67,960 | Hi there, I was wondering what is good question and what is bad question. I understand this is a subjective issue, but there must be some more details guidelines for that.
E.g. if someone gives a problem and asks: What might be a strategy to solve it?
I think that is an example of bad question, because someone hasn't applied any thought to solving the problem and just wants a solution, because this is their assignment or something. | 2010/10/18 | [

* having constraints you don't reveal until after gaining several answers ("actually I can't use anything after .NET 2.0", or "actually I don't have the source code for the library", or "actually my boss forbids us to use COM components", etc)

* pasting in dozens of lines of code that is not, in fact, the code that's having the problem - usually we can tell because what you pasted doesn't compile
* tag misuse and grammar/spelling/format, though generally I will just try to fix those so that someone will actually see the question and help you | "Please send me the codes" kind of questions.

We have a sulfur smell coming from the crawl space hot water heater, but the water smells fine coming from the attic hot water heater. Our cold water smells fine throughout the house, so we don't think the well water is the issue. The smell seems to be isolated to just the hot water heater in the crawl space.

If I understood it right, this last statement is made with the frequentist interpretation of probability in mind. However, **from a Bayesian probability perspective, why doesn't a 95% confidence interval contain the true parameter with 95% probability?** And if it doesn't, **what is wrong with the following reasoning?**
If I have a process that I know produces a correct answer 95% of the time then the probability of the next answer being correct is 0.95 (given that I don't have any extra information regarding the process). Similarly if someone shows me a confidence interval that is created by a process that will contain the true parameter 95% of the time, should I not be right in saying that it contains the true parameter with 0.95 probability, given what I know?
This question is similar to, but not the same as, [Why does a 95% CI not imply a 95% chance of containing the mean?](https://stats.stackexchange.com/questions/26450/why-does-a-95-ci-not-imply-a-95-chance-of-containing-the-mean) The answers to that question have been focusing on why a 95% CI does not imply a 95% chance of containing the mean from a frequentist perspective.

Two answers to this, the first being less helpful than the second
1. There are no confidence intervals in Bayesian statistics, so the question doesn't pertain.
2. In Bayesian statistics, there are however [credible intervals](http://en.wikipedia.org/wiki/Credible_interval), which play a similar role to confidence intervals. If you view priors and posteriors in Bayesian statistics as quantifying the reasonable *belief* that a parameter takes on certain values, then the answer to your question is yes, a 95% credible interval represents an interval within which a parameter is believed to lie with 95% probability.

Just the same as your process, the confidence interval guesses the correct answer with 95% probability. We're back in the world of classical statistics here: *before* you gather the data you can say there's a 95% probability of randomly gathered data determining the bounds of the confidence interval such that the mean is within the bounds.
With your process, *after* you've gotten your answer, you can't say based on whatever your guess was, that the true answer is the same as your guess with 95% probability. The guess is either right or wrong.
And just the same as your process, in the confidence interval case, after you've gotten the data and have an actual lower and upper bound, the mean is either within those bounds or it isn't, i.e. the chance of the mean being within those particular bounds is either 1 or 0. (Having skimmed the [question you refer to](https://stats.stackexchange.com/questions/26450/why-does-a-95-ci-not-imply-a-95-chance-of-containing-the-mean) it seems this is covered in much more detail there.)

> How to interpret a confidence interval given to you if you subscribe to a Bayesian view of probability.
>
>

There are a couple of ways of looking at this
1. Technically, the confidence interval hasn't been produced using a prior and Bayes theorem, so if you had a prior belief about the parameter concerned, there would be no way you could interpret the confidence interval in the Bayesian framework.
2. Another widely used and respected interpretation of confidence intervals is that they provide a "plausible range" of values for the parameter (see, e.g., [here](https://www.psychologicalscience.org/index.php/publications/observer/2010/april-10/understanding-confidence-intervals-cis-and-effect-size-estimation.html)). This de-emphasises the "repeated experiments" interpretation.
Moreover, under certain circumstances, notably when the prior is uninformative (doesn't tell you anything, e.g. flat), confidence intervals can produce exactly the same interval as a credible interval. In these circumstances, as a Bayesianist you could argue that had you taken the Bayesian route you would have gotten exactly the same results and you could interpret the confidence interval in the same way as a credible interval. | "**from a Bayesian probability perspective, why doesn't a 95% confidence interval contain the true parameter with 95% probability?** "
In Bayesian Statistics the parameter is not a unknown value, it is a Distribution. There is no interval containing the "true value", for a Bayesian point of view it does not even make sense. The parameter it's a random variable, you can perfectly know the probability of that value to be between *x\_inf* an *x\_max* if you know the distribuition. It's just a diferent mindset about the parameters, usually Bayesians used the median or average value of the distribuition of the parameter as a "estimate". There is not a confidence interval in Bayesian Statistics, something similar is called *credibility interval*.
Now from a frequencist point of view, the parameter is a "Fixed Value", not a random variable, can you really obtain probability interval (a 95% one) ? Remember that it's a fixed value not a random variable with a known distribution. Thats why you past the text **:"A confidence interval does not predict that the true value of the parameter has a particular probability of being in the confidence interval given the data actually obtained."**
The idea of repeating the experience over and over... is not Bayesian reasoning it's a Frequencist one. Imagine a real live experiment that you can only do once in your life time, can you/should you built that confidence interval (from the classical point of view )?.
But... in real life the results could get pretty close ( Bayesian vs Frequencist), maybe thats why It could be confusing. |

I would specify a bit differently standard hardware for hadoop
NameNode: High quality disk in mirror, 16 GB HDD.
Data Nodes: 16-24 GB RAM, Dual Quad or Dual six cores CPU, 4 to 6 1-2-3 SATA TB Drives.
I would also consider 10 GBit option. I think if it does not add more then 15% of cluster price - it makes sense. 15% came from rough estimation that data shipping from mappers to reducers takes about 15% of job time.
In your case I would be more willing to sacrifice disc sizes to save money, but not CPU/Memory/number of drives. | "extract relevant information from them using HIVE"
That is going to be a bit tricky since hive doesn't really do well with xml files.
you are going to want to build a parsing script in another language (ruby, python, perl, etc) that can parse the xml files and produce columnar output that you will load into hive. You can then use hive to call that external parsing script with a transform, or just use hadoopstreaming to prepare the data for hive.
Then it is just a matter of how fast you need the work done and how much space you need to hold the amount of data you are going to have.
you could build the process with a handful of files on a single system to test it. But you really need to have a better handle on your overall planned workload to properly scale your cluster. Minimum production cluster size would be 3 or 4 machines at a minimum, just for data redundancy. Beyond that, add nodes as necessary to meet your workload needs. |

27,167 | I'm currently fighting my way through the castle in Nethack. I was wearing 2 rings when I reached this level (a ring of protection and a ring of regeneration), and after a long battle both my rings are simply gone. Everything else I was wearing/carrying is still with me (including some other rings).
I don't remember taking them off, and I'm positive I didn't fight any nymphs or inccubus/succubus. I'm a dwarven valkyrie (though I'm pretty sure it doesn't influence anything).

482,553 | Looking at kernel.org the latest mainline release is 3.8. Zhe site also states the latest stable release is 3.7.9.
Now looking at <http://en.wikipedia.org/wiki/Linux_kernel> inside the version history table they state the latest stable version is 3.8. But a few lines up they write:
>
> ...Linus Torvalds makes the releases of new versions, also called the "vanilla" or "mainline" kernels, meaning that they contain the main, generic branch of development...
>
>
> ...
>
>
> In the current scheme, the main branch of development is not a traditional "stable" branch, instead it incorporates all kinds of changes, both the latest features as well as security and bug fixes.

So why do they call the latest mainline version 3.8 stable in the table, if it in fact isn't a stable one according to the quoted text of wikipedia? Or do they in fact mean linux-next is the main branch of development?
Which version should I install if I want the latest features but also great stability? (3.7.9?) | 2013/02/26 | [

] | "Latest feature" and "greatest stability" are not always tied together: with every major Linux release you'll get newest features but you'll probably get also regressions.
If you really don't want to use your distro's kernel, I would suggest to avoid the latest version and to opt for the previous one (e.g. 3.7.9) until some minor fixes are released (e.g. 3.8.1).
There's nothing stopping you from compiling/installing two different Linux versions (obviously you'll be able to run only one) | Whether or not a mainline kernel or even a stable kernel is **actually** stable largely depends on what features you're going to be using and on what platform.
For example, a particular kernel may well be bug-free on x86-64 but have issues under ARM, it all depends on how rigorously things were tested during the RC cycle.
With that said, the current state-of-play is that Greg KH is the main man with regard to stable kernels (although not by any means the only stable kernel maintainer) and he picks one kernel per year to maintain long-term.
Currently 3.4 is his long-term and all stable kernels since then are EOL'd as soon as he releases a stable for a new EOL.
If you are considering mainline, you would do well to follow Greg's patch series here: <http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git;a=summary>
A good barometer of a kernel's stability is examining the patches queued up for the latest stable - see firstly if any of those patches actually impact what you're using the kernel for and then see if those patches are also being applied to earlier versions anyway. |
12,764 | I've recently purchased a Hallicrafters S-120 -- 4-tube superhet receiver from the 1960s, continuous tuning from 540 kHz to 30 MHz, bandspread control, and a regenerative IF that doubles as a BFO for SSB and CW reception. Someone before me appears to have worked on the set, as the capacitors seem good (no hum, good reception for the antenna currently available).
What I've learned since receiving it, however, is that this set lacks the selectivity, stability, and fineness of tuning to make a good communications receiver; that is, it's for listening, rather than the listening side of two-way operation. While I have tuned in CW, digital, and SSB transmissions, the latter especially are hard to really clean up. AM transmissions in any band come in very readily and clearly, assuming they're above the noise floor.
With a limited budget, however, I'm looking for a better receiver for use when I get on the air (likely mainly CW, as a CW transmitter can be had fairly cheaply). I need to be able to tune across a band to search for calls, hear the spot tone to set the transmitter, have support for muting when the tranmitter key is down (or the ability add it), and by preference, I'd like it to use vacuum tubes.
What do I need to look for (that can be identified from photos and eBay listings that usually are intended to hide the faults of a piece) to distinguish "listening" radios from "communication" receivers? | 2019/02/06 | [

] | Since you plan to get licensed, I recommend that you purchase a transceiver, for two reasons.
1. There is no "modern" transmitter to pair with a communications-grade receiver.
2. A quick perusal of the classified ads reveals that, for similar receiver capability, the price of a receiver is not too different from the price of a transceiver.
The latest generation of ($$$!!) high-performance receivers appear to be "cut downs" of the same generation of transceiver. But, again, no mating transmitter is available.
If you still want to go the "separates" route, you will probably be relegated to the Drake "twins" or similar. Beware - the oscillators in these units may not be sufficiently stable to support digital modes beyond RTTY. If you want to operate FT8, for example, check with an expert to be sure you don't waste your time and treasure. | When looking at legacy receivers, a key differentiator is often general coverage (shortwave) vs amateur radio coverage. Most shortwave receivers lack the band spread, selectivity, filtering and demodulation features needed for practical use as a receiver for a QSO. Receivers targeted primarily at the ham radio community tend to have better overall features for ham use.
The next major differentiator is the superheterodyne architecture that represents the epitome of legacy receiver architectures.
Having selectable filters such as 3000 and 300 hertz can help to cut adjacent QRM.
A notch filter can help to cut an offending signal or noise.
If you have a computer (even a Raspberry Pi 3) and are willing to invest $200, you can get a state of the art software defined receiver. An example of such a receiver is the [Airspy HF+](https://airspy.com/airspy-hf-plus/). It is an amazing piece of hardware for the price and will give superior performance to many heterodyne receivers. It even allows you to operate it over the Internet.
For slightly more money, you can purchase an SDR transceiver such as the [HackRF One](https://wikipedia.org/wiki/HackRF_One). This will eliminate the need for frequency spotting and transmit/receive relays or PIN diode switching that you would need to accommodate with a separate transmitter.
If you are not familiar with SDR receivers, there is a [network](http://www.websdr.org) of them on the Internet that are free to use. |

By having a BSP with only convex geometry we guarantee that each leaf node will not have any ordering issues with the polygons contained in them, the BSP traversal algorithm itself can then produce a depth-sorted node list for you.
These days we have z-buffers so the need for convex leaf nodes isn't really that important, in some ways its better to render front-to-back also to take advantage of early-z optimisations on hardware. | Well, BSP is an application of a Binary Search Tree (BST)

My question is: If in the middle of my trip, I fly to Italy for a few days, and want to fly back to UK for a few more days before heading home, can I re-enter the UK?

Yes, though, as always, the immigration officer can deny entry if you do not convince him or her that you are a "genuine visitor."

There is no limit. You can reenter the UK as many times as you are able to while convincing the officer each time that you are a genuine visitor. This will become more difficult as the amount of time you've spent in the UK increases. It will also tend to be more difficult if the stated duration of your intended stay is longer or if your plans are more indeterminate.
If you want to stay for more than a couple of months, it's probably best to have your return flight booked when you arrive, have copies of (at least three months' worth of) your bank statements to show that you can support yourself without working, and evidence of your life in the US or other country of residence to show that you have something to return to. Say that you're essentially planning to stay until the date of your return flight, though you may mention the possibility of making some sort trips out and back in the meanwhile. If you're admitted on the first try, you're unlikely to be denied admission on subsequent arrivals between then and the date of your first flight.
The UK has a history of holding people to what they said at the border, so someone who was admitted for six months after saying they were planning to leave in three weeks, who subsequently decides to remain for much longer than three weeks, can be banned from the UK on a future visit on grounds of deception. It is therefore highly inadvisable to base the duration of your stay on the date of departure to Italy and then return after only a few days for another visit. That could easily be seen as an attempt to game the system. | What will make them itchy is if you are trying to
* seek employment in the UK. The #1 thing they look for there is *means of support*, i.e. They want to know you're not using up all your savings.
* live in the UK, as in, make that your primary residence.
* become a burden to social services, like public housing or healthcare.
Immigration's job is to assume you intend those things, then cheerfully accept evidence to the contrary.
They also like to see you have a plan (which includes not doing any of the above).
What you say when you reenter should match what you say on your first visit, because they remember. They dislike when what you say doesn't match actual facts, because that means they can't trust anything else you say. That makes it hard to accept your evidence. |

>
> An annual general meeting (commonly abbreviated as AGM, also known as the annual meeting) is a meeting that official bodies, and associations involving the general public (including companies with shareholders), are often required by law (or the constitution, charter, by-laws etc. governing the body) to hold. **An AGM is held every year to elect the board of directors and inform their members of previous and future activities.** It is an opportunity for the shareholders and partners to receive copies of the company's accounts as well as reviewing fiscal information for the past year and asking any questions regarding the directions the business will take in the future.

While it may sound as if only companies conduct AGMs, it has been appropriated for similar use by most structured bodies to represent important meetings held (annually) which require the presence of most of their members. [Extraordinary General Meetings](http://en.wikipedia.org/wiki/Extraordinary_general_meeting) or EGMs also exist. | Meetings that are held to inspire the membership or to increase their commitment are often called *[rallies](http://oxforddictionaries.com/definition/english/rally?region=uk&q=rally)* or *[revivals](http://www.merriam-webster.com/dictionary/revival)* (also *revival meeting*).
Meetings that are held for membership status or elections vary in what they are called depending on the periodicity. Many are yearly and are often called *annual meeting*. Sometimes they are called *membership meetings*, especially if the organization works throughout the year through its officers and committees, and the overall membership meets rarely. Alternatives are *general meetings* and *shareholder (stockholder) meetings*.
If the purpose of the meeting is specifically for selection of officers, they may simply be called *election meetings* or *elections*. |

] | Porbably not, Vulkan API is an Graphics Library much like OpenGL.
Where in Linux Ubuntu OpenGL is used for animation effects of the desktop in Unity and could be replaced with Vulkan for better performance.
But I don't think Windows will change it as they have their own DirectX Graphics Library and would be weird if they use something else instead their own software.
The most applications that are going to benefit from Vulkan are Games and other software that uses either 2D or 3D rendering.
It's very likely that most of the games are going to change to Vulkan because it's Cross-platform and therefore they will gain more users which equals to more profit.
Khronos (Vulkan API developers) are also bringing out tools that will largely port your application from OpenGL or DX12 to Vulkan therefore requiring less development/porting from the software developers side.
So...
Window creation, likely. (Although the code behind the window is CPU side, the library that draws the window on screen might be using Vulkan) - this differs greatly from which OS, distribution and version you are working on.
Mouse/keyboard events, no as this doesn't require any graphical calculations but CPU calculations. | Window (frames) are general desktop manager controls; you could display the vulkan app's content in the client area, otherwise vulkan would have to provide interfaces to the desktop manager for window creation (GUI library). Someone could simply create a device context (DC in windows, similar for the X server) then manage the "vulkan app" manually like a windowed game with no chrome (frameless), but this would be a great deal of work right now.

] | It won't. Window creation will be platform specific and an WSI extension will let you link the window to a renderable Image that you can push to the screen.
From information gleaned out of the presentations that have been given I expect that you will use a platform specific WSI Extension to create a Swapchain for your window.
Then each time you wish to push a frame to the screen you need to acquire a presentable image from the swapchain; render to it and then present it.

I am fortunate to live close to a Legoland and a LEGO retail store. However, I occasionally hear an employee say "Legos," and of course the (American) public uses "Legos" all the time.

Here is a link to their official policy statement:
<https://www.lego.com/en-us/legal/legal-notice/fair-play>
Relevant excerpts:
"**A Trademark must be Protected**
A trademark must be able to distinguish the goods of one company from those of another. If a trademark loses this ability, the owner may find that it can no longer prevent others from using the trademark. An owner must prevent the improper use of its trademarks to prevent the public from being deceived. This is why the LEGO Group is very active around the world in making sure that its trademarks are not misused."
"**Proper Use of the LEGO Trademark on a Web Site**
If the LEGO trademark is used at all, it should always be used as an adjective, not as a noun. For example, say "MODELS BUILT OF LEGO BRICKS". Never say "MODELS BUILT OF LEGOs". Also, the trademark should appear in the same typeface as the surrounding text and should not be isolated or set apart from the surrounding text. In other words, the trademarks should not be emphasized or highlighted. Finally, the LEGO trademark should always appear with a ® symbol each time it is used." |

] | The following sources helped me understand these landforms - hopefully they can help you too :)
From the [Miranda Shorebird Centre](https://www.miranda-shorebird.org.nz/natural-history/chenier-plains): The Miranda-Kaiaua cheniers are first formed as sand and cockle-shell bars on the foreshore or intertidal flats. The bars are then moved landward by wave action. Eventually the bars attain sufficient height to withstand such wave action.
From [NASA's Earth Observatory](https://earthobservatory.nasa.gov/images/78980/strandplain-coastal-peru): Strandplains are built by successive additions of beach sand, usually from some nearby source. Each ridge shows the position of a prior shoreline. | Pebbles and other mostly non-biological debris are heaped up on the beach by wave action. Then either the sea retreats or the land rises, and these features are left high and dry to become part of the landscape. An example of land rising may be found in Scotland, where relieved of the burden of ice a couple of kilometres thick, the land is still rising more than 10,000 years after the last ice age ended. Other phenomena may cause the land to rise, but the removal of an ice burden is a common one. |

] | 1. Easy: use an adjustable 3-terminal voltage regulator and connect the "adjust" pin to ground. The downside to this is that for every watt that goes to the motor, you'll burn up around 2.3 watts in the regulator. This means you'll need to pay attention to heat sinking, and you'll get really low system efficiency (but it'll work).
2. Medium-hard: Find a step-down converter, either a design to build or a module on ebay. If you find one that's current limited and nice and robust, and choose a current capability that's well above your motor's running current (because motors always consume more when starting than when running), it may work OK. You may have to do some experimenting, because by default step-down regulators don't play nicely with motors. Efficiency will be much better.
3. Hard: Use a half-bridge driver with PWM, with a duty cycle of around 30%. One downside is that if you're a newbie, you have no clue what I just said. An upside is that you have all the bits you need to make a speed control; you just need to be able to adjust the duty cycle from 0% to 30% | Search for:
* Step down converter
* Buck converter
* Switching converter
* DC-DC converter
Check that the input can be set to 5 V, and the output can be set to 1.5 V.
Some converters have fixed input/output voltages, others can be changed.
A ready made module also contains the necessary resistors/capacitors etc. |

The voltage divider allows us to have a 1.5v reference (200 kilo ohm resistor), I've chosen high value resistors in order to minimize as much the amount of power being lost. The comparator is there to quickly turn off and on the mosfet as soon as the load voltage increases over 1.5v and decreases to less than 1.5v. This very quick oscillation ensures that the voltage across the motor stays at 1.5v.

] | There is no rule or law that says that you have to try and checkmate in as few moves as possible and so there is no ethical requirement either.
In fact, if there are just a few pieces left on the board and you are very short of time it makes a lot of sense to take all the opponent's pieces as quickly as possible and only then worry about how you are going to checkmate.
Otherwise if you run out of time while your opponent still has some material left then you are going to lose on time. If your flag falls after you have taken all their pieces then you still get a draw. | If a football game was lopsided at halftime, wouldn't it be ethical to call the game?
Since chess has a resigning option, I don't consider any move as unethical. I consider an opponent who doesn't resign in a hopeless position as someone who deserves to be tortured, and it allows me to practice technique. So promote to all knights and practice the unusual mate. |

You're starting from a false premise — that the resolution tells you much about the image quality. The $6000 camera from your link has a 1/1.2"-format sensor, which has an area roughly 5× that in an iPhone. That larger area gives an inherent advantage.
As you note, this sensor is an industrial part, with [very detailed specifications](http://www.ccd.com/pdf/ccd_4000.pdf) readily available; among other things, if you need that technical information for a paper, you're not guessing. And while it has different characteristics from sensors in typical consumer cameras, it *is* a high end part.
You can see more on what can matter in a sensor at [What characteristics make a digital sensor good?](https://photo.stackexchange.com/questions/35861/what-characteristics-make-a-digital-sensor-good) — this alone is probably the key answer to your question.
But additionally, there are other distinguishing characteristics. For example, the sensor (and camera made around it) is available in a monochrome version, which means more per-pixel resolution if you don't care about color. And beyond image quality, the camera has features like gigabit ethernet output which are appropriate for a lab instrument; that
And, finally, the smartphone has a cheap lens built into it, a fixed limiting factor. This camera is an interchangeable lens system, making it much more versatile for whatever application.
Now, it may be possible that the consumer-device output will be just fine for what you need. In that case, awesome. But better quality more cheaply? No. | The difference is a higher reliability and compliance to different (industry) standards.
Say for example you are building automated assembly lines for other companies that at some point require computer vision.
If this assembly line fails and stops doing whatever it is supposed to do, the company that bought it from you will charge you by the minute (and call you as often).
It seems to be a good idea to use a camera that is built to last instead of some consumer product that is designed to be replaced in a few months with another version.
While they do not have any specifications online, I wouldn't be surprised if this industrial camera is dust and/or even splash proof.
The connector is Gigabit Ethernet, probably with a special connector to ensure dust/splash proving.
A lot of consumer laptops for example only come with 100 Ethernet these days, because people like the convenience of wireless connections. This is different in industry applications. It's not like factories set up wifi to share their important images.
Consumer electronics are so cheap because that is one of the most important goals in their design process. |

While name change by itself makes sense ("aiming to bury the FN name that has been associated with her father Jean-Marie since he co-founded the party in 1972"), the new name does not seem a happy choice.

] | Officially she wanted something more inviting, that would a) bring people together more - Hence Rassemblement National (National Gathering) vs Front National (National Front, as in it's a war) - and b) relieve the party of the stigma associated with its name (because it is widely perceived as racist and antisemite, because of the despicable reputation of its founder and his henchmen, etc.).
Unofficially it's anyone's guess.
There was a collaborationist French party during WW2, as you already pointed out, which was called Rassemblement National Populaire. Marine Le Pen's father, Jean-Marie Le Pen, is far too smart and cultivated to not have been aware of it. (The guy oozed intellect when debating, in contrast with his daughter who oozes unsophistication. He could possibly have risen to power in the 90s or 00s had he not been a certified racist and antisemite.)
At any rate, fast forward to the 1965 presidential election. An extreme right wing lawyer then campaigned under the name Rassemblement National. Surely he was fully aware of the backstory. His campaign manager, incidentally, was no other than Jean-Marie Le Pen.
Jean-Marie Le Pen then used the name again during the 1985 and 1986 elections as has been widely reported in French press.
And that's to say nothing of the other polemic that revolves around there already being a (Gaullist) RN party around.
The point I'm trying to get at is that, there's an official reason but it certainly seems like there's some [dog whistling](https://en.wikipedia.org/wiki/Dog-whistle_politics) involved too. Or maybe it's just woeful incompetence and lack of historical references among the FN/RN's current ruling team. | A few elements in addition to @Denis de Bernardy's answer:
1. *Rassemblement* (Rally) is common in French parties' name. For example, [Wikipedia](https://www.wikiwand.com/fr/Liste_des_partis_et_mouvements_politiques_fran%C3%A7ais) lists 22 active parties containing the word in their name. For example, the Republicans used to be called *Rassemblement pour la Republique* (Rally for the Republic) from 1976 to 2002.
2. Marine Le Pen quite successfully used the word *Rassemblement* in the past. She branded the name *Rassemblement Bleu Marine* (Navy Blue Rally, a word play on her name) during local and national elections when she was at the head of the *Front National*. Many candidates for local elections campaigned under that name in place of putting the *Front National* name on their flyer, as it was meant to be a departure from the bad image of the party and a sign of renewal and modernism. |

] | Disassemble
===========
It will be easier to work with if you can take the furniture apart, or at least break it down in to smaller pieces. If you can't take it apart, you'll still want to remove any doors or drawers.
Sand
====
You'll want to sand the surfaces that will be painted, with 220 grit sand paper. Be careful not to sand too much, you don't want to sand completely through the veneer. You're just looking to remove the protective coating, and scuff up the surface a bit.
Wipe away the dust
==================
Wipe the surfaces down with a [Tack cloth](http://en.wikipedia.org/wiki/Tack_cloth) to remove all the dust.
Prime
=====
Prime the surfaces with a primer designed for laminate, or "glossy surfaces". [Zinsser Bulls Eye 1-2-3 Primer/Sealer](http://www.thepaintstore.com/Zinsser_Bulls_Eye_1_2_3_Primer_Sealer_p/02004.htm) is one such primer, though somebody in the paint department at your local hardware store may be able recommend a better/different one.
Wait
====
You'll want to wait the full cure time specified in the instructions on the primer, before you start painting.
Paint
=====
Apply 2 coats of paint (waiting the specified time between coats), with a foam brush and/or roller. You can use any type of brush you want, but a regular brush might leave streaks while a regular roller may leave an undesired texture.
Seal
====
Once the paint has fully dried, you can apply a [polyurethane](http://en.wikipedia.org/wiki/Polyurethane) to help protect the finish. Apply 2-3 coats with a foam or soft bristle brush, sanding between coats with 220 or 320 grit sand paper (See [What grit sandpaper should I use between coats of poly?](https://diy.stackexchange.com/q/4469/33)).
Put it back together
====================
Reassemble the furniture, and touch up any spots damaged during assembly. | I'd suggest talking to a dedicated paint store specialist. I imagine you can but it's going to take some heavy duty primer or possibly an epoxy based paint.
Off the top of my head, one specific product that might fit the bill is a new-ish 'kitchen counter refinisher' that I've seen pop-up lately at the home improvement stores. There appear to be various brands. A quick google search turns up several. It appears that many of them are using an epoxy based system. I have no idea the cost, so it may very well be cost prohibitive compared to the original cost of the furniture. |

] | The location of the North Pole is 21.18 RA, 52.89 North. There is no "North Star" located there, although it is about half-way between Deneb and Alderamin. ([Source](http://earthsky.org/space/mars-north-south-star)). In the sourthern sky, Kappa Velorum is a good South Pole Star. Here's also a few screenshots as to what the poles would look like:
[Mars North Pole](http://www.eknent.com/etc/mars_sp.png):
[Mars South Pole](http://www.eknent.com/etc/mars_sp.png):
I've also added a bit of video showing how these stars will appear in the following video: | Martians could imagine a line formed by [Deneb](https://en.wikipedia.org/wiki/Deneb) and [Sadr](https://en.wikipedia.org/wiki/Gamma_Cygni), which have [apparent magnitudes](https://en.wikipedia.org/wiki/Apparent_magnitude) of 1.21–1.29 and 2.23 respectively (lower is brighter), compared with Polaris which [varies](https://en.wikipedia.org/wiki/List_of_brightest_stars) between 1.86–2.13. This would get them a little less than 3° away from true north (compared to <0.5° for Polaris on Earth).
They could also take the midpoint between Deneb and [Alderamin](https://en.wikipedia.org/wiki/Alpha_Cephei), but it's fainter, with an apparent visual magnitude of 2.5141. If you extend the midpoint by one seventh of the total distance between Deneb and Alderamin, you'll get pretty close to the North Pole.
[](https://i.stack.imgur.com/g5Cxq.png)
Yellow is the distance between Sadr (the star above Deneb in the [Cygnus](https://en.wikipedia.org/wiki/Cygnus_(constellation)) constellation) and Deneb extended from Deneb. Cyan is a line from Deneb to Alderamin, with a line 1/7th of the distance extending from its midpoint; accurately eyeballing a seventh and figuring out which way the line should extend is left as an exercise for the Martians.
---
After some stargazing, I found Alderamin very obvious and on reflection, knowing that Sadr to Deneb points to the Martian north is only useful for remembering which way to extend the seventh (though you can just remember that Cygnus points to the North).
Cygnus is pretty easy to find becuase it's in the Milky Way, so you just follow that large cloudy patch in the sky until you find it, although there's a similar looking constelation, [Aquila](https://en.wikipedia.org/wiki/Aquila_(constellation)) which also looks like a stick figure but smaller and with the arms raised at a higher angle (turns out it's actually supposed to be an eagle).
The other approximate way to find it is the same way you [find Polaris from the Big Dipper](https://en.wikipedia.org/wiki/Polaris#/media/File:Ursa_Major_-_Ursa_Minor_-_Polaris.jpg) using its front two stars, you just have to go 2-3 times as far and you end up pretty far away, but in the general area. Orion's belt also points in that general direction, but it's far away.
[Cassiopeia](https://en.wikipedia.org/wiki/Cassiopeia_(constellation)) (looks like the letter W) is the most obvious nearby constellation. Also the star [Vega](https://en.wikipedia.org/wiki/Vega) is close by and very bright. |

] | Well, to me your answer does look like an answer. It would probably fit the "low quality" criteria - and I would add a comment stating somethine like "please avoid a simple one-line answer. We are looking for more expanded answers".
It's further likely that your answer would get downvotes, exactly because it's a one-liner whereas there is a clear opportunity to provide more details (as has been done in the accepted answer). Hence, converting it into comment, in my opinion, saves you from receiving downvotes.
This may not answer your question of why it was converted - that's up to the moderator who did that to explain though - but I'm suggesting some possibilities. | The reasons it was converted to a comment are following:
* It does not adds anything new to the answers that are already there.
* When answer is that short it most probably will lead for some discussions.
As an extreme case think of an answer as short as just "Да". This could be valid but if you won't take some effort and elaborate it very likely that somebody will add a comment "Почему", somebody else will add comment "Нет" etc. This hardly will make the answer neither more valuable nor more readable.
* It is still a valuable note which would be nice to see right under the question. |
5,486 | Just last night the heat bed stopped working. It was fine up to 75 % of the print, then when it was done the bed was not on anymore. The display said it was set to 50 °C, but it was at 18 °C. I did try moving the pins, and that is not loose (very simple thing to try).
I want to know what could have happened and what to look for when I try to fix the heat bed.
Please note: I do have a multi-meter. I do not use a MOSFET (I do have plans to install on)
Upon further investigation, I tested the mother board for any voltage were the bed hooks up and there is nothing. I had the printer trying to heat the bed when I was testing. But the thermistor is working, when I unhooked the connection the thermistor went to 0 °C, when plugged in it went to 18 °C.
Is it the motherboard? How can I fix this knowing no power is being supplied to the bed from the motherboard? Do I need a new motherboard? | 2018/02/13 | [

] | This is a shot in the dark, but the vast majority of problems with a heating bed stopping to work is usually at the cables/connectors interface.
This is because in printers like the A6, the cable/connector is subject to constant mechanical stress, and - since [metal fatigue](https://en.m.wikipedia.org/wiki/Metal_Fatigue) is a thing - either the solder or the cable core cracks.
You should make good use of your tester to verify the integrity of the circuit in the bed and if it is not toasted you should be able to just repair the connection.
For many printers there exist "strain relief mods" to prevent this type of failure to happen. The first one showing up for the A6 is [a full chain](https://www.thingiverse.com/thing:2020947), but normally is enough the have a small enclosure for the connector like [this one](https://www.thingiverse.com/thing:2186203) for the CR-10. | The bed stopped working yesterday. I used the multimeter on the bed plug. The bed heater reads 1.7-1.8 Ohm.
There was no 12 V supplied from the mainboard and I read its terminals. There were 12 V there. I tightened the screws and the plug received 12 V.
The bed heated for one print. Today I repeated the troubleshooting and found that the bed plug still had 12 V. When I pulled it, the Red terminal was burnt and melted into the plug. After cleaning it by inserting and removing it several times, the bed started working again. The Red and Black wires are hot to touch though.
This is the troubleshooting procedure one should follow. What remains to be confirmed is whether the resistance of the bed heater is correct; 1.8 Ohm at 12 V is about 80 W. Sounds about right, so the wires should not overheat.
I suspected a possibility of the shorting to the aluminum bed, but then the bed would be heated only in some areas, but mine is heated evenly across the entire surface area.
Edit: For now I ended up cutting the Red wire's terminal from the plug and soldering the wire directly to the bed. I might order the new bed harness from Anet, or not. |

I am not a Zerg player so I have no opinions on this. | If you have multiple hatcheries in an area then tenfour's method won't be very effective. You can however double tap on your queen hotkey to centre the map on her, do your larvae business, and then double tap on your army hotkey to get back into the action.
However for expansions, the mini-map method works fine. |

This method though requires clicking on your minimap very accurately, if you don't then you're stuck with the targeting cross-hair for the larva inject spell. |
