Thread Rules 1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution. 2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20) 3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible. 4. Use [code] tags to format code blocks. |

While it does have its issues, it has come a long way. Never ever use it for math that's for damn sure. Don't forget about Date, which isn't even consistent across browsers.
That's the main problem with JavaScript: Everyone is always looking at the browser implementations - which indeed are pretty terrible due to their inconsistency. The language itself is actually quite nice and each iteration is getting nice new features. I actually prefer it to other scripting languages like PHP.

do you guys know a way to make a mysql database smaller?
with smaller I don't mean to compress it, actually delete some portion of data without violating foreign keys. I have a db with say 100k hotels in it and I need just 4-5 to test my app. It can be 5 hotels in 3 countries with each country having 2 cities etc. instead of the full hotel-country-city tables. Size matters because im gonna put it in a small free cloud db.

Create a new one from scratch that has a tiny subset of all the things you see from whatever example queries you're going to run. It should not be hard to enumerate (even manually) if you're actually talking 4-5 entries per table.
Or, throw money at it if the time is too expensive.

Exactly. Create a fresh DB and then perhaps implement a faker to fill it up with some basic, random data to fill it up with and off you go.

Any suggestions for introducing a group of developers with varying degrees of experience to unit testing?
A little background: I recently joined a new company (a little more than a month ago), and the application they develop is written in C# .NET using MVC design pattern. There are 100s of classes and some contain over 10,000 lines of code. There also are 0 unit tests, so in this sense I am working on legacy code.
We have weekly developer sit-down meetings once a week to discuss what we're working on, etc, and I've been able to get a few people on board with pushing for introducing unit testing. I've shown the most interest and so have taken the initiative with heading this venture. We've decided on simple MSTest for the runner, Moq for mocking the external sources, and Fluent Assertions just for readability and easier assertion writing.
A few general notes: 1) Some people have never written a unit test ever before. 2) We currently use Subversion for version control, though the push to move to Git or something where we can do some form of "gated checkins" is another endeavor. 3) Though I am interested and understand the value of unit testing, I am not an expert on it. None of us are very proficient at it for that matter. 4) Others understand the importance of unit testing, but the main issue is them not knowing how to test and then the usual pushbacks of "not enough time to write them" 5) We are using VS 2012 at the moment, hoping to upgrade it to VS 2015 eventually. I notice VS 2015 has some convenience features for unit testing for instance that we don't get in 2012 editions.
My main questions...: 1) What are some tools, tips, or extensions we can use to decrease the amount of time spent with the initial setup of a unit test? 2) More generally, what is a good way to help convince others that not only are unit tests important (we all agree on that), but that they should put in the effort to do it themselves? 3) Have you been in a similar situation before and how did you handle it?
|
Ad.3. At the previous company I worked for we were in this situation. How we handled it was learning unit tests by doing them for some of the core functionality of the product (we did unit, acceptance and integration tests). Obviously this didn't cover much but we learned the ropes and didn't stress over it too much. We basically treated this endeavour as pure practice. Where we actually implemented it was in projects which came after that (we tried to do real TDD from then on). We would also use it if new functionality should be added to the old projects but it's rarely the case with stable stuff that's been running for years without much change.

I want to create table tennis exercise plans like this one
![[image loading]](https://i.imgur.com/EBFJT3D.jpg) Is it possible to code an HTML5 online editor that creates these with a WYSIWYG front? So you can drag arrows, highlight areas etc.. all in the browser and then export. Where do I even start if I want to create this?

yes
look into canvases, though you'll need javascript for mouse interaction, I think

Here's a start, but definitely possible:

I used express and mongodb to make a single page app. When the page loads, a bunch of information comes from the database through the view (EJS) into static javascript, where it is used. Google maps does some stuff with the information. Every 10 seconds, I am POSTing new information back to the server side to be stored in the database.
Is this bad? From the users end, it looks like the page is constantly loading. Do I need to start using websockets (socket.io)?

This is more like the downside to using Node... I've noticed with heavy data apps, it tends to slow down on the user side heavily. Socket.io is a real time data solution, so that can help in the front side.

Why are you saving data to the DB every 10 seconds? And what kind of data? Is it huge amounts of data? How relevant is this? How far back do you have to go in the data history? How often is data received from the DB?
Those are all pretty relevant questions pertaining to your problem.

Solution: Use background threads, in other words, workers.

This looks like a good solution. The only problem is that my digital ocean $5/month server only has one worker.

Right now I'm just posting lat lng coords to the server, so that when the user quits, the database will contain their location. Every 10 seconds the client posts, and the server writes the information to the database. Data is received from the database only when the user loads the page.
The next iteration will also be reading data from the database and sending it to the client every 10 seconds, which will allow the user to see other user's on the map with him.

sounds like you have in mind a project that needs more worker threads
|
I want anybody's advice.
So, shit is funny if it was not disastrous. I downloaded a stupid movie for my wife (stupidass four fantastic which I'm sure is complete shit) and dragged a "ransomware" called cerber. So it encrypted all my files - ten years of work, but I have most of it printed somewhere, and parts saved in USB keys and in my other portable PC. What I lost for sure tho are some photos which are dear to me, and a few papers that I didn't saved and haven't finished (specifically freaking notes about a book I was reading and that took me ages to write...).
Basically, according to everything I've read, I can't get that data unless I pay the ransom, which is 500 USD (that I don't have). Anybody have some knowledge on the subject and give me his point of view ? It's dead ? Should I keep the datas somewhere ? Or should I format everything, drink some whisky, and accept my idiocy ?

Nah, they usually delete the key after a couple days and it's gone forever
