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.

The advice I have always seen is to delay as long as possible, while informing the other companies of your situation.

Yeah, don't fall between two stools.

I understand security is difficult. I understand why you need professionals. If this were an enterprise app I would obviously hire professionals, but this is just for learning.

Taking a course is a good recommendation, but I think the time invested to reward of that would be minimal for me.

Well, I guess the point that people want to make here is that security is too hard for this forum. Though I would argue that in your case I don't see any cause for alarm. You are not releasing it and are well aware of the risks involved. But you won't have much feedback here. Like most things, it is not black and white. You want to have just the right level of security without too much inconvenience and cost. Otherwise we would have biometric scanners on every door of our homes. I think a more reasonable recommendation is (if you care about the app's security)
1. learn the pro/con of the different security schemes
2. know how to pick which one is suitable for your requirements
3. never try to invent your own scheme
4. never try to re-implement a known scheme either

yes you did, you even ignored the part where we said "don't use SHA-256, it's bad" and used SHA-256

Fair enough. I meant "originally" as in when I actually posted my code/github a few pages ago, though you are right that your link has my first security questions. I recognize "originally" was a misleading word.

Please go and take mooc on it or something, it's not exactly something you can pick up on a forum.

Man, we have a really annoying client. They want us to optimize our app deployment process because it's taking too long in their opinion (52 seconds on their machines).

Hm. 52 seconds seems long to wait for app deployment. I'd probably complain too. If all their employees open and close the apps a lot, that's a lot of wasted time.

Whether you should pay attention to it depends on whether it can reasonably be sped up, whether your competitors have better speed properties and how much the client is paying you.

If I misunderstood and it has nothing to do with client side load time, but is the time it takes for your devs to deploy updated versions, then lol.

It's the time it takes to deploy it to the servers and has nothing to do with client-side load times.

Also, it's pretty hard for us to optimize it any further. On our servers it takes 15 seconds to deploy...

Then I don't get it. Why does your client have to deploy often enough that they care about how long it takes?!

In fact, why does your client have to deploy at all? Are they too cheap for a service contract?

They have their own, huge IT department. Supposedly deployment taking this long breaks their Kubernetes in some way.

So i have problem with Selenium, running Firefox and Python 3.6.2. I am navigating trough webpage and need to open and select item from menu which is normaly opened by right click. And i have problem scrolling trough that menu.

Both:


install_download = wait.until(EC.element_to_be_clickable((By.XPATH, paths['install_download'])))
        install_download.click()
        actions = ActionChains(driver)
        actions.context_click(install_download)
        actions.send_keys(Keys.ARROW_DOWN)
        actions.send_keys(Keys.RETURN)
        actions.perform()

and


install_download = wait.until(EC.element_to_be_clickable((By.XPATH, paths['install_download'])))
        install_download.click()
        actions = ActionChains(driver)
        actions.context_click(install_download).send_keys(Keys.ARROW_DOWN).send_keys(Keys.RETURN).perform()

Fail. Menu is opened but no move down (or enter) is performed.

While with usage of pyautogui it is succesfull.


        install_download = wait.until(EC.element_to_be_clickable((By.XPATH, paths['install_download'])))
        install_download.click()
        actions = ActionChains(driver)
        actions.context_click(install_download)
        time.sleep(2)
        pyautogui.press('down')
        pyautogui.press('enter')

However i cant use pyautogui since it makes a lot of problems when running with screen locked (unless You have fix to that). Pressing down manually on keyboard also works.

Have you tried using submit() instead of perform()? You could also try with ENTER instead of RETURN (and I don't know if you need perform after return, another thing to test would be to try arrow_down and then submit).

I did try "ENTER" and also u'\ue007' both dont help here. But havent tried submit(). Will look at it tomorrow.

Also i looked closely at documentation of ActionChains and i suspect this might be some tricky thing releted to focus, will test it.

Javascript.

Can someone explain why this works:

txt.split("\n").map(x => parseInt(x))

But this only works for some lines:

txt.split("\n").map(parseInt)

In fact in this latter case, only the first number is correct, the rest is either NaN or some completely different number, yet still within a factor of 10 or so of the correct number.

I wouldn't even know where to look up the difference between those... I'm not even sure I want to know about this...

It seems parseInt takes two parameters (string, radix). Array.map will pass your function three parameters (value, index, array). The first one, the value of the element, will be used as the string input to parseInt. The second one, the index in the array, will be used as the radix. Therefore all your calls to parseInt will use a different radix and life is hard.

Does anybody know how to identify which unit types are associated to unit ids in any action, such as select or attack move from rep data? I'd like to use screp (https://github.com/icza/screp) for some analysis.

How many interviews does it take you to get a job offer and how many years of experience do you have?

Not sure if this was directed to anyone specific but I can answer for myself:

My first job I got dirt lucky on. While I was working part time during my studies, a guy overheard me trying to explain what a dual band router was to a customer, asked me what I was, and handed me a job interview when he found out I was studying CS. Had the job soon after. (I also applied and got an interview for another place, which I ended up not getting)

After quitting that job a year and some months later I applied for like 20 jobs, went to 5-6 job interviews, and got nothing. After a while a buddy from school landed me a job interview for his workplace, which accepted me soon after. So everyone claiming "connections is key" was, at least in my case, 100% true. Knowing someone somewhere makes everything so much easier.

That said, now that I have 3 years of experience, I don't think I would have any trouble landing another job if I was to lose this one. It's most difficult coming fresh out of school

When I was in University, for my internship, I shot out probably 15? resumes to various positions. I got 2 interviews, 1 job offer. I took the job, was pretty happy about where I was working and made a good impression.

After I graduated, I took ~6 months off to relax, then I put in one application back to the same company where I did my internship, and got the job offer about about 3 hours later.

If you have connections, life is easy. Referrals are also helpful, especially if the person the referral comes from is in the same department/role as the applicant.

^ this.

You could do stuff like


const intParser = string => parseInt(string, 10)

const parsedInts = yourArray.map(intParser)

or (if you want to use different radixes at times):


const makeIntParser = radix => string => parseInt(string, radix)

const intParser10 = makeIntParser(10)

const parsedInts = yourArray.map(intParser10)

It can be worth it if you need to reuse this again, otherwise

const parsedInts = yourArray.map(x => parseInt(x,10))

is still concise enough.
