* No legitimate bank is going to ask you to make payments to a bitcoin wallet
You could certainly spend time and effort looking up a bank with the regulators of whatever country the bank operates in. And if there is a legitimate bank by that name, then spend time and effort trying to determine whether the people you're talking to actually associated with that legitimate bank.

**Also all banks must be registered.** [For example, here is the list of banks and financial institutions in my country.](http://www.osfi-bsif.gc.ca/Eng/wt-ow/Pages/wwr-er.aspx)
If either of the above are not true then the "bank" is unquestionably a scam. |

But given the hallmarks of a scam, it isn't worth the effort. | The most simplest way to check if a bank is legit, is to search your governments directory of registered banks.
For example;
1. [Hong Kong's Government's list of registered/licensed banks](https://www.hkma.gov.hk/media/eng/doc/key-functions/banking-stability/banking-policy-and-supervision/list_of_lb.xls)
2. [India's official list of registered/licensed banks](https://m.rbi.org.in/scripts/bs_viewcontent.aspx?Id=3657)
These can be easily found with a google search like "India list of registered banks", and find the government supplied site
Another effective way to find out if a bank is legit is look for mistakes in English/spelling/grammar. Often these fake sites are made in a rush by non-native speakers of English. Plus, real banks will invest a lot of money in making sure that their English is flawless. (Applies to other languages as well, e.g. if your bank language is Spanish, French etc etc) |
137,529 | I've been trying to find out what skills Drow have options to be proficient in, typically a race offers a few choices but only allows you to pick two, and your class gives you two more, followed by your background giving you 1 or 2 more correct? But I've looked at numerous sites trying to find out what skill choices Drow offer and have found none. Is it an error or do they really have no skill proficiencies?

] | The Drow race does not confer any skill proficiency
===================================================
I looked up my [PHB on page 24](https://www.dndbeyond.com/characters/races/elf#DarkElfDrow), and the only proficiencies gained by Drow are rapiers, shortswords, and hand crossbows, in addition to Perception given by being an Elf (of any kind).
Most races do not confer skill proficiencies, and no option of selecting among them
-----------------------------------------------------------------------------------
Some races give proficiency in certain tools (like Rock Gnomes), or armor (like Mountain Dwarves), or even skills (like Elves), but it is not an automatic thing every race does.
The only races that I've seen that give a choice of skills are Half-Elf which has Skill Versatility, you gain proficiency in two skills of your choice,
and a variant trait for Human, which gives 1 skill of your choice.
Classes let you choose (usually 2) skills to be proficient in
-------------------------------------------------------------
Based on your class you can choose a number of skills to be proficient in, from a provided list. You may be confusing this with what you get from your race.
Backgrounds also give 2 skill proficiencies, but these are determined by the background you choose and can't be mixed or changed (although you can make a custom background to choose the skills you want). | [Drow](https://www.dndbeyond.com/characters/races/elf#DarkElfDrow) get the following:
Being an Elf gives them the following Skill proficiency (PHB, 23):
>
> **Keen Senses**
>
>
> You have proficiency in the Perception skill.
>
>
>
And being Drow gives you the following weapon proficiencies (PHB, 24):
>
> **Drow Weapon Training**
>
>
> You have proficiency with rapiers, shortswords, and hand crossbows.
>
>
>
Because there other benefits for being Elf and Drow-Elf, no other skill profiencies are provided.
Skills generally come from Class and Background
-----------------------------------------------
Each **[Class](https://www.dndbeyond.com/compendium/rules/basic-rules/classes#ClassesSummary)** will give you an option to select Skills. These are listed under the **Class Features** section and will list what skills are available and how many you can choose.
Each **[Background](https://www.dndbeyond.com/compendium/rules/basic-rules/personality-and-background#Backgrounds)** will also give you skill choices, and you can always choose to do a [custom background](https://www.dndbeyond.com/compendium/rules/basic-rules/personality-and-background#CustomizingaBackground), allowing you greater freedom in skills/proficiencies/languages. |

] | When you share, what you are sharing is your library.
You can play any game the owner has, but you can't do it while he is playing any other game. No matter the video game, while he is playing something, you cannot play anything from his library.
I have my library shared with my girlfriend and these are some of the checks we did:
* It does not matter if the other person is offline - you can play the shared games as long as you have an internet connection;
* You can only play if your friend's library is free. This means that neither the owner or anyone else is using that library at that time;
* If someone else has shared the library and starts playing before you, you'll have to wait until that person stops playing;
* Even if you or someone else is playing, if the owner of the library starts playing, he will "eject" you from the shared game after 5 minutes;
* You can not play any offline game that is not yours, because Steam verifies whether or not you have access to the game, offline or not;
* All the DLC are also shared (unless the person borrowing only owns the base game). | **tl,dr: there is no way for you to access your friend's shared library while he is playing Dota2**
An online Steam library can only be in use by any 1 person at a time (in use = any game inside that library is running).
You cannot access someone else's shared libraries while in offline mode yourself.
However, if the owner of the library boots Steam in offline mode, the Steam servers have no way of knowing that he is in fact playing and hence, the owner and 1 other person (so 2 in total) can use his library (note that this is useless in your case since Dota2 is an online game so offline mode is not an option).
Only thing I have not tested since the friendlist overhaul is, whether logging off the friend system is enough to count as offline, or if you still have to completely boot Steam in offline mode (which I suppose).
**Edit:**
Apparantly the owner can no longer switch to offline mode in order to share his library while playing, see the comments by Joachim for more details. |

Because they ARE high pressure.
Why?
Because, in IT terms, they do not know what they are doing, or more precisely, they do not follow good development practices, because someone outside of IT is in charge.
One of the problems we software developers have is that software is not a tangible, physical object. To non-IT people it is this wooly, obscure thing that just exists inside their computer.
But because they cannot touch it, they do not appreciate the intricacies that go into building good software.
So when you get these types of people "driving the bus", you soon get comments like:
* just build it
* we need it in 1 month
* we don't need testers
They don't get it. | It doesn't mean that much in most cases. After all, would a company really say that they have a work environment where their philosophy is "[Mañana](http://en.wiktionary.org/wiki/ma%C3%B1ana)". It's one of those standard clichés that get throw into job listings by HR people, just like saying they want "highly motivated people" and that they offer "a competitive salary with a complete benefit package".
You'll need to find out from your interview exactly what kind of pressure a job is likely to have, if it's just HR-speak or if they really have time critical work that has to be done. For example, you may find out that they do a lot of client driven or time critical projects that need to be done very quickly, such as advertising campaigns or event planning. Or, you may find that the organization is populated with bullies and jerks who create ugly pressure. Or, it may be just HR-BS and the environment is a pretty typical development shop. |

] | Example high pressure job: High frequency algorithmic trading. A software engineer friend of mine is working for a trading shop. Huge stress, huge pressure. All deadlines are "right now". Everything is shipped to production on the day it's written. Even a few minute delay could cost the company millions. Not many people can handle an environment like this. If you can do it, expect a 50-100% higher salary than industry standard at your level + end-of-year bonus based on % of your algos' profits. It's super high-risk, high-pressure, high reward. It has nothing to do with unrealistic deadlines or lacking management, and everything to do with your ability to handle the pressure. (And traders swearing at your face as their P&L goes down the crapper that day.)
Other examples:
* Jobs where producing the kind of software with high-requirements for dependendability:
+ medical software,
+ embedded software.
* Jobs where deliverables (and failures) would have:
+ a direct and large impact on people,
+ a direct and large impact on the company's image.
Alternatively, it's not necessarily just code for "[we're under-resourced and have unrealistically aggressive deadlines](https://softwareengineering.stackexchange.com/a/137521/3631)", but also possibly code for "your responsibility makes you an expendable liability if anything goes awry". | A startup that rushes to the market must struggle to be faster than the competition. For such a company, it makes sense to create a high pressure work environment, since being there two months before others working on the same problem might make the difference between being the next facebook and being, well, a too-little-too-late service nobody remembers. Working in such a company might make you rich quickly, through stock options.
For a well established software company, constantly high pressure is a sign of bad management and/or greedy owners and therefore a red flag. |

Thanks to the add-on Proportional Dimensions To New Size, the problem of proportional scaling (with mm or inch) of one object has been solved.
Now, problem is when we want to resize multiple selected objects to an exact dimension (mm, inch) without having to merge them.
So far I have found that with the help of “Proportional Dimensions To New Size” add-on I can achieve that simple task with a lot of extra work…
For example, we have two objects that we want to enlarge proportionally by setting the desired height.
* select the objects that we want to enlarge proportionally
* OBJECT > SNAP > CURSOR TO SELECTED
* OBJECT > SET ORIGIN > ORIGIN TO 3D CURSOR
* OBJECT > DUPLICATE OBJECTS
* move the duplicated objects aside
* merge duplicated objects, OBJECT > JOIN
* we select the original objects and the duplicated object, for the active object we mark the duplicated
* in field Z at “Proportional Dimensions” panel type the desired height
We got our two objects proportionally enlarged to the desired height, we can now delete the duplicated.

Does anyone know of an easier way? | Denis was on the right track, but you may need a little more information. Let's say you want to scale Y by 2.5. If you want the other dimensions to scale proportionately, then they should also be scaled by 2.5. So, with the object selected in Object mode, just press [S] [2] [.] [5] [Enter]. That's it! |

I've connected the Arduino's GND to the negative lane (word?) on the breadboard (for clarity modeled by SW1 in the circuit diagram).
I noticed that if I don't do this, it does not work (no voltage at the gate) - why do I need to use the same ground?

Another thing, put the common lead of the power supply as close as possible to MOSFET return path, ideally in the pin next to it. That will keep the return current off your ground bus, and that is known to make microcontrollers behave in undesirable ways. It may not be a problem for this circuit since its only 120mA, but it's a good habit. | It seams strange to me to connect the Gate to a constant 5V pin. Shoudn't this be on a IO-pin?
I would add a diode to the valve in order to prevent voltage peaks when turning the FET off.

The idea here is that the Truth lies beyond such simplistic categories, and to be in touch with Truth we must cease our tendency to cling to flat/singlesided explanations. In my own words, reality is complex, "quantum", "multidimmensional", and our habitual attempts to "flatten" it constantly lead to failed expectations and to suffering.

Srenika was concerned to find a true self, in other words, the Tathagata. Nagarjuna relates that Srenika originally took the person as one lump, and that therefore the Buddha asked him about its elements. He had also heard people speak of the “I” in two ways, as identical with the five skandhas, and as different from them. The skandhas are multiple, and the I is one – so they cannot be identical. The self would be born and perish as the skandhas do, and it would not be independent of causes and conditions – thus it would not be the true self. Therefore, how can something outside the five skandhas have the character of “I” or “self”? As Nagarjuna puts it, “Srenika’s second act of faith consisted in that, when he had heard that the Buddha denied the self, and said that from the beginning there was none, he accepted the fact that, because there is no self, the dharmas have no support, and are like a dream, a mirage, nonapprehensible.

So one might assume this as a canonical explaination of what is that annihilation with which Vacchagotta could've sided had the Buddha declared that there is no self [that persists through the breakup of the body] and it is imo natural to assume that this is the implied meaning because it was spoken as in opposition to eternalism which was favored by the Brahmins of that time who held that the is an element of true self that persists connecting one birth to another.
The Buddha taught neither of the two extremes. He taught that there are consequences of actions to be experienced as pleasant & unplesant feelings after the breakup of the body but he also taught that the consciousness is such that it arises as one thing and ceases as another so the consciousness which can be grasped with wrong view to be personal for this or that person might arise as that and ceases as that which can be grasped with wrong view to be that of another.
He taught that the existence of a particular being can not be pinned down as a truth or reality much like you can't pin your name as truth & reality. He taught that it is said that the notion of a being is just a matter of thinking about the world. Neither the meat&bone body nor intellect are a person or a person's name in & by themselves but a person is said to not be without, therefore speaking of a "person" or a person's "name" is entirely a matter of speech & agreed upon assertions as it's existence can not be pinned down as anything other than an idea or its expression neither in this life nor the next.
He understood that which is a truth & reality and explained it's conditional dependency. There was no self among those elements, there were ideas and some unfortunate confusion about the content of ideas being as real as the truth of ideation there but there was no self other than an object ideation coming into play to cause all kinds of delusion. |

] | The sutta is not about the not-self (**anatta**) doctrine. The [Pali](https://suttacentral.net/pi/sn44.10) is:
>
> Ekamantaṃ nisinno kho vacchagotto paribbājako bhagavantaṃ etadavoca:

The confused Vacchagotta basically asks the questions:
(i) 'Does my self exist (*atthattā*)?'; and
(ii) 'Does my self not exist (*natthattā*)?'.
Please notice how Vacchagotta did not ask about 'anatta' (not-self) and how it was Vacchagotta who used the words 'atthattā' & 'natthattā' rather than the Buddha. In other words, the discussion is not about the doctrine & terminology of the Buddha. The sutta is about the doctrine of Vacchagotta.
Since both of Vacchagotta's questions contained the idea of 'my self', they were illogical questions; thus the Buddha did not answer.
For example, if Vacchagotta asked: (i) is there a real self; or (ii) is there a self among the five aggregates; the Buddha could have answered. But Vacchagotta essentially asked: (i) is the self a self & (ii) is the self not a self; which was illogical. | In Mahayana, Vacchagotta (also known as Shrenika, Srenika or Seniya The Wanderer) is considered an important character, in conversations with whom Buddha illustrates the main principle of Madhyamaka - emptiness of all mental constructs, liberation by wisdom that comes from careful analysis of dharmas, direct vision into nature of things beyond either existence no nonexistence.

The confused Vacchagotta basically asks the questions:
(i) 'Does my self exist (*atthattā*)?'; and
(ii) 'Does my self not exist (*natthattā*)?'.
Please notice how Vacchagotta did not ask about 'anatta' (not-self) and how it was Vacchagotta who used the words 'atthattā' & 'natthattā' rather than the Buddha. In other words, the discussion is not about the doctrine & terminology of the Buddha. The sutta is about the doctrine of Vacchagotta.
Since both of Vacchagotta's questions contained the idea of 'my self', they were illogical questions; thus the Buddha did not answer.
For example, if Vacchagotta asked: (i) is there a real self; or (ii) is there a self among the five aggregates; the Buddha could have answered. But Vacchagotta essentially asked: (i) is the self a self & (ii) is the self not a self; which was illogical. | There are other Sutta which help understand this.

So one might assume this as a canonical explaination of what is that annihilation with which Vacchagotta could've sided had the Buddha declared that there is no self [that persists through the breakup of the body] and it is imo natural to assume that this is the implied meaning because it was spoken as in opposition to eternalism which was favored by the Brahmins of that time who held that the is an element of true self that persists connecting one birth to another.
The Buddha taught neither of the two extremes. He taught that there are consequences of actions to be experienced as pleasant & unplesant feelings after the breakup of the body but he also taught that the consciousness is such that it arises as one thing and ceases as another so the consciousness which can be grasped with wrong view to be personal for this or that person might arise as that and ceases as that which can be grasped with wrong view to be that of another.
He taught that the existence of a particular being can not be pinned down as a truth or reality much like you can't pin your name as truth & reality. He taught that it is said that the notion of a being is just a matter of thinking about the world. Neither the meat&bone body nor intellect are a person or a person's name in & by themselves but a person is said to not be without, therefore speaking of a "person" or a person's "name" is entirely a matter of speech & agreed upon assertions as it's existence can not be pinned down as anything other than an idea or its expression neither in this life nor the next.
He understood that which is a truth & reality and explained it's conditional dependency. There was no self among those elements, there were ideas and some unfortunate confusion about the content of ideas being as real as the truth of ideation there but there was no self other than an object ideation coming into play to cause all kinds of delusion. |

] | In Mahayana, Vacchagotta (also known as Shrenika, Srenika or Seniya The Wanderer) is considered an important character, in conversations with whom Buddha illustrates the main principle of Madhyamaka - emptiness of all mental constructs, liberation by wisdom that comes from careful analysis of dharmas, direct vision into nature of things beyond either existence no nonexistence. The idea here is that the Truth lies beyond such simplistic categories, and to be in touch with Truth we must cease our tendency to cling to flat/singlesided explanations. In my own words, reality is complex, "quantum", "multidimmensional", and our habitual attempts to "flatten" it constantly lead to failed expectations and to suffering. Enlightened mind can see reality as it is, unhindered by conceptual limitations, and so always stays in touch with "tatha" - the way things really are.
In Pali Canon, Vacchagotta is mentioned in a number of suttas, all going around similar topics, e.g.:
* [MN 72 Aggi-Vacchagotta Sutta](https://www.accesstoinsight.org/tipitaka/mn/mn.072.than.html)
* [SN 44.7 Moggallana Sutta](https://www.accesstoinsight.org/tipitaka/sn/sn44/sn44.007.than.html)
* [SN 44.8 Vacchagotta Sutta](https://www.accesstoinsight.org/tipitaka/sn/sn44/sn44.008.than.html)
* [SN 44.9 Kutuhalasala Sutta](https://www.accesstoinsight.org/tipitaka/sn/sn44/sn44.009.than.html)
* [SN 44.10 Ananda Sutta](https://www.accesstoinsight.org/tipitaka/sn/sn44/sn44.010.than.html)
* [SN 44.11 Sabhiya Sutta](https://www.accesstoinsight.org/tipitaka/sn/sn44/sn44.011.than.html)
In Chinese Agamas, there is one long sutra known as [SA 105 Discourse to Seniya](https://www.buddhismuskunde.uni-hamburg.de/pdf/5-personen/analayo/translations/sa05.pdf) that collects these ideas in single place.
Here I will paste explanation of Shrenika's role Eduard Conze gave in his introduction to [The Large Sutra On Perfect Wisdom](http://lirs.ru/lib/conze/The_Large_Sutra_On_Perfect_Wisdom,Conze,1975.pdf), commenting on the following verse in [Ratnagunasamcayagatha](http://www.abuddhistlibrary.com/Buddhism/C%20-%20Zen/Sutras/The%20Ratnagunasamcayagatha/The%20Ratnaguna-samcayagatha%20II.htm):
>
> As venerable Shrenika the wandering beggar,
>
> Understanding acquired, without grasping the skandhas,
>
> Just so a bodhisattva, intuits real nature of things (dharmas).
>
> And does not seek cessation but abides in wisdom.
>
>
>
Conze says:
>
> Srenika the Wanderer is, according to Nagarjuna, the Srenika Vatsagotra, who in the Pali texts is simply called Vacchagotta. A number of his conversations with the Buddha are recorded. They are scattered through the Pali Canon, but combined into one section in the Samyuktagama of the Sarvastivadins. The text refers here to a [Sutra](https://www.buddhismuskunde.uni-hamburg.de/pdf/5-personen/analayo/translations/sa05.pdf) which, according to Nagarjuna, discussed “Srenika the Believer” and at the same time, according to the Vibhasha and Nagarjuna, preached the emptiness of all dharmas. Since Subhuti’s argument is difficult (*here Conze refers to Chapter 8 of [The Large Sutra On Perfect Wisdom](http://lirs.ru/lib/conze/The_Large_Sutra_On_Perfect_Wisdom,Conze,1975.pdf), "How the irreversible Bodhisattva views things" - which is a fascinating read in itself -- AV*), and since we are inclined to lean on signs, and do not see how we can have faith without a sign, “Subhuti here takes as his witness the Little Vehicle where it speaks of the emptiness of dharmas, How could those who practice the great vehicle not believe in it?”
>
>
> Srenika showed “faith”, first, in that he believed that the Buddha could help him to find the path, and, second, in that he was willing to accept the Tathagata in spite of the fact that he could not be related to any of the skandhas, i.e. to form, etc. He entered into a “cognition with a limited scope” which, according to Haribhadra means that it was directed to the absence of a self in persons, and not also in dharmas). Srenika was concerned to find a true self, in other words, the Tathagata. Nagarjuna relates that Srenika originally took the person as one lump, and that therefore the Buddha asked him about its elements. He had also heard people speak of the “I” in two ways, as identical with the five skandhas, and as different from them. The skandhas are multiple, and the I is one – so they cannot be identical. The self would be born and perish as the skandhas do, and it would not be independent of causes and conditions – thus it would not be the true self. Therefore, how can something outside the five skandhas have the character of “I” or “self”? As Nagarjuna puts it, “Srenika’s second act of faith consisted in that, when he had heard that the Buddha denied the self, and said that from the beginning there was none, he accepted the fact that, because there is no self, the dharmas have no support, and are like a dream, a mirage, nonapprehensible. Having obtained power of faith, he entered into the true mark of dharmas, and did not mistake form for the Tathagata”
>
>
> Srenika “did not take hold of form, etc.” The Buddha asked him: “Do you regard the Tathagata as form?” “No.” “As in form?” “No.” “As outside form?” “No.” “As the absence of form?” “No.” “When, under all these aspects, you do not see the Tathagata, should you doubt, and say: What is there fixed and definite in the Buddhas’ doctrine?” “No.” Srenika then won the path, and became an Arhat. This is how Nagarjuna recounts [the Sutra](https://www.buddhismuskunde.uni-hamburg.de/pdf/5-personen/analayo/translations/sa05.pdf).

] | Yes definaltely you can use Laravel since its developed using php
Laravel has lots of features it will make your work faster .
[](https://i.stack.imgur.com/HvvVN.jpg)
Image from
<https://coderseye.com/best-php-frameworks-for-web-developers/>
features of PHP Laravel Framework that make it popular among developers and businesses alike:
1. **Template Engine**
Laravel framework is highly acknowledged for its inbuilt lightweight templates that help you create amazing layouts using dynamic content seeding. In addition to this, it has multiple widgets incorporating CSS and JS code with solid structures. The templates of laravel frameworks are innovatively designed to create a simple layout with distinctive sections.
2. **Artisan**
Laravel offers a built-in tool for command line known as Artisan which allows performing the majority of those tedious and repetitive programming tasks that many developers avoid performing manually. These artisans can also be utilized to create the database structure, a skeleton code, and build their migration that becomes pretty easy-to-manage the database system. In addition, it can be interlaced to generate the basic MVC files right away through the command-line and manage those assets and their respective configurations. Artisan even helps developers to create their own commands and do convenient things with it.
3. **Eloquent ORM (object-relational mapping)**
Laravel framework offers the Eloquent ORM that includes a simple PHP Active Record implementation. It lets the web app developers issue database queries with PHP syntax rather than writing SQL code. Every table in the database possesses a corresponding Model through which the developer interacts with said table. An ORM is relatively faster than all other PHP frameworks.
4. **Libraries & Modular:**
Laravel is also popular due to its Object Oriented libraries as well as many other pre-installed libraries. These pre-installed libraries are not found in any other PHP frameworks. One of the preinstalled libraries is an Authentication library which is easy-to-implement and has many latest features, such as checking active users, Bcrypt hashing, password reset, CSRF (Cross-site Request Forgery) protection, and encryption. Furthermore, this framework is divided into individual modules that adopt modern PHP principles allowing developers to build responsive, modular, and handy web apps.
5. **MVC Architecture Support:**
The MVC pattern of laravel ensures clarity of logic and presentation. This architecture support helps in improving the performance, allowing better documentation, and has multiple built-in functions.
6. **Migration system for databases**
Laravel migration system helps to expand the structure of the database of the web application without re-creating every time developers make a change. Owing to this feature, the risk of losing data is very less. It not only offers the facility to change the database structure but it helps to do this by using PHP code instead of SQL. In addition to this, Laravel Schema Builder helps to create database tables and inserts indices or columns promptly.
7. **Unit-Testing**
Many web app developers like Laravel due to the way it facilitates unit testing. This framework of PHP web development is capable of running many tests to ensure that new changes done by programmers do not unexpectedly break anything in the web application. Generally, laravel is considered to have stable releases in the industry as it is careful of the known failures. In addition to this, it makes it easy to write unit-tests for its own code.
8. **Security**
Application security is one of the most important concerns in web application development. While developing an application, every programmer has to use some effective ways to make it secure. Laravel takes care of the web application security within its own framework. It uses hashed and salted password that means the password would never save as the plain text in a database. It also uses “Bcrypt Hashing Algorithm” in order generate an encrypted representation of a password. Additionally, this PHP web development framework uses prepared SQL statements that make injection attacks unimaginable.
**Wrapping Up:**
All the above-mentioned features make PHP Laravel framework awesome and highly preferred framework. This framework is continuously becoming popular among developers and businesses for its unique, classic architecture, where developers create their own infrastructure that is specifically designed for their application.

Hi Folks,

] | That is the SSH2 key exchange. The following is a quick and dirty run down of SSH.
When the SSH tunnel is established the client and server perform a Diffie Hellman (DH) exchange. This is to establish a shared secret between the client and server in order to generate the session keys needed for the encrypted tunnel.
The way SSH does this by first establishing the algorithms. Each side first sends their SSH version (which I don't see in your capture for some reason), and all of the algorithm combinations each supports. The server chooses the first one that matches in both lists. Then the DH parameters are sent, hashed value H (which hashes 7-12 pieces of data), and the signature of H to ensure it hasn't been tampered with. This is most likely the binary data you see in the picture.
I'm skimming over the details, but essentially after all this is said and done there is a value K that only both sides can generate. Using whichever hashing algorithm agreed upon the session ID, H, and K are all used to generate the session keys.
TimC is correct that looking at the data in Wireshark will tell you a lot more. Each of those pieces will be parsed out with nice easy to read labels. *As long as the default SSH port (22) is used.* I've also found that Wireshark sometimes does not associate some TCP packets with the SSH session, and those packets are not properly parsed. This doesn't mean the data did not reach its destination; it just means that Wireshark could not properly interpret the data. Depends on the version of Wireshark you're using.
Here's a [basic introduction to SSH versions](https://security.stackexchange.com/a/70551/52676), with some extra linkage. | It looks like it could be binary data, or it could even be the encrypted data that is being sent across.
If you were to look at it in Wireshark then it would make it more obvious as it shows you each part of the network frame and you would be able to see where abouts in the packet that data is. |

What I learned is that the 10k potentiometer on pin 3 (Vin) forms a voltage divider. When I carefully dial it, I find a spot where I get clean audio (the 10k pot is then at ~ 500 Ω). This is the same with the ready-made breakout board that I used for comparison.
Now the point of not using the ready made module was that I wanted to add a volume control. Apparently scaling Vin is not how one supposed to do that. If I go up or down from the spot where the audio is good, I get distortions, but never a quieter signal.
I also tried to add a pot between pin 1 and the ceramic capacitor that goes to pin 8. The datasheet has three examples:
* gain 20: by default there is a 1.35 kΩ resistor
* gain 50: use a 1.2 kΩ resistor
* gain 200: use no resistor
I only had a 2k potentiometer and when I dial it from 0 Ω up, the signal gets a bit quieter, but I can't get it down to silence. If I remove the circuit between pin 1 and 8 to operate at gain 20, the output is pretty quiet though.
I searched the Internet quite a bit, and I probably miss something obvious. It would be awesome to get some pointers. | 2019/01/08 | [

] | You probably used a linear (B) taper pot. For audio you want an (A) log taper pot, so your 500 ohms will be about 25% of full electrical rotation, not 5%.

[](https://i.stack.imgur.com/y0Xkt.png) | * Gain of 20 is too quiet
* Gain of 200 is too distorted and can't turn it down to get quiet.
Choose Gain =50 with 1.2k in series with cap
Pots do not have a 60dB dynamic range so they usually gang 2 pots {pre-amp gain & power amp gain} to get 30dB in each.
Solution
--------
Ganged Pot
But as Dave say's that needs to be an audio log pot.

First is [Lunascape5](http://www.lunascape.tv/), this is a multi-engine web browser that includes engines for Trident, Webkit and Gecko. So this is a good starting point for modern browsers.

This replaced my previous copy of MultipleIEs installation because I ran into issues with IE6 not working correctly (can't highlight, can't type in forms).

And in terms of the two formats you suggested: I prefer the former. | Doesn't matter from a REST point of view (REST doesn't define URI structure). The client should not know the URL structure before hand so technically it doesn't matter to the client either.
I personally prefer the first style as I think it makes more sense when you have a resource hierarchy. It also allows a client to move back up a URI by simply chopping off the end resource, similar to how you can go back up a directory on a file system by simply clicking the parent button.
But there is no "right answer" to this from a REST point of view. REST is concerned with the transfer of state of resources, not the resource hierarchy or URI definition. |
240,131 | I hope this is not a too broad question, but what are the best practices to achieve fast switching on a MOSFET driven by a PWM signal?
My current knowledge tells me I can do two things:
1 - To use the lowest possible PWM frequency, because switching losses are higher at higher frequencies.
2 - Drive the gate with the maximum possible current, to overcome gate capacitance as soon as possible. To do this, I avoid adding a resistor between MCU and gate, or add a general purpose transistor between MCU and mosfet, so I can drive the gate with higher current.
Currently, I have a PWM that must run at least at 100kHz using a N-channel IRLZ44 mosfet, so first point is not applicable, and the second point is not enough to give me acceptable switching losses. My mosfets are overheating and I would like to find a better solution than using a bigger heatsink.
Should I look for a better mosfet? Or perhaps, should I try adding a capacitor somehow to kick in when PWM signal rises, boosting current through the gate? Or are there other ways to achieve faster switching?

Q1 and Q2 are a push-pull pair of emitter followers. Their output (at M1's gate) is held at approximately the same voltage as the input (modulo the base-emitter voltage), but the BJT's current gain multiplies the current available from the input.
Consequently, you'll need something connected to the input which can get up to the gate voltage you'll want to use. If you are using a microcontroller its output voltage will probably be 3.3V or 5V.

You can find MOSFETs designed to work at these gate voltages, but most power MOSFETs work best with something more like 12V, so you'll want to add additional circuity to perform the voltage conversion. See [driving low side of a mosfet bridge with 3.3V](https://electronics.stackexchange.com/q/56140/17608) which also includes a more complex discrete MOSFET gate driver. |
240,131 | I hope this is not a too broad question, but what are the best practices to achieve fast switching on a MOSFET driven by a PWM signal?
My current knowledge tells me I can do two things:
1 - To use the lowest possible PWM frequency, because switching losses are higher at higher frequencies.
2 - Drive the gate with the maximum possible current, to overcome gate capacitance as soon as possible. To do this, I avoid adding a resistor between MCU and gate, or add a general purpose transistor between MCU and mosfet, so I can drive the gate with higher current.
Currently, I have a PWM that must run at least at 100kHz using a N-channel IRLZ44 mosfet, so first point is not applicable, and the second point is not enough to give me acceptable switching losses. My mosfets are overheating and I would like to find a better solution than using a bigger heatsink.
Should I look for a better mosfet? Or perhaps, should I try adding a capacitor somehow to kick in when PWM signal rises, boosting current through the gate? Or are there other ways to achieve faster switching?
**Update:**
I thought the question didn't need an example circuit diagram, but here goes it:
[](https://i.stack.imgur.com/sgMPq.png)
I got to this circuit based on other questions I asked in here. I'm using 5V and the load is about 1A. As you can see, I'm driving a transformer. In this configuration, I have 10 Vpp on transformer primary, and secondary elevates this to 1500 Vpp.
Based on current comments and answer, it's already pretty clear to me that using a driver is the easiest, cheapest and simplest way to achieve lower swirching losses. But if there's a way to improve the circuit without a driver, I would be interested on learning about it. | 2016/06/09 | [

] | 1. provide a suitable gate drive circuit that can sink/source a high enough current and at a decent slew rate (others have posted about a dedicated gatedrive)
2. Correctly choose your gate resistor w.r.t. gate charge curve (or total gate capacitance). Too high and you will switch slower and more switching losses. Too low and there is a chance of power cct ringing (increases your losses) and worse-case... setting up a pierce osc
3. If you are switching an inductive load KEEP the the stray inductance between the cathode of the freewheel diode and the FET very, very low (not as low as convenient as low as you can - re-layout if needed)
4. Again, if you are switching inductive load, do not overlook the reverse recovery of the diode. choose an appropriate diode
5. Minimise the gate-source lead inductance (twisted pair, short), again not short for convenience, short as possible.
6. if you are power switching, minimise stray inductance to the bulk DClink capacitor. Again not short for convenience, but as short as possible.
7. consider some form of lamina busbar w.r.t. 5 | Good gate drive is a step in the right direction and has been stated in other answers. Now it is time to look at T1 .There will be some leakage inductance between each leg of the CT primary.When you turn off Q5 or Q6 the current is broken .Energy stored in leakage inductance will go into horrible high voltage spikes in your circuit .You must deal with this to stop Mosfet failure .When you plug in ballpark figures for this inductive energy that on your circuit is wasting and multiply by frequency to estimate power loss you will find that these losses are bad .So try to recover the wasted power to limit the voltage spikes and keep the mosfets cool.One straightfoward way to recover this energy is to build your passive snubber that burns power into a resistor so the fets do not blow anymore.Then optimise the waveforms .Now decide if you want to put the energy into the input or the output or some aux device like say what I did was the cooling fans .Now all you need to do is build a small DC/DC convertor to do this .You should be able to get 90% back without too much effort.You could also try an active clamp system .Active clamps are easy to drive .I have not implemented an active clamp. |

] | There are general tolerances, often defined for different industries.
You cannot expect that a surgical instrument is designed with the same general tolerances as a drilling rig.
If you have found a norm for your industry, e.g. this [ISO-standard](https://www.engineersedge.com/mechanical,045tolerances/general_iso_tolerance_.htm), than there are still different classes of "tightness" you can choose from.
Here should just check what is appropriate for your design such that it still fits/works. In my experience most companies have the general tolerances on their drawing templates by default. | Bound the problem from two different directions.
First, start with your process capability. What tolerance can you actually hold? This will vary greatly depending on whether you are doing casting vs milling vs grinding etc. If you have a bunch of similar parts lying around, measure them and compute the standard deviation. Remember that 68% of parts will be within +/- 1 std dev, 95% within two, etc. E.g. if you have a mill that's producing parts with a standard deviation of say 0.010", then only a few per million would be outside of +/- 0.060". That sets your lower bound. Any less than this, and you'll be scrapping parts that you don't want to scrap. If you don't have any similar parts, then do some research on typical tolerances using your process, whatever it is, and probably round up a little.
Then, thing about what dimension you need the part to have to satisfy fit form and function. You said it doesn't have any engineering requirements, but it does have to have something. If the nominal dimension is 2", I'm sure the part wouldn't work if the shop gave you something that was 200". Figure out the biggest and smallest parts that would actually work. This sets the upper bound of your tolerance. E.g. maybe it's +/- 1".
So now you've got a range. in our example above, if your tolerances are any tighter than +/- 0.06", your shop can't make them and that will make it expensive. If it's looser than +/- 1.00", the parts won't work. Anywhere in between will be perfectly fine, so just pick something that range. Split the difference and call it +/- 0.5" and you're done. |

] | If you are interested in the history of molecular biology this is an interesting question.
Basically transformation came to be used to describe experiments in which the phenotype of an organism was changed by the uptake of DNA, and because of the way this developed in bacterial systems this DNA was usually a plasmid. Then it became possible to use purified phage DNA to infect cells, whereupon the 'transformed' cells produced phage particles - for obvious reasons this was called transfection.
When efforts turned to getting the same techniques working with cultured animal cells many of the vectors were based on viral genomes (e.g. SV40) and these workers referred to this as transfection. At this point the distinction between the two terms became meaningless, and usage tends to be for historical reasons. Interestingly in molecular manipulations of yeast, where there are no viruses, the transfection word is rarely used. | As far as I know (and I haven't found no evidence against it) this is mostly a semantic difference. Both processes describe the addition of genetic material into cells using various techniques.
Transformation is here mostly used for bacterial work (transforming plasmids for example), while transfection is almost exclusively used for eukaryotic cells. The reason may be, that the term transformation is used in eukaryotic cells as well to describe the progresion of cells into cancer cells.
The techniques are not very different and there are a lot of them. Transfections often use transfection agents, which form pores in the cell membrane through which the DNA can enter the cell. This can also be done by using a short electropulse. A lot of transformations are done using "chemically treated" cells, where the cells are brought into a state in which they take up DNA which adheres to their outside.
The Wikipedia articles on [Transfection](http://en.wikipedia.org/wiki/Transfection) and [Transformation](http://en.wikipedia.org/wiki/Transformation_%28genetics%29) gives you more details on the methods. |

27,139,052 | I have VMWare installed on Windows 7. In VMWare, I have an Ubuntu Machine with the environment to develop Android applications. My machine has an i7 processor. For the VM, I assigned two processors with two cores and enabled Vt-x.

You need:
1. An Intel CPU (HAXM is Intel only)
2. Enable VT-x in the BIOS
3. Enable VT-x in the VMWare Host settings for the CPU and MMU virtualization
4. Enable "Expose hardware assisted virtualization to the guest operating system"
5. (Windows Server only) Disable Hyper-V
6. A version of VMWare that supports exposing the HV inside the guest OS.
7. Install HAXM on the guest OS
See:
<https://communities.vmware.com/docs/DOC-8970>
With these steps, I was able to start a HAXM accelerated x86\_64 Android VM inside a Windows 2012 guest OS under ESXi 6.0.
Note: I had to use a software-based GPU to get the VM to start, but I don't have a capable graphics card in the server, so that may be related to VM configuration/limitations and/or the underlying hardware capabilities of my server. | I kept reading about it and discovered that is not possible to enable HAXM on a virtual machine (it would be like virtualize over virtualized).

The question has been closed at least twice for being unclear. The question has undergone some minor edits but the fundamental confusion is still there.
There are currently 11 answers (and several now-deleted answers) that cover a variety of possible solutions. It is unclear why none of them suffice for what the querent has in mind.
If their problem persists across systems, then adding a system tag won't help. Or maybe this is a system-specific problem, which could lead to more detailed answers. Until the querent clarifies their presenting problem, the matter of system tagging is irrelevant here.
The querent needs to explain their preferences, not because their preferences are *wrong*, but because they're unclear and confusing. Some of the question criteria seem to be arbitrary and contradictory (e.g. they want to ban certain options without banning those options). There are several obvious solutions, yet none of them are sufficient.
Maybe there are additional factors that are specific to their game or their player group. Or maybe an obvious solution is sufficient (e.g. ban the options they don't want) but the querent is rejecting them for unspecified personal reasons. Unless the querent clarifies what they want to accomplish and why, then the site users won't be able to provide informed answers. | it's tricky...

] | It should be closed with further details needed, because it's not a system-agnostic question. System matters for understanding the problem and understanding what solution to apply. Factors that the system influences include but are not limited to:
* What actual qualities do the “exotic” or “normal” races have that would have a player gravitate toward or away from them? In fact, what specifically makes them different at all? We need to consider this stuff if we're going to provide guidance on how to point players in a different direction.
* What kinds of stories is the system interested in telling? How does the choice of race affect the story, or create or resolve problems?
* What does the system offer in terms of incentivisation that the group can utilise? What concrete tools are available for shepherding players and how should they be used?
* In fact, what's the player/GM relationship here, and is there even a GM at all? This changes the power dynamics when making requests of others at the table or when implementing changes—some games vest significant authority in the GM, some vest no special authority at all in them.
These are factors that do not have a “neutral” or “agnostic” answer. Each system (or the lack of a system entirely, maybe it's freeform) has specific answers, where “nothing defined on this topic at all” is also a relevant answer for readers to know.
This means that in different systems, the answers vary a lot.
* In D&D, a group with highly varied races isn't a big issue and solves a lot of problems.
* In a Warhammer game, it *creates* problems for humans to adventure with non-humans.
* In a World of Darkness game, the answer is digging into splat mixing vs not, and answers about splat mixing tend to be in the vicinity of “yeah, people try that, but it doesn't actually work too well. If you're going to do that, here's how.”
* In Dresden Files, it takes the story in a different direction. There's specific tools the game uses to address fey creatures (narrative permissions related to free will, different fate point allowances) and unique incentives to pick them. It's a significant consideration whether your characters can pass as human; this doesn't matter in D&D.
In lieu of any specific information about the system, people are assuming D&D, assuming its constraints and situations apply, and they're name-dropping DMing and Pathfinder out of an assumption they're relevant. This is pretty fair—it's quite clear the question seems to be addressing D&D, but doesn't want to say so for some reason.
Specifying the system to us is helpful. It gives people knowledge of the tools they can work with, and that's important. Withholding such information and just pretending it's system-agnostic isn't doing anyone any favors. It leaves answerers armed with less knowledge for addressing the problem, and leaves them providing weaker solutions and guidance than they could otherwise speak about. Personally, it seems like a long line of sytem-agnostic-but-actually-D&D questions that assume that the tabletop RPG space is equivalent to D&D and therefore D&D questions can be system agnostic because it's all the same. (We saw this happen a lot during our early years on this site.)
The OP ought to tell us specifically what system or systems they're trying to solve this issue in, rather than beating around the bush. RPG.SE is about [solving practical questions based on actual problems that you face](https://rpg.stackexchange.com/help/dont-ask), not about generic problems that generically exist out there somewhere. The OP is having this practical problem in a specific system or set of systems, and should tell us what those are. | it's tricky...

* In Dresden Files, it takes the story in a different direction. There's specific tools the game uses to address fey creatures (narrative permissions related to free will, different fate point allowances) and unique incentives to pick them. It's a significant consideration whether your characters can pass as human; this doesn't matter in D&D.
In lieu of any specific information about the system, people are assuming D&D, assuming its constraints and situations apply, and they're name-dropping DMing and Pathfinder out of an assumption they're relevant. This is pretty fair—it's quite clear the question seems to be addressing D&D, but doesn't want to say so for some reason.
Specifying the system to us is helpful. It gives people knowledge of the tools they can work with, and that's important. Withholding such information and just pretending it's system-agnostic isn't doing anyone any favors. It leaves answerers armed with less knowledge for addressing the problem, and leaves them providing weaker solutions and guidance than they could otherwise speak about. Personally, it seems like a long line of sytem-agnostic-but-actually-D&D questions that assume that the tabletop RPG space is equivalent to D&D and therefore D&D questions can be system agnostic because it's all the same. (We saw this happen a lot during our early years on this site.)
The OP ought to tell us specifically what system or systems they're trying to solve this issue in, rather than beating around the bush. RPG.SE is about [solving practical questions based on actual problems that you face](https://rpg.stackexchange.com/help/dont-ask), not about generic problems that generically exist out there somewhere. The OP is having this practical problem in a specific system or set of systems, and should tell us what those are. | ### [system-agnostic](https://rpg.stackexchange.com/questions/tagged/system-agnostic "show questions tagged 'system-agnostic'") is an appropriate tag here. We do not need to know the system.
That certain systems have mechanics baked in for handling OP's problem is entirely irrelevant. If OP was playing one of those, they likely wouldn't be having this problem. And even if they are, *the problem is still widely applicable to systems that don't have such mechanics*, and system agnostic solutions will still be helpful.
### OP doesn't have to justify their preferences to us before we can answer their question.
There were some comments bordering on badwrongfun being thrown about, [and we shouldn't do that here](https://rpg.meta.stackexchange.com/questions/5174/can-we-affirm-that-rpg-se-embraces-a-plurality-of-playstyles). It is perfectly fine for someone to prefer a particular play experience at the table, and OP is looking for methods to help them navigate pre-game social interactions in order to achieve their preferred play experience. It does not matter why they want this particular outcome, they want it, and that is okay, and we should be well equipped to handle this question without having OP defend or even explain their preferences.
This type of social interaction question is standard fare for this site. Leave it open. |

Maybe there are additional factors that are specific to their game or their player group.

System matters for understanding the problem and understanding what solution to apply. Factors that the system influences include but are not limited to:
* What actual qualities do the “exotic” or “normal” races have that would have a player gravitate toward or away from them? In fact, what specifically makes them different at all? We need to consider this stuff if we're going to provide guidance on how to point players in a different direction.
* What kinds of stories is the system interested in telling? How does the choice of race affect the story, or create or resolve problems?
* What does the system offer in terms of incentivisation that the group can utilise? What concrete tools are available for shepherding players and how should they be used?
* In fact, what's the player/GM relationship here, and is there even a GM at all? This changes the power dynamics when making requests of others at the table or when implementing changes—some games vest significant authority in the GM, some vest no special authority at all in them.
These are factors that do not have a “neutral” or “agnostic” answer. Each system (or the lack of a system entirely, maybe it's freeform) has specific answers, where “nothing defined on this topic at all” is also a relevant answer for readers to know.

177,680 | In Paris you have the RER lines, which are denoted by letters, and the Paris Metro, which are denoted by numbers.
My question is... are there any Paris Metro stations that are outside of zones 1-3?
Marne-la-Vallée Chessy (the station you'd use for Disneyland Paris) is in zone 5 but the Paris Metro does not go there - just the RER. RER A, to be exact.
Versailles-Chantiers (the station you'd use for Versailles) is in zone 4 but, again, the Paris Metro does not go there - just RER C.
Mairie d'Issy, the southern terminus of line 12, is in zone 2.
Based on my spot checking, it does indeed seem to be the case that all Paris Metro stations are in zones 1-3 but my spot checking isn't comprehensive.
As for why this is relevant... if every destination you're going to be visiting in Paris can be accessed through numbered routes then that means that a Paris Tour travel pass for zones 1-3 would be sufficient vs the more expensive zones 1-5 pass. | 2022/11/23 | [

I think you'd be better making this decision based on looking where your intended destinations are rather than abstracting to whether or not the Metro in general goes outside of zone 3. What if one of your destinations isn't on a Metro line? Last time I visited Paris there were multiple places I visited which were best reached by tram or bus. They were all within zones 1-3, but knowing there are no zone 4 metro stations wouldn't have told you that! | To add to the previous answer :
The Metro line 14 is [set to](https://www.ratp.fr/en/groupe-ratp/metrotrains/m14-extension-orly-airport) open its connection down to Orly Airport in 2024, which would be firmly in Zone 4 |

11,962,925 | I just started to use memcached. We use spymemcached java client via a Pajamas Proxy server (all with default setting and 1024 mb memory allocated). Setting the program to access memcached is very simple and straightforward, but I have one observation though:
when the cached value size drops to a certain point (in my case: about 1450 bytes), the performance drops dramatically (from 4 msecs to 200 msecs each retrieval).
Does this mean that the value that I want to cache has to be above certain sizes? How would I be able to determine such sizes?

No, there is not.
In the node.js architecture, when an event is pulled from the event queue, it's tied to a callback. The interpreter calls that callback and that callback runs to completion. Only when it returns and the stack is again empty does it check to see if there is another event in the event queue to run.
So, it has absolutely nothing to do with a number of instructions. node.js runs your Javascript as single-threaded so there is no time slicing between pieces of Javascript which it sounds like your question perhaps was anticipating. Once a callback is called that corresponds to an even in the event queue, that callback runs until it finishes and returns control back to the interpreter.
So, it goes like this:
1. Pull event from the event queue
2. Call the Javascript callback associated with that event
3. Javascript callback runs until completion and then returns from the callback
4. node.js internals check event queue for next event. If an event is there, go to step 1 and repeat
5. If no event is there, go to sleep until an event is placed into the event queue.
In reality, this is a bit of a simplification because there are several different types of event queues with a priority order for which one gets to go first, but this describes the general process as it relates to your question. | There is no set number of instructions that get processed before checking the event queue. Each message is run to completion. From the Mozilla documentation (<https://developer.mozilla.org/en-US/docs/Web/JavaScript/EventLoop>):
>
> Each message is processed completely before any other message is processed. This offers some nice properties when reasoning about your program, including the fact that whenever a function runs, it cannot be pre-empted and will run entirely before any other code runs (and can modify data the function manipulates). This differs from C, for instance, where if a function runs in a thread, it may be stopped at any point by the runtime system to run some other code in another thread.

>
> A downside of this model is that if a message takes too long to complete, the web application is unable to process user interactions like click or scroll. The browser mitigates this with the "a script is taking too long to run" dialog. A good practice to follow is to make message processing short and if possible cut down one message into several messages.

I would not expect HIPS material sold for 3D printing use to have much if any strength, especially for moving parts.

1. Regarding the "Jawbone" used by Samson :
In Judges 15:14-19, Samson (Shimshon, שִׁמְשׁ֔וֹן) defeats the Philistines with an odd weapon - a donkey’s jawbone (Lehi, לְחִ֣י) - calling the place of his victory “Level-Jawbone” (רָ֥מַת לֶֽחִי).
While Samson was thirsty after the Philistine battle at Lehi, he prayed to find something to drink and God cleaved the socket of Samson’s weapon to make water pour out of the donkey’s jawbone. After reviving his spirit by drinking water from the donkey’s jawbone, Samson called his place of rejuvenation “Eye of the Crier” ( עֵ֚ין הַקּוֹרֵא֙). - The event of Judges 15:19 appears to provide an origin story for the natural Spring at Lehi.
[Shoftim (Judges) 15:19] “ And God cleaved the socket which was in the jawbone, and water came out of it, and he drank, and his spirit returned and he revived; therefore he called its name En-hakkore, which is in Lehi until this day. “ ( וַיִּבְקַ֨ע אֱלֹהִ֜ים אֶת־הַמַּכְתֵּ֣שׁ אֲשֶׁר־בַּלֶּ֗חִי וַיֵּצְא֨וּ מִמֶּ֚נּוּ מַ֙יִם֙ וַיֵּ֔שְׁתְּ וַתָּ֥שָׁב רוּח֖וֹ וַיֶּ֑חִי עַל־כֵּ֣ן | קָרָ֣א שְׁמָ֗הּ עֵ֚ין הַקּוֹרֵא֙ אֲשֶׁ֣ר בַּלֶּ֔חִי עַ֖ד הַיּ֥וֹם הַזֶּֽה ) | It was explained to me, that for instance the Oxgoad was used because the Jews were very poor at the time and didn’t afford swords and such of the time. I think also to illustrate their use of what was given to them. The jars and torches was a fear and stealth tactic to sneak in then illuminate the enemy camp, that is why he reduced his army to 300, god didn’t pick them, Gideon selected the men that didn’t let their guard down and stayed alert when they stopped to drink, |

] | Historical interpretation
-------------------------
In the time of judges the people were disorganized, there was no king, and no army, no tax base to support dedicated weapons production or a standing army and thus and no military weapons, so the people used farm implements ("ox goads") or household implements ("pots") when they fought.
They fought with the tools of ordinary life.
E.g. We see in the song of Deborah a complaint that the people have no weapons:
*a small shield or a spear was not seen among forty thousand in Israel.* (Judges 5.8)
In fact this type of disorganization is one of the themes of Judges, and is one of the reasons the people clamor for a king when they are threatened by an organized army. After Isreal has a king, you see more normal weapons being used.
Homiletical theme
-----------------
The use of all these various weapons create many teaching opportunities as given in חִידָה's answer. But the larger unifying theme is that God wanted the people to rely on him rather than on the strength of their own army or their own devices. He created many miracles for them to defeat their enemies with the simple farm tools they had. In this way, the call for a dedicated tax base to fund weapons and training and a dedicated king to lead a standing army is viewed as a rejection of God's provision (1 Sam 8.7)
*'And the Lord said to Samuel, “Obey the voice of the people in all that they say to you, for they have not rejected you, but they have rejected me from being king over them."*
Many view the call for a king as just an attempt to want to imitate other nations as if this was about fitting in, but if you take into account that they had no weapons or trained soldiers but were being attacked by armies that did, then the desire for a king is understood more fully. | It was explained to me, that for instance the Oxgoad was used because the Jews were very poor at the time and didn’t afford swords and such of the time.

This demonstrates God's great power, as the city fell without use of regular weapons. God didn't need swords or a big army, he just needed Gideon to trust him.
Samson uses a donkey's jawbone to strike down a thousand men (15:15)
The way this one was explained to me was that touching a dead animal body was considered very unclean, and Samson was meant to be holy and set apart. This shows how far God's people have fallen.
Perhaps the use of strange weapons also has something to do with showing the sin and evil amongst God's people, as they don't even use 'honourable' methods such as swords? |

Where and when did the events take place over the 350 year stretch of Judges? Was the fighting from a short, mid, or long distance? Would the defender know he’d soon be attacked? Did the situation force them to be creative or had they brought the weapons they wanted?
After reading the 5 stories I don’t see these as thematic. In Jael’s, Gideon’s, and Woman with a Millstone stories, the weapons appear to be exactly what they needed given the circumstances. The other two stories are that of Shamgar, the first “minor judge”. That seems a little vague. The last of the 5 is Samson’s; he could use any or no weapon.
-Shamgar uses an Oxgoad (Judges 3:31)
Shamgar slew 600 with an oxgoad, an 8’ long farm tool used for spurring oxen. He was the first of the “minor judges”, so this is an introduction.
-Jael uses a Mallet and Tent Peg (4:21)
Jael kills the deep-in-sleep Sisera in her tent with a mallet and tent peg. Others were in pursuit of Sisera and she just helped them. She had to kill Sisera quickly and powerfully at night.
-Gideon’s army uses Jars, Torches, and Trumpets (7:20)
Gideon’s 300 soldiers had to attack the uncountable Midianites. Gideon had to design a surprise attack, so they loudly blew their trumpets and broke their jars. Taking their torches in their left hands and trumpets in their rights, they cried, “A sword for the Lord and for Gideon!” From the mountain top down they boldly shouted and attacked, and the Midianites saw the torches and enemies all around them. They ran in sudden terror.
-Woman uses a Millstone (9:53)
Abimelech was fighting to get into the city’s tower, but the woman cast a millstone down onto his head. She really couldn’t have used many other weapons, especially from the tower.
-Samson uses a Donkey’s Jawbone (15:15)
I think this stresses the point that a donkey’s jawbone wasn’t much, but Samson was the one with immense strength. He needed very little and even killed 1,000 with this. |
