the last ten or twelve hours, and with the abdomen very tense and swollen ; but there was no vomiting. The urine was very scanty ; and two days before death it was slightly tinged by meconium, though nothing was found, on dis- section, to explain this fact. Case in the practice of Dr. A., and no operation performed ; a female child.
Three years previously the mother bore another male . child that lived eight days, and in which the meconium passed freely through the penis ; a perfect female having been born meanwhile. 1858. Dr. James Ayer.
679. Imperforate rectum ; intestine distended and dried.
Case in Dr. M.'s practice ; a female. Trocar passed in about two inches on the third day, but without opening the intestine, and it died on the fifth. Symptoms not urgent. The lower portion of the intestine was about an inch in extent, and the distance that separated the two portions was about the same. 1847. Dr. E. B. Moore.
680. A third specimen ; in spirit. On the fourth day a trocar was thrust in, and meconium was freely discharged. The
next morning a piece of gum-elastic catheter was passed up upon a probe ; in the evening, as nothing had passed, the opening was enlarged with the knife, and a small quan- tity of meconium escaped. Death on the following day. On dissection, it was found that the probe and catheter had passed into the .cellular tissue by the side of the in- testine, and that there was an opening into the peritoneal cavity. 1869.

Rh of his classical attainments, that at a later period, to use his own expression, "he passed muster pretty well when introduced to Dr Parr."
Leyden was now at the fountain-head of knowledge, and availed himself of former privations by quaffing it in large draughts. He not only attended all the lectures usually connected with the study of theology, but several others, particularly some of the medical classes,—a circumstance which afterwards proved important to his outset in life, although at the time it could only be ascribed to his restless and impatient pursuit after science of every description. Admission to these lectures was easy from the liberality of the professors, who throw their classes gratuitously open to young men educated for the church, a privilege of which Leyden availed himself to the utmost extent. There were indeed few branches of study in which he did not make some progress. Besides the learned languages, he acquired French, Spanish, Italian, and German, was familiar with the ancient Icelandic, and studied Hebrew, Arabic, and Persian.
But though he soon became particularly distinguished by his talents as a linguist, few departments of science altogether escaped his notice. He investigated moral philosophy with the ardour common to all youths of talent who studied ethics under the auspices of professor Dugald Stewart, with whose personal notice he was honoured. He became a respectable mathematician, and was at least superficially acquainted with natural philosophy, natural history, chemistry, botany, and mineralogy. These various sciences he acquired in different degrees, and at different times, during his residence at college. They were the fruit of no very regular plan of study: whatever subject interested his mind at the time attracted his principal attention till time and industry had overcome the difficulties which it presented, and was then exchanged for another pursuit. It seemed frequently to be Leyden's object to learn just so much of a particular science as should enable him to resume it at any future period; and to those who objected to the miscellaneous, or occasionally the superficial nature of his studies, he used to answer with his favourite interjection, "Dash it, man, never mind: if you have the scaffolding ready, you can run up the masonry when you please." But this mode of study, however successful with John Leyden, cannot be safely recommended to a student of less retentive memory and robust application. With him, however, at least while he remained in Britain, it seemed a matter of little consequence for what length of time he resigned any particular branch of study; for when either some motive or mere caprice induced him to resume it, he could with little difficulty re-unite all the broken associations, and begin where he left off months or years before, without having lost an inch of ground during the interval.
The vacations which our student spent at home were employed in arranging, methodizing, and enlarging the information which he had acquired during his winter's attendance at college. His father's cottage affording him little opportunity for quiet and seclusion, he was obliged to look out for accommodations abroad, and some of his places of retreat were sufficiently extraordinary. In a wild recess, in the dean or glen which gives name to the village of Denholm, he contrived a sort of furnace for the purpose of such chemical experiments as it was adequate to performing. But his chief place of retirement was the small parish church, a gloomy and ancient building, generally believed in the neighbourhood to be haunted. To this chosen place of study, usually locked during week-days, Leyden made entrance by means of a window, read there for many hours in the day, and deposited his books and specimens in a retired pew. It was a well chosen spot of seclusion, for the kirk, (excepting during divine service) is rather a place of terror to the Scottish rustic, and that of Cavers was rendered more so by many a tale of ghosts and witchcraft, | WIKI |
A type of self-propelled vehicle, called motor vehicles, that can act on its own without pushing or hanging through the apparatus that mediates the conversion of any kind of energy it receives into a mechanical energy form is called a motor vehicle. While presenting information about motor vehicles, the answer to the question of which ones fall into this criterion brings results.
What is it? What is not?
The need for vehicles is a natural structure that has been going on since the first human. A person develops a vehicle both to carry himself and to carry loads. For this purpose, many vehicles and work machines are made. Vehicles that could not go on their own at first and were used in need of a push, break new ground with the development of the engine, which is a mechanism that ensures their self-movement over time. From cars used as automobiles to buses used for public transportation, from trucks and trains on land in freight transportation, to ships at sea, and airplanes and helicopters in the air.
Adventure from Past to Present
Traveling the distances, which is the most important link of life, and its tools are as important today as it was in the past. Even if only the last half is looked at, the situation is very different. It is obvious what condition motor vehicles were in in the past in terms of quality and level, but what they have become today. This process is sufficient to provide us with information about motor vehicles. The extent of the transportation provided by animals is seen very clearly now. All this is due to the fact that it moves rapidly with the discovery of that round object called the wheel. When the wheel was found, the engine was already certain to be found. It was obvious that that would be the next step, and it did.
Air-to-Land Water Devices
It has now become easier to cover a lot of work and distance in a short time. By laying the iron on the ground, they made a device that could move on it, which could carry both cargo and passengers, and which they called a train. After a while, the coal-fired worker was replaced by a steamer. Today, rapid and underground have been developed. The difference on the sea or on the water is the same. Boats and ships, which are sailboats and can move with the help of wind or oars, have been replaced by vehicles that can both go faster and go by themselves.
The situation in the air is much more extensive and different. While it first took place in the form of gliding from a hill with attempts to fly, first take-off took place with the use of the propeller. Then, it was further advanced, and many variants were discovered that could travel fast, carry cargo and passengers, and were used as a military deterrent weapon. All developments provide information about motor vehicles and shed light on the point reached. With the motor factor, they have become a state that is called motor vehicles and is constantly developed by carrying both fast and load. | FINEWEB-EDU |
Yankees' Tanaka has small elbow ligament tear| Reuters
New York Yankees' starting pitcher Masahiro Tanaka has been diagnosed with a partially torn ligament in his right elbow and could be out of the game for about six weeks, Yankees general manager Brian Cashman said on Thursday. Tanaka visited three doctors with each confirming a small ligament tear in his ulnar collateral ligament, but the right-hander has opted for non-surgical rehab hoping to avoid Tommy John surgery, which could mean a year out of the game. The 25-year-old Japanese pitcher, who was named for next week's All-Star game, leads the American League with 12 wins and has a 2.51 ERA, the fourth best in the AL. (Reporting by Ben Everill in Los Angeles; Editing by Greg Stutchbury) USA Hockey said on Wednesday it had put preparations for the upcoming world championships on hold amid a wage dispute with the U.S. women's team who have threatened to boycott the event. KINGSTON Reigning Commonwealth Games 400 meters hurdles champion Kaliese Spencer denied on Wednesday that she refused or evaded a drug test and plans to legally challenge the assertion by the Jamaica Anti-Doping Commission.

Preface:
Levelling and surveying methods are also used for measurements of any type of field survey work. Sometime, less accurate methods can also be used for this survey work than for water-level recording stations, although the techniques are almost common.
Definition of different Levelling
• Differential levelling is termed as to such method of measuring directly with a graduated level staff the vertical difference in elevation between two or many points.
• Precise levelling is a basically authenticate method of differential levelling which actually uses highly accurate levelling machine and with a excessive rigorous observing protocol than general type of engineering levelling process. The target is to achieve high orders of accurate measurement such as 1 mm per 10000 mm.
• Level surface is a surface which is anywhere tangential perpendicular to the direction of the gravitational force. The example of the level surface is a completely steady still lake.
• Datum level is an assumed level surface upon which elevations are referred. The very most common surveying datum is mean sea-level (MSL), at any location of earth but in hydrological work it is basically just concerned with levels in a local surrounding work area, most of the time we use:
a) An assumed datum level , which is established by providing a benchmark of an assumed value ( 100.00 m) to which all levels in the local area will be reduced by measurment.
• Reduced level is defined as the vertical distance between any survey point and the adopted level datum. | ESSENTIALAI-STEM |
Botulinum Toxin (Botox®)
So you don’t just feel younger, you also look it.
Our facial muscles enable us to express emotions: we frown to express annoyance, we contract our eyebrows to show confusion, while laughter creates wrinkles around the eyes. In youthful skin, wrinkles smooth out as soon as the muscles relax again.
However, in the process of the skin aging, fine wrinkles become more and more pronounced. This is caused by the breakdown of collagen fibres, reduced fat production and a decreasing ability of the cells to store moisture, meaning the skin increasingly loses elasticity and resilience. Botulinum toxin relaxes and smoothes the muscles and effectively slows down the visible ageing signs of the skin.
Your questions. Our answers.
What is Botox® and how does it work?
Botox® is the abbreviation for botulinum toxin type A, a protein produced by the bacterium Clostridium botulinum. It has been successfully used in a very diluted form in aesthetic medicine for about 20 years, among other things for wrinkle correction. The injection of very small amounts into the target muscle inhibits the release of acetylcholine, the messenger substance responsible for muscle contraction.
How does it affect facial expressions?
If only very small amounts are injected, the muscles can continue to work. However, they contract less intensively and the reduced facial expression allows facial wrinkles to smooth out more quickly.
Does Botox® treatment give you a mask-like face?
Not if botulinum toxin is used correctly. As the treatment not only prevents the deepening of existing wrinkles but also prevents the formation of new ones, it is worth starting treatment early.
How does the treatment work?
After an analysis of the facial expressions and the wrinkles that are perceived as troubling, we inject the smallest amounts of botulinum toxin powder dissolved in a buffer solution into the target muscle with a very fine needle. The dosage depends on the contraction strength of the muscle and the depth of the wrinkles; it is carried out in internationally-scaled units, which allows for comparability of the injected amounts. The treatment price also depends on the number of units. In the first days after the treatment the effect is not initially visible. The maximum effect is visible after about two weeks.
What is important before and after the treatment?
Before the treatment, aspirin or other anticoagulant drugs should be avoided to reduce the risk of bruising. For optimal effect, sport should be avoided for at least two days after the treatment. The use of saunas should also be avoided as heat destroys the active ingredient.
How long does the effect last?
Usually between three and six months. The injections can then be repeated for as long as the effect is desired.
Can there be complications?
Since the active ingredient is applied with a fine needle, a slight redness and swelling may temporarily occur at the injection site. In rare cases, spot bleeding (haematomas) may occur. This disappears within a few days and can be covered with make-up immediately after the treatment. The botulinum toxin is only effective at the injection site. There is therefore no risk of systemic side effects or general paralysis of the muscles. If the face shows irregularities after the treatment, these can easily be corrected by small after-treatments.
Once I have had Botox® injected, do I have to do it over and over again and does Botox® accelerate the aging process?
No, treatment with Botox® can be interrupted at any time. It can be compared to pressing the pause button to stop the aging process. The skin aging process is not accelerated and if you are happy with the results, you can continue the treatment for as long as you like.
Which areas are Botox® injections suitable for?
For frown lines, for between the eyebrows, for the transverse forehead wrinkles, for crow’s feet around the eyes, for fine wrinkles around the mouth and nose areas or the so-called strawberry wrinkles on the chin. Botulinum toxin is also used in many other areas, for example, it can also help significantly in the case of excessive sweating (hyperhidrosis). All other areas of application are shown in the following diagram.

New catalysts for the dehydrogenation of methanol to water-free formaldehyde
Some Na compds. are selective catalysts for dehydrogenation of MeOH to HCHO, stable under high temps., and not reduced by H which is formed. They undergo some deactivation due to coking, but burning the coke easily returns the catalyst to its initial activity. Catalyst performance can be improved by addn. of In, leading to selectivities ?70% and .apprx.50% yield of HCHO. [on SciFinder (R)]

Table of all ADB & Fastboot Commands for Android (Windows / Mac / Linux)
0
Share
In this article, you will find a list of all ADB and Fastboot commands for Android devices. You can execute these commands on any computer regardless of its operating system (Windows, Mac, or Linux). Commands are universal, which means that the same commands will work on any Android device, regardless of manufacturer or device type.
Android enthusiasts who are familiar with unlocking, rooting, or installing a custom recovery on their devices should be familiar with ADB and Fastboot. These are system utilities that provide the backend of Android when connected to a computer.
ADB or Android Debug Bridge can be used when an Android phone is connected to a PC in fast boot or bootloader mode. There are certain codes that can be executed using a computer to perform a function on Android devices. Most people use Fastboot to unlock the phone’s bootloader. Occasionally, you may need to unlock the device (in the case of hard bricks) using Fastboot.
Most fastboot and ADB commands return the same results on any device, regardless of manufacturer or variant. If you are stuck somewhere, where you need fastboot / adb command for help, then this post is for you. I’ve listed all the important fastboot, and ADB commands in the table below. The codes, along with their features and functions, are also properly mentioned. Use Ctrl + F to find out what you need.
Pre-requisite
Before going to the fastboot & ADB commands, you need certain tools and settings to be enabled on your device as well as the computer. Otherwise, you can not make use of the fastboot or ADB commands. The tools are needed to be installed on the computer. On the other hand, the necessary settings are to be made on the phone.
Methods are the same for all Android smartphones. So, don’t worry about the OEM or variant. Consider the following checkpoints:
1. You need to enable USB Debugging mode to connect your Android phone to computer. (Settings > About Phone > Build number > Tap it 7 times to become developer; Settings > Developer Options > USB Debugging).
2. Download Android SDK Platform Tools (ADB & Fastboot)
3. Mac users: Setup ADB on Mac (using Homebrew)
4. USB Cable: Preferably, the one provided by the manufacturer.
5. Optional: Download & Install Android USB Driver on your computer.
ADB Commands list
Here is the complete list of all the ADB commands that you can execute using the command prompt or terminal while connecting the Android device to the PC with all required settings. Perform the following if you had fulfilled the prerequisites mentioned above:
ADB devices
Push and Pull files using ADB
Push and pulls are used to transfer any files from the device to the computer or vice versa. To pull a file from the Android device to the computer, you need to provide the full path of the file. You can use the following ADB command:
adb pull </path/filename>
You need to change the file name with an extension. For example, we are pulling a file called “CartoonHD.apk“. You need to execute the command in the following way:
adb pull /system/app/CartoonHD.apk
On the other hand, while pushing files from computer to Android using ADB, you can execute the following command:
adb push <source-path> <target-path>
Same as before, you need to provide the full path with extension and the destination path as well. Check out the example below:
adb push /local/path/CartoonHD.apk /sdcard/apps/
ADB Shell Commands list
Here is the complete list of all the ADB Shell commands that you can execute using the command prompt or terminal while connecting the Android device to the PC with all required settings.
ADB Shell CommandsFunctions
adb shellStarts the remote shell command console in the device and lets you control the Android through it
adb shell wm densityUse it to change the pixel density of your Android device (details given below)
adb shell pm list packagesShows all the installed apps package name on your Android
adb shell pm list packages -sShows the list of all the system apps installed on your Android with the package name
adb shell pm list packages -3List of all the 3rd party apps installed on your Android
adb shell pm list packages -dDisabled apps list on your Android
adb shell pm list packages -eEnabled (active) apps list on your Android with package names
adb shell pm list packages -uList of all the apps that you uninstalled from your Android with installed pages
adb shell
Hit enter and execute the following:
cd /system
These commands change the directory to /system
adb shell
Hit enter and execute the following:
rm -f /sdcard/whatsapp.apk
Delete a file: replace whatsapp.apk to your desired file name with extension
adb shell
Hit enter and execute the following:
rm -d /sdcard/DCIM
Delate a folder: replace DCIM to your desired folder name
adb shell
Hit enter and execute the following:
mkdir /sdcard/Folder1
Create a new folder “Folder1” under /sdcard
adb shell
Hit enter and execute the following:
netstat
Check the network statics on your Android device using ADB
adb shell
Hit enter and execute the following:
ip -f inet addr show wlan0
Shows the device’s Wi-Fi IP address
adb shell
Hit enter and execute the following:
top
Use this Coe to monitor the running CPU process on your Android device
adb shell
Hit enter and execute the following:
getprop ro.build.version.sdk
Get the property of Android’s build.prop configuration
adb shell
Hit enter and execute the following:
setprop net.dns1 1.2.3.4
Use to set the values of built.prop configuration and change the properties
Uninstall a system app using ADB
If you want to uninstall a system app via ADB Shell command, you can execute the following code:
adb shell pm uninstall -k –user 0 package.name.com
Replace package.name.com with the actual package name that you want to uninstall from your Android system. This method is the easiest way to uninstall bloatware which comes inbuilt with the system that can not be uninstalled generally from the app menu. For example, if Facebook comes as a system app, and you want to remove it, execute the code in the following way:
pm uninstall -k --user 0 com.facebook.katana
ADB Shell dumpsys command
adb shell dumpsys
Using the dumpsys command, you can gather all the system data about your device’s hardware and software configuration. You can also use it to get information about your Android device’s specific elements, such as the battery, display, and battery stats.
adb shell dumpsys display
adb shell dumpsys battery
adb shell dumpsys batterystats
Changing the Pixel density using ADB Shell
You can easily change the Pixel density of your Android device’s screen using adb shell wm density commands. In order to do that, you need to know the actual Pixel density of your device. Let’s take an example with the Galaxy S9 Plus. At first, you need to know the original resolution executing the adb shell dumpsys command.
Following are the info about phone’s display, resolution, and density for Galaxy S9 Plus (after executing adb shell wm density):
mDisplayInfos=
PhysicalDisplayInfo{1440 x 2960, 60.000004 fps, density 3.5, 530.086 x 529.464 dpi
If you want to set a lower resolution, you can check out the following examples (remember, the values may vary from device to device):
for 1080p (FHD)
adb shell wm size 1080x2220
adb shell wm density 480
for 720p (HD)
adb shell wm size 720x1560
adb shell wm density 350
Depending on your device, you can set the values, whichever looks excellent for you.
ADB Shell command to Send SMS screen
With this ADB command, you can send a text message from your Android phone while connected to the computer:
adb shell am start -a android.intent.action.SENDTO -d sms:CCXXXXXXXXXX --es sms_body "SMS BODY GOES HERE" --ez exit_on_sent true
adb shell input keyevent 22
adb shell input keyevent 66
ADB Shell for screenshots
Using this code, you can capture a screenshot on your Android phone and pull the snapped screen to your computer instantly:
adb shell screencap /sdcard/screenshot.png
Hit enter, and then:
adb pull /sdcard/screenshot.png
Screen recording on Android using ADB Shell command
Android 4.4 Kitkat and above have a shell utility to record the screen and pull the video to the computer. Execute the following commands:
adb shell screenrecord /sdcard/movie.mp4
(Press Ctrl+C or Command+C to stop the recording)
adb pull /sdcard/movie.mp4
By default, the screen recording is limited to 3 minutes only. If you want to set a condition like clip duration, resolution in pixels, and video bitrate, you can use the following commands:
adb shell screenrecord --size 1920x1080 /sdcard/movie.mp4
I used a 1920x1080p resolution here for an example. You can change the value according to your needs.
Next, use the following command to set the video duration:
adb shell screenrecord --time-limit 120 /sdcard/movie.mp4
Similarly, you can also set the bitrate of the video output. For example, I am setting the bitrate to 4MBPS. The code would be as follows:
adb shell screenrecord --bit-rate 4000000 /sdcard/movie.mp4
ADB Shell commands for copy, move & paste
Execute the following command to copy and paste files/folders:
adb shell
and then enter the following:
cp /sdcard/The_Shawshank_Redemption.mp4 /sdcard/Movies
(Replace the source file and destination value as per your requirements.)
Next, to move a file or a folder from one location to another, you can execute the following:
mv /sdcard/The_Shawshank_Redemption.mp4 /sdcard/Movies
(Replace the source file and destination value as per your requirements.)
To move a file from one location to another with a new name, use the following:
mv /sdcard/facebook.apk /sdcard/facebook-mod.apk
ADB Shell KeyEvent commands (for advance users)
Using the Shell KeyEvent commands, you can trigger certain functions perform by hardware buttons and UI options on your Android device. Execute these codes only if you know about tweaking VM heap to improve performance.
adb shell input keyevent 3 // Home btn
adb shell input keyevent 4 // Back btn
adb shell input keyevent 5 // Call
adb shell input keyevent 6 // End call
adb shell input keyevent 26 // Turn Android device ON and OFF. It will toggle device to on/off status.

Low-lying valence band states and intrinsic photoconductivity in crystalline anthracene and tetracene
N. Geacintov, M. Pope
Research output: Contribution to journalArticlepeer-review
Abstract
The wavelength dependence of the intrinsic photoconductivity of anthracene and tetracene single crystals has been measured with photon energies up to 6.5 eV. Both materials exhibit three peaks or shoulders in the 3.0-6.5-eV range. The photoconductivity spectra are interpreted by comparing them to the kinetic energy distributions of external photoemitted electrons. The energy sequence of the photoconductivity peaks is in good agreement with characteristic energy losses suffered by the externally emitted photoelectrons. The decreases in the photocurrent, as the photon energy is increased, are shown to arise at energies at which transitions from lower-lying valence states set in. When transitions from lower-lying valence states are involved, the energy of the final state may be below the photoconductivity threshold energy and the current decreases. The energy sequences of the valence states are compared to theoretical HMO and extended-Hückel-method calculations. Finally, the absorption spectra of these crystals are related to the photoconductivity action spectra.

User:Chrisabelen/Chris Abelen
Christiaan „Chris“ Mathias Maria Abelen (born September 29, 1959) is a Dutch jazz trombonist.
Life and career
Dutch trombonist Chris Abelen (Tilburg, the Netherlands 29 september 1959) started out on trumpet at 11, switching to the bigger horn at 18. He studied classical trombone with Charles Toet and Henri Aarts, and then jazz and improvised music with Willem van Manen, founding member of and first trombonist with the Willem Breuker Kollektief, the band that first called global attention to Dutch improvised music. In 1984, Abelen took over van Manen’s old chair in the Kollektief from short-timer Garrett List, and would tour and record extensively with that band till 1988.
But Abelen had the urge to lead his own groups. At Willem Breuker’s annual Klap op de Vuurpijl festival in 1992, he led a pan-generational, pan-stylistic international tentet (including Ab Baars and Paul Termos in the reeds, tubist Larry Fishkind and Michael Vatcher on drums), showcasing the players with mini-concertos that demonstrate Abelen’s preoccupations with color, texture and mood, as well as his wry indirect sense of humor. The proof’s on the CD Proost (BVHaast).
But that was a one-shot ensemble. Abelen wanted a band. His first post-WBK working group had been a sextet including tenor saxophonist Tobias Delius and bassist Wilbert de Joode, which debuted on an earlier Klap op de Vuurpijl festival (1989). That evolved into a quartet with drummer Martin van Duynhoven—you can hear that lineup on the live title track to Abelen’s 2011 digital sampler Plint—later replaced by Charles Huffstadt. With the Proost tentet’s Corrie van Binsbergen added on electric guitar, this group became the leader’s signature outfit, the Chris Abelen Quintet, another band of distinct individual voices. The pieces could be highly melodic and/or densely busy, and the spontaneous arrangements were fluid, with no fixed solo routines. The composer/leader functioned as traffic cop on trombone: setting the tempos, calling back the melodies. A few pieces from the Quintet’s 1996 debut Dance of the Penguins return on 1999’s What a Romance, to make plain that fluidity and instant arranging. The 2004 follow-up Space was for another tentet: the Quintet plus Ab Baars on clarinet and the Zapp String Quartet.
Over the years Chris Abelen has also toured and recorded with numerous Dutch jazz and new music ensembles, including Willem van Manen’s Contraband, I Compani, Paradise Regained Orchestra, Eric van der Westen Octet, Dick de Graaf Septet, and J.C. Tans + Rockets. After leaving the Willem Breuker Kollektief, he assisted Breuker in preparing parts for performance and scores for publication. As an outgrowth of that work, Chris now works as a professional engraver, serving publishers such as Boosey & Hawkes (London), Donemus and Universal; orchestras including the Los Angeles Philharmonic, Royal Concertgebouw Orchestra, Asko/Schönberg Ensemble and Metropole Orchestra; and other composers including Louis Andriessen, Martijn Padding, Willem Jeths, Geert van Keulen, Elmer Schönberger and Bernard van Beurden.
In the 2010s, Abelen took his music in a new direction. In 2016 he released his sixth album, A day at the office, for a septet with a new line-up, and a slightly more pop and even funk orientation, despite the instrumentation: trumpeter Angelo Verploegen, Floris van der Vlugt and Tini Thomsen on high and low reeds, and a new guitar/bass/drums rhythm section: Thijs Huijbens, Ulrich Wentzlaff-Eggebert and Yonga Sun. This album is part of a new project in which Abelen collaborates with lyricist/librettist Bastiaan Geleijnse, one of the cartoonists behind the acclaimed Dutch newspaper comic Fokke en Sukke. In 2018 came the sequel Songs on the eve of dismissal, with vocals by Lorena del Mar (Abelen’s first record with a singer). The Chris Abelen 7’s Live at the BIM (2020) is drawn from a June 2019 concert at Amsterdam’s Bimhuis, featuring songs from the latter album; performances from that concert are posted on YouTube and Vimeo.

Power Query M Primer (Part 8): Types—The Temporal Family
, , , ,
Temporal—something related to time (not to be confused with the word temporary). M offers several temporal types: date, time, datetime, datetimezone and duration.
This group of types has a lot in common, so we’ll explore it a little differently than the types we’ve encountered previously. First, we’ll introduce each type and look at its unique facets. Then, we’ll examine how the various types in this family play together (like common functionality they share).

Power Query M Primer (Part 7): Types—Numbers
, , , ,
In our exploration of Power Query’s types, number is next!
You might think that working with numbers would be so simple we’d hardly need to talk about them. However, there’s a got-ya that can bite: if you’re not careful, you can end up with arithmetic not producing the results you expect! After we go over M’s syntax for numeric literals, we’ll talk about this potential pain-point and how to not let it cause unexpected complications.
Also, in M, columns can be tagged to identify the specific kind of numbers they contain. Properly setting this subtype can improve performance and storage as well as enhance the default formatting used for the column’s values. We’ll learn how to do this (it’s easy!).

Power Query M Primer (Part 6): Types—Intro & Text (Strings)
, , , ,
Examine an executing Power Query mashup under a microscope and what to you see? Data pulsing down pathways between expressions. Increase your microscope’s magnifying power. As you zoom in on one of the flows, what you’re viewing transforms from a blurred stream of data into the individual data items that make up that flow.
As you study what you see, you notice that the data items flowing by fit into groupings based on the kind of value they contain: some hold text, others are made up of a date, a time or a datetime; yet others are true/false values, then there are numbers…and it looks like there are even more categories beyond these!
In this post, we’ll begin exploring these categories—we’ll begin exploring the kinds of values supported by the M language. In programming parlance, these kinds of values” are called types.
Types can have special behaviors associated with them. For example, date and time have a special rule around addition: add a date and a time together and you get back a datetime! We’ll investigate these special rules.
Also, we’ll discuss the literal syntax associated with each type. In this context, ”literal” implies that you literally want to write out a value in code. You might, for example, literally want to set variable rate to the hand-selected value of 100. The syntax you use to code up the expression that produces the literal value you want is called literal syntax. Different types have different literal syntax rules. We’ll talk about these rules, as well.
There’s a lot to cover. In this post, we’ll explore the specifics of text (strings). If we explored all of the types in this post, it would get mighty long, so we’ll save the others for later.

Automating Column Name Renames
, , ,
Ever rename a table’s column names to transform their style from what makes sense in the database world to what looks attractive in a reporting environment?
Perhaps a data source returns field names like:
user_id, username, first_name, last_name, is_active_user
In your report, you’d like these columns to show up as:
User ID, Username, First Name, Last Name, Is Active User
The obvious way to achieve this is to use the query editor to manually rename each column. For five columns in one table (such as the above example), hand-transforming their names isn’t too tedious. However, imagine a report that uses ten or twenty tables, each with twenty or thirty columns—and it’s a different story.

Power Query M Primer (Part 5): Paradigm
, , , ,
To improve our understanding of how Power Query works, let’s step back from the pieces and look at the paradigm—the methodology that M is built around. Conceptually, how does M work? How does it think? What makes it tick? The particulars, like variables, let expressions, functions and identifiers, are all important, but if we only focus on details, we might miss the big picture. We might not see the forest because we’re looking so intently at the trees. Let’s step back and learn about M’s modus operandi.
Without an awareness of M’s methodology, we might spend our days writing M code perplexed by certain behaviors, puzzled by why M seemingly doesn’t let us do certain things we might want to do and perspiring as we waste effort trying to mimic code patterns from other languages that are needless in M.

Power Query M Primer (Part 4): Variables & Identifiers
, , , ,
Up until now, we’ve used variables without talking much about their specifics. Since we’re operating under the assumption that you have at least a little experience with another programming or scripting language, how we’ve used variables has probably made sense.
However, there might be differences—perhaps even significant differences—between how variables work in other languages you’ve used with and how they behave in the Power Query M language. Let’s spend some time exploring variables and related concepts to clear up any lurking confusion and position you to take full advantage of what M offers.
We’ll start with a brief recap of the main unit where we define variables: the let expression. Then, we’ll talk about how variables (and other things) are identified. Related to identifiers is scope, so we’ll cover that, too. Next time, we’ll expand our understanding of how variables work by learning about M’s paradigm.

Power Query M Primer (part 3):
Functions: Function Values, Passing, Returning, Defining Inline, Recursion
, , , ,
Not only can you define and invoke functions (as we covered in part 2), you can also pass them around. The ability to pass a function around without invoking it gives lots of flexibility.
Sounds complex? Yes, in words, but not necessarily in practice. If you’ve touched the Power Query M language, you’ve probably already passed functions around—just perhaps without realizing about it.
Then there’s the mysterious each. It shows up a lot in code generated by the query editor. What does it actually mean or do? Turns out, it’s a handy shortcut that can simplify code you write.
We have ground to cover. Let’s get going!

Power Query M Primer (part 2):
Functions: Defining
, , , ,
If you read part 1 in this series, you may have picked up a theme about expressions that produce values: A simple statement, like 1, is an expression that produces a value. let is also an expression that produces a value.
Guess what? A function is an expression that ultimately produces a value. Unlike the expressions we looked at last time, a function only produces this value when it’s invoked.
Usually, parameters are passed to a function when it’s invoked. The function can reference these inputs as it computes what it will return. Continue reading
Power Query M Primer (part 1):
Introduction, Simple Expressions & let
, , ,
Sooner or later, you may find yourself working directly with the Power Query M formula language. Tools like Microsoft Excel’s Get & Transform Data and Microsoft Power BI provide point-and-click interfaces allowing you to build data transformation sequences which behind-the-scenes are implemented in Power Query M. However, these query editors can’t do everything you might need. Sometimes direct editing and authoring of M is required.
Search the Internet and you’ll find many examples showing how to use this language to solve one problem or another but little is out there describing the syntax and paradigm of the language itself. A limited knowledge of these details may be insignificant when simply copying and pasting samples and editing variable and column names. Move beyond this to weaving and writing your own solutions directly in Power Query M and a solid understanding of the language’s syntax, rules and capabilities becomes most helpful.

State of Wisconsin, Plaintiff-Respondent, v. Peter J. McMaster, Defendant-Appellant-Petitioner.
Supreme Court
No. 95-1159-CR.
Oral argument October 31, 1996.
Decided December 13, 1996.
(Also reported in 556 N.W.2d 673.)
For the defendant-appellant-petitioner there were briefs by Daniel P. Fay, Joseph M. Amidon and Law Firm of Daniel P. Fay, S.C., Pewaukee and oral argument by Joseph M. Amidon and Daniel P. Fay.
For the plaintiff-respondent the cause was argued by Maureen McGlynn Flanagan, assistant attorney general, with whom on the brief was James E. Doyle', attorney general.
DONALD W. STEINMETZ, J.
The issue in this case is whether the Double Jeopardy Clause of the Fifth Amendment to the United States Constitution prohibits the criminal prosecution of the defendant for violations of Wis. Stat. §§(346.63 and 346.65, subsequent to the administrative suspension of his driving privileges under Wis. Stat. § 343.305(7) and (8). We hold that the criminal prosecution of the defendant after the administrative suspension of his driving privileges is permitted because we find that the primary purpose of Wis. Stat. § 343.305 is remedial.
There is no dispute over the facts in this case. On July 16, 1994, Peter McMaster received a citation for operating while under the influence of an intoxicant in violation of Wis. Stat. §§ 346.63(l)(a) and 346.65. McMaster had previous convictions for violations of the drunk driving statutes and was therefore charged with a criminal offense. A blood alcohol test administered after his arrest showed an ethanol concentration of 0.178 percent in McMaster's blood. Because his blood alcohol concentration was above the prohibited level, McMaster's driving privileges were administratively suspended for six months in accordance with Wis. Stat. § 343.305(7). A citation was also issued charging McMaster with a violation of Wis. Stat. § 346.63(l)(a) and (b).
After his initial appearance before the trial court, McMaster filed a motion to dismiss, claiming that the criminal prosecution under Wis. Stat. § 346.63 was barred by the Double Jeopardy Clause of the Fifth Amendment to the United States Constitution. McMaster argued that because the State had already punished him for driving while intoxicated by revoking his driving privileges, he could not also be criminally prosecuted for the same offense. The circuit court for Waukesha County, Judge J. Mac Davis, denied the motion to dismiss based on its finding that the purpose of Wis. Stat. § 343.305 is remedial and therefore does not constitute punishment for double jeopardy purposes. McMaster was found guilty of operating a motor vehicle with a blood alcohol content in excess of 0.10 percent contrary to Wis. Stat. § 346.63(l)(b) and sentenced to 90 days in the county jail.
McMaster appealed to the court of appeals. The court of appeals affirmed the circuit court judgment of conviction. In its decision, the court found that Wis. Stat. § 343.305(7) and (8) is remedial in nature, noting that the fact that the statute may also serve some deterrent and punitive goals does not make its primary purpose one of punishment. State v. McMaster, 198 Wis. 2d 542, 543 N.W.2d 499 (Ct. App. 1995). Despite McMaster's urging, the court declined to consider this case under the United States Supreme Court case Department of Revenue of Montana v. Kurth Ranch, 511 U.S. 767 (1994), because the holding in Kurth Ranch is limited to situations where taxes are imposed on illegal activities. Instead, the court found that the statute should be considered under United States v. Halper, 490 U.S. 435 (1989). Thus the court of appeals held that under Halper, Wis. Stat. § 343.305(7) and (8) is primarily remedial and does not constitute punishment for a double jeopardy claim.
This case presents a question of constitutional interpretation and a determination of statutory purpose. Whether a statute is considered punishment is a finding of constitutional fact and is an issue of law. State v. Woods, 117 Wis. 2d 701, 715, 345 N.W.2d 457 (1984). Therefore, this court may decide the issue independently of the circuit court or the court of appeals. State v. Thierfelder, 174 Wis. 2d 213, 218, 495 N.W.2d 669 (1993).
A party challenging a statute must show it to be unconstitutional beyond a reasonable doubt. State v. Carpenter, 197 Wis. 2d 252, 263, 541 N.W.2d 105 (1995). There is a strong presumption in favor of the constitutionality of the statute. See id. Therefore, McMaster bears "the burden of overcoming the strong presumption that [Wis. Stat. § 343.305(7) and (8)] does not subject a person to multiple punishment." Id. at 264. A careful analysis of the statute itself in light of controlling precedent is necessary to determine if the challenged statute is in fact violative of the Double Jeopardy Clause.
Historically, the United States Supreme Court has held that civil sanctions imposed in separate proceedings from a criminal prosecution stemming from the same incident do not violate the Double Jéopardy Clause of the Fifth Amendment to the United States Constitution. For example, in Various Items of Personal Property v. United States, 282 U.S. 577 (1931), the Waterloo Distilling Corporation was ordered to forfeit a distillery, warehouse, and denaturing plant on the ground that the corporation conducted its business in violation of federal law. The corporation had been convicted of criminal violations prior to the initiation of the forfeiture proceeding and argued that the forfeiture action violated the Double Jeopardy Clause. Basing its decision in part on long-standing common law principles, the Court unanimously held that the clause was inapplicable to civil forfeiture actions. The Court did not again consider a double jeopardy case involving civil forfeiture until 40 years later, when it reaffirmed the rule of Various Items. In One Lot Emerald Cut Stones v. United States, 409 U.S. 232 (1972) (per curiam), the Court upheld a civil forfeiture of jewels following an acquittal on a smuggling charge against a double jeopardy challenge. In United States v. One Assortment of 89 Firearms, 465 U.S. 354 (1984), the Court unanimously upheld the civil forfeiture of firearms following the acquittal of the gun owner on a charge of the illegal sale of firearms. The Court stated that "[u]nless the forfeiture sanction was intended as punishment, so that the proceeding is essentially criminal in character, the Double Jeopardy Clause is not applicable." 89 Firearms, 465 U.S. at 362.
The Court in 89 Firearms concluded that whether a statute is criminal and punitive, or civil and remedial, is a matter of statutory interpretation. As such, the Court adopted a two-prong test established in United States v. Ward, 448 U.S. 242, 248 (1980), to aid courts in the exercise of statutory interpretation:
'Our inquiry in this regard has traditionally proceeded on two levels. First, we have set out to determine whether Congress, in establishing the penalizing mechanism, indicated either expressly or impliedly a preference for one label or the other. Second, where Congress has indicated an intention to establish a civil penalty, we have inquired further whether the statutory scheme was so punitive either in purpose or effect as to negate that intention.'
89 Firearms, 465 U.S. at 362-63 (citations omitted). The theme in all of these cases is consistent: forfeitures of this type are primarily remedial sanctions that do not constitute punishment for purposes of a double jeopardy analysis.
Despite the consistent trend in Various Items and its progeny, three United States Supreme Court cases in recent years have created some confusion in the area of double jeopardy jurisprudence. In 1989, the Supreme Court decided United States v. Halper, 490 U.S. 435 (1989). Halper involved a situation where a man was convicted of 65 counts of violating the criminal false-claims statute involving $585 actual loss. After he was sentenced in the criminal proceeding, the government brought an action under the civil False Claims Act, exposing Halper to a potential liability of $130,000. Because the Court found that the penalty was "entirely unrelated" to the actual damages suffered, it held that the civil penalty was a "second punishment" in violation of the Double Jeopardy Clause. Halper, 490 U.S. at 447-49. The Court noted that "the labels 'criminal' and 'civil' are not of paramount importance," for "a civil as well as a criminal sanction constitutes punishment when the sanction as applied in the individual case serves the goals of punishment." Id.
The Halper decision seemed to indicate the beginning of a changing tide in modern jurisprudence, particularly with respect to the civil/criminal distinction. It was followed by the Court's decision in Austin v. United States, 509 U.S. 602 (1993). In Austin, the government initiated civil forfeiture proceedings against a body shop and a mobile home after the owner pleaded guilty to a drug offense. Relying on the distinction in Halper between punitive and remedial goals, the Court held that the Eighth Amendment's Excessive Fines Clause applies to in rem civil forfeiture proceedings and, because the forfeiture at issue did not serve solely a remedial purpose, it was invalidated by the Court. Id. at 622.
The case of Department of Revenue of Montana v. Kurth Ranch, 511 U.S. 767 (1994), shed more confusion on the proper means of analyzing statutes to determine if they are punitive in nature. In Kurth Ranch, the Court concluded that the imposition of a drug tax on the parties after their criminal conviction for drug offenses was, in this case, a violation of double jeopardy because the tax could fairly be characterized as punishment. The Court cited to Halper, but rejected the Halper mode of analysis to determine whether a statute is remedial or punitive. Kurth Ranch, 511 U.S. at —, 114 S.Ct. at 1948. Instead, the Court decided that the imposition of the tax after the criminal prosecution violates double jeopardy because it applies only to an illegal activity and, in fact, is imposed only after the arrest of a person for an illegal activity. Kurth Ranch, 511 U.S. at —, 114 S.Ct. at 1947.
There has been some confusion as to whether Halper, Austin, and Kurth Ranch represent a shifting tide in double jeopardy jurisprudence, and under what situations they will apply. Fortunately, the United States Supreme Court has cleared up this confusion with its recent decision in Ursery v. United States, — U.S. —, 116 S.Ct. 2135 (1996). Ursery involved forfeiture proceedings against property allegedly used to manufacture marijuana which were started after the criminal prosecution of the defendant. The appellate court decided that under Halper and Austin civil forfeitures could categorically be deemed to constitute punishment. The Supreme Court reversed, holding that in rem civil forfeitures are neither "punishment" nor criminal for the purposes of the Double Jeopardy Clause. Relying on Various Items, One Lot Cut Emerald Stones, and 89 Firearms, the Court reasoned that it has had a history of viewing in rem forfeitures subsequent to a criminal proceeding as not violative of double jeopardy because they do not impose punishment.
Ursery analyzes the defendant's double jeopardy claim under the two-prong Ward test advocated by the Court in 89 Firearms. This decision in Ursery adds another tool for analyzing the nature of a statute. Perhaps more importantly, however, Ursery also clarifies and limits the holdings in Halper, Austin, and Kurth Ranch. The Court notes that neither Halper, Austin, nor Kurth Ranch was meant to overrule the well-established cases involving civil forfeitures. In fact, the Court explains that each of those decisions must be limited in its holding:
In sum, nothing in Halper, Kurth Ranch, or Austin, purported to replace our traditional understanding that civil forfeiture does not constitute punishment for the purpose of the Double Jeopardy Clause. Congress long has authorized the Government to bring parallel criminal proceedings and civil forfeiture proceedings, and this Court consistently has found civil forfeitures not to constitute punishment -under the Double Jeopardy Clause. It would have been quite remarkable for this Court both to have held unconstitutional a well-established practice, and to have overruled a long line of precedent, without having even suggested that it was doing so. Halper dealt with in personam civil penalties under the Double Jeopardy Clause; Kurth Ranch with a tax proceeding under the Double Jeopardy Clause; and Austin with civil forfeitures under the Excessive Fines Clause. None of those cases dealt with the subject of this case: in rem civil forfeitures for purposes of the Double Jeopardy Clause.
Ursery, — U.S. — , 116 S.Ct. at 2147 (emphasis added).
The situation in the case at bar is not identical to that in any of the cited Supreme Court cases. Wisconsin Statutes § 343.305 does not fall squarely into any of the categories set out in Ursery: it is not a civil penalty as in Halper; it is not a tax as in Kurth Ranch; it has nothing to do with the Excessive Fines Clause as in Austin; and it is not quite a civil forfeiture as in Ursery. However, Wis. Stat. § 343.305(7) and (8) is most similar in character and in purpose to an in rem civil forfeiture "designed primarily to confiscate property used in violation of the law" to protect society from harm. See Ursery, — U.S. —, 116 S. Ct. at 2145. Consequently, this court will proceed under the two-prong Ward analysis as advocated in 89 Firearms and Ursery to determine both the legislative intent and the punitive or remedial nature of the statute. An exploration of the statute itself and its history in light of Wisconsin case law is instructive in this regard.
Whether a criminal prosecution for drunk driving offenses after the administrative suspension of driving privileges violates the Double Jeopardy Clause is an issue of first impression in Wisconsin. However, this court has had the opportunity to explore similar challenges to other statutes under the Double Jeopardy Clause. Most recently, this court faced a double jeopardy challenge to civil commitments under Wisconsin's Sexually Violent Person Commitments statute in State v. Carpenter, 197 Wis. 2d 252, 541 N.W.2d 105 (1995). In Carpenter, the court held that double jeopardy is not violated where the parties were convicted of sex offenses and later faced civil commitment proceedings, because the principal purposes of the commitment were to protect the public and to treat the offenders.
The Carpenter court adopted the standard for determining whether the Double Jeopardy Clause has been violated from State v. Killebrew, 115 Wis. 2d 243, 340 N.W.2d 470 (1983). In Killebrew, the court held that administrative discipline for an escape from prison does not preclude criminal prosecution for the same incident because the administrative action does not constitute punishment. The court noted that "[gjovernmental action is punishment under the double jeopardy clause if its principal purpose is punishment, retribution or deterrence. When the principal purpose is nonpunitive, the fact that a punitive motive may also be present does not make the action punishment." Id. at 251. Applying this standard, the court in Carpenter explains that "a civil sanction is violative of the Double Jeopardy Clause if it 'may not fairly be characterized as remedial, but only as a deterrent or retribution.'" Carpenter, 197 Wis. 2d at 264, quoting Halper, 490 U.S. at 448-49.
While it is accepted in Wisconsin that civil sanctions can constitute punishment, the analysis centers on whether the sanction is" 'so extreme and so divorced from the Government's damages and expenses as to constitute punishment' to which double jeopardy can attach." State v. Thierfelder, 174 Wis. 2d 213, 228, 495 N.W.2d 669 (1993), quoting Halper, 490 U.S. at 442. In Thierfelder, this court held that the Double Jeopardy Clause did not bar criminal prosecution for two offenses involving intoxicated use of a motor vehicle subsequent to a civil judgment in a municipal traffic ordinance action arising from the same incident. The court explained that the defendant failed to demonstrate that the civil sanctions could be characterized as cririiinal penalties. Thierfelder, 174 Wis. 2d at 229.
Perhaps the best way to determine whether a statute is criminal and punitive, or civil and remedial, is through an analysis under the two-prong Ward test as advocated by the Supreme Court in 89 Firearms and Ursery. Even before Ursery was decided, this court adopted the Ward test to analyze double jeopardy challenges. See Carpenter, 197 Wis. 2d at 264; State v. Kramsvogel, 124 Wis. 2d 101, 114, 369 N.W.2d 145 (1985), cert. denied, 474 U.S. 901 (1985). Applying this test to the case at hand, this court must consider 1) whether the legislature intended Wis. Stat. § 343.305 to be a remedial civil sanction, and 2) whether there are aspects of Wis. Stat. § 343.305 that are so punitive either in effect or nature as to render the overall purpose to be one of punishment.
In applying the first prong of the test to Wis. Stat. § 343.305, this court may consider the intent of the legislature, the legislative history of the statute, and the historical treatment of the statute by the courts. See Ursery, — U.S. —, 116 S. Ct. 2135. While there is no express legislative intent contained within the statute itself, the history of the statute clearly indicates the legislature's intent that Wis. Stat. § 343.305 serve as a remedial civil sanction. For example, when administrative revocation was first proposed, the Department of Transportation was directed to study the feasibility and the likely results of administrative license revocation or suspension. Comparing the proposed Wisconsin law to the similar, existing Minnesota law, the report noted that in the first six years of the implementation of the program, alcohol-related revocations increased from 14,000 to 36,000, and traffic deaths decreased from 3.00 to 1.98 per million miles traveled. Wisconsin Department of Transportation, Administrative revocation of drunk drivers in Wisconsin: a legislative report, at 5 (1985). The report asserts that "there may be other factors that contributed to these documented improvements in highway safety, but administrative revocation was definitely a positive factor and played a significant role." Id. The report later asserts that many other states have experienced improvements in highway safety after adopting administrative revocation programs, pointing out that Iowa had a 15 percent decrease in nighttime drunk driving fatalities, and Oklahoma saw a 20 percent decrease in fatalities and a 41 percent decrease in all drinking-related incidents. Id. at 7-8. Finally, the report explains that other states have experienced increased levels of drunk driving enforcement without correlating increases in law enforcement personnel as a result of their administrative revocation programs. The report states that "[t]his increase resulted from a general feeling among law enforcement officers that their efforts in enforcing the OWI law had a direct, visible and positive impact on highway safety." Id. at 9.
The results of the DOT report clearly indicate that the passage of Wis. Stat. § 343.305 was aimed toward promoting public highway safety, but further support of this goal can be found in the legislative drafting file for this statute. In a letter found in the drafting file written on January 12,1987, a defense attorney admits that the new drunk driving laws such as those contained in Wis. Stat. § 343.305 serve the important remedial goal of protecting public safety. The author writes that "[although we already represent persons charged with drunk driving, we have generally supported these changes as necessary for public safety." Letter from Steven P. Doyle, Attorney at Law, to John Medinger (January 12, 1987) (found in drafting file for 1987 Wis. Act 3). The letter further notes that the "law is good in theory because it gets drunk drivers off the road." Id. The statute was intended by the legislature to serve as a civil remedial sanction to protect innocent people on the highways. A February 9,1987, analysis of the bill just four days after it was passed indicates that the administrative license suspension will be effective because it accomplishes the same purpose as the former method of pretrial loss by judicial review "without the court backlog and delay problems." Memorandum from the Assistant General Counsel for the Wisconsin Department of Transportation to the Act 337 Technical Committee Members (February 9, 1987) (found in drafting file for 1987 Wis. Act 3).
Finally, we conclude that the legislature intended Wis. Stat. § 343.305 as a civil remedial sanction because of the historical treatment of the statute by this court. This court has noted in several cases that the policy behind Wis. Stat. § 343.305 is "to facilitate the identification of drunken drivers and their removal from the highways." State v. Neitzel, 95 Wis. 2d 191, 193, 289 N.W.2d 828 (1980). Accord State v. Nordness, 128 Wis. 2d 15, 27, n.5, 381 N.W.2d 300 (1986). This court also agreed that the statute serves this remedial goal in State v. Brooks, 113 Wis. 2d 347, 359, 335 N.W.2d 354 (1983), concluding that the general purpose behind laws relating to operating while under the influence of intoxicants is "to get drunk drivers off the road as expeditiously as possible and with as little possible disruption of the court's calendar." Id. at 359. Although these cases were all decided prior to the passage of the administrative license suspension provisions of Wis. Stat. § 343.305, they speak to the overarching goal of all drunk driving laws in this state. Considering the legislative history of the statute and its historical treatment by this court, we conclude that the legislature intended the administrative license suspension, Wis. Stat. § 343.305(7) and (8),. to serve as a civil remedial sanction.
Despite the obvious remedial purpose of the statute, this court would be remiss to pretend that the administrative license suspension does not serve some deterrent effects. However, the test is not whether the statute serves some deterrent or punitive goals; rather, the inquiry involves determining whether the statute is so punitive in nature or effect as to render it punishment for purposes of the Double Jeopardy Clause. See Ursery, — U.S. —, 116 S. Ct. at 2147. McMaster argues that the suspension of his driving privileges is extremely punitive in nature. Given the nature of the problem addressed by Wis. Stat. § 343.305, drunk driving, the interest the government has in removing the driver from the road is compelling. The fact that the administrative license suspension also inconveniences the defendant and might act as a deterrent is inconsequential to the overall purpose of public safety.
In State v. Schulz, 100 Wis. 2d 329, 302 N.W.2d 59 (Ct. App. 1981), the court held that a finding of guilt for violating a county ordinance does not bar criminal prosecution on the homicide by intoxicated user charge. The court explained that Schulz could lose his license, be forced to attend driver safety school, and be imprisoned for failure to pay his forfeiture, all in addition to the original forfeiture. However, "[t]hese penalties are not so punitive in purpose or effect to negate the intent of the legislature." Id. at 331. The court proceeds to state that "[l]oss of license.. .is not so punitive as to cause us to conclude that jeopardy should attach." Id.
The statute serves to protect the safety of all who travel on Wisconsin's public streets and highways. It is not intended primarily as a punishment, and its effects are not so punitive as to render it as such. There are adequate procedural guidelines in place to ensure that the defendant will not face undue "punishment." After a person's license has been administratively suspended, he or she is entitled to an administrative hearing to review the suspension within 30 days after the person files a notice with the Department of Transportation. Wis. Stat. § 343.305(8)(b). Additionally, "a person aggrieved by the determination of the hearing examiner may have the determination reviewed by the court hearing the action" related to the suspension. Wis. Stat. § 343.305(8)(c)l and 2. If the person is not happy with the circuit court decision, he or she may appeal to the court of appeals, and a person not happy with a municipal court determination may appeal to the circuit court. Wis. Stat. § 343.305(8)(c)3. Finally, any person who has his or her license administratively suspended under Wis. Stat. § 343.305 may apply for an occupational license at any time. Wis. Stat. § 343.305(8)(d). These protections indicate that the purpose of the statute is not to punish drunk drivers, but simply to keep drunk drivers off the roads for the safety and well-being of the general public.
As previously noted, the burden to rebut the presumption of constitutionality falls on McMaster in this case. In Killebrew, Thierfelder, Kramsvogel, and Carpenter, this court has rejected the defendants' challenges to civil statutes as violative of the Double Jeopardy Clause. In all of these cases, the court found that the defendant had failed to meet his or her burden of proving that the statute had a criminal or punitive purpose, nature, or effect. Just like the defendants in those cases, McMaster has "failed to show that the principal purpose of the statute [Wis. Stat. § 343.305] is punishment, retribution, or deterrence so as to render it punishment." See Carpenter, 197 Wis. 2d at 272. Further, McMaster has "failed to show that the statute has sufficient punitive characteristics" to take it out of the realm of a remedial civil sanction and to render it punishment. See id.
Based on a careful application of the two-prong Ward test, we conclude that the legislature intended Wis. Stat. § 343.305 to serve as a civil remedial sanction. We further conclude that the statute is not so punitive in effect and nature as to render it punishment for purposes of a double jeopardy analysis. For these reasons, we affirm the court of appeals and hold that the Double Jeopardy Clause of the Fifth Amendment to the United States Constitution does not prohibit the criminal prosecution of the defendant for violations of Wis. Stat. §§ 346.63 and 346.65, subsequent to the administrative suspension of his driving privileges under Wis. Stat. § 343.305(7) and (8).
By the Court. — The decision of the court of appeals is affirmed.
McMaster was charged with a violation of Wis. Stat. § 346.63(l)(a) and (b). Wis. Stat. § 346.63 provides, in relevant part, as follows:
(1) No person may drive or operate a motor vehicle while:
(a) Under the influence of an intoxicant or a controlled substance or a combination of an intoxicant and a controlled substance, under the influence of any other drug to a degree which renders him or her incapable of safely driving, or under the combined influence of an intoxicant and any other drug to a degree which renders him or her incapable of safely driving; or
(b) The person has a prohibited alcohol concentration.
McMaster was charged under this section because he had previous convictions under Wis. Stat. § 346.63 in the previous five years. Wisconsin Statute § 346.65 provides, in relevant part, as follows:
Penalty for violating sections 346.62 to 346.64.
(2) Any person violating s. 346.63 (1):
(a) Shall forfeit not less than $150 nor more than $300, except as provided in pars, (b) to (e).
(b) Shall be fined not less than $300 nor more than $1,000 and imprisoned for not less than 5 days nor more than 6 months if the total number of suspensions, revocations and convictions counted under s. 343.307 (1) equals 2 in a 5-year period, except that suspensions, revocations or convictions arising out of the same incident or occurrence shall be counted as one.
Wis. Stat. § 343.305(7) and (8) provides, in relevant part:
(7) Chemical Test; Administrative Suspension, (a) If a person submits to chemical testing administered in accordance with this section and any test results indicate a prohibited alcohol concentration, the láw enforcement officer shall report the results to the department and take possession of the person's license and forward it to the department. The person's operating privilege is administratively suspended for 6 months.
(b) If a person who was driving or operating or on duty time with respect to a commercial motor vehicle submits to chemical testing administered in accordance with this section and any test results indicate any measured alcohol concentration above 0.0, the law enforcement officer may take possession of the person's license and retain the license for 24 hours. The person may reclaim a seized license in person or request return of the license by mail. The law enforcement officer shall issue a citation for violation of s. 346.63 (7) (a) 1., issue citations for such other violations as may apply and issue an out-of-service order to the person for the 24 hours after the testing, and report both the out-of-service order and the test results to the department in the manner prescribed by the department. If the person is a nonresident, the department shall report issuance of the out-of-service order to the driver licensing agency in the person's home jurisdiction.
(8) Chemical Test; Administrative Suspension; Administrative and Judicial Review, (a) The law enforcement officer shall notify the person of the administrative suspension under sub; (7) (a). The notice shall advise the person that his or her operating privilege will be administratively suspended and that he or she has the right to obtain administrative and judicial review under this subsection. This notice of administrative suspension serves as a 30-day temporary license. An administrative suspension under sub. (7) (a) becomes effective at the time the 30-day temporary license expires. The officer shall submit or mail a copy of the notice to the department.
The Double Jeopardy Clause provides that no person shall "be subject for the same offence to be twice put in jeopardy of life or limb...." U.S. Const, amend. V.
The ultimate holding of State v. Killebrew, 115 Wis. 2d 243, 340 N.W.2d 470 (1983), was superseded by a statutory change eliminating "statutory good time." See State v. Fonder, 162 Wis. 2d 591, 595, 469 N.W.2d 922 (Ct. App. 1991). However, the "principal purpose" test applied in Killebrew has not been affected.
Cases decided in other jurisdictions in recent years overwhelmingly have recognized that administrative license suspension following a drunk driving arrest or refusal to submit to required testing is primarily remedial in purpose and effect so that a subsequent criminal prosecution does not violate double jeopardy. See Allen v. Attorney General of Maine, 80 F.3d 569, 577 (1st Cir. 1996) (administrative license suspension under Maine law "represents a reasonable effort to protect the public from motorists who have demonstrated a dangerous propensity to drink before they drive;" because sanction is primarily remedial, subsequent criminal prosecution is not barred on double jeopardy grounds). Accord United States v. Imngren, — F.3d —, 1996 WL 614637 (4th Cir. 1996); State v. Reichenberg, 915 P.2d 14 (Idaho 1996); State v. Kocher, 542 N.W.2d 556 (Iowa 1996); State v. Hanson, 543 N.W.2d 84 (Minn. 1996); State v. Mayo, 915 S.W.2d 758 (Mo. 1996), cert. denied, — U.S. —, 117 S. Ct. 61 (1996); State V. Gustafson, 668 N.E.2d 435 (Ohio 1996); State v.

Strengthening Steel Bridge Beams with Fiber Reinforced Polymers (FRP)
Description:
Developing effective and economical means to increase the load carrying capacity of short- and medium-span steel bridges is a challenging and important task for state departments of transportation (DOTs). According to the National Bridge Inventory (NBI), there are 96,052 off-system bridges in the US with steel-beam super structures. Of these, 13,784 have structural evaluation numbers of 4 or below indicating that they are either currently in need of repair or replacement, or that the need for repair or replacement is imminent. The average age of these off-system bridges is 50 years. As such, these structures were not designed with current or future load demands in mind. The increasing load demands and decreasing capacity of these structures due to aging necessitates strengthening or replacement activities. Given that for many communities an off-system bridge may be the only feasible means to transport people and goods into and out of the community, prolonged closures for replacement or repair activities is often not a viable option. Existing repair methods, such as bolting or welding steel plates or sections to the girders requires heavy lifting equipment which may not be easily available in remote areas. Further, these techniques increase the self-weight of the structure thereby limiting the actual live load increase that can be realized through the strengthening effort. Taken collectively, these constraints highlight the urgent need for the development of an effective and economical repair approach for the short- to medium-span bridges that serve rural and remote communities.
Research over the past 20 years has demonstrated that fiber reinforced polymers (FRPs) can be used in various forms to improve the serviceability and strength of steel bridge girders through flexural strengthening (Mertz and Gillespie, (1996); Sen and Libby, (2001); Miller et al., (2001); Tavakolizadeh and Saadatmanesh (2003a,b)). Recent technological advancements, such as the development of high modulus carbon FRP (HM CFRP) (Rizkalla et al., 2007) and carbon FRP (CFRP) strand sheets (Tabrizi et al., 2015) further improved the effectiveness of using CFRP materials to strengthen steel bridge beams. In addition to flexural strengthening, recent research has demonstrated the potential to use FRP composites to enhance the stability of plate elements for shear strengthening applications (Okeil et al., 2009, Kazem et al., 2016). While the effectiveness of these techniques has been demonstrated, there still remain several key barriers to the adoption of these technologies by state DOTs:
i)
Since FRP materials are bonded to the surface of a steel beam using polymeric adhesives, correct surface preparation of the steel is essential to the effectiveness of the system. The predominant surface preparation technique used in the majority of the previous research is grit blasting to a white or near-white metal finish. Given that older structures commonly used lead-based paints, wide-spread grit blasting of the structure would require costly environmental controls, thereby limiting the usefulness of the repair technique.
ii)
Effective methods for inspecting FRP-strengthened steel beams, particularly to ensure the integrity of the bonded interface after construction and over time, have not been developed. Bridge engineers have cited concerns about the inability to effectively inspect the quality of installation and the long-term bond integrity of FRP-strengthened beams as a barrier to the adoption of this technology.
iii)
The traditional approach to selecting adhesives for bonding FRP to steel is based on the strength characteristics (often tensile strength) of the adhesive. However, recent findings suggest that the adhesive toughness also plays an important role in the bond performance. The design of the bonded joint, and the selection of suitable adhesives for bonding (including both strength and durability considerations) is not well understood.
iv)
Various methodologies have been proposed to facilitate the design of FRP-based systems for strengthening steel bridges. None of the existing guidelines have been prepared in a format that is compatible with the AASHTO LRFD Specifications, and none include a reliability-based calibration of the reduction factors that is consistent with the LRFD formulation.
v)
A comprehensive assessment of the initial and life-cycle costs of an FRP-based repair for a steel-girder bridge as compared to the costs of a traditional repair has not been presented. Quantitatively demonstrating the potential cost savings of this type of strengthening system is important to stimulate the adoption of this technology.
Addressing the deterioration of off-system bridges is consistent with the US vision for transportation infrastructure as articulated in Beyond Traffic 2045 (2015). The implications on accessibility to under-served communities and the importance to the movement of people and goods is well defined. Developing effective and economical techniques for strengthening off-system steel bridges is an important aspect of this broader vision which requires additional investigation to facilitate adoption.
Objective:
i) Establish effective surface preparation techniques for bonding FRP to steel surfaces that minimizes the disruption of lead-based paint on older structures,
ii) Identify inspection techniques that can be used to confirm the bond line integrity in FRP-strengthened steel beams,
iii) Provide material and design specifications to direct the selection of adhesives and surface preparation techniques to facilitate proper bond design,
iv) Assess the durability of FRP-strengthened steel beams and effect of exposure to harsh environmental conditions on strength,
v) Calibrate reduction factors in the LRFD format to facilitate adoption of the strengthening system for bridge design and repair applications, and
vi) Complete a comprehensive life-cycle cost analysis to demonstrate in which scenarios the adoption of FRP strengthening for steel bridges is economically feasible.
Benefits:
According to the NBI, there are over 13,000 off-system steel girder bridges in the US with a structural evaluation number of 4 or below. These structures are either immediately or imminently in need of rehabilitation or strengthening to maintain these vital links in the national transportation infrastructure network. This corresponds to nearly 2% of all of the bridges in the nation. Given that the average age of these off-system bridges is 50 years, this problem will only continue to grow. With a total of over 96,000 off-system steel girder bridges in the NBI (13% of bridges nationwide) the potential impact of the proposed research is dramatic. The development and widespread implementation of an effective and economical system to strengthen or repair these bridges would shorten closure times of these structures for maintenance, repair and replacement efforts thereby minimizing the disruptions to the communities they serve. Further, an economical strengthening option could postpone or eliminate the need for replacements thereby freeing agency budgets to address other pressing challenges.

The first research effort conducted in the US to rehabilitate steel bridge girders using composites was sponsored by the Florida DOT, conducted by the University of South Florida and documented in 1994, (Sen et al., 2001). A total of six steel-concrete composite beams were strengthened using different configurations of CFRP composites and tested to failure. This early testing demonstrated the effectiveness of this strengthening and repair technique. Subsequently another study was conducted through NCHRP IDEA Contract NCHRP-93-ID011 (Mertz and Gillespie, 1996). In that study, four different configurations of glass and carbon FRP strengthening were evaluated through a series of small-scale beam tests. Two large-scale beam fatigue tests were also conducted to evaluate the performance of the externally-bonded strengthening under simulated traffic loading. Since then research has been conducted at various institutions around the US and the world. The international Institute on FRP in Construction (IIFC) working group on strengthening steel structures maintains a database of publications that are related to strengthening and repair of steel structures with composites. As of 2014 that database included 325 journal papers on the subject. Research in the area has continued to-date. This extensive body of research has established confidence in the potential to use FRP composites to strengthen steel bridge beams. However, to date, the barriers to adoption listed above still remain un-addressed.
Implementation:
It is anticipated that state bridge and bridge maintenance engineers will be responsible for implementing the research findings. To date there have been at least three documented field/demonstration projects to investigate the use of externally bonded FRP materials for strengthening steel bridge beams in the US including in Delaware (Miller et al., 2001), Iowa (Wipf et al., 2005) and Kentucky (Peiris and Harik, 2015). In all of these applications, the DOT personnel interacted closely with subject matter experts at nearby Universities to coordinate the design and installation of the repairs. In order to facilitate the broad adoption of the research findings by state DOTs it is important that design guidance be provided in a format that can easily and directly be implemented by DOT engineers independently from University researchers. It is anticipated that AASHTO Sub-Committee on Bridges and Structures, T-6 (Fiber Reinforced Polymer Composites) would play a key role in the development and approval of such a document.
Relevance:
All DOTs will be able to use the findings of this project to address the large aging inventory of steel bridges.

More Ram = Slower Boot/ Program Load Times?
Hey everyone,
I am running Win Xp Pro 32 bit on a custom machine. I pulled out my 2 1 GB of DDR2 800 Ram and added 2 2GB sticks of DDR2 800 Ram and the boot time as well as some programs seem to load slower. I have a 512mb video card and I think XP is using another .3 gb of ram because CPU-Z is showing 3.2, which was around what I expected it to show. Would putting in the Old ram help, or am I just being paranoid. Thanks and let me know if you need a DXDIAG.

More about more slower boot program load times
1. In general the more the memory per module, the more is the latency of the ram, but this will not make the system very much slow, indeed a 0.5 % slow for the programs which can also run in the previous memory configuration very fine and will be much faster for the programs which need a lot of memory which was inadequate for the previous memory configuration
I think the problem with your system is the Operating System, Windows Xp 32 bit. Windows Xp 32 bit has a problem in handling 4Gb of memory
try to shift to a 64 bit Operating System or remove a 2 GB stick and replace with a 1 GB previous stick so that, you have a 3GB of memory
2. if your processor is a 64 bit, there is a chance to utilize the ram more
try to use PAE(physical address extension)
you may try to refer the links
http://projectdream.org/wordpress/2007/04/25/windows-xp-supports-4gb-of-ram-period/
http://www.howtofixcomputers.com/bb/ftopic117376.html
google for the thing
3. Unless you have "Quick memory test" turned on in the BIOS or standard memory test turned OFF, boot times will be longer. But more memory should give you a more responsive system.
You can always test the memory if you suspect a problem.
4. Are you sure that CPU_Z is showing 3.2 Gb of ram?
It should be exact how much you have installed ! The POST and the Task Manager must show 3.2...

Title: Atomistic simulations of brittle crack growth.
Abstract
Ceramic materials such as lead zirconium titanates (PZT), low temperature co-fired ceramics and silica glasses are used in several of Sandia's mission critical components. Brittle fracture, either during machining and processing or after many years in service, remains a serious reliability and cost issue. Despite its technological importance, brittle fracture remains poorly understand, especially the onset and propagation of sub-critical cracks. However, some insights into the onset of fracture can be gleaned from the atomic scale structure of the amorphous material. In silica for example, it is well known [1] that the Si-O-Si bonds are relatively weak and, in angle distribution functions determined from scattering experiments, the bonds exhibit a wide spread around a peak at 150. By contrast the O-Si-O bonds are strong with a narrow peak in the distribution around the 109 dictated by the SiO{sub 4} tetrahedron. In addition, slow energy release in silica, as deduced from dissolution experiments, depends on the distribution of 3-fold and higher rings in the amorphous structure. The purpose of this four month LDRD project was to investigate the atomic structure of silica in the bulk and in the vicinity of a crack tip using molecular dynamics simulations. Changes in the amorphousmore » structure in the neighborhood of an atomically sharp tip may provide important clues as to the initiation sites and the stress intensity required to propagate a sub-critical crack.« less

• A set of numerical analyses of crack growth was preformed to elucidate the influence of microcracking on the fracture behavior of microcracking brittle solids and composites. The random nucleation, orientation and size effects of discrete nucleating microcracks and resulting interactions are fully accounted for in a hybrid finite element model. The results obtained from the finite element analysis are compared with the continuum description of the microcracking. Although continuum description can provide a reasonable estimation of shielding, it fails to resolve the details of micromechanism of toughening resulting from microcracking, since not every shielding event during the course of crackmore » extension corresponds to an increase in the R-curve. Moreover, as seen in the composite cases, the local events leading to toughening behavior may not be associated with the microcracking even in the presence of a large population of microcracks.« less
• In this project we developed t he atomistic models needed to predict how graphene grows when carbon is deposited on metal and semiconductor surfaces. We first calculated energies of many carbon configurations using first principles electronic structure calculations and then used these energies to construct an empirical bond order potentials that enable s comprehensive molecular dynamics simulation of growth. We validated our approach by comparing our predictions to experiments of graphene growth on Ir, Cu and Ge.

• A vibrating-beam method was used to determine the elastic modulus of graphite rods. The frequency and apparent modulus were determined as a function of compression end loading. Following fracture of the rod, the frequency and apparent modulus were decreased. At a compression and loading of about 0.83 MPa (120 psi), crack closure was sufficient for the fractured rod to behave similarly in vibration to the unfractured rod. Thus, the fractured material behaves in a bimodular fashion and crack closure can be achieved to enable unimpeded stress transfer across the fracture surface during vibration.
• The critical stress intensity factors for propagating cracks, K/sub ID/, was experimentally found to decrease with increasing crack velocity. K/sub ID/ was measured using rapidly wedged double cantilevered beam specimens. The crack length versus time was continuously recorded using electro-potential techniques. The specimens were fractured at temperatures well below the brittle to ductile transition temperature. The crack velocity in these specimens varies continuously but is typically in the range of 100 to 200 m/s. The analysis of fully dynamic crack propagation in double torsional beam specimens was solved in closed analytic form. The solutions for rotational rate loading and formore » constant applied torque, predict constant crack velocity. The crack velocity is given by the applied rate of rotation, the magnitude of the applied torque and specifics about the beam. The maximum crack velocity is the torsional wave speed. The use of the analysis is to deduce K/sub ID/ during crack propagation without measuring the crack velocity directly. The measurements of static, dynamic loading and propagating crack, stress intensity factors establishes that rate is an important variable in specifying the stress intensity factor for fracture.

PYTHON introduction
We will be using the Python programming language with the NumPy library during the whole semester. Make sure you are comfortable with these so that you don't spend more time dealing with python/numpy issues than solving the assignment tasks.
For the case you are not too sure about your Python/NumPy skills, have a look here: http://cs231n.github.io/python-numpy-tutorial/, ask your uncle (duckduckgo, google) or your teacher.
Start by reading General information for Python development and cloning the assignment template repository.
Matrix manipulation with NumPy
In the first part of today’s assignment, you will start with some simple matrix manipulation tasks.
TRY TO AVOID USING LOOPS FOR MATRIX MANIPULATION IN YOUR PROGRAM!
Although numpy has a matrix class, we will not be using that. Instead, we will use the array class for representing matrices, vectors, images, lists, etc. We will import numpy using
import numpy as np
Your goal is to complete a function output = matrix_manip(A, B), where A and B are input matrices (represented by np.array). The matrix_manip function should return a python dict containing the results of the operations described below.
To have some data to work with, lets use the following matrices A and B:
A = np.array([[16, 2, 3, 13],
[ 5, 11, 10, 8],
[ 9, 7, 6, 12],
[ 4, 14, 15, 1]])
B = np.array([[3, 4, 9, 4, 3, 6, 6, 2, 3, 4],
[9, 2, 10, 1, 4, 3, 7, 1, 3, 5]])
Your function should work on general input matrices, not only for the A and B shown here or for matrices with the same dimensions.
1. Find the transpose of the matrix A and return it in output['A_transpose']. Example result:
>> output['A_transpose']
array([[16, 5, 9, 4],
[ 2, 11, 7, 14],
[ 3, 10, 6, 15],
[13, 8, 12, 1]])
2. Select the third column of the matrix A and return it in output['A_3rd_col'].
>> output['A_3rd_col']
array([[ 3],
[10],
[ 6],
[15]])
Hint: Don't forget python and numpy use 0-based indexing. Make sure your output dimensions are correct!
3. Select last two rows from last three columns of the matrix A and return the matrix in output['A_slice'].
>> output['A_slice']
array([[ 7, 6, 12],
[14, 15, 1]])
4. Find all positions in A greater then 3 and increment them by 1. Afterwards add a new column of ones to the matrix (from right). Save the result to output['A_gr_inc'].
>> output['A_gr_inc']
array([[17, 2, 3, 14, 1],
[ 6, 12, 11, 9, 1],
[10, 8, 7, 13, 1],
[ 5, 15, 16, 1, 1]])
Hint: Try > operator on the whole matrix. The output dtype should be the same as the input dtype. Some numpy functions do not make copies of the inputs, but return 'views' of the input arrays instead. Make sure you don't corrupt the other results when computing output['A_gr_inc']
5. Create matrix C such that $C_{i,j} = \sum_{k=1}^n A\_gr\_inc_{i,k} \cdot (A\_gr\_inc^T)_{k,j}$ and store it in output['C'].
>> output['C']
array([[499, 286, 390, 178],
[286, 383, 351, 396],
[390, 351, 383, 296],
[178, 396, 296, 508]])
Hint: No loops are needed, try it on a paper with a 2×2 matrix.
6. Compute $\sum_{c=1}^n c \cdot \sum_{r=1}^m A\_gr\_inc_{r,c}$, store in output['A_weighted_col_sum']:
>> output['A_weighted_col_sum']
391
Hint: Use broadcasting of the element-wise multiplication, np.arange, np.expand_dims and np.sum. Finally convert the output to Python float (as indicated in the docstring) by calling float( … ).
7. Subtract a vector $(4,6)^T$ from all columns of matrix B. Save the result to matrix output['D'].
>> output['D']
array([[-1, 0, 5, 0, -1, 2, 2, -2, -1, 0],
[ 3, -4, 4, -5, -2, -3, 1, -5, -3, -1]])
8. Select all column vectors in the matrix D, which have greater euclidean length than the average length of column vectors in D. Store the results in output['D_select']
>> output['D_select']
array([[ 0, 5, 0, -2],
[-4, 4, -5, -5]])
Simple data task in Python
In this part of the assignment, you are supposed to work with a simple input data which contains images of letters. We will use similar data structures later on during the labs. Do the following:
1. The following variables are stored in the data_33rpz_basics.npz data file:
• images (3D array of 2000 10×10 grayscale images)
• alphabet (letters contained in the images, not full alphabet is included)
• labels (indexes of the images into Alphabet array).
2. Load and access them as follows
loaded_data = np.load("data_33rpz_basics.npz")
loaded_data['images']
3. Have look at the image with the montage function supplied in the template:
import matplotlib.pyplot as plt
plt.imshow(montage(images), cmap='gray')
plt.show()
Hint: Try to use
%matplotlib notebook
after importing matplotlib.
4. For a given letter, compute its mean image. This means taking all images in the dataset displaying that letter, and making pixel-wise mean. Use your name initials (if present in the dataset) and save them as initial1_mean.png and initial2_mean.png (use any letter if any of your initials is not present in the dataset). Round the mean image to integers and return it in the uint8 dtype.
• For the purpose of mean image calculation, complete the function compute_letter_mean:
letter_mean = compute_letter_mean(letter_char, alphabet, images, labels)
where letter_char is a character (e.g. 'A', 'B', 'C') representing the letter whose mean we want to compute, alphabet, images and labels are loaded from the provided data, and letter_mean is the resulting mean image.
5. Compute an image feature x - a single number characterizing an image. It is defined as:
x = sum of pixel values in the left half of image - sum of pixel values in the right half of image
Then make a histogram of feature values of all images of a letter. Complete a function for the feature histogram computation:
lr_histogram = compute_lr_histogram(letter_char, alphabet, images, labels, num_bins)
where letter_char is a character representing the letter whose feature histogram we want to compute, alphabet, images and labels are loaded from the provided data, num_bins is the number of histogram bins and lr_histogram is the resulting histogram (num_bins long vector containing counts of items in the corresponding bins).
• For reference the following histogram was computed for letter A with 10 bins:
>> compute_lr_histogram('A', alphabet, images, labels, 10)
array([ 1, 1, 3, 6, 12, 27, 24, 20, 5, 1])
• Hint: use np.histogram function to compute the histogram.
• Plot feature histograms of your initials into one figure to compare them and save the figure as initials_histograms.png.
• WARNING: make sure you use correct x-axis on the plot. (is it 1-10, or something in orders of 1000s?)
• Try to make the figure useful - label the axes, give it a title, … Would your grandma (or you two weeks from now) understand what is shown in the figure?
• Do the histogram plots make sense? Could you recognize the letter only by looking at its lr histogram?
• hint: use matplotlib bar function.

BEIJING (Reuters) - Earnings growth for China’s industrial firms cooled in July after accelerating for three straight months, reinforcing expectations the economy will slow over coming quarters as higher lending costs and property market curbs bite. Profits earned by China’s industrial companies in July rose 16.5 percent from a year earlier to 612.7 billion yuan ($92.18 billion), slower than the previous month, the statistics bureau said on Sunday. That was the slowest rate of growth since profits rose 14.0 percent in April. Profit growth slowed in July because some companies halted production due to especially high temperatures, He Ping of the National Bureau of Statistics bureau said in a statement along with the data release. For the first seven months of the year, the firms notched up profits of 4.25 trillion yuan, a 21.2 percent jump from the same period last year and a touch slower than the 22.0 percent annual growth in the January-June period. Earnings for the industrial sector were boosted by a year-long, government-led construction spree, which fueled demand and prices for building materials. Government efforts to shut older, heavily polluting mines and factories have given commodity prices fresh impetus in recent weeks. Strong earnings, in turn, have opened the way for fresh investment, and given the country’s long ailing “smokestack” industries more cash flow which could, in theory, be used to start paying down a mountain of debt. Aluminum Corp of China Ltd (Chalco) (601600.SS) (2600.HK) reported on Aug. 17 that its six-month net profit rose more than tenfold year-on-year as it cashed in sky-high aluminum prices. A day later, China’s top state-run aluminum smelter said it will be making further investment in raising output in the second half of the year. The manufacturing sector, which accounts for 88 percent of industrial profits, saw profit growth of 18.1 percent in the first seven months, trending down only slightly from 18.5 percent in the first half. But analysts say economic growth is starting to slow as measures to cool heated property prices and clamp down on riskier forms of lending put the brakes on activity. Beijing’s efforts to reduce debt have pushed up lending rates, signaling tighter margins and tougher operating conditions for firms as debt servicing costs go up - a sign of slowing earnings growth over coming months. In addition to slower profit growth, Sunday’s data showed profit margins and account receivables days outstanding weakened slightly in July after improving for the last two months. Industrial firms’ net profit margin fell to 6.09 percent in July from 6.11 in June. Weaker performance in the industrial sector is in line with July economic data that was mostly weaker than expected, after forecast-beating GDP growth of 6.9 percent in the first half. At the end of July, industrial firms’ liabilities were 6.6 percent higher than a year earlier, compared with a 6.4 percent increase at the end of June. Profits at China’s state-owned firms were up 44.2 percent at 927.4 billion yuan in January-July, compared with a 45.8 percent rise in the first six months. The data covers large companies with annual revenue of more than 20 million yuan from their main operations.

Pirton, Hertfordshire
Pirton is a large village and civil parish three miles northwest of Hitchin in Hertfordshire, England. The population of the civil parish at the 2011 census was 1,274.
The church, rebuilt in 1877, but with the remains of its 12th-century tower, is built within the bailey of a former castle, Toot Hill. Pirton Grange, which was remodelled in the 18th century, is in the north of the parish, and is a particularly interesting, moated Elizabethan house with a timber-framed gatehouse. Hammonds Farm and Rectory Farm, with its tithe barn, are also Elizabethan.
Pirton first appeared in official records in the Domesday Book in 1086 within the hundred of Hitchin. The village was then known as Peritone (meaning 'Homestead of Pears')
The Icknield Way Path passes through the village on its 110 mile journey from Ivinghoe Beacon in Buckinghamshire to Knettishall Heath in Suffolk. The Icknield Way Trail, a multi-user route for walkers, horse riders and off-road cyclists also passes through the village.
There are two churches in Pirton - one Methodist, one Anglican. There is a village school which teaches children from reception to Year 6. Many students continue on at Hitchin Priory. | WIKI |
Jay-Z arbitration dispute temporarily halted after rapper wins injunction over discrimination | TheHill
Rapper Jay-Z won a court battle in his trademark dispute with Iconix Brand Group Inc. on Wednesday after a court temporarily halted his arbitration proceedings over the lack of African-American arbitrators. The rapper argued that the lack of racial diversity among eligible arbitrators at the American Arbitration Association (AAA) who could rule on his case was unfair discrimination, The New York Times reported. A judge in the New York State Supreme Court in Manhattan imposed an injunction on the arbitration until a hearing on Dec. 11. This temporarily halts the proceedings. Jay-Z and the brand were supposed to each pick four arbitrators from AAA’s “Large and Complex Cases” database, including the four supplied from the association, and narrow down the list together until both sides agreed. But the rapper argued in his court petition obtained by the Times that he was “confronted with a stark reality” while he was looking at the list — he could not identify a single African-American arbitrator. The AAA has only three potential African-American arbitrators — two men and one woman — that could hear the case, but one was already involved with Iconix in related litigation. "It would stand to reason that prospective litigants — which undoubtedly include minority owned and operated businesses — expect there to be the possibility that the person who stands in the shoes of both judge and jury reflects the diverse population," the music star's petition said. Jay-Z, whose legal name is Shawn Carter, claims the lack of diversity is discrimination under the New York state constitution and New York City human rights law. The AAA declined to comment to the Times. The rapper is locked in a legal battle with the clothing brand after he sold his Rocawear line to the company for $204 million in 2007, Reuters reported. Iconix sued Jay-Z in federal court after he began selling New Era baseball caps with a paper airplane logo from his new company, Roc Nation, which the company said violated the Rocawear sales agreement. After Jay-Z countersued, the two parties entered arbitration. View the discussion thread.

A house designed to blend in with nearby homes built in the 18th century is very much a 21st-century home inside.
Old Meets New in Sag Harbor
On the outside, the house at 43 Suffolk Street in Sag Harbor, N.Y., was designed to blend in with nearby homes that were built in the 18th century. Inside, it is very much a 21st-century home. Its radiant heated bathroom floors, gas fireplaces and security system can be controlled with an iPhone, and a hydraulic lift transports a vehicle down to the home’s lower level, where, like a treasured sculpture, the car sits in a glass-enclosed showcase visible from a spacious lounge and a wine room. | NEWS-MULTISOURCE |
Power over Ethernet (PoE) Explained
Power over Ethernet (PoE) technology enables ordinary Ethernet network cables to function as power cords. In a PoE-enabled network, direct electrical current (DC) flows over the network cable together with normal Ethernet data traffic. Most PoE devices follow either IEEE standard 802.3af or 802.3at.
Power over Ethernet was designed for use with portable and wireless electronic equipment like Wi-Fi access points (APs), webcams, and VoIP phones.
PoE allows network devices to be installed in ceilings or wall spaces where electric outlets are not within easy reach.
A technology unrelated to PoE, Ethernet over power lines enables ordinary electric power lines to act as long-distance Ethernet network links.
Why Most Home Networks Don't Use PoE
Because homes typically have many power outlets and relatively few Ethernet wall jacks, and many consumer gadgets use Wi-Fi connections instead of Ethernet, the applications of PoE for home networking are limited. Network vendors typically only include PoE support on their high-end and business-class routers and network switches for this reason.
DIY consumers can add PoE support to an Ethernet connection using a relatively small and cheap device called a PoE injector. These devices feature Ethernet ports (and a power adapter) that enables standard Ethernet cables with power.
What Kinds of Equipment Work with PoE?
The amount of power (in watts) that can be supplied over Ethernet is limited by the technology.
The exact threshold of power needed depends on the rated wattage of the PoE source and the power draw of the client devices. IEEE 802.3af, for example, guarantees only 12.95W of power on a given connection. Desktop PCs and laptops generally cannot operate over PoE due to their higher power needs (typically 15W and up), but portable devices like webcams that function at less than 10W can.
Business networks sometimes incorporate a PoE switch through which a group of webcams or similar devices operate. | ESSENTIALAI-STEM |
Pathos (manga)
Pathos is a Japanese manga written and illustrated by Mika Sadahiro. It is licensed in North America by Digital Manga Publishing, which released the first volume on July 22, 2008, and the second on September 23, 2008.
Reception
Leroy Douresseaux says of Pathos that "Rarely are vampires as sexy as they are in Pathos", and favourably compares it to Interview with the Vampire, later describing the story as feeling "timeless", and praising Sadahiro's characterisations. Patricia Beard felt the character designs did not mesh well together, feeling as if they'd been taken from many different subgenres, and disliked the "tawdry and coarse" cover art. Beard felt that the vampire lore in the story was "unusual", and praised Sadahiro's inventiveness and attention to individuality in a particular sex scene. Beard enjoyed the characterisation of Ace in the second volume, but criticised the English adaptation of the second volume as having several jarring moments. | WIKI |
IoT Weather on Android
In a previous post I talked about moving from request-response to using the publish-subscribe pattern. This pattern allows our application parts to listen for changes in a decoupled fashion. This works great with the continuous feed feature of IBM Cloudant. In this iteration I will bring the data to Android, and cover a couple great utilities.
Volley
On the surface, there is not much new or exciting in this Android iteration of the weather data we have been working with over the last several posts. The application starts and loads data via a REST exchange with the same server infrastructure we have been using.
In making that request for the initial data however, I am using a library from Google called "Volley". Volley is a high performance library for managing network communications. It even caches the data on the client for the all too common "destroy" event that comes with device rotation.
JsonObjectRequest request;
request = new JsonObjectRequest(
Request.Method.GET,
getString(R.string.cloud_code),
null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
// Process server response
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d("VOLLEY", error.getMessage());
}
}
);
Volley.newRequestQueue(this).add(request);
Notice that last line. In this case, I am using a static method to initiate the request. You can also create an instance variable, and then queue up multiple requests. You can then in turn cancel requests based on responses you might get, etc. The callbacks also seem to land on the UI thread, so it is easy to update the user interface.
I have commented out the details of "onResponse" for brevity. What happens in there is that the JSON data is marshaled into a domain object called "Weather". A populated instance of the "Weather" class is then sent to an "update()" method to update the user interface.
You might be wondering why I do not just update the user interface right from the response handler - especially seeing as it has easy access to the UI-thread? I extracted that code into a separate method because it will get reused as new data arrives.
PubNub
If you remember, IBM Cloudant has a feature called "continuous feed" which allows us to be notified when changes happen at the database. We catch these changes in our Node.js infrastructure, and then use PubNub to push a message to interested clients.
In this case, our Android device is also an interested client. We use the PubNub Android library in our application to handle new messages - messages that represent that new weather data is available.
pubnub = new Pubnub(
getString(R.string.pubnub_publish),
getString(R.string.pubnub_subscribe)
);
try {
pubnub.subscribe(
getString(R.string.pubnub_channel),
new Callback() {
@Override
public void successCallback(String channel, Object data) {
// Process incoming message
}
}
);
What is interesting here is that the Android client knows nothing about the Node.js server or IBM Cloudant database. Just like the browser-based client in our previous example, the parts and pieces are decoupled thanks to the use of the publish-subscribe pattern.
Weak Reference
The PubNub communication however happens on a separate thread from the UI-thread. That means that it cannot populate the user interface directly. The handler has to get the data over to the UI-thread. This is traditionally done using the Android "Handler" class.
// Get key data
bundle = new Bundle();
bundle.putDouble(KEY_CELCIUS, document.getDouble(KEY_CELCIUS));
bundle.putDouble(KEY_FAHRENHEIT, document.getDouble(KEY_FAHRENHEIT));
bundle.putDouble(KEY_HUMIDITY, document.getDouble(KEY_HUMIDITY));
bundle.putLong(KEY_TIMESTAMP, document.getLong(KEY_TIMESTAMP));
// Assemble message
// Cross-thead communication
message = new Message();
message.setData(bundle);
// Send message
handler.sendMessage(message);
Much like publish-subscribe on client and server, handlers in Android allow decoupled thread to communicate with one another, without knowing about one another. In the PubNub success callback, I place the pertinent data on an instance of the "Bundle" class. That bundle is put into an instance of the "Message" class. The message is then sent via the handler to the UI-thread.
The problem with handlers is that they are known to leak memory if not use properly - and using them properly requires a whole bunch of sophisticated overhead code. The overhead must be written correctly as well in order to prevent leaking memory. This is a lot of work for a simple message that wants to update the user interface.
Android Studio specifically will warn you extensively that you have potentially entered a memory leak zone when you start using the Android "Handler" class.
To make this magic much easier, I use a library from Badoo called "WeakReference". This class encapsulates all the handler nuances for us. We still use it as a typical handler, and it provides the same interface.
handler = new WeakHandler(new Handler.Callback() {
@Override
public boolean handleMessage(Message message) {
Bundle bundle;
Weather weather;
// Get pertinent data
bundle = message.getData();
// Marshall to domain
weather = new Weather();
weather.celcius = bundle.getDouble(KEY_CELCIUS);
... More marshaling ...
// Update user interface
update(weather);
return false;
}
} );
So in this case, the message data arrives into the Android client via PubNub subscribe handler, the pertinent data is marshaled into a bundle, and then sent as a message to the handler. The handler marshals the data from a bundle to an instance of the "Weather" class. The handler is also on the UI-thread, so it has permission to call the "update()" method with the pertinent data.
Long story short then, the "update()" method is extracted for reuse, and that reuse happens from a REST response on the UI-thread, but also a message push from PubNub on a separate thread. Since the REST handler gets a JSONObject, and the subscribe handler (on the UI-thread side), gets a Bundle instance, data must be marshaled to a common domain class.
Next Steps
Including the ~30 or so lines used for import statements, this entire Android application comes in at under 250 lines of code thanks to the use of some very powerful helper libraries. Volley makes REST communication a snap, and WeakReference helps keep your threads talking without leaking memory.
You now have several examples of using IoT data from a Particle Photon on IBM Bluemix to include Node.js, IBM Cloudant, a browser client, and an Android client. There is just one problem - all of these are one-way communication. From here what we really want is to be able to communicate back to the sensor as well; perhaps to take some physical action at the installation.

John Kidd (chemist)
John Kidd (10 September 1775 – 7 September 1851) was an English physician, chemist and geologist who took a leading role in Oxford's "scientific awakening" in the early years of the nineteenth century.
Biography
Kidd was born in Westminster, the son of a naval officer, and was educated at Christ Church, Oxford. He became reader in chemistry at Oxford in 1801, and in 1803 was elected the first Aldrichian Professor of Chemistry. He then voluntarily gave courses of lectures on mineralogy and geology. These were delivered in the dark chambers under the Ashmolean Museum, where William Conybeare, William Buckland, Charles Daubeny and others gained their first lessons in geology. Kidd was a popular and instructive lecturer, and through his efforts the geological chair, first held by Buckland, was established.
Kidd's two geological publications — his Outlines of Mineralogy (1809) and Geological Essay on the Imperfect Evidence in Support of a Theory of the Earth (1815) — have been described as providing "the seeds of an Oxford school of geology," characterized by a distinctive emphasis on diluvial theory. In 1818 he became a fellow of the Royal College of Physicians; in 1822 Regius Professor of Medicine in succession to Sir Christopher Pegge; and in 1834 he was appointed keeper of the Radcliffe Library.
In March 1822 he was elected a Fellow of the Royal Society. In 1830 the president of the Royal Society appointed him as one of the eight authors of the Bridgewater Treatises "on the Power, Wisdom, and Goodness of God as Manifested in the Creation." His treatise on the "Adaptation of External Nature to the Physical Condition of Man," which was published in 1833, offered "a popular rather than a scientific exposition of facts" and set out to protect readers from materialism and the transmutation of species. Kidd refused to "maintain an argument" about natural theology, addressing himself "exclusively to those who are believers." He delivered the Harveian Oration before the Royal College of Physicians in 1836.
Publications
* Outlines of Mineralogy (1809)
* A Geological Essay on the Imperfect Evidence in Support of a Theory of the Earth (1815)

Wikipedia:Sockpuppet investigations/AZ8196/Archive
Evidence submitted by Beyond My Ken
Az81964444 created the article Border War (1910-1918), and he and I had some conflict after I edited it, which included what I interpreted as an attack on me, after what was determined to be incivility on my part – all discussed on on AN/I – which resulted in the editor retiring. I've continued to watch the article, and editor $1LENCE D00600D did some edits to it today. I reverted one of them and left a message on their talk page. The editor's response on my talk page indicated that he was the author of the article. This picqued my curiosity, and I looked back into the history of these editors. What I found is a pattern of a user who edits for a number of months, almost always on articles related to battles – frequently including the Battle of Ambos Nogales, which was created by AZ8196 (other IDs have created other battle articles) – and then drops the ID and starts another. I have tracked the editors back to AZ8196, although they may go farther back than that.
* AZ8196 – created: 30 January 2009 last edit: 26 February 2009 – 62 edits, 25 pages
* (considering the gap between the end of February and the beginning of May, I may be missing an ID here)
* TJ13090 – created: 2 May 2009 last edit: 1 June 2009 – 746 edits, 127 pages
* Aj4444 – created: 5 July 2009 last edit: 30 August 2009 – 2701 edits, 412 pages
* Az81964444 – created: 13 September 2009 last edit: 31 July 2010 – 9334 edits, 1250 pages
* Robertp6165 – created: 5 April 2010 last edit: 27 July 2010 – 36 edits, 2 pages
* $1LENCE D00600D – created: 1 August 2010 most recent edit: 30 August 2010 – 943 edits, 247 pages
The pattern seems deliberate: note that IDs are dropped near the end of a month, and are usually created at the beginning of a month. There's one gap, which I noted above, but otherwise the move from one ID to another is direct and almost immediate. There's only one ID (Robertp6165) which overlaps, and that ID only edited two articles, First Battle of Dragoon Springs (created by TJ13090) and Second Battle of Dragoon Springs, so it may have been created specifically for that purpose.
Wikistalk results for these six editors show considerable overlap, even considering their focus on military-related (actually, battle-related) articles:
* 1 article (War of 1812) edited by 5 of the 6 (all but Robertp6165)
* 5 articles (United States occupation of Veracruz, Battle of Picacho Pass, American Indian Wars, Action of 18 March 2006, First Battle of Dragoon Springs) edited by 4 of the 6 (in 2 different combinations)
* 53 articles edited by 3 of the 6 (in 5 different combinations)
* 185 articles edited by 2 of the 6
* 244 articles in common overall
This is in the context of the 6 IDs having edited 1753 unique pages in their editing careers. (2063 total "unique" pages less 310 overlaps). This means that these 6 IDs have overlapped on about 14% of all the articles they have edited, a high percentage, and unlikely to be the result of coincidence.
I have no evidence that the edits of this editor have been disruptive, but the pattern of starting IDs and then dropping them, without acknowledging the connection, is a concern, since it looks like avoiding scrutiny. If the editor has a legitimate explanation for doing so, that's fine, but if not they should probably be asked to pick one of the IDs to edit from and the rest should be indef blocked, and the user told not to continue to create new accounts. Beyond My Ken (talk) 08:21, 30 August 2010 (UTC)
* I have notified all the accounts listed above. Beyond My Ken (talk) 08:27, 30 August 2010 (UTC)
* Please note that of all these IDs, only one has a block history: Aj4444 has a 24 hour block for personal attacks and harrassment. However, also note that the latest ID, $1LENCE D00600D, has left a rather uncivil message on my talk page in response to my notification of this report, in which he again confirms his identity as Az81964444. Beyond My Ken (talk) 08:38, 30 August 2010 (UTC)
* Looking a little deeper into this, Az8196 created one article, Battle of Ambos Nogales. After the ID stopped editing on 26 February 2009, that artice was subsequently edited by TJ13090 and Az81964444. Beyond My Ken (talk) 17:55, 30 August 2010 (UTC)
* The next editor in line, TJ13090 created 8 articles:
* Battle of Galveston Harbor (1837)
* Battle of Brazos Santiago
* Battle of Brazos_River
* Battle of Bear Valley
* Battle of Puerto Plata Harbor
* Battle of Columbus (1916)
* Traditional Arizona
* First Battle of Dragoon Springs
* With 7 out of these 8 articles, after TJ13090 stopped editing on 1 June 2009, there were multiple edits made by Aj4444 and Az81964444 (with the last also having multiple edits by Robertp6165). The exception is #6, which had multiple edits from Az81964444, but none by Aj4444. Clearly, these IDs are all the same person, continuing to work on the articles they created. Beyond My Ken (talk) 10:11, 30 August 2010 (UTC)
* Next, Aj4444 created 17 articles:
* Battle of Albuquerque
* Battle of Taku Forts (1860)
* Battle of Taku Forts (1858)
* Bombardment of San Juan del Norte
* Battle of Fatshan Creek
* Battle of the Pearl River Forts
* Action of 15 October 1917
* Bombardment of Ancona
* Bombardment of Fort_Stevens
* Action of 17 November 1917
* Battle of Rio de Oro
* Battle of Taku Forts
* Action of 4 May 1917
* Bombardment of Fanning (moved to Fanning Raid by another editor)
* Bombardment of Madras
* Battle of Trindade
* Ernest Martin Jehan
* In all but one of these articles, after Aj4444 stopped editing on 30 August 2009, the articles were edited, sometimes extensively, by Az81964444. The one exception is Fanning Raid, a stub article. Beyond My Ken (talk) 10:26, 30 August 2010 (UTC)
* Similarly, Az81964444 created 96 articles (which I will not list here), and from looking at the Wikistalk results for the two IDs, it seems as if the latest ID, $1LENCE D00600D, has edited most, if not all of them. Once again, we see this editor using a new account to continue working on the articles they created with a "retired" account. Beyond My Ken (talk) 10:32, 30 August 2010 (UTC)
I'm requesting CheckUser, despite the clear behavioral evidence, because I may have missed an ID, and I'm not sure how far data goes back, so I don't know if staleness is an issue or not. Beyond My Ken (talk) 18:22, 30 August 2010 (UTC)
* Regarding XavierGreen's comment below, there was indeed some conflict between Az8196444 and myself, which I noted in the very first sentence of my evidence, including a link to the AN/I report on it. (Here it is again, for those who might have missed it: ) However, I didn't go looking for this, it fell into my lap when $1LENCE D00600D admitted on my talk page that he was the editor who created the article (that is, Az81964444), and I went and looked into it. If that had been the end of it – an editor retiring after some conflict and then returning for a "fresh start" – I would not have filed a report, since this editor appears to me to be basically productive, if a little touchy, but the pattern going back at least four other editors was really too much to ignore. But, even if this was "retaliatory" in some way (and it's not), the evidence shows what the evidence shows, it's pretty undeniable. The easiest thing would be for $1LENCE D00600D to make a statement admitting their behavior, giving a reasonable explanation for it, and pledging not to do it again. I'd be perfectly happy with that, as I'm sure most people in the community would be. I'm not seeking to have this editor blocked or sanctioned, just to put a stop to a rather disruptive, apparently scrutiny-avoiding pattern of behavior.

* Beyond my Ken is right and need to be blocked. No duck blocks can be handed out here IMO. -- DQ (t) (e) 02:26, 16 September 2010 (UTC)
* Just to be clear, my suggestion was not exactly as DeltaQuad states. I suggested that the socks be blocked, but that $1LENCE be allowed to continue editing with a warning not to sock again, except if further checkuser investigation found that XavierGreen was also related. The editor reported here ($1LENCE, AZ81964444 et al.) is quite prolific in the Military History subject area and, on net, a positive asset for the project, so it would be best, in my opinion, if a way could be found to allow them to continue editing, but with acknowledgment that they should do so under one ID. Beyond My Ken (talk) 13:10, 16 September 2010 (UTC)
* I suggesting closing this request without any action taken. No evidence has been presented of an abuse of multiple accounts. If somebody wants to create a new account every month he/she can perfectly do so. Ruslik_ Zero 17:10, 16 September 2010 (UTC)
* Um, not necessarily. Users who create a bunch of accounts disruptively (like this guy) can be blocked; besides, repeatedly creating accounts may well violate WP:SCRUTINY among other things by obfuscating the entire edit history. T. Canens (talk) 05:07, 19 September 2010 (UTC)
* 1) I'm blocking Az81964444. The editor is supposedly "retired" anyway, so there should be no harm done, but this will prevent the account from being reused again.
* 2) I'm going to leave a stern warning for $1LENCE D00600D, that they need to choose one account and stick with it. Any further use of alternate accounts outside of what is permitted at WP:SOCK will lead to sanctions (including an indefinite block). This is due to the lack of evidence that there is any disruption from the account.
* 3) Based on I'm highly doubtful that XavierGreen is a related account. No action against them.
* Broadly agree with Atama, with the addition that I'm also blocking the stale accounts, which are certainly related; and that I'm turning off the autoblock on the accounts, as it is unnecessary. Finally, I don't think sockpuppet tags are appropriate under the particular circumstances here; I would simply redirect the user pages. T. Canens (talk) 17:33, 22 September 2010 (UTC)
* Thanks, I actually went back to undo the autoblock and saw that you'd done that, I'd forgotten to turn that off. (It's likely that the autoblock would have blocked $1LENCE D00600D also, which we don't want.) Redirecting the the user pages is actually better than a sockpuppet template, that was a good idea. -- At am a 頭 17:39, 22 September 2010 (UTC)
* FWIW, not that it makes any difference one way or the other, but as the editor who filed this report, I endorse the admin actions taken. Beyond My Ken (talk) 18:10, 22 September 2010 (UTC)
* I came here via Contributor copyright investigations/$1LENCE D00600D and that ought to be taken into consideration as to whether user:$1LENCE D00600D ought to be indefinitely blocked. -- PBS (talk) 20:57, 17 April 2014 (UTC) | WIKI |

Adding Nanoseconds To Datetime In Python
Python is a high-level, interpreted programming language, designed and developed by Guido van Rossum in the 1990s.
It is known for its simplicity and is one of the most popular programming languages present in the software industry.
One of the most important concepts in python is that of adding nanoseconds to a datetime in python.
Let us consider an example where we have an arbitrary starting datetime, say 30th of March in the year 2022, 11 hours and we need to add 2 nanoseconds to this datetime.
The resulting datetime should be the 30th of March in the year 2022, 11 hours and 2 nanoseconds.
Let us have a look at the different ways of doing this in detail.
Adding Nanosecond using the pandas library in Python
In this method, we use the pandas library to add nanoseconds to a datetime.
To work with these libraries we must first import them using the import statement.
We define a variable start_datetime that stores the starting datetime. The desired starting datetime in this example is 30th of March in the year 2022, 11 hours and we need to add 2 nanoseconds to this.
This is specified using the pandas.to_datetime() function with the parameter passed as the date in string format in the form 30/3/2022 11:00:00, i.e. day month year hours minutes seconds format.
Next, we add 2 nanoseconds to this starting datetime using the pandas.to_timedelta() function by passing the parameter as 2 and unit as ns to specify that we are mentioning nanoseconds.
The result is stored in the variable new_datetime which is later printed.
Let us look at the Python 3 code and corresponding output for this method:
# Importing the required libraries
import pandas as pd
# Starting datetime
start_datetime = pd.to_datetime('30/3/2022 11:00:00')
# Performing the operation
new_datetime = start_datetime + pd.to_timedelta(2, unit = 'ns')
# Printing
print(new_datetime)
Output
2022-03-30 11:00:00.000000002
Unfortunately, using the pandas library is the only way of working with date-time objects at a nanosecond level since the original date-time library can only work up to the millisecond level with the relativedelta() function and up to the microsecond level with the timedelta() function.
Conclusion
In this topic, we have learned the use and advantages of adding nanoseconds to a datetime in a Python program, following some simple running examples of programs, thus giving us an intuition of how this concept could be applied in the real-world situations.

Advice For Choosing The Best Chiropractor
Pain is a part of the human body, especially those who undergo physical pressure due to work or other reasons. Whatever the reasons be, a pain is horrible to bare and anyone undergoing it needs to be treated with proper therapy for immediate and permanent cure.
Choosing the right chiropractor will help you get healed quickly. These experts can offer immediate pain relief assistance for those who are suffering from structural pains in the spinal cord, limb and the neck parts of the body.
People who have chronic back pain will also find a remedy through a chiropractor. This article will help you find out the best chiropractor who can offer you permanent cure from emergency pains and long-lasting pains.
Choosing The Best Chiropractor
1. Service Feedback
When choosing a chiropractor in your area, the first factor you have to look in for is their service feedback given by their previous clients. Check whether they provide this health service in a hygienic environment because infection prone areas can worsen your health conditions. Chiropractors must specialize in offering the best treatments for their patients and should give them lifetime relieves from the pain and sufferings.
If you live in the Oklahoma area, Dr. Marcus Favorite Chiropractor OKC will be a good choice to make; you can also do your research and also consult your friends and colleagues for recommendations based on their personal experience if any.
You can search the internet for feedback and testimonials provided by their previous patients and based on the reviews online you can choose the best chiropractic practitioner to give you good healing therapies. More than any other reviews, personal experiences are more trustable.
2. List of Services
A professional chiropractor must be able to provide a wide range of therapies such as chiropractic cure for people of all ages, including pregnant women and infants. If you are a sports person and faced some injury during your play, the first person who must attend you is a chiropractic expert, because they can understand your body better at that injured point in time.
Acupuncture therapies are also offered as a part of this treatment process. People who are suffering from constant low back pain, neck pain, headache, and sciatic pain shouldn’t delay any further because the list of services offered by a professional chiropractor also includes therapies for your sufferings and pains.
You can make use of this treatment and get a lifetime cure and relief from various traumas and pains.
3. Step by Step Procedure
Always ensure that the chiropractor you choose offers you treatment in a systematic step by step process so that you can get the complete benefit of the treatment. The common steps in the chiropractic treatment can be categorized as pain control, followed by the corrective care and the final stage is the rehabilitation phase.
During every phase of this treatment, when done by the best chiropractor, you can feel the relief and the recovery to your regular life stage by stage. There will be phases of improvement happening to ensure that the treatment procedures are happening consecutively.
4. Key Factors to Look in a Chiropractor
When you are searching for a chiropractor, you have to ensure that they have hands-on experience in this field and have handled several clients and given successful results to them.
Check whether they specialize in offering highly advanced treatment procedures without creating harm or side effects for the patients. They must possess the skill of understanding the human body in a better way, because pains can be felt well, but cannot be explained that easily.
The chiropractor must be able to feel the pain of the patients so that they can provide effective therapy for cure. They must master the art of the language that human body speaks.
5. Consultation Appointment
When you have shortlisted a chiropractor based on your research or the references you have got from your friends or family; now it is your role to fix up a consultation appointment with them to try to explain your pain to them and confirm whether they can offer a remedy for it.
If you find the consultation conversation convincing, you can proceed with treatments and therapies with them. Sometimes, people visit chiropractors even for general health checkups, so if that your case, explain it to the specialist so that they can approach your body accordingly.
It is important that your chiropractor must be able to answer all your queries and give you clarity in every procedure that they are going to be doing on your body.
You must not be left puzzled at any stage of the treatment, and that is the main aspect you have to confirm during the consultation with the specialist. Don’t ever fix up an appointment for treatment before sitting for a consultation session with the specialist as it is important for both the ends.
6. Long-Term Treatment or Specific Treatment
People generally approach a chiropractor either for a long-term treatment which will happen in different phases for years together.
Some other patients will have treatment requirement for a specific complaint or an injury. Regular treatments will have different procedures and approaches than for the specific complaints.
The chiropractor will give treatments that improve the functions of joints and bones in the neck, spine and back area of the body. This is more like a rehabilitation process that will promote the overall health and well being of a person. These kinds of procedures have to be regularly practiced according to the advice of the practitioner.
If needed a chiropractor might also recommend you to undergo a surgery based on your health condition. Generally, this will be applicable for patients who are suffering on a long-term basis. If you find yourself in such a position, always take another opinion before proceeding.
Conclusion
If wellness is the goal of your life and you want to live a normal life like any other person, you have to choose the best chiropractor and get regular treatment for permanent relief.

Azerbaijan says to cease retaliatory military actions in Nagorno-Karabakh
YEREVAN (Reuters) - Azerbaijan said on Sunday it would end fighting with Armenian-backed troops over the breakaway Nagorno-Karabakh region after two days of clashes which have killed dozens. “Having taken into account ...appeals from international organizations, Azerbaijan has decided to unilaterally cease retaliatory military actions and will consolidate yesterday’s territory gains,” RIA news agency quoted the Azeri Defence Ministry as saying. Nagorno-Karabakh lies inside Azerbaijan but is controlled by ethnic Armenians. It has run its own affairs with heavy military and financial backing from Armenia since a separatist war ended in 1994.

Mathematical Modelling
Mathematical modeling is a powerful and versatile tool used in various fields of science, engineering, economics, and beyond. It involves the representation of real-world phenomena using mathematical equations, allowing researchers and decision-makers to gain insights, make predictions, and optimize processes. This comprehensive overview will delve into the fundamentals, types, applications, and importance of mathematical modeling.
Fundamentals of Mathematical Modeling
At its core, mathematical modeling is a process of abstracting complex real-world situations into a simplified mathematical framework. It involves several fundamental components:
1. Mathematical Equations: Mathematical models rely on equations that describe the relationships between different variables. These equations can be linear, nonlinear, differential, or stochastic, depending on the nature of the problem being modeled.
2. Variables: In any mathematical model, there are input variables, output variables, and parameters. Input variables are the quantities that influence the system being modeled, output variables are the quantities of interest, and parameters are constants that define the behavior of the model.
3. Assumptions: All models are simplifications of reality, and they require assumptions to be made. These assumptions help in reducing the complexity of the problem and make it mathematically tractable. However, these assumptions should be carefully chosen to ensure that the model remains relevant and useful.
4. Validation and Verification: Mathematical models need to be validated and verified to ensure their accuracy and reliability. Validation involves comparing the model’s predictions to real-world data, while verification checks the correctness of the mathematical formulation.
Steps and concepts involved in mathematical modeling
1. Formulating the Problem: The first step in mathematical modeling is to clearly define the problem you want to study or the system you want to analyze. This involves identifying the relevant variables, parameters, and constraints.
2. Choosing a Mathematical Framework: Once the problem is defined, you need to select the appropriate mathematical framework or approach to represent it. This could involve differential equations, algebraic equations, optimization techniques, statistical models, or other mathematical tools.
3. Building the Model: With the chosen mathematical framework, you construct a mathematical model that describes the relationships among the variables and parameters in the system. This often involves making assumptions and simplifications to create a tractable model.
4. Solving the Model: Depending on the complexity of the model, solving it can involve analytical techniques (finding exact solutions), numerical methods (approximate solutions), or a combination of both. Computational tools and software are often used for numerical simulations.
5. Validation and Calibration: After constructing and solving the model, it’s essential to validate it by comparing its predictions to real-world data. If the model doesn’t match observations, it may need to be calibrated or refined.
6. Analysis and Interpretation: Once the model is validated, you can use it to analyze the system or problem. This may involve sensitivity analysis to understand how changes in parameters affect outcomes, optimization to find optimal solutions or other forms of analysis.
7. Prediction and Scenario Testing: Mathematical models can be used to make predictions about future behavior or to test different scenarios. This is valuable for decision-making and planning.
8. Communication of Results: The results and insights gained from the mathematical model should be communicated effectively to stakeholders, whether they are scientists, engineers, policymakers, or the general public.
9. Iterative Process: Mathematical modeling is often an iterative process. As new data becomes available or the problem evolves, the model may need to be updated and refined.
10. Uncertainty and Assumptions: It’s important to acknowledge and address uncertainties in the model, as well as the assumptions made during its construction. Sensitivity analysis and Monte Carlo simulations are common techniques for handling uncertainty.
Types of Mathematical Models
Mathematical models come in various forms, each tailored to address specific types of problems and systems:
1. Deterministic Models: These models assume that the system’s behavior is entirely predictable and governed by fixed rules. Examples include linear equations, polynomial equations, and ordinary differential equations.
2. Stochastic Models: In contrast to deterministic models, stochastic models consider randomness and uncertainty in the system. They often involve probability distributions and are used for modeling complex, unpredictable systems like financial markets and biological populations.
3. Continuous Models: Continuous models represent systems that change continuously over time or space. Examples include fluid flow equations, heat transfer equations, and population growth models.
4. Discrete Models: Discrete models deal with systems that change in discrete steps or intervals. Examples include cellular automata, agent-based models, and Markov chains.
5. Static Models: Static models describe systems at a single point in time, without considering how they evolve over time. They are often used for optimization problems and equilibrium analysis.
Challenges and Limitations of Mathematical Modeling
While mathematical modeling is a powerful tool, it comes with challenges and limitations:
1. Data Availability: Models heavily rely on data, and their accuracy is limited by the quality and quantity of available data. In some cases, data may be scarce or unreliable.
2. Assumption Sensitivity: Models are built on assumptions, and their results can be highly sensitive to these assumptions. Small changes in assumptions can lead to significantly different outcomes.
3. Complexity: Real-world systems are often highly complex, and simplifications are necessary for modeling. However, overly simplistic models may not capture important nuances.
4. Uncertainty: Models cannot eliminate uncertainty entirely, especially in stochastic systems. They can only provide estimates of probabilities and outcomes.
5. Computational Resources: Some models, particularly those involving large-scale simulations, require significant computational resources, which can be expensive and time-consuming.
Conclusion
Mathematical modeling is a versatile and indispensable tool in understanding, predicting, and optimizing real-world phenomena across a wide range of disciplines. Its applications are vast, from physics and engineering to economics and social sciences. While mathematical modeling has its challenges and limitations, it continues to play a vital role in advancing knowledge and facilitating informed decision-making. As technology and data collection methods advance, the potential for mathematical modeling to address

was early morning before Elsie fell asleep. She slept late. Ina knocked at her door, and found it bolted and went away again. Later, when Elsie was dressed and went into the sitting-room, she found the whole party assembled there. Lord Horace was talking excitedly. "Eight thousand pounds worth of gold. By jove, it's a haul!" he was saying.
Eight thousand pounds! The words brought a thrill to Elsie. "What are you talking about?" she exclaimed. "What does it mean?"
"It means the most daring robbery that ever was committed. The gold escort robbed eight miles from Goondi at three o'clock this morning—six armed policemen to five bushrangers," said Hallett.
"And the devil, as they say, in the shape of a black horse," put in Lord Horace. "I should like to have the chance of a shot at Abatos. What fools they were not to aim at the horse. 'Pon my soul, it's the most extror'nary thing. Etheridge, the sergeant, swears the men are all in armour."
"Copying the Kellys," said Lady Horace.
"Copying the mediaeval duffers rather. It's a better sort of armour than the Kellys.

Bubble Shuttle II - Schmale: Bentho-pelagischer Transport methanotropher Mikroorganismen über Gasblasen
Gas bubble releasing seep sites are relevant methane sources in aquatic systems. In the vicinity of these sites, methanotrophic microorganisms in the sediment and water column play a key role in controlling the methane flux into the atmosphere. Recent studies in the water column surrounding hydrocarbon seeps indicated an elevated abundance and activity of methanotrophic microorganisms in the near field of gas bubble plumes. During our pilot studies conducted at the Coal Oil Point Seep region in California (DFG project “Transport of methane oxidizing microorganisms from the sediment into the water column (Bubble Shuttle)” (GZ:SCHM 2530/3-1), we could show for the first time that methanotrophic bacteria were transported by gas bubbles from the sediment into the water column. The fundamental goal of our follow-up project is to evaluate the importance of such a transport mechanism on the pelagic methane turnover at these seep sites. Multidisciplinary studies at different seep locations located in the Coal Oil Point seep field and the North Sea will help us to discuss the different environmental factors, which control the transport efficiency of the bentho-pelagic gas bubble mediated exchange process. By integrating lab-based incubation experiments we will study the activity of seep-associated benthic methanotrophic bacteria in the pelagic environment. Additional molecular biological analyses will be used to test our hypothesis that the gas bubble transport mechanism impacts the diversity of pelagic methanotrophic bacteria at seep sites. Field studies at a Blowout location in the North Sea and the integration of oceanographic measurements and models will be used to establish a budget for pelagic methanotrophic bacteria in the near field of seep sites. Overall, this approach will help us to discuss the impact of the bubble transport mechanism on the abundance of methanotrophic bacteria and the pelagic methane sink.

Sovereignty's Promise: The State as Fiduciary (Oxford Constitutional Theory)
Constitutional thought is frequently fascinated by the justification and boundaries of country energy. It asks: Can states legitimately direct and coerce non-consenting topics? in the event that they can, what limits, if any, constrain sovereign strength?
Public legislations is anxious with the justification and bounds of judicial strength. It asks: On what grounds can judges 'read down' or 'read in' statutory language opposed to the plain goal of the legislature? What limits, if any, are applicable to those routines of judicial strength?
This publication develops an unique fiduciary conception of political authority that yields novel solutions to either units of questions. Fox-Decent argues that the kingdom is a fiduciary of its humans, and that this fiduciary courting grounds the state's authority to announce and implement legislation. The fiduciary nation is conceived of as a public agent of necessity charged with ensuring a regime of safe and equivalent freedom. while the social agreement culture struggles to flooring authority on consent, the fiduciary thought explains authority almost about the state's fiduciary legal responsibility to admire criminal ideas constitutive of the rule of thumb of legislation and attentive to public power's indifference to consent.
The writer starts off with a dialogue of Hobbes's belief of legality and the matter of discretionary strength in administrative legislation.
Drawing on Kant, he then sketches a thought of fiduciary kin, and develops the argument via 3 elements. half I indicates that it truly is attainable for the nation to face in a public fiduciary dating to its humans via a dialogue of Crown-Native fiduciary relatives regarded by means of Canadian courts.
Part II units out the theoretical underpinnings of the fiduciary idea of the nation.
Part III explores the results of the fiduciary conception for administrative legislation and customary legislations constitutionalism, and within the ultimate bankruptcy situates the idea inside of a broader philosophical dialogue of the rule of thumb of legislations.

There is a simple differential analog of this example. Suppose we require that the solution to y' + (cot x)y = -1 be finite at x = O. The general solution to this equation is y(x) = (cos x + K)/sin x. The condition that y(O) be finite requires that K = -1 and uniquely determines the solution. n Nonlinear difference equations are usually harder to solve than nonlinear differential equations. However, here are some examples that can be solved in closed form. Example 6 an+1 = a;. To solve this equation we take the logarithm of both sides: In an+I = 2 In an' The solution to this equation is easy to find because it is a linear equation for In an' The solution is In an = 2n - 1 In a l .

Equidimensional-in-x Equations An equation is said to be equidimensional in x if the scale change x -+ ax leaves the equation unchanged. The following equations are equidimensional in x: y" + 17y'/x + 101y/x 2 = 0, y" = yy'/x, y" = Y"'Y'X2. All equations which are equidimensional in x can be transformed into autonomous equations of the same order. 2c) and so on. Example 2 Conversion of an equidimensional-in-x equation to an autonomous equation.
1) where a(x) and b(x) are arbitrary functions of x and P is any number. This equation has two elementary cases: when P = 0 the equation is linear and when P = 1 the equation is separable. 3 ) is soluble because it is linear in u(x). Example 1 Bernoulli equation. The differential equation y'(x) = x/(x 2y2 + l) is not a Bernoulli equation in y. However, exchanging the dependent and independent variables gives (d/dy)x(y) = xy2 + l/x which is a Bernoulli equation in x (P = -1). The solution is x(y) = ±(ete2y3/3 - tl- i)t/2.

This might have got reviewed in dance music magazines, but as of now there's no way of knowing, and once you strip out the sources from the artist's social media and record company, all that's left are three fake Grrammy nominations, a primary source interview in a non-RS publicising the album, and a "review" in another source of dubious quality (the author is a freelance blogger and musician) which is less of a review and more an introduction to the website hosting a stream of the album.

MSE hosting MSMQ's
Jul 9, 2009 at 4:44 PM
I saw this thread (http://servicesengine.codeplex.com/Thread/View.aspx?ThreadId=35814) and was wondering if anyone could elaborate on setting up an MSE endpoint that delivers requests to a queue. For some reason my head keeps getting flipped around when I try to visualize this and what the configuration might look like. I keep thinking I need the queue defined on the left side (the published WCF service) and don't see how I would define a queue on the right side (the backend system/service) which I think of as the thing I'm virtualizing.
I would very much like to create a service in MSE that delivers to a queue. We would like biztalk to process the messages that arrive in that queue.

If you create a WCF Service that uses the netMsmqBinding you can import it into the MSE using the Web Service Metadata wizard (Tools -> Load Resources ->Web Service Metadata). Since the MSMQ implementation will be a one-way call, you'll notice the loaded resources and corresponding virutal operations won't have response contracts. On the "left-side" you can host the operation over a basic http binding for example.
You can also host the queued endpoint in the MSE if you want (which would mean the client is actually sending messages to a queue rather than directly to the MSE). In this scenario the MSE Endpoint would use netMsmqBinding and the Endpoint Path field would represent the queue name (i.e. private/msehostq). When the MSE Runtime is running, it would pull items from the queue and deliver them to whatever implementation is defined by the corresponding Resource definition (which could also be a queue).

Jowett Walk
Jowett Walk is a road in central Oxford, England. It connects Mansfield Road to the west with St Cross Road to the east, running parallel with and north of Holywell Street.
The road was formerly named Love Lane and used to continue north to South Parks Road on what is now Mansfield Road. It is now named after the well-known Victorian Master of Balliol College, Benjamin Jowett (1817–1893). Much of the land in the area is owned by Balliol College, including the playing fields to the north and student housing. The Michael Pilch Studio, owned by Balliol College, is a black box theatre located in Jowett Walk.
Merton College has a graduate annexe to the south of Jowett Walk at the eastern end. The Oxford Department of International Development is on the corner with Mansfield Road. | WIKI |
ordeal, ancient legal custom whereby an accused person was required to perform a test, the outcome of which decided the person's guilt or innocence. By an ordeal, appeal was made to divine authority to decide the guilt or innocence of one accused of a crime or to choose between disputants. This custom was known to ancient peoples as well as to those of fairly advanced material culture. Until recent times the ordeal was practiced in many parts of Asia and Africa. In the early Middle Ages it was widely used to settle legal questions in Western Europe. In England it was a regular form of trial and persisted until trial by jury became common. Forms of the ordeal varied with the locality and with the nature of the crime. The ordeal by fire—walking through fire or putting the hand into a flame—was common, and there were other fiery ordeals, such as walking on hot plowshares or plunging the hand into molten metal. Usually it was believed that if the accused were innocent God would spare him. Commonly there was a lapse of several days before the injuries were inspected; then someone considered a competent judge decided from the severity of the injuries as to innocence or guilt. One form of ordeal, the trial by water, was that used to determine whether or not an accused woman was a witch. The woman was bound and cast into water that had been blessed. If the water rejected her—i.e., if she floated—she was considered guilty. If the water received her, she was considered innocent. A common form of ordeal in contentions between two parties was the submission to some trial of chance, e.g., casting lots. Allied to this in spirit was the duel, which supposedly worked on the principle that God would favor the cause of the righteous in the battle. The trial by battle or by combat (sometimes called a judicial duel or wager of battle) was a recognized procedure in the Middle Ages. It was introduced from France to England after the Norman Conquest. In this trial, one of the contending parties issued a wager of battle, or challenge. Both parties under oath declared their assertions truthful; a duel was fought, and the victor was awarded the decision. In case one of the parties was a woman, a child, or a feeble man, he or she could be represented by a champion, i.e., a knight who was a relative or who had agreed to fight. As time went on a class of professional champions arose. The Roman Catholic Church from early times disapproved of the ordeal despite its apparently religious aspect, and in 1215 it categorically forbade the clergy to take part in such ceremonies.

What is Better than Morpheus8? A Comprehensive Guide
Deep Radio Frequency (RF) is a powerful technology that can provide superior results compared to Morpheus8. Learn more about this technology and how it compares to Morpheus8.
What is Better than Morpheus8? A Comprehensive Guide
When it comes to skin rejuvenation, there are many options available. But what is better than Morpheus8? Deep Radio Frequency (RF) is a powerful technology that can provide superior results compared to Morpheus8.It is four times more powerful and can penetrate deeper into the skin, allowing for optimal protein denaturation in a single treatment. The Morpheus8 RF microneedle is less powerful than Profound, but it can still deliver impressive results with minimal downtime or recovery period. After treatment, your skin may feel warm and red, but this usually subsides within 4 to 24 hours.
Morpheus8 follows a similar technique as Profound, but it uses radio frequency energy inside the device. This allows for deeper penetration into the subdermal tissue of up to 8 mm and the ability to target all three levels of skin tissue at once. This reduces treatment time and improves skin tone and texture.

It would appear that there are only 256 megs of ram available, and no swap. With that small amount of ram, you might have to allocate some disk to swap just so you can operate efficiently. This is done by building a file, say one gig bit, then tell the system to use it a swap.
You will use dd to build the file, mkswap to format it, and swapon to tell the OS to use it. In this example, "swampy" is the name of the file
dd if=/dev/zero of=/swampy bs=1024 count=1048576
mkswap /swampy
swapon /swampy
You'll want to add it to /etc/fstab so it will be used next time you reboot:
/swampy swap swap defaults 0 0
Once that is done, post back errors. | ESSENTIALAI-STEM |
RT Journal Article SR Electronic T1 Inhibition of Neuron-Restrictive Silencing Factor (REST/NRSF) Chromatin Binding Attenuates Epileptogenesis JF eneuro JO eNeuro FD Society for Neuroscience SP ENEURO.0006-24.2024 DO 10.1523/ENEURO.0006-24.2024 VO 11 IS 5 A1 Hall, Alicia M. A1 Kamei, Noriko A1 Shao, Manlin A1 Mun, Hyun-Seung A1 Chen, Kevin A1 Chen, Yuncai A1 Baram, Tallie Z. YR 2024 UL http://www.eneuro.org/content/11/5/ENEURO.0006-24.2024.abstract AB The mechanisms by which brain insults lead to subsequent epilepsy remain unclear. Insults including trauma, stroke, infections, and long seizures (status epilepticus, SE) increase the nuclear expression and chromatin binding of the neuron-restrictive silencing factor/RE-1 silencing transcription factor (NRSF/REST). REST/NRSF orchestrates major disruption of the expression of key neuronal genes, including ion channels and neurotransmitter receptors, potentially contributing to epileptogenesis. Accordingly, transient interference with REST/NRSF chromatin binding after an epilepsy-provoking SE suppressed spontaneous seizures for the 12 d duration of a prior study. However, whether the onset of epileptogenesis was suppressed or only delayed has remained unresolved. The current experiments determined if transient interference with REST/NRSF chromatin binding prevented epileptogenesis enduringly or, alternatively, slowed epilepsy onset. Epileptogenesis was elicited in adult male rats via systemic kainic acid-induced SE (KA-SE). We then determined if decoy, NRSF-binding–motif oligodeoxynucleotides (NRSE-ODNs), given twice following KA-SE (1) prevented REST/NRSF binding to chromatin, using chromatin immunoprecipitation, or (2) prevented the onset of spontaneous seizures, measured with chronic digital video-electroencephalogram. Blocking NRSF function transiently after KA-SE significantly lengthened the latent period to a first spontaneous seizure. Whereas this intervention did not influence the duration and severity of spontaneous seizures, total seizure number and seizure burden were lower in the NRSE-ODN compared with scrambled-ODN cohorts. Transient interference with REST/NRSF function after KA-SE delays and moderately attenuates insult-related hippocampal epilepsy, but does not abolish it. Thus, the anticonvulsant and antiepileptogenic actions of NRSF are but one of the multifactorial mechanisms generating epilepsy in the adult brain. | ESSENTIALAI-STEM |
Ein Danklied sei dem Herrn
"Ein Danklied sei dem Herrn" (A song of thanks be to the Lord) is a Christian hymn with German text written by Guido Maria Dreves in 1886, and a melody written by Josef Venantius von Wöss in 1928. It is a song of thanks and praise of God who protects the people he created. The song appeared as part of the Catholic Gotteslob.
Background and history
Guido Maria Dreves was a Jesuit who researched the history of Latin hymns and published bibliographies of them in several volumes. He also wrote the text of hymns, including "Ein Danklied sei dem Herrn" in seven stanzas in 1886.
Josef Venantius von Wöss was an Austrian composer, teacher and lector based in Vienna who supported the Cecilian Movement. He composed the melody and a four-part setting. Five of the stanzas were included in the common Catholic German hymnal Gotteslob as GL 382. The hymn is also part of other songbooks.
Theme and text
The text was originally in seven stanzas of seven lines each, rhyming ABABCDD. The song expresses thanks to God. In the first stanza, the focus is on his unlimited ("ganz ohne Maß") goodwill ("Huld") and merciful patience ("allbarmherzige Geduld"). In the second stanza, the singer talks to his soul, requesting to praise God day and night, as in some psalms, such as Psalm 103. The third stanza deals with God as the Creator. The fourth stanza reasons that all sorrows can be dismissed knowing that God knows a person's name, written in his hand. The final line repeats to trust in God's protection, being sure that he has good intentions for every person ("und sei gewiss, er meint es gut.)
Melody and music
The melody is in C major and common time. It uses the range of an octave, and reminds of an anthem in a festive mood. Text and music of the last three lines of each stanza are repeated.
Usage
The hymn is used when thanks to God are expressed, such as in a service giving thanks to Pope Benedict XVI at the Würzburg Cathedral on 28 February 2013, the day that his resignation took effect. | WIKI |
The Teacher from Vigevano
Il maestro di Vigevano, English title The Teacher from Vigevano, is a 1963 Italian comedy drama film directed by Elio Petri. It is based on the novel of the same name by Lucio Mastronardi.
Plot
Antonio Mombelli is a primary school teacher, married and father of a son. Although he is satisfied with his humble life and salary, his ambitious wife Ada pushes him to quit his job and open a small shoe factory with his severance pay. After his business' bankruptcy due to a tax investigation, Antonio takes a new exam to return to his teacher's job, but is devasteated to learn that Ada betrays him with local industrialist Bugatti.
Reception
The critical reception of The Teacher from Vigevano was mixed. Gianni Rondolino acknowledged Petri's portrayal of the locale, but criticised the film for repeatedly giving in to "the needs of mass entertainment" and "broad and simple tastes". | WIKI |
Polystichum luctuosum
Polystichum luctuosum is a species of fern known by the common names Korean rock fern and Tsushima holly fern. It is a small, clump-forming, tufted, evergreen to semi-evergreen fern native to Japan, Korea, Taiwan, China, Vietnam, and Thailand, as well as southern Africa. The fern grows to about 1–1.5 feet in height, with a spread of 1–1.5 feet, with stipe up to 30 cm long, pale to mid-brown, with dark brown to almost black scales, and bi-pinnate, glossy, dark green fronds.

Policy-Based-Routing (pbr) package discussion
The old vpn-policy-routing thread grew too big and contains a lot of outdated information, now that pbr is available, so I've decided to start a new thread.
pbr is a next generation service supporting split-tunneling for multiple types of VPN tunnels (Openconnect, OpenVPN, PPTP and Wireguard), allowing you to create policies to use a designated VPN tunnel or WAN as a gateway. More information (requirements, full features list, etc.) on the service is available in the README.
Differences between pbr and vpn-policy-routing

With update to version pbr 0.9.9-1, the new luci-app-pbr 0.9.9-1 is required!
If you're using pbr on an x86_64 system, you can install the dnsmasq 2.87 from this post and test the pbr in the nft mode.

The WebUI app (luci-app-pbr) version 0.9.9-3 has been converted to javascript.
Here's the current list of TODOs for the new luci app, so don't report these issues:
1. Gateways are not shown at the top.
2. If there were any errors during pbr last run, they are not shown at the top.
3. Same goes for any warnings.
4. The option to select resolver set support for domains is missing descriptions for options which are unavailable on the platform.

Made some progress in WebUI development in 0.9.9-4. The current issues are:
• WebUI is not refreshed after button click. I hope to address it in the near future.
• The option to select resolver set support for domains is missing descriptions for options which are unavailable on the platform.
Both pbr and luci-app-pbr have to be updated together for 0.9.9-4.

Some news for 0.9.9-5 (I bet you can tell I'm getting ready to send PR for version 1.0.0 ;)):
• Implemented (hopefully, don't have the time to set up the test and there's not much interest from other users, but I didn't want my efforts to support it with iptables to go to waste) TOR support in nft. That achieves the feature parity in the iptables and nft supporting versions.
• More progress on WebUI, the initial load may take longer due to 3 RPCD calls, but then the page renders with all the information at hand.
The only issue currently is:
• WebUI is not refreshed after button click. I hope to address it in the near future.

Uppercase in any interfaces is making the last few builds not function properly.
The dropdowns in the luci app forces them to lowercase. The interfaces have some uppercase letters so pbr cannot find the interface because of the case.
I wish I could paste more but I have no laptop only on my phone.
I have to edit the pbr config manually to properly set the case.
Fixed in 0.9.9-6.

they're all coming up as undefined now
all my tunnel interfaces are named like this
tun1_NordVPN
tun2_NordVPN
etc
they were coming up fine on my end, unless the package was only partially updated I don't see how it could happen. I've bumped the version to 0.9.9-7 just in case, run opkg update on both packages.
Same problem here, when making a rule, al options are ' undefined'
Existing rules are fine, only happens on a new rule.
version 0.9.9-8
When I make the config in cli, it's fine. Shows ok in luci also after refresh.
opkg install --force-reinstall pbr luci-app-pbr didn't help
Changing an interface on an existing rule are all undefined too.
0.9.9-8 is okay now .. they all display correctly
Did a opkg remove --force-remove luci-app-pbr pbr
Reboot
opkg update
opkg install pbr luci-app-pbr
No luck, still only option (on Luci) is "undefined'
Sadly, I can't reproduce to try to figure it out.
I feel it's RPCD not picking up the changes. I believe I've read that sometimes it's needed to restart (not reload) RPCD when installing/updating RPCD scripts, however RPCD restart will log you out of WebUI, which is bad user experience when installing packages from WebUI.
Please try running from shell:
rm -rf /var/luci-modulecache/; rm -f /var/luci-indexcache;
[ -x /etc/init.d/rpcd ] && /etc/init.d/rpcd restart;
And/or rebooting your router.
PS. Oh, the old webui javascript may be cached in your browser!!! If using chrome, open dev tools and in the dev tools settings, check "Disable cache (while DevTools is open)". Or open a new incognito window in whatever browser you use.
I'd appreciate more testing/feedback on the nft support in the pbr. I have a handful of policies, so would like larger testing. @d3adc0d3 already spotted a bug which will be fixed in upcoming 0.9.9-9.
Did run;
rm -rf /var/luci-modulecache/; rm -f /var/luci-indexcache;
[ -x /etc/init.d/rpcd ] && /etc/init.d/rpcd restart;
After disable cache (and in a incognito window) it works again. So a cache refresh problem I gues.
Yeah, I'm thinking it's more of a browser cache problem than anything else. I see why it's enabled for WebUI by default, but I don't understand why have a new file on the router doesn't trigger cache refresh.

I see in the scenario 2 wireguard example for PBR/vpn-policy-routing there are 2 interfaces, wg-server and wg-client. I am a bit confused why this is done. Can you explain a bit more about why this is necessary vs simply adding an interface with Protocol: WireGuard VPN as per docs?
You run the wg "client" on your router if you want traffic originating from your router to be encrypted/go thru the VPN tunnel.
You run the wg "server" on your router, if you want to be able to connect to your home network while away from home.
A lot of people have both and those are the scenarios where headaches occur, hence the examples.
PS. In reality, everything in wg is peers, there's no client or server, but it's way easier to use those definitions to express the intent of the peer.

What is the best definition for refract?
Refract is defined as to cause sound, light or heat to bounce back in a straight line. (optics) To cause (light) to change direction as a result of entering a different medium. A prism can refract light. verb. To alter by viewing through a medium.
What is refract in a sentence?
Refract sentence example The clouds contain ice crystals which refract the light to give the halo effect. The simplest way of showing dispersion is to refract a narrow beam of sunlight through a prism of glass or prismatic vessel =containing water or other clear liquid.
What is the simple definition of refraction?
refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in deep water than in shallow.
What causes refraction?
Refraction is caused by the wave’s change of speed. Refraction occurs with any kind of wave. For example, water waves moving across deep water travel faster than those moving across shallow water. A light ray that passes through a glass prism is refracted or bent.
What is the difference between reflection and refraction?
Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.
How do you explain refraction to a child?

How do you use refracting in a sentence?
The distinctive blue color of the water is caused by minute clay particles suspended in the water refracting the sunlight. This is the hot and cold air refracting the light waves above the hot tarmac.
What are 5 examples of refraction?
Give 5 examples of refraction of light in daily life
• Twinkling of stars in a clear sky.
• Pool of water appears to be less deep than what it actually is.
• Rainbow formation in the sky.
• Camera lenses.
• Glasses.
How are rainbows formed?
A rainbow is a multicolored arc made by light striking water droplets. The most familiar type rainbow is produced when sunlight strikes raindrops in front of a viewer at a precise angle (42 degrees). Light entering a water droplet is refracted. It is then reflected by the back of the droplet.
How is a wave refracted?
Waves change speed when they pass across the boundary between two different substances, such as light waves refracting when they pass from air to glass. This causes them to change direction and this effect is called refraction. Water waves refract when they travel from deep water to shallow water (or vice versa).
How do you bend a light?

What can Prism do?
prism, in optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colours, called a spectrum.

2009 Clipsal 500
The 2009 Clipsal 500 was the first race of the 2009 V8 Supercar Championship Series. It was held on the weekend of 20–22 March around the inner city streets of Adelaide, the capital of South Australia.
Qualifying
Qualifying was held on Friday 20 March, and was split into two sessions. Session one lasted for 34 minutes, 15 seconds and saw the top ten drivers qualifying for the Top Ten Shootout, with positions 11–30 being set by times in the session. In this first session, reigning series champion Jamie Whincup set the pace, setting a new qualifying lap record of 1:21.2773. Although he was some half a second slower in the Shootout, Whincup was still quick enough to lead a Triple Eight Race Engineering 1–2 with Craig Lowndes 0.2545 seconds behind. Mark Winterbottom and Lee Holdsworth had both gone faster than Lowndes but both drivers lost their respective times due to excessive use of kerbing during their hot laps. Garth Tander was top Holden in third, with James Courtney qualifying fourth, in his first session as a Dick Johnson Racing driver.
Race 1
Race 1 was held on Saturday 21 March.
Race 2
Race 2 was held on Sunday 22 March.

I have a twig date field template that has a mysterious extra blank space that I want to remove.
In my twig template, field--comerce-product--field-ppromotion-enddate.html.twig, I have the following line:
<div{{ item.attributes.addClass('field--item') }}><span class="green">{{ item.content }}{{ 'TEXT'|trans }}</span></div>
Unfortunately, the printed output looks like this:
2017-12-25 TEXT
I don't know where the space is coming from.
I am using a similar template for an integer field that has this line:
<div{{ item.attributes.addClass('field--item') }}><span class="discount">{{ item.content }}{{ 'OFF!'|trans }}</span></div>
This prints the discount percentage (integer field) and then the word "off" (example: 20%off)-- there is no space between the percentage and off, which is what I want.
(Why no space? My site actually uses an Asian language that doesn't use spaces.)
So where is this space coming from on the date field? When the date field content is printed, it uses the template time.html.twig, but the content of that template is this single line (skipping the comments):
<time{{ attributes }}>{{ text }}</time>
EDIT: Based on the suggested answers, I have tried {{- foo -}} to remove the whitespace around the date and text, as well as {%spaceless%} to remove other whitespace, but the extra space is still there between the date and the text):
{% spaceless %}
<div{{ item.attributes.addClass('field--item') }}><span class="green">{{- item.content -}}{{- 'TEXT'|trans -}}</span></div>
{% endspaceless %}
Actual output of this code: 2017年12月25日 TEXT
Output should be: 2017年12月25日TEXT

Nonlinear perturbations of AdS spacetime
October 9, 2017
3:00pm to 4:15pm
IFT Seminar Room/Red Room
Theoretical Physics, general interest
Speaker:
Oleg Evnin
Institution:
Chulalongkorn University (Thailand)
Location&Place:
IFT Seminar Room/Red Room
Abstract:
I will start with a bit of general review of the AdS stability program exploring the elaborate nonlinear dynamics of small perturbations in Anti-de Sitter spacetime. The main mathematical tool for these investigations is nonlinear perturbation theory based on application of the time-averaging method. I will then focus on a specific simple realization of this setup (conformally coupled self-interacting probe scalar in AdS), for which the resulting effective time-averaged dynamics displays remarkable features connecting to the "cubic Szegő equation" (actively studied in the current math literature) and suggestive of integrability. I'll also mention connections to weakly nonlinear dynamics of trapped Bose-Einstein condensates. | ESSENTIALAI-STEM |
Mosh (model)
Mosh (born August 21, 1989 in Russia) is a Russian-American alternative model and burlesque performer. Called "one of the world's leading alternative and fetish models" by ModelMayhem.com, she has been on the cover of Bizarre magazine a near-record seven times, as well as LA Weekly, OC Weekly, Girls and Corpses, DDI Mag, and numerous others. She has been featured on Playboy.com and Maxim en Espanol, and also stars in the music video for Pink's "Blow Me (One Last Kiss)." along with Nick 13's music videos for "Nighttime Sky" and "In the Orchard" from his eponymous album. More recently, she appears in the Smashing Pumpkins video "Silvery Sometimes (Ghosts)".
Background
Mosh was born in what was then the Soviet Union, but moved to the United States with her family at the age of three. She trained in gymnastics for more than 10 years in school and was a cheerleader in high school, but injured her elbow in her first year as an acrobat. This limited her movement, and soon she began developing an interest in fetishwear, bondage, and pinup photography, ultimately guiding her to alternative and fetish modeling and burlesque.
Career
Mosh began building her modeling portfolio at the age of 17, networking on Modelmayhem.com to set up photo shoots with local photographers while juggling high school, a job and an internship. She learned how to do her own styling and makeup, partially out of necessity due to an inability to pay makeup artists, which led to the development of her self-styled signature look. After some years of modeling, Mosh began to combine her tease and fetish aesthetics with her gymnastic experience from her childhood, becoming a burlesque and fetish performer.
Her fetishes include latex, corsets, stockings, ropes, and more. She operated an exclusive pay-based website for her fans, which offers members-only photos, videos, and information. | WIKI |

Birds of My Neighborhood
Birds of My Neighborhood is the fourth studio album by the Innocence Mission. Released in 1999 on Kneeling Elephant, a sub-label of RCA, the album was out of print until Badman Recording acquired the license to remaster and reissue it in 2006.
This was the group's first album as a trio following the departure of founding member Steve Brown in 1997. With the exception of his sole contribution to the album—drums and brushes on "Snow"—the album is largely bereft of drums. Don Peris played percussion on "Birdless" and the closing moments of "Green Grass, Red Tree," but otherwise the group adapted to its trio status by replacing Mike Bitt's electric bass with an upright bass and taking a more acoustic sound.
Their cover of "Follow Me" was recorded in late 1997 for Take Me Home, a John Denver tribute album which had an estimated release date of 1998. With the delay of that album's release, however, Don Peris asked that record's curator, Mark Kozelek of the Red House Painters, for permission to include the song on Birds of My Neighborhood. Kozelek agreed on the condition that the song still be included on the tribute album when a general release was finally given in April 2000.
Sufjan Stevens recorded a cover version of "The Lakes of Canada" in 2007.
On February 5, 2021, a vinyl reissue was released, which came with an updated album cover.

Go vs Javascript. What to write IoT projects
Which programming language is better for your IoT project? The answer to this question is ambiguous and subjective. There are several aspects to consider when considering this issue: objectives, goals and needs of your project. An important role is also played by your personal preferences, availability and capabilities of qualified developers.
There is an opinion that Golang , developed by Google , may ultimately force JavaScript (or, better, Node.js) out of the realm of IoT applications. Is a gopher true to win this battle? Let's take a closer look at both Golang and JS, their advantages and disadvantages for IoT solutions.
Javascript
Programming languages come and go, but it seems that JavaScript will remain for a long time. Originally hated by developers, today this top programming language is widely used on the Internet of Things because of its high resource efficiency. Since the topic of using JavaScript in IoT applications is quite extensive and can include frontend, backend and other development stages, let's narrow it down to Node.js. As you know, JavaScript is a language, and Node.js is a software platform. It allows you to establish flexible interaction with input-output devices through its API, as well as connect the necessary library for solving problems.
Node.js is ideal for managing networks of sensors, radar, beacons, microsystems, and other connected devices. In addition, it does an excellent job of handling several tasks to maintain the interaction between all these IoT devices. The developers agree that the advantages of Node.js for software IoT software are ease of use and reasonable memory requirements.
Leading IoT companies, such as Telefonica, Rightech and Salesforce IoT Cloud, continue to implement Node.js in their projects, so the demand for JavaScript developers in the near future does not seem to fall.
Golang
Go is an open source programming language. It is not yet as widely distributed as JavaScript, but it has already managed to capture its own piece of IoT pie. Like most platforms and programming languages, it has resulted from developer dissatisfaction with existing solutions. Go was created to speed up the introduction of new developers into the workflow, so one of its main features is ease of development, use and reading, that is, a low entry threshold for anyone who wants to start developing in an unfamiliar language. This language has a relatively narrow set of functions, although it benefits in parallelism and performance.
Also, its features include:
• Strong typing, data types are set at the compilation stage, therefore, their inconsistency can be traced before launch;
• Since the language is stricter in it less bulky structures and, accordingly, it is easier to read;
• This language is actively used in the development of infrastructure software like Docker, Kubernetes, etc. Knowledge of Go, if necessary, will allow you to further explore these tools;
• The ecosystem of the language is relatively young, then there is an opportunity to contact technical support for language developers to solve problem issues;
Programmers typically choose Golang to build a communication layer in the IoT system, since parallelism and the ability to simultaneously launch data input / output are among the key benefits of Go. Also this language is great for writing logging and parsing services.
Other not so obvious benefits of Go include:
• tools: documentation - GoDoc and code analysis - Race Detector;
• built-in testing tool (if you have ever tried to choose a framework for testing a project in JavaScript, you understand the benefits);
• serious approach to parallel programming with Data Race Detector ;
• a unified style guide for everyone that needs to be followed, in contrast to the multitude of tools and paradigms in JavaScript (they are known to paralyze a team when it is time to decide on structure, conventions, testing libraries, etc.)
Compare by individual criteria:
Both JavaScript and Go seem well suited for IoT projects. Therefore, let's compare the functionality of Node.js and Go to determine the winner.
Maturity. Being relatively young, Go is a rather mature language, besides, it was initially positioned as stable and backward compatible. As for Node.js, it has a version of LTS (Long Time Support, long-term support), as well as the latest version, which has a changing API, and an extensive community that supports the platform.
Performance. . In real-world conditions, network interactions and interactions with the Go and Node.js database show equal results.
Parallelism.Here Go definitely wins: it uses light threads - goroutines, and Node.js inherits the JavaScript event-handling mechanism, which has its drawbacks.
Learning curve. Thanks to JavaScript, according to a recent survey, Node.js has become one of the fastest growing development languages. The reason for this is simple learning, extensive documentation and a large open community. Go is also quite easy to learn. The PW Engine survey showed that most developers consider it very intuitive, and this is a big plus if the company needs to introduce new employees into the work process as soon as possible. So, here is a draw too.
Error processing.Here opinions differ. Go uses explicit error checking, as opposed to the implicit try \ catch. Due to this, error checks become larger, but they are clearer, since they are closer to the place of their occurrence and are aimed at identifying problems in a particular place, in the second version of Go they promise to add check \ handle. Node.js uses the try \ catch principle, which is common to many languages and has certain limitations.
Frontend and backend.Go is aimed at developing parallel services, so it is great for the server side. And although Go has frameworks for building web applications such as Beego and gopherjs, it’s much more convenient to create a modern user interface with JavaScript. In addition, based on the fact that JS dominates at the frontend, it is easier to maintain both the backend and the frontend in the same language - JavaScript
The choice of developers. There is no doubt: JavaScript remains at the top because it has long been incorporated into the workflow of developers around the world. Of course, Go entered the top 20 most popular technologies, but, unfortunately, it is still far from JavaScript in terms of popularity.
Sync / Async IO (synchronous / asynchronous I / O).Node.js is famous for its non-blocking I / O model, which makes it easy and efficient in terms of resources. But it also has flaws, such as endless callbacks in the code and strange stack traces. On the other hand, Go, using its scheduler, recommends that developers use synchronous operations, relying on various tools provided by the OS, to increase efficiency and reduce blocking resources.
Work on devices. With the package manager, NPM Node.js can be effectively used as a programming environment on single-board games, such as Raspberry Pi, Iskra Js or BeagleBone Black . NPM contains about 80 open source packages for Arduino, Intel IoT Edison controllers, Raspberry Pi and more than 30 packages for various devices and Bluetooth sensors. As for Go, it fits well with the Raspberry Pi boards, as it launches the complete Linux build. However, low-power IoT devices, such as Arduino, cannot work with the Go binary code. That is why the Gobot framework was created. It supports multiple platforms, Bluetooth LE devices and even the NeuroSky interface.
Libraries. By the number of JavaScript libraries, of course, he still bypasses his opponent, but in certain areas, for example, in mathematics, Go has written more powerful tools for working with complex mathematics and data analysis.
Conclusion
Golang is a compiled multi-threaded programming language that allows you to create entire systems of connected controllers, and work efficiently with databases. JavaScript is ideal for asynchronous operations that require low response times. Now these two languages are far from interchangeable. JavaScript remains the most popular language in the world, including specifically on the Internet of things. He firmly holds his position and is unlikely to give way to Golang in the near future. However, thanks to its innovative and robust approach, Go has very bright prospects to lead the top IoT development technologies.

Maria Beig
Maria Beig (8 October 1920 – 3 September 2018) was a German school teacher and author.
Life and career
Beig was born on 8 October 1920 near Lake Constance in the German region of Swabia.
Beig published her first novel, Rabenkrächzen (Raven's Croak) in 1982. It followed the fictional lives of four families from Meckenbeuren. While it was unpopular in her home region of Swabia, it did win the Alemannischer Literaturpreis in 1983.
Her second novel Hochzeitlose (Lost Weddings) was published in 1983 and follows four women from Swabia during the World War I and II. It is set out as four novellas, each focusing on a different woman; Babette, Helene, Klara and Martha, and their refusal to marry. It was translated into English by Jaimy Gordon and Peter Blickle.
Her novel, Hermine: An Animal Life, centers around a fictional woman and her interactions with 64 species of animal on her family's farm. It was also translated by Gordon and Blickle.
In 1996, she won the Johann-Friedrich-von-Cotta-Literatur- und Übersetzerpreis der Landeshauptstadt Stuttgart award and was awarded with the Johann-Peter-Hebel-Preis in 2004.
Her success as a writer was in part aided by the encouraging support she received from the German novelist Martin Walser who directed her to publish with Suhrkamp, a major publisher in Germany. In 2009 she published her autobiography called Ein Lebensweg. | WIKI |

Transforming JSON Data into an API with Serverless
Transforming JSON Data into an API with Serverless
This is something that has been sitting in my “To Write” Trello board for a while now and today I finally got around to building a demo. One of my favorite things to do with serverless is to build API wrappers. There are thousands of APIs out there, but many times you need to manipulate or change the data to make it more appropriate for your use. While you can do that on the client, it can be much more efficient to do so on the server. Of course, who wants to setup a server just to change an API when you can use a serverless function instead? Some examples of this are:
• Transformation: A few months back I used an API that was XML only. I used a severless function to transform it into JSON since this isn’t 1995.
• Reduction: A while ago I made use of a music API that returned a lot of information. However, I only needed one small part of it. By building a serverless proxy that reduced the data returned, my client, a mobile app, received much less data and therefore was quicker for the end user.
• Combination: If one API doesn’t cover what you need, two or more may, and you can use a serverless function to grab and combine those APIs. A good example of this is getting shipping information from multiple providers.
• Proxy: And finally - just having your own end point means you can do things like server-side caching or even wholesale replacement of the ‘real’ API at any time in the future.
For my demo today, I’m doing something interesting I think. Sometimes an API isn’t really an API, but just a data dump. It may update every now and then, but it doesn’t support arguments. It’s simply a URL that returns JSON. I thought it would be cool to show how you can build your own API in front of that JSON dump. I’ll be using Webtask.io but obviously any serverless provider will do.
For my data, I’m using a JSON packet of Pokemon data here: https://raw.githubusercontent.com/Biuni/PokemonGO-Pokedex/master/pokedex.json. I found this dataset via jdorfman’s awesome-json-datasets repo. The JSON data contains 151 different Pokemon. I have no idea how accurate that is. I’ve got kids who do but they aren’t around me and I don’t care enough to Google for it. ;)
For the first draft of my function, I simply returned the data. I also used a cache. As you know (or may know!), serverless is stateless. However, most serverless providers will keep your function “warm” (think active) for a short duration. That means repeated calls within a certain timeframe can make use of locally cached values for quicker results.
const JSON_URL = 'https://raw.githubusercontent.com/Biuni/PokemonGO-Pokedex/master/pokedex.json';
let rp = require('request-promise');
let cached;
module.exports = async (context, cb) => {
let data = await getData();
cb(null, { data });
};
async function getData() {
if(cached) {
console.log('using cache');
return cached;
}
else {
return new Promise((resolve, reject) => {
rp(JSON_URL)
.then(res => {
cached = JSON.parse(res).pokemon;
resolve(cached);
});
});
}
}
That’s a fairly simple function. Basically return a cache or hit a URL and return that. No transformation, manipulation, or anything else. Again though I have some immediate benefits. If the server hosting the data is a bit slow, my cache can help with that. If the URL ever goes away, or if they decide to start charging for the data, I can potentially switch to another provider and my client’s will never know. (And if the data changed, then I can change it back!)
Alright - now let’s add some filtering!
const JSON_URL = 'https://raw.githubusercontent.com/Biuni/PokemonGO-Pokedex/master/pokedex.json';
let rp = require('request-promise');
let cached;
module.exports = async (context, cb) => {
let data = await getData();
// support filter by name
if(context.query.name) {
console.log('filter to name '+context.query.name);
let sname = context.query.name.toLowerCase();
data = data.filter(p => {
let lname = p.name.toLowerCase();
return lname.indexOf(sname) >= 0;
});
}
// support filter by type
if(context.query.type) {
let type = context.query.type.toLowerCase();
console.log('filtering to type '+type);
data = data.filter(p => {
//rewrite types to lowercase
let types = p.type.join(',').toLowerCase().split(',');
return types.indexOf(type) >= 0;
});
}
cb(null, { data });
};
async function getData() {
if(cached) {
console.log('using cache');
return cached;
}
else {
return new Promise((resolve, reject) => {
rp(JSON_URL)
.then(res => {
cached = JSON.parse(res).pokemon;
resolve(cached);
});
});
}
}
I’ve added 2 possible filters here using the query string. (This is done via the Context object that all Webtasks have access to.) In both cases, I just do simple array based filtering. The only real “work” here is to lowercase stuff so you don’t have to worry about matching the same case. My core API may be found here:
https://wt-c2bde7d7dfc8623f121b0eb5a7102930-0.sandbox.auth0-extend.com/eoApi
And you can search by name, or type, or both. For example:
https://wt-c2bde7d7dfc8623f121b0eb5a7102930-0.sandbox.auth0-extend.com/eoApi?name=Ba
Or:
https://wt-c2bde7d7dfc8623f121b0eb5a7102930-0.sandbox.auth0-extend.com/eoApi?type=ghost
Or:
https://wt-c2bde7d7dfc8623f121b0eb5a7102930-0.sandbox.auth0-extend.com/eoApi?type=fire&name=ca
That’s it. Let me know if you have any questions by leaving me a comment below.

When Ruby Bridges was six years old and in the first grade, just like many other children, she went to a new school. Ruby's school was called William Frantz Elementary School. It was in the City of New Orleans in the state of Louisiana.
And, just like other children, Ruby was nervous about the first day of school. She knew everything was going to be different: a new building, new teachers, new rules, new things to learn, new children to play with, and (she hoped) new friends.
But, unlike other children, Ruby didn't go to school by walking or riding in her parents' car or in a school bus. Ruby went to school in a police car, followed by people from her neighborhood to help keep her safe. Ruby walked to the front door of her school surrounded by four tall men who had guns and wore armbands with the words "U.S. Marshal" on their sleeves.
Because Ruby wasn't just like the other children at William Frantz Elementary School. She was the only African American child in the entire school, and some people didn't think she should be there.
You see, Ruby started first grade in 1960, about sixty years ago. Back then, in some parts of the United States, children with different skin colors went to different schools. There were schools for children with dark skin, and there with schools for children with light skin. That was called segregation.
Some people liked segregation, but many people knew it wasn't fair. The schools for white children always had more books, better buildings, and lots more of everything than the schools for black children. Because of that, our government made a law that said all children—no matter what their skin color—can go to the same schools. That is called integration.
The parents at William Frantz Elementary School who liked segregation did not like integration. Because Ruby had dark skin, they thought she didn't belong at the school. They kept their children home from school, away from her. Ruby was the only student in her class. She didn't have anyone to play with or to talk to, except for her teacher, all day long.
And every day, those people who didn't like integration would go to Ruby's school, and they would yell horrible, mean things at her. Some called her names. One woman threatened to poison her. Sometimes they would even throw rocks or eggs or tomatoes, trying to keep her away from the school.
Yet every day, Ruby Bridges would go to that school. She would get dressed and eat breakfast and get ready for school, and then her mother would say, "I'm proud of you," and her father would say, "You're my brave little girl," and they would all say, "I love you" to each other.
Every day, her neighbors would surround the police car that Ruby was riding in, and the four U.S. Marshals would surround her as she walked through that crowd of angry people, to help keep her safe.
And every day, Ruby would say a prayer—but not for herself. Ruby prayed for the angry people who yelled at her, asking God to forgive them and to change their minds. When Ruby Bridges was surrounded by hate, she surrounded everyone with love.
After a while, it worked.
The next year, when Ruby Bridges was seven years old and starting the second grade, the angry crowd of people wasn't ther. She didn't have to ride in a police car. There were no U.S. Marshals surrounding her. White people did not keep their children home from William Frantz Elementary School, even though Ruby was there.
When Ruby went to her classroom on that first day of second grade, there were twenty other children. Some of them had dark skin, like her. Some of them would be her friends. Integration had happened, and William Frantz Elementary School was a school for all children.
Fifty years ago, Ruby Bridges helped to integrate a school, and integration helped make our country more fair for everyone. Today, Ruby Bridges is all grown-up, and she travels to schools all over the country, telling her story and teaching people to respect and appreciate each other.
Each of us can be like Ruby. We can all surround each other with love. | FINEWEB-EDU |
No future(s): Asian financial coal trading dries up as Noble declines, Glencore rules
SINGAPORE/FRANKFURT (Reuters) - Financial trading of thermal coal has virtually ceased in Asia as a result of the woes at one major trading house and the growing dominance of another, despite the region being by far the world’s biggest consumer of the fuel. Asia gobbles up some 70 percent of all coal used for power generation, and the unprecedented demise of its futures market poses significant risks for utilities in particular. With coal prices rising sharply this year, power generators would usually hedge or protect themselves by taking positions in related derivatives markets. “With Asia’s futures pretty much gone, that greatly increases our risk for supplies in that region. It may mean that we source less from there going forward,” said a risk manager with a big European utility, declining to be named as he was not authorized to speak publicly about company risk. Data from several exchanges shows that since its heyday in 2015, Asia coal futures trading activity has declined by over 90 percent. Two senior coal brokers and six senior traders at merchant houses, utilities and miners spoken to by Reuters pointed to the shrinking role of Singapore-listed commodity merchant Noble Group (NOBG.SI) as the single most important factor in the decline of Asian coal futures volumes. Noble has sold-off assets and slashed trading operations following allegations from Iceberg Research in 2015 that it had overstated its assets by billions of dollars, sending its share price tumbling. “Noble is a massive loss to the market. Its troubles seriously dented liquidity,” one merchant trader said. Noble declined to comment for this article, but said in a letter to Singapore Exchange in May “very thin trading liquidity” in hedging instruments had contributed to its first quarter losses. Many traders also see a link between declining Asian coal futures and the growing dominance of a single company in supplying physical Asian coal. Swiss-based, London-listed Glencore (GLEN.L) is the world’s biggest producer of thermal coal, exporting well over 50 million tonnes from Australia alone in 2016, a quarter of the country’s shipments. Physical Newcastle coal prices, which act as Asia’s key futures benchmark, have jumped from around $70 to over $100 per tonne this year. Glencore, which owns a dozen thermal coal mines in Australia, declined to comment. But market participants say the firm is not as active in coal futures trading as many of its peers, instead preferring bilateral supply deals with customers. “Doubts over deliberate intervention on the supply side for Australian coal linger, which kills any enthusiasm to trade the (financial) product,” said Georgi Slavov, head of research at commodity brokerage Marex Spectron. Glencore’s control and knowledge of actual coal output in Australia and the influence this has on derivatives contracts means it is difficult for outsiders to predict price movements, scaring off traders. “If you don’t know what Glencore’s mines are up to, it’s very hard to trade Australian coal futures,” said one trader with a large European utility. “It’s not Glencore’s wrongdoing, just the way it is.” Glencore has previously said it is as vulnerable as any other market participant to commodity price swings, and in the past has also used derivatives to hedge its own production. The decline in Asian coal futures volumes stands in stark contrast to booming oil and natural gas futures. The amount traded in front-month Australian coal futures on the Intercontinental Exchange (ICE.N) has collapsed from a high of over 1.6 million tonnes in September 2014 to under 290,000 tonnes this September. Data from rival CME Group (CME.O) shows that open interest, which describes the number of open positions, of its Asian coal futures as fallen from around 2.7 million tonnes in early 2015 to just 65,000 in August this year, with Indonesian and Chinese futures totally vanishing. “In that sort of environment, utilities stop hedging. It’s too risky,” said a senior coal trader with a major commodity merchant, requesting anonymity. Major European utilities that source international coal include Germany’s RWE (RWEG.DE), Uniper (UN01.DE) and ENBW (EBKG.DE), Italy’s ENEL (ENEI.MI), Sweden’s Vattenfall, as well as Switzerland’s Axpo Holding. “All coal derivatives markets have shrunken this year… as a result of lower options trading, and due to some counter parties that have become less active,” said Joachim Hall, cross commodity trader at RWE Supply & Trading, the trading arm of Germany’s biggest power supplier. “Europe’s API2 (coal futures market) remains liquid, but it does not move in parallel with physical coal we buy in Asia,” Hall said. Noble’s troubles and Glencore’s strength are not the only reasons for the malaise. Unlike many other markets, no single exchange has attracted enough liquidity to hedge reliably. Instead bourses like ICE, CME and others including China’s Zhengzhou Commodity Exchange (ZCE), Singapore Exchange (SGXL.SI) or the European Energy Exchange (T3PA.DE) offer contracts with varying delivery options, differing underlying coal qualities, and in various currencies. Chinese exchanges like ZCE <0#CZC> have grown somewhat, but months can still pass without trades, and Chinese coal futures are problematic for international traders. “There has been quite a bit of turmoil in the coal trading business,” said Ben Tait, analyst at British energy consultancy Prospex Research. “China is the driver. Its coal policy shifts can make prices soar or plunge. This has led to some big trading losses.” Yet not everybody sees only doom and gloom. RWE’s Hall said he hoped liquidity would gradually improve again over time, something Pat Markey, managing director of Singapore’s Sierra Vista Resources, also expected. “The Asian market is poised for growth in financial trading, but this will take time as the Asian market is quite fragmented,” Markey said.

NORD N.1200 NORECRIN
The Norécrin was developed to meet a French ministry of transport sponsored design competition. The Norécrin is a low-wing cantilever monoplane with a retractable tricycle landing gear and the prototype (Nord 1200) was designed to receive a nose-mounted 75 kW (100 hp) Mathis G4-R piston engine but flew only with a 100 kW (140 hp) Renault 4Pei (first flight on 15 December 1945 with Georges Detre as test pilot). The production version had three-seats and was designated the Nord 1201 Norécrin I. A number of variants were produced with different engines fitted. Later variants had four-seats and the Nord 1203 Norécrin V was a two-seat military variant with machine-guns and rockets. It was a successful design and 378 aircraft were built. | ESSENTIALAI-STEM |
FreeKB - IBM MQ (message queue) - Getting Started
IBM MQ (message queue) - Getting Started
Home > Search
Before you can understand what MQ (message queue) is, it's helpful to see how data is transmitted without MQ. In this extremely simplified diagram, the sending system transmits data to the receiving system. In this scenario, the data would most probably be something like an email or an SMS message. While this is all fine and dandy, this type of design can produce problems. Most notably, if the receiving system is unable to receive the data (eg. the receving system is down or overwhelmed with requests), the sending system may not be able to move onto the next transmission or may continually try to send the data over and over again (which is a waste of the sending systems resources). MQ resolves these issues.
MQ sit's between the sending system and receiving system, as a sort of broker or proxy. In this way, if the receiving system is unavailable, the sending system does not get trapped in a situation where it cannot move onto it's next transmission or is bogged down trying to send the transmission over and over again. The sending system simply sends the data to MQ and then moves on (fire and forget). In this way, MQ makes it so that data tranmission is asynchronous. If this is something you want to implement, you can install the trial version of MQ server to see if this type of architecture will fit your needs.
After you've installed MQ server, your next move is to create a queue manager. As the name implies, a queue manager manages one or more queues. Enough said.
Then you'll want to create a local queue. Messages will be stored in the local queue. While not necessary, you could now also add the queue to your WebSphere dmgr.
To test things out, you can put a message in the local queue. With the current setup, messages can only be added and removed from the local queue on the MQ server itself, which isn't really pratical from a real world scenario, thus the next step is to configure MQ so that other systems and PUT and GET messages.
In order for another system to be able to PUT a message in the MQ queue, a server connection channel needs to be setup. The server connection channel is the hostname and port (socket) used to connect to the MQ server.
Next, lets configure the listener to expect a certain username and password, so that we have a basic authentication system in place for users that want to connect to our MQ server.
Congratulations! You now have an operational MQ server. Let's test these waters and create a Java application that can PUT a message on the queue. To verify that the message was PUT on the queue, you can display the messages in the queue.

In Is OpenMP (parallel for) in g++ 4.7 not very efficient? 2.5x at 5x CPU, I determined that the performance of my programme varies between 11s and 13s (mostly always above 12s, and sometimes as slow as 13.4s) at around 500% CPU when using the default #pragma omp parallel for, and the OpenMP speed up is only 2.5x at 5x CPU w/ g++-4.7 -O3 -fopenmp, on a 4-core 8-thread Xeon.
I tried using schedule(static) num_threads(4), and noticed that my programme always completes in 11.5s to 11.7s (always below 12s) at about 320% CPU, e.g., runs more consistently, and uses less resources (even if the best run is half a second slower than the rare outlier with hyperthreading).
Is there any simple OpenMP-way to detect hyperthreading, and reduce num_threads() to the actual number of CPU cores?
(There is a similar question, Poor performance due to hyper-threading with OpenMP: how to bind threads to cores, but in my testing, I found that a mere reduction from 8 to 4 threads somehow already does that job w/ g++-4.7 on Debian 7 wheezy and Xeon E3-1240v3, so, this very question is merely about reducing num_threads() to the number of cores.)
• 3
No, there is no simple way to do this fully automatic. But there is stackoverflow.com/q/2901694/620382 + omp_set_num_threads . Again I recommend manually controlling the thread configuration on each system, if feasible. – Zulan Apr 30 '16 at 19:06
• Why was this question downvoted?! – cnst May 2 '16 at 6:35
If you were running under Linux [also assuming an x86 arch], you could look at /proc/cpuinfo. There are two fields cpu cores and siblings. The first is number of [real] cores and the latter is the number of hyperthreads. (e.g. on my system they are 4 and 8 respectively for my four core hyperthreaded machine).
Because Linux can detect this [and from the link in Zulan's comment], the information is also available from the x86 cpuid instruction.
Either way, there is also an environment variable for this: OMP_NUM_THREADS which may be easier to use in conjunction with a launcher/wrapper script
One thing you may wish to consider is that beyond a certain number of threads, you can saturate the memory bus, and no increase in threads [or cores] will improve performance, and, may in fact, reduce performance.
From this question: Atomically increment two integers with CAS there is a link to a video talk from CppCon 2015 that is in two parts: https://www.youtube.com/watch?v=lVBvHbJsg5Y and https://www.youtube.com/watch?v=1obZeHnAwz4
They're about 1.5 hours each, but, IMO, well worth it.
In the talk, the speaker [who has done a lot of multithread/multicore optimization] says, that from his experience, the memory bus/system tends to get saturated after about four threads.
Hyper-Threading is Intel's implementation of simultaneous multithreading (SMT). Current AMD processors don't implement SMT (the Bulldozer microarchitecture family has something else AMD calls cluster based multithreading but the Zen microarchitecture is suppose to have SMT). OpenMP has no builtin support to detect SMT.
If you want a general function to detect Hyper-Threading you need to support different generations of processors and make sure that the processor is an Intel processor and not AMD. It's best to use a library for this.
But you can create a function using OpenMP that works for many modern Intel processors as I described here.
The following code will count the number of physical cores on an modern Intel processors (it has worked on every Intel processor I have tried it on). You have to bind the threads to get this to work. With GCC you can use export OMP_PROC_BIND=true otherwise you can bind with code (which is what I do).
Note that I am not sure this method is reliable with VirtualBox. With VirtualBox on a 4 core/8 logical processor CPU with windows as Host and Linux as guess setting the number of cores for the VM to 4 this code reports 2 cores and /proc/cpuinfo shows that two of the cores are actually logical processors.

Registry Cleaners Can Actually Damage Your Computer
There are lots of registry cleaning software in the market today. Many of these have issues in differentiating between the importance of various registry keys. One registry cleaner may see a particular key as a very dangerous error while another would find it as a necessary operating system record. The operating system may show different errors if that particular key is erased or altered.
In some rare cases, removing or altering a wrong registry key can result in the system failure. The truth is that using an inferior registry cleaner is the main reason for some people to consider this application as risky. The trick is to learn the importance of reviews before installing any software. A reliable registry-cleaning software will never have any damaging effect on your laptop or computer and all registry optimizer or cleaners are different.
It is very crucial to realize a registry cleaner can actually ruin your computer. Registry optimizer are intended to alter some of the most important setup files of your computer, modifying the wrong file can really harm your laptop or computer and the different applications in it. Other than creating complications in different applications, wrong changes in Windows registry can also damage your Windows data files.
One will require a lot of know-how or computer skills before you can work with a registry optimizing tool effectively. The ability to distinguish between genuine registry cleaners and scams on the internet in the most critical skill you require, as many registry cleaning software program offered online are just another way of inviting malware into your laptop or computer.

3 Top Healthcare Information Services Stocks to Buy in 2017
You don't have to buy a biotech, hospital, or medical device stock to invest in healthcare. Some smart picks can be found in stocks of companies that provide tools for other healthcare companies -- for example, healthcare information services stocks.
Three of the best healthcare information services stocks to consider buying in 2017 are athenahealth (NASDAQ: ATHN) , HealthEquity (NASDAQ: HQY) , and Veeva Systems (NYSE: VEEV) . These companies focus on very different segments within the industry, but here's why they're at the top of their respective niches.
Athenahealth: Gunning for the big players
Athenahealth is the leading provider of cloud-based technology to physicians and hospitals. The company has increased revenue by a compounded annual growth rate (CAGR) of 30% over the last 10 years. Even though Athenahealth isn't the new kid on the block like it once was, its management still expects revenue to grow by around 20% annually in the future.
Jonathan Bush, Athenahealth's always-colorful CEO, said a couple of years ago that major rivals Cerner and Epic would "collapse like big black swans." Bush's premise was that these legacy software systems aren't able to support the usability, flexibility, and interoperability that the healthcare industry needs to improve.
Athenahealth's strategy is to leverage the power of its growing network of providers connected on the company's cloud-based platform. The company plans to increase its customers' efficiency and help them grow their market share.
Expanding into other healthcare areas is also important. Athenahealth started out by addressing the physician market but later expanded into the hospital market. Its vision is to build "a unified clinical experience that allows providers to cross environments (e.g., inpatient, outpatient, point-of-care mobile applications, and population health management) without having to log in to different systems."
HealthEquity: Powering the HSA surge
HealthEquity provides a technology platform for consumers to manage health savings accounts (HSAs). The company's revenue increased by more than 40% in both 2014 and 2015. HealthEquity projects similar growth this year.
The company currently serves as the integrated HSA platform for 87 health plans and over 34,000 employer clients. Those health plans include many of the largest in the U.S. As a result, more than one-third of Americans under age 65 are covered by HealthEquity's network partners.
But did Republicans' failure to win support for an Obamacare replacement plan hurt the chances of HSA growth in the future? Not really. HealthEquity benefited from a tremendous increase in HSA usage during a period when the prospects of healthcare legislation other than Obamacare were essentially non-existent.
HealthEquity's CEO, Jon Kessler, stated, "Once you really understand how an HSA plan works, you will never go back to conventional health insurance." As more Americans gain this understanding, HealthEquity will reap the benefits. And if the GOP finally passes an Obamacare replacement, you can bet that HSAs will be a key part of the plan.
Veeva Systems: In the right place at the right time
Veeva Systems is the leading provider of cloud-based software solutions for the life sciences industry. The company claims more than 475 customers, including huge drugmakers and up-and-coming biotechs.
Veeva became the second-fastest software company to reach $500 million in annual revenue. When asked how the company did it, co-founder and president Matt Wallach responded by saying it was a combination of good timing and addressing complex customer needs.
Over the last five years, Veeva's revenue has soared 470%. The company projects 2017 growth of more than 30%. Two key growth drivers will be Veeva's Commercial Cloud and Vault products. Commercial Cloud is the company's core customer relationship management system. Vault is Veeva's cloud-based enterprise content management platform.
Commercial Cloud was launched in 2008, while Vault launched in 2012. Vault's sales growth in its first five years is tracking ahead of the first five years for Commercial Cloud. Veeva is also seeing existing customers implement additional Vault suites after their first year.
One caveat
These three companies have one other common denominator besides being arguably the best at what they do: Their stocks are priced at a premium. Athenahealth stock trades at 37 times forward earnings. HealthEquity's share price is 60 times higher than forward earnings. Veeva stock trades at 53 times forward earnings.
Lofty valuations can translate to higher volatility. On the other hand, all three of these healthcare information services stocks have been rewarded with premium prices because investors like their potential. In my view, Athenahealth, HealthEquity, and Veeva deserve higher valuations than most and remain solid picks for 2017.

Page:Satyagraha in South Africa.pdf/203
nature of Satyagraha is such that the fruit of the movement is contained in the movement itself. Satyagraha is based on self-help, self-sacrifice and faith in God. One of my objects in enumerating the names of European helpers is to mark the Satyagrahis’ gratefulness to them. This history would be justly considered incomplete without such mention. I have not tried to make the list exhaustive, but have tendered the Indians’ thanks to all in selecting a few for especial mention. Secondly, as a Satyagrahi I hold to the faith, that all activity pursued with a pure heart is bound to bear fruit, whether or not such fruit is visible to us. And last but not the least, I have tried to show that all truthful movements spontaneously attract to themselves all manner of pure and disinterested help. If it is not clear already, I should like to make it clear that no other effort whatever was made during the struggle to enlist European sympathy beyond the effort, if effort it can be called, involved in adherence to Truth and Truth alone. The European friends were attracted by the inherent power of the movement itself. | WIKI |
With 5000+ stars and 1500+ forks on GitHub, Robot framework has been a go-to-option for many organizations who are aiming for Agile and Test Driven Development (TDD) where developers should write functional code only when there is a test that has failed. Robot framework allows acceptance testing, behaviour driven testing, Robotic Process Automation (RPA), and Acceptance test-driven development (ATDD).
It offers an extensible keyword driven approach to perform automation testing. The learning curve is simple as you don’t need to have a programming experience to get started with the Robot framework.
Robot framework is written in Python, however, it is not restricted to that. You can implement keywords in Robot framework using Python, Java, JavaScript, Perl, .Net and PHP.
This Robot framework tutorial will help you run your first Selenium testing script with Python. Further, we will look into running automation scripts for more complex scenarios using Robot and Selenium. Selenium would be used to implement automated browser testing using keyword driven testing with Robot in Python.
What Is Keyword-Driven Testing(Table-Driven Testing)?
Keyword-driven testing is a form of testing where data tables are developed with relevant keywords and the keywords being used are agnostic of the test framework being used for testing. The purpose of the keywords is to broadly describe the actions that need to be performed for a particular test.
The primary advantage of keyword-driven testing is that testers can make use of keywords to describe the action of a particular test. It can be used for both manual and automated testing.
There are different types of keywords.
1. Higher-level keywords – These keywords can be used to test particular aspects of a system.
2. Lower-level keywords – These keywords describe the actual functionality testing which is a combination of a number of lower-level keywords.
3. Technical keywords – These are the ones that are used to execute the tests.
Hence, in a keyword-driven test, you need to first identify the right set of higher-level and lower-level keywords and then associate actions with these keywords.
For example, if you are responsible for testing the login screen of a banking website, your keywords would be Open Browser, Login, Enter password, Logout, Close Browser, etc. All these keywords are self-explanatory and this is what makes keyword-driven testing more effective.
Now that we have touched upon the basics of keyword-driven testing, let’s deep dive into the architecture of Robot framework.
Robot Framework Architecture
Robot framework has a highly modular architecture as seen in the figure below. It is a technology-independent framework that uses keyword-driven testing. Users can create higher-level keywords from the existing keywords. Along with the generation of keywords, users can also create test libraries in different programming languages.
Robot Framework Architecture
Test Data
Test data, the first layer of the Robot framework is in a tabular format. Since the data is in a tabular format, maintaining the data is very easy. This test data is the input to the Robot framework and once it receives the test data, it starts processing the test data and on execution, it generates reports & logs. The report is in HTML and XML format. The generated reports offer detailed information about every line that is executed as a part of the test case.
Robot Framework
The primary advantage of the Robot framework is that it is agnostic of the target under test. The interaction with the layers below the framework can be done using the libraries [built-in or user-created] that make use of application interfaces.
Test Libraries & Test Tools
Since the Robot framework only interacts with the other layers in the system using libraries, it makes the code portable and maintainable. Libraries are normally imported at the start of the implementation [in the *** Settings *** section], example is shown below
*** Settings ***
Library Selenium2Library
……………………………..
*** Variables ***
……………………………..
……………………………..
System Under Test
This is the actual target on which the testing activity is performed. It could either be a website or a web app. Libraries act as an interface between the Robot Framework and the system under test. Hence, there is no way through which the framework can directly talk to the system under test. The Robot framework supports various file formats namely HTML, TSV (Tab Separated Values), reST (Restructured Text), and Plain text. As per the official documentation of Robot framework, the plain text format is recommended.
Prerequisites for Robot Framework Tutorial with Python and Selenium
So far in this Robot framework tutorial, we have covered the basics of Robot framework and the building blocks that constitute the framework. Let’s set up the prerequisites for running Robot framework with Selenium.
Here is everything you need for this Robot framework tutorial:
1. An IDE, download PyCharm Community Edition
2. Install the Intellibot Plugin in PyCharm for Robot framework.
3. Install Robot framework
4. Specify Selenium as an external test library.
Let us look at each of these, one by one.
Install The Intellibot Plugin
Once you have installed the PyCharm IDE, you need to install the Intellibot plugin for Robot framework. Go to File -> Settings -> Plugins -> Search for Intellibot in the plugins marketplace -> Install the plugin -> Restart the IDE.
Install The Robot Framework
To install Robot framework, please execute the below command in the terminal section of PyCharm IDE.
pip install robotframework
Once installed, you can check the version of the Robot framework being used by using the command:
robot–version
pip installation
The Robot framework supports a number of command-line options and covering each option is beyond the scope of this Robot framework tutorial. You can execute the following command to get more information about each option.
robot --help
Automation Framework
Install Selenium Library For Robot Framework
The Robot framework has a set of Robot standard libraries that are supported along with the framework. Usage of these libraries does not require installation of a separate module. Some of the standard libraries that are included in the normal installation are:
1. Operating System
2. Remote
3. Process
4. Reserved
5. Screenshot
6. String
7. Telnet
8. XML
9. DateTime
You can find the complete list by visiting the official documentation of robot.libraries package. Any test library that is not a part of the standard libraries is considered as an external library.
There are a number of external libraries that are created by the Robot framework open-source community. To install , you just need to initiate the below command from the terminal.
pip install <robotframework-externallibrarypackage>
As we would be using the Robot framework with Selenium, the next step in the Robot Framework tutorial is to install the SeleniumLibrary as an external test library to Robot. In order to install the SeleniumLibrary, run the below command on the terminal.
pip install robotframework-SeleniumLibrary
Terminal SeleniumLibrary
The SeleniumLibary is mandatory for automation testing with Selenium & Python using the Robot framework. SeleniumLibrary supports Python version 2.7, 3.4, or newer. This library is forked from Selenium2Library, hence you can also install the same library using the below command.
pip install robotframework-Selenium2Library
Other than the Robot framework for Selenium with Python, the SeleniumLibrary also offers support with PyPy and Jython; though these topics would not be covered as a part of this Robot framework tutorial. I would be sure to cover them in my upcoming articles so make sure to hit the bell icon on blog to stay tuned.
Apart from Selenium, some of the other popular Robot External Libraries are
1. HTTP
2. Database
3. SSH
4. Android
5. iOS
6. MongoDB
Here is a simplistic view of the .robot script/file which contains all of the necessary libraries both internal and external which might be utilized by the test cases.
Robotscript
Also Read: Parallel testing in Selenium with Python
Now that you have everything set up correctly, it is time to get your hands dirty with Robot and Selenium test execution.
Should You Use Robot Framework or Selenium WebDriver, or Both?
Many developers & testers have the confusion whether they should use Robot framework or Selenium WebDriver in itself would suffice. There is a huge difference between both of them – Robot is a test framework that makes use of test libraries (standard & external) to execute tests, whereas Selenium is only a WebDriver/library that requires the support of test automation runners in order to perform test execution.
Robot framework can be used to perform different types of automated tests, whether these tests are about UI testing or API level testing. SeleniumLibrary module which was described above enables Selenium framework support in Robot.
The SeleniumLibrary interfaces with the Selenium WebDriver, which in turn executes the commands on the respective browser under test. The interaction between the SeleniumLibrary and Selenium WebDriver is abstracted from the developer of the test script.
So yes, you need both Selenium WebDriver and the Robot framework.
Run Your First Robot Framework Script With Selenium And Python
Test cases using the Robot framework are created using Keywords. As a part of the SeleniumLibrary, a number of Keywords can be used for Test Suite implementation. Before using the Keywords, you need to first import the SeleniumLibrary in the Robot script (in the *** Settings *** section), this can be done using Library SeleniumLibrary or Library Selenium2Library.
Here are some of the most prominently used Keywords from the SeleniumLibrary.
SeleniumLibrary Keywords
However, the choice of keywords would depend on your test suite or test case. You can have a look at all the Keywords supported by SeleniumLibrary in the official documentation of SeleniumLibrary Keywords.
It is now time to get to the crux of this Robot framework tutorial and have a look at a sample implementation that uses Robot Framework and SeleniumLibrary.
Test Scenario 1: Perform a Google search with the search query ‘LambdaTest’.
Keywords to use –
Wait Until Page Contains, Wait Until Element Is Visible, Input Text, and Submit Form. Since these Keywords are part of the SeleniumLibary/Selenium2Libary, the required library is imported before we start the actual operation.
*** Settings ***
Library Selenium2Library
Suite Setup Open browser ${URL} ${BROWSER}
Suite Teardown Close All Browsers
*** Variables ***
${URL} http://www.google.com
${BROWSER} Chrome
# Alternately you can also use xpath=//*[@id="tsf"]/div[2]/div/div[1]/div/div[1]/input

Title
Flux quantization and Aharonov-Bohm effect in superconducting rings
Author
Abstract
Superconductivity is a macroscopic coherent state exhibiting various quantum phenomena such as magnetic flux quantization. When a superconducting ring is placed in a magnetic field, a current flows to expel the field from the ring and to ensure that the enclosed flux is an integer multiple of h/(2|e|). Although the quantization of magnetic flux in ring structures is extensively studied in literature, the applied magnetic field is typically assumed to be homogeneous, implicitly implying an interplay between field expulsion and flux quantization. Here, we propose to decouple these two effects by employing an Aharonov-Bohm-like structure where the superconducting ring is threaded by a magnetic core (to which the applied field is confined). Although the magnetic field vanishes inside the ring, the formation of vortices takes place, corresponding to a change in the flux state of the ring. The time evolution of the density of superconducting electrons is studied using the time-dependent Ginzburg-Landau equations.

Modern Greek/Lesson 04.3
= Lesson 4.2: Second Conjugation Verbs =
Class II verbs have the accent on the final syllable. They are divided into two subcategories, IIA which end in άω or class IIB which end in ώ. First conjugation verbs were covered in the previous lesson.
Class IIA -άω
These end in άω, though sometimes the α is omitted. In this case the first person singular looks like a class IIB verb. [I'm not sure how you tell it's not in this case, other than learning. Thankfully dropping the α is fairly rare apparently, and every ending except first person singular is different so it should be easy to spot].
The endings for a class IIA verb are -άω, -άς, -άει, -άμε, -άτε, -άν. Using the summary notation introduced in the previous lesson and the example verb μιλάω - to speak:
There are a number of useful verbs that are of this form, given here in the 1st person:
Class IIB -ώ
Class IIB verbs look a lot like class I verbs, the endings are the same letters in all cases except 2nd person plural, and the accent remains on the final syllable. So the endings are -ώ, -είς, -εί, -ούμε, -είτε, -ούν.
[Class IIB verbs ended with -έω previously, hence they are historically more similar to class IIA even if at first glance they look more like class I. The key is whether the accent is on the stem or the final syllable.]
An example using the summary notation again, μπορώ - to be able (can):

Working with a Timer in C#: The Basics
WEBINAR: On-demand webcast
How to Boost Database Development Productivity on Linux, Docker, and Kubernetes with Microsoft SQL Server 2017 REGISTER >
The following listing presents a neat little program that is not well designed. It is simple, and there is nothing complex presented in it. It simply prints the time to the console. Forever.
Listing 1. timer.cs - Displaying the time.
1: // Timer01.cs - Displaying Date and Time
2: // Not a great way to do the time.
3: // Press Ctrl+C to end program.
4: //------------------------------------------
5: using System;
6:
7: class myApp
8: {
9: public static void Main()
10: {
11: while (true)
12: {
13: Console.Write("\r{0}", DateTime.Now);
14: }
15: }
16: }
*** Output ***
5/26/2003 9:34:19 PM
*** Analysis ***
As you can see, this listing was executed at 9:34 on May the 26th. This listing presents a clock on the command line. This clock seems to update the time every second. Actually it us updating much more often than that; however, you only notice the changes every second when the value being displayed actually changes. This program runs until you break out of it using Ctrl+C.
In line 13, a call to DateTime is made. DateTime is a structure that is available from the System namespace within the base class libraries. This structure has a static method called Now that returns the current time. There are a large number of additional data members and methods within the DateTime structure. You can check out the .NET Framework class library documentation for information on these. There are also a few other aritcles here on CodeGuru.com
A better way to present a date on the screen is with a timer. A timer allows a process—in the form of a delegate—to be called at a specific time or after a specific period of time has passed. The framework includes a class for timers within the System.Timers namespace. This class is appropriately called Timer. Listing 2 is a rewrite of listing 1 using a Timer.
Listing 2. Timer02.cs - Using a timer with the DateTime.
1: // Timer02.cs - Displaying Date and Time
2: // Using the Timer class.
3: // Press Ctrl+C to end program.
4: //------------------------------------------
5: using System;
6: using System.Timers;
7:
8: class myApp
9: {
10: public static void Main()
11: {
12: Timer myTimer = new Timer();
13: myTimer.Elapsed += new ElapsedEventHandler( DisplayTimeEvent );
14: myTimer.Interval = 1000;
15: myTimer.Start();
16:
17: while ( Console.Read() != 'q' )
18: {
19: ; // do nothing...
20: }
21: }
22:
23: public static void DisplayTimeEvent( object source, ElapsedEventArgs e )
24: {
25: Console.Write("\r{0}", DateTime.Now);
26: }
27: }
*** Output ***
5/26/2003 10:04:13 PM
*** Analysis ***
As you can see, this listing's output is just like that of the previous listing. This listing, however, operates much better. Instead of constantly updating the date and time being displayed, this listing only updates it every 1000 ticks. 1000 ticks is equal to one second.
Looking closer at this listing, you can see how a Timer works. In line 12 a new Timer object is created. In line 14 the interval that is to be used is set. In line 13 the method that is to be executed after the interval is associated to the timer. In this case, the DisplayTimeEvent will be executed. This method is defined in lines 23 to 26.
In line 15 the Start method is called this will start the interval. Another member for the Timer class is the AutoReset member. If you change the default value from true to false, then the Timer event will happen only once. If the AutoReset is left at its default value of true, or set to true, then the Timer will fire an event and thus execute the method every time the given interval passes.
Line 17 to 20 contain a loop that continues to operate until the reader enters the letter 'q' and presses enter. Once the user does this, the end of the routine is reached and the program ends; otherwise, the program continues to spin in this loop. Nothing is done in this loop in this program. You can do other processing in this loop if you desired. There is no need to call the DisplayTimeEvent in this loop because it will be automatically called at the appropriate interval.
This timer is used to display the time on the screen. Timer and timer events can be used for numerous other programs as well. You could create a timer that fires off a program at a given time. You could create a backup routine that copies important data at a given interval. You could create a routine to automatically log off a user or end a program after a given time period with no activity. There are numerous ways to use timers.

Nighoj
Nighoj is a village in Ahmednagar District, Maharashtra, India. It is about 90 kms away from Pune and had naturally created potholes (tinajas) on the riverbed of the Kukadi River.
Geologists indicate that formerly there was greater rainfall in the area and that the Kukadi River flowed out from the highlands, scouring the bedrock and forming the potholes and the gorge.
Religion
The majority of the population in Nighoj is Hindu, but there are also Muslims. There are several temples in the village, one of which, the Malaganga temple, is located on the bank of the gorge on the old river-bed itself. | WIKI |

Governor of the Bastille
The Bastille or Bastille Saint-Antoine was completed in 1383. The commander of the Bastille was its governor, and was previously called capitaine.
History
In 1367, King Charles V ordered the construction of the fort et bastide Saint Anthoine lez Paris, literally fort and bastide of Saint Anthony close to Paris, which will later take the name of Bastille. The works will be completed twenty years later, in 1387, under the reign of Charles VI. The first captain-governor was a close acquaintaince of the King, already chamberlain under the two previous reigns: Jehan de La Personne, knight, viscount of Acy, lord of Beu and Nesle-en-Tardenois, chamberlain of the King. He is quoted in numerous documents between 1386 and November 1404, date of his death that are now held in the department of manuscripts of the Bibliothèque nationale de France. The last governor to hold this position, the unfortunate Bernard-René de Launay, appointed in 1776, was beheaded on 14 July 1789 and replaced by a provisional governor during the demolition of the building.
At the end of the Ancien Régime, the governor of the Bastille was reduced to being a subordinate of the lieutenant-general of police. He could do nothing without the express order of this magistrate. A governor who would have dared to adhere to the regulations and to only recognize orders given by the King, would not have remained long in command. If he wanted to remain, he had no other rules to follow than the orders of the lieutenant-general of police, or even those of a simple police commissioner
Article 1 of the regulation of 20 September 1764, signed by the King stated:
"'The governor who commands, or any other officer, shall recognize only the orders of His Majesty and those given to him by the secretary of state.'"
However, a letter dated 23 September 1764, signed by the Secretary of State, authorizes the following:
"'I enclose here, Sir, the regulations which the King has thought fit to render for the service of the Bastille. The King finds it fitting that when the Lieutenant-General of Police sends you prisoners, you receive them on a letter from him until a letter can be sent to you in good form, as has often been used and according to that circumstances that demand it. You will do well to use them in the same way, for the visits which the lieutenant-general of police thinks they can allow prisoners to receive and who do not require a formal order, but only a letter from him.'"
The regulation also ordered the exact registration of the first and last names of prisoners for entry, exit and death, but the ministerial instruction authorized the substitution of surnames and given names. This is how Jean Henri Latude was registered under his real name, later under the names of Danry, Maiville and Villemain. The Man in the Iron Mask was buried under the name of Marchiali with a false indication of age.
The position of governor of the Bastille, all military ranks, all military posts, the provincial governors, were negotiated as bills of exchange. It was only a matter of obtaining the approval of the King, it was a common commercial sale. These transactions were considered normal at the time. The purchaser of the title of Governor of the Bastille was always certain of a good deal if he lived a long life. A year or two in office, was largely sufficient to repay the purchase.

Jehan de La Personne, vicomte d'Acy
Councillor, Minister of State and Chamberlain of the Kings Jean II, Charles V and Charles VI, Jehan de La Personne was the first Captain of the Bastille. One of the receipts quoting him dates from 12 December 1387. It is addressed to him by Jehan le Flamenc, Treasurer of the Wars of the King, "for the state of his wages as captain and those of the abovenamed seven squires and ten arbalsters of foot of our company, having served and to serve in this present war to the guard the safety and defense of said fort and bastide Saint-Antoine."
Lord of Saint-Georges
On the death of his first captain, the Lord of Saint-Georges received in 1404 his command from the King of France, Charles VI.
Louis VII, Duke of Bavaria
Prince Louis VII of Bavaria, brother of Isabeau of Bavaria and uncle of the Dauphin Charles.
Thomas de Beaumont
Thomas de Beaumont had left Paris with the troops he could muster to aid the Constable de Richemont, and was killed in the battle which took place between Saint-Denis and Pierrefitte.
Tanneguy du Chastel
Tanneguy du Chastel, Provost of Paris succeeded, in all probability, as Governor of the Bastille to the Duke of Bar in 1417–1418.
During the Armagnac–Burgundian Civil War, Paris surrendered to Jean de Villiers de L'Isle-Adam, captain of a troop of supporters of the Duke of Burgundy. Tanneguy succeeded in removing the Dauphin who was amidst his enemies and protected him by welcoming him to the Bastille. On 29 May 1418, the Dauphin left the Bastille to take refuge in Bourges with loyalists.
"Tanneguy ran to the Dauphin's room and, finding him asleep, wrapped him in one of his sheets and had him brought to the Bastille. The Dauphin slept there only one night, and the next morning he went to Melun and from there to Montargis. Tanneguy had returned to Paris by the Porte Saint-Antoine, of which he was the master because of the Bastille."
Robert de Canni
Arriving at the Bastille, Tanneguy du Chastel, accompanied by Marshal Pierre de Rieux and Arnaud Guillaume de Barbazan, and 1600 men marched on the Hôtel Saint-Pol, shouting "Vive le Roi et le Connétable d'Armagnac!" Guy de Bar and Jean de Villiers de L'Isle-Adam met them with 5000-6000 men, pushing them back to the entrance of the Bastille. Hector de Saveuse, Jean de Luxembourg-Ligny, and several other Burgundian captains arrived from all directions to lend aid. They were soon strong enough to besiege and take the Bastille, later bestowing command upon Robert de Canni, Lord of Varennes.
Robert de Canni was a personal enemy of Charles, Duke of Orleans, who had seduced and dishonored his wife.
Philippe l'Huillier
Philippe l'Huillier, Lord of Cailly and Manicamp, was chamberlain to King Louis XI.
Jean Bussy-Leclerc
Jean Bussy-Leclerc, prosecutor in the Parlement of Paris, was made Captain of the Bastille by the Duke of Guise in 1588 after the Day of the Barricades.
Antoine Dumaine Dubourg l'Espinasse
Dubourg l'Espinasse or Bourg de Lespinasse or Bourg de l'Espinasse.
In 1588, under Henri III, the Duke of Mayenne had during the Wars of Religion entrusted command of the Bastille to Antoine Dumaine Dubourg l'Espinasse, also known as Antoine du Maine, Baron of the Bourg de Lespinasse. He maintained it until 22 March 1594.
Dubourg surrendered to Henri IV only by capitulation, three days after Paris was surrendered to him by the governor of the city, Charles de Cossé, Duke of Brissac, and once he was certain that the Duke of Mayenne was unable to relieve him. Dubourg had exhausted his provisions and munitions of war; he left the fort "bagne et vie sauve".
The same day Henri IV entrusts command of the Bastille to Devic.
Asked to recognize Henri IV as his king, he replied that he had given his faith to Charles de Mayenne and added that Brissac was a traitor. Indeed, the Governor of Paris had surrendered to Henri IV for 1,695,400 livre.
On 6 March 1597, Dubourg created the Regiment of Bourg de Lespinasse with which he participated in the Siege of Amiens, under orders of Henri IV.
Devic
There is not much on Devic.
Henri IV entrusted him with command of the Bastille on 22 March 1594, due to the honorable services which he had rendered in its capture. "He was, says the story, a man of rare merit". He was Governor of Saint-Denis before taking the Bastille and will then be Governor of Calais where he died in 1610.
Maximilien de Béthune de Sully
In 1601, Maximilian de Bethune, Duke of Sully, Grand Master of the Artillery of France, Grand Voyer of France and Superintendent of Finances is named by Henri IV governor of the Bastille.
It was here that Sully deposited the royal treasure. At the death of Henri IV, in 1610, there were 33,000,000 livre in store. In 1611, Sully returned the governorship of the Bastille to Louis XIII and received a compensation of 60,000 livre.
Marie de' Medici (Joachim de Châteauvieux)
In 1611, Marie de' Medici became the governess of the Bastille, but entrusted custody to Joachim de Châteauvieux, her knight of honor who took direct command as a lieutenant of the Queen Mother and Regent.
Joachim de Châteauvieux, born on 25 January 1545, son of Claude de Châteauvieux, knight, lord and baron of Fromente, Bailiff of Bresse, and Marie-Salomé de Montchenu, daughter of Marin and Antoinette de Pontbriand.
He was a knight, Baron of Verjon and La Chatre, Count of Confolens, Knight of the Order of the Holy Spirit in 1583, Knight of Honor of Queen Marie de' Medici, Bailiff of Bresse and Bugey, Governor of Burgundy, died without an alliance on 13 January 1615. In 1569, he was captain of the Garde Écossaise and accompanied Henri de Valois, elected in 1573 Rzeczpospolita of Poland–Lithuania under the name Henryk Walezy.
He fought alongside the King during the popular uprising of 12 May 1588.
After the death of Henri III, he served Henri IV and distinguished himself at the Battle of Fontaine-Française.
François de Bassompierre
François de Bassompierre received, in 1617, the captaincy of the Bastille of Louis XIII. He had sixty Swiss Guards under his command and remained only 8 to 10 days before relinquishing command to the Constable de Luynes.
Charles d'Albert
After the resignation of Marshal Bassompierre, the constable, Charles Albert, Duke of Luynes, receives, in 1617, the governance of the Bastille. Marie de' Medici having discovered that he was intriguing against her dismissed him after only a few months and handed the post to Vitry.
Nicolas de L'Hôpital
After the resignation of Marshal Bassompière and the Duke of Luynes, Nicolas de L'Hospital, Duke of Vitry, was the third governor of the Bastille in the year 1617.
The Duke of Vitry was in command when the Marechale d'Ancre, Leonora Dori, was conducted there, as she jailed the murderer of her husband, Concino Concini.
Léon d'Albert
At the beginning of 1626, the Duke of Vitry ceded command to Leon d'Albert, Marquis de Bréauté, Duke of Piney-Luxembourg, brother of the Constable de Luynes who had been governor of the Bastille nine years earlier.
François de L'Hospital
On 7 May 1626, François de L'Hospital, lord of the Hallier, brother of Maréchal de Vitry, drove from the Bastille the company of the Duke of Piney-Luxembourg.
His taking office was an event; On 7 May he took command of the fortress at the head of a detachment escorting two new prisoners, the Duke of Modena and Dangent. He immediately dismissed the company established by his predecessor and replaced it with thirty Swiss Guards commanded by the Garde-du-corps.
Charles Leclerc du Tremblay
Charles Leclerc du Tremblay was appointed by Richelieu as Governor of the Bastille, instead of captain, changing the status of the military citadel to a royal prison.
Under the regency of Anne of Austria the Bastille was besieged once more. On 12 January 1649, after exchanging a few volleys, the fortress fell into the hands of the frondeurs who conferred command upon Louvière Broussel.
Charles Leclerc du Tremblay was the brother of François Leclerc du Tremblay, better known under the name of Father Joseph, the "Grey Eminence" of Richelieu.
Louvière Broussel
Louviere, or La Louviere, was the son of the Parisian councillor Pierre Broussel.
Pierre Broussel, who played an important role during the War of the Fronde in 1648, had been deprived of his office as governor of the Bastille for his role in the Parlementary Fronde. He then invested his son, Louvière.
During the peace between the Parlement and the King in 1649, it was stipulated that the Bastille would be surrendered to His Majesty on March 11, but this treaty was not confirmed until the following April 1. It was thus agreed that the King would not press delivery of the Bastille, and that Louviere would retain its command. Louvière handed over the Bastille on 21 October 1652, during the Fronde, to La Bachellerie sent by the King.
Antoine de Loyac de la Bachellerie
Antoine de Loyac, Lord of the Bachellerie, Fage, Lavez and Puy-Donnarel, was the second son of Jean-Baptiste de Loyac and Jeanne de Plaines.
When Louvière handed him the Bastille on 21 October 1652, La Bachellerie did not have the title of Governor of the Bastille. It was by order of the Chancellor that he went with an escort to the assembly of the clergy, sitting at the Grands-Augustins stopped there and led to the Bastille the Abbot of Saint-Jean d'Angély.
On 2 November 1638, Antoine de Loyac, Lord of the Bachellerie, was captain in the Regiment of Montmège.
In 1647, he was a gentleman of the King's Chamber.
In 1653, he is commander of the Île de Ré and Governor of the Bastille.
He married on 1 May 1639 with a young lady, Gabrielle de Maruc, daughter of Annet de Maruc, squire, Lord of Charbonnier and Gabrielle de Gibanel, with whom he had:
* Jean-Baptiste de Loyac, squire, Lord of the Bachellerie and Fage captain of a company in the Regiment of Picardy

* Charles de Loyac, squire, Lord of the Fage, lieutenant in the Regiment of Picardy
* Anne de Loyac, legatee of her father for the sum of 20,000 livre
François de Montlezun
François de Montlezun, lord of Besmaux was captain of the guards of Cardinal Mazarin and obtained his brevet of governor in 1658.
François de Monlezun, Lord of Besmaux kept this lucrative and respectable post for more than forty years. He largely succeeded in compensating himself for the payment of 90,000 francs, the price of his predecessor's resignation.
He died at his post on 18 December 1697, 88 years old and buried in Carmes-Déchaux.
In the third volume of the Vicomte de Bragelonne, Alexandre Dumas introduces the character of the Governor of the Bastille under the name of Baisemeaux de Montlezun.
Bénigne Dauvergne de Saint-Mars
Bénigne Dauvergne de Saint-Mars was appointed Governor of the Bastille in 1698. He arrived there on 18 September with the Man in the Iron Mask and his lieutenant, Durosarge.
Durosarge and Saint-Mars had since 1671 kept this prisoner at Pignerol and then, this fortress having been returned to the King of Sardinia, had relocated to Île Sainte-Marguerite, where he had by order built a prison.
The diary of Dujonca, major of the Bastille, indicates: "'From Thursday, 18 September 1698, at three o'clock in the afternoon, Monsieur de Saint-Mars, Governor of the Bastille, coming from his command of the Île Sainte-Marguerite, brought with him a prisoner whom he had at Pignerol, who is still masked and whose name is not said.'"
Five years later, on 19 November 1703, Lieutenant Durosarge signed the Act of Interment of this prisoner whose name and motive of imprisonment no one knew.
Dujonca's diary reads: "'From Monday, 19 November 1703, the unknown prisoner, always masked by a black velvet he had been keeping for a long time, found himself a little ill yesterday after leaving Mass. He died today at ten o'clock in the evening, without having had a great illness.'"
Governor Saint-Mars died at his post on 18 September 1708.
Charles le Fournier de Bernaville
Charles le Fournier de Bernaville passed from the lieutenance of the Château de Vincennes to governance of the Bastille after the death of Saint-Mars on 12 March 1708.
Le Fournier had successively been a valet de chambre, secretary of the Maréchal de Bellefonds, and governor of the dungeon of Vincennes. His services earned him the epaulets of the lieutenant du roi and the title of Chevalier de Bernaville. It is under this name that he made himself famous for his greed and ferocity.
He died at his post on 8 December 1718, at the age of 74.
René Jourdan de Launay
René Jourdan de Launay was governor of the Bastille in 1718.
Born in Golleville on 2 June 1673, he was a squire, Lord of Launay, Bretonnière, Hennodière, Mesnil and La Motte, Lord of the Varengère (1746), and knight of the Royal and Military Order of Saint Louis.
He was first married in 1721 to Catherine Charlotte Sevin de Quincy, daughter of General Charles Sevin de Quincy and Genevieve Pecquot de Saint-Maurice, who died on 27 February 1736 at the age of 36 years.
On 12 April 1736, he married Charlotte Renée Aubry d'Armanville, Lady of Issy and Pourpry, with whom he had Bernard René Jourdan de Launay; who was to become the final governor of the Bastille.
He died suddenly in 1749, aged 76, near Saint Benoit in Paris while leaving Madame Beuclerc's home.
Pierre Baisle
Pierre Baisle was appointed Governor of the Bastille on 6 August 1749.
He was a Bordeaux man exempt from the Garde-du-corps, captain of the Regiment of Champagne and lieutenant du roi at the Château de Vincennes.
He died at his post on 5 December 1758.
François-Jérôme d'Abadie
François-Jérôme d'Abadie born in Grenade-en-Marsan, former captain in the Regiment of Piedmont having the rank of colonel, and lieutenant du roi in the Bastille since 1 December 1750, was appointed governor on 8 December 1758 and succeeded Pierre Baisle.
A Governor of the Bastille was subordinate to the Lieutenant-General of Police. He could do nothing without the express order of the magistrate, and Francois-Jerome d'Abadie thought himself obliged to take the orders of the Chief of Police before allowing a prisoner to shave.
A prisoner bothered by his long beard had asked the Governor to allow him to shave. The Governor had ordered Major Chevalier to write to the Chief of Police. A copy of Chevalier's pleading on 31 May 1756:
"'Monsieur Pizzoni asks to write to you; we await your orders accordingly. This prisoner has nothing to wear, we lend him the store, chemises, handkerchiefs, bonnets, nightclothes and slippers. Monsieur Pizzoni has been here since the 17th; he has not yet been shaved, he asks in favor of it. I have the honor ... '"
The Lieutenant of Police replied in the margin on 3 June 1756:
"'I would like him to write to me and shave him'."
François-Jérôme d'Abadie died on 18 May 1761 and was succeeded by Antoine-Joseph de Jumilhac.
Antoine-Joseph de Jumilhac
After the death of Abadie in 1761, it was Antoine-Joseph-Marie Macosi de Jumilhac, First Gentleman of Stanisław Leszczyński, Duke of Lorraine and Bar, that succeeded to governance.
Major Chevalier still officiated in 1771. On September 13, he wrote to the Lieutenant-General of Police:
"'The head of Monsieur La Riviere is always heated and I begin to despair that his poor head may not heal without the remedy ... With profound respect ... '"
On the sidelines the magistrate wrote: "To hang"
Bernard-René Jourdan de Launay
Bernard-Rene Jourdan de Launay was the last Governor of the Bastille and took his post in October 1776. He paid Jumilhac 300,000 livres for his post as governor.
The Marquis de Launay was born in the Bastille in 1740. His father, René Jourdan de Launay, had already been governor for twelve years and died there nine years after his birth. He was a Black Musketeer of the King, officer in the Gardes Françaises until 1763–1764, then captain of a cavalry regiment.
During the Storming of the Bastille on 14 July 1789, De Launay was arrested and escorted to the town hall by one of the leaders of the Revolution, Pierre-Augustin Hulin. In the Place de Greve the furious crowd attacked the escort, assaulting and eventually beheading Governor Launay.
Prosper Soulès
After the capture of the fortress, Prosper Soulès assumed the interim duties of acting commander. | WIKI |

The subject of Empire’s Progeny is the long, slow development of racial ideas and structures over the course of European imperialism in the Americas, especially (but not limited to) the Spanish and Portuguese empires. Simply put, at the end of the Middle Ages, there was no such idea as race in the European imagination — not at least as race is commonly defined today. Excepting the Americas and Australia, Europeans knew a great deal about the diverse peoples of the world: trade, travel, and migration had brought them contact with myriad peoples from Africa and Eurasia. Although Europeans had various ideas about what made the world’s peoples different, they did not think in the modern terms of race: that is, they did not conceive of humanity as divided into biologically fixed “races.” Instead, the primary distinctions they drew were between Christian vs. heathen, civilized vs. barbarous, and nobility vs. commoners.
Europeans did not conceive of themselves as Europeans nor did they think of themselves as white! Instead, most knew themselves by their kingdom and village, their faith, their trade and social status, and their degree of urbanity. “Race” at the time had none of our modern connotations; rather, the word strictly meant lineage. What concerned Christians living in Spain was to ensure that their family lineage retained its “blood purity.” Their paramount concern was to ensure that lines of nobility remained clear of commoner impurities and that Christian families preserved themselves from any taint of Jewish or Muslim (Moorish) blood. Anyone with any social standing at all to defend spent their lives trying to show that their parents, grandparents, great-grandparents and so on were all “true Christians” and that nowhere along the family line was there any religious deviance. Violence was commonly resorted to in order to ensure that offspring brought no dishonor upon the family lineage by marrying low (though in the case of men affairs with lower class women were commonly indulged). Race and identity, thus, were about religion and nobility. Careers, political power, wealth, and one’s place in Heaven were all tied to having an honorable pedigree.
Contact and the conquest of the Americas very much confounded the European social imagination. Until that time, all the peoples that Europeans knew about were more-or-less consistent with classical sources of learning (i.e. the Greeks) and the Bible, which they took to be a comprehensive explanation of the world. After Columbus, however, suddenly they had to account for the Americas, which did not fit onto any map and which were populated by peoples that the Bible had made no mention of. From 1492 until the late 1500s, there was a lot of uncertainty and much experimentation to define who these peoples were. You are probably aware of the misnomer “Indian,” which comes from the early misconception that the Caribbean Islands (the “West Indies”) were part of the “East Indies” (i.e. East Asia). The word “Indian” stuck, but what it meant and to whom it applied remained contested for the next several hundred years.
People of African descent first arrived in the Americas with Christopher Columbus. In the early years, most were slaves, some were not, but together they had variety of social roles and lived very different lives as sailors and soldiers, clerks and porters, builders and cobblers, etc. However, as the Portuguese and Spanish regimes matured and became dependent on exploiting labor, they soon found that enslaved indigenous peoples were dying at unsustainable rates due to harsh treatment and communicable diseases. The imperial solution was to import large numbers of captured and purchased Africans to work in mines and on plantations, amounting to around 5 million sent to Brazil and 4.5 million to Spanish, French, and British islands in the Caribbean (the future United States received about 450,000). In the European Christian imagination, these were “children of Ham” (Noah’s cursed son), who, because of such ignoble parentage and savage customs were “slaves by nature.” Over the following 300 years, slavery became a more and more standardized institution, built around plantation agriculture and the selling and buying of enslaved Africans. Still, the life experience of people of African descent and how the social category of “Negro” was applied to them varied immensely in time and space depending on many circumstances.
Imperial rulers saw their empires as populated by three main types of humans: Spaniards/Portuguese, Indians, and Africans (negros was the term they used). However, imperialists also found themselves trying to rule over ever more biologically, socially, and culturally mixed populations. This was all the more complicated because socioracial difference was conceived as not only a matter of biological heritage, but also as a matter of religiosity, culture, and behavior. The result was discombobulating. What was one to think of a woman whose mother was known to be part African and part Spanish, whose father was thought to be part Indian and part African, who claimed to descend from a line of Aztec noblemen, comported herself with all the refinements of Spanish high society, was as devout as a priest, and was a healer providing traditional native medicine to wealthy Spaniards?
To understand what notions socioracial difference meant and how they were experienced in the past, it is critical that we think very specifically about the situations in which these terms were used and by whom. For instance, if we ask, “What did being Indian mean to an indigenous peasant in rural Oaxaca (a state in Mexico) in the 1600s?”, the short answer is likely “it meant if he was going to sue his neighbor he would have to go the court for Indians, but most of the time he didn’t think of himself as an Indian at all, but as a maguey farmer, Zapotec speaker, and community member of such-and-such village. The Spanish governor in the regional capital, on the other hand, thought all the time about who counted as an Indian, as this dictated the flow of taxes, the opportunities for graft, and the lines of authority and jurisdiction. Defining Indians was also critical to his sense of self-worth and honor, for he was proud not to be one, and his life was organized around making sure he and his progeny enjoyed all the privileges that went with being recognized as a Spaniard.
Through Empire’s Progeny, we will work together to make sense of this plurality of racial experience and understand how this changed. Near the end of the colonial period, we will witness the emergence of the modern sense of race: that is, the idea that people derive from fixed “races” that are geographically defined, reflect traits that are biologically based and immutable, and are knowable by how the person’s naked body appears. Apprehending the path to this and discern what came before it requires we attempt to put ourselves in the headspace of past individuals, to see the world as they did. When we ask, “What did Negro mean to urban free people of color and runaway slaves in Cuba?” we must resist the assumption that Negro meant anything like Black in the 20th and 21st centuries. We will find commonalities between historical and contemporary experience, and students are encouraged to seek and discuss such commonalities. But to understand the past and truly reflect on what it means for the present demands that we attend specifically to the differences. Therefore, Empire’s Progeny has been created to help students contemplate the past in its own terms.
A note on our own assumptions:
As we question the categories through which people in the past interpreted the world, we must also question our own. Let us lay out the most basic generalizations and stereotypes all of us have probably imbibed from school and popular culture:
- Indians were vulnerable people: weak, unable to defend themselves, and exploited everywhere. They were largely nomadic, “stone-aged” people overwhelmed by European technology. They lived close to Nature, with which they had a deep spiritual connection, until imperialism destroyed that way of life. Once Europeans arrived in the New World, it was a foregone conclusion that they would be decimated and/or extinguished.
- Spanish and Portuguese imperialists were rapacious and murderous, using their technological advantages to destroy Native American civilization. They were brutish, crude, and pompous overlords and were not intellectually curious people and could not imagine there was anything to learn from indigenous people or from Africans. These Iberians were superstitious Catholics, trapped in Medieval ideas about the world.
- Africans were powerless slaves. They never left the plantation and were kept in a state of abject deprivation. As a people, they were socially and spiritually crushed by the institution of slavery: their connections with their home cultures had been rent and they were incapable of developing a true social or political movement, in part because they lacked any political education or literacy. They were a broken people who soothed their souls with folk songs, but were otherwise without any capacity to change their world.
Again, these are the dominant stereotypes in our culture today. They are not 100% false – in fact, many colonists were greedy and rapacious; many indigenous peoples were swiftly annihilated; and many slaves were crushed by the institution of slavery. But not all. Perhaps not even most. While containing some truths, these stereotypes are also quite misleading. As we shall see in this course, some Spaniards recognized that they did not have overwhelming technological superiority, some indigenous people thrived with the presence of the European imperialists, and many Africans organized, achieved freedom, and became economically successful. Thus, while we question how others in the past saw the world, we must also accept that our own preconceptions may require considerable adjustment. | FINEWEB-EDU |
