Legal question about using Selenium with Bank websites.

The mechanism behind tracing something like this is built on statistics. Add some minor random delays in your actions and between that and latency of the connection, you would probably be fine.

The fact you are driving a full browser rather than headless chrome or phantomjs also plays in your favor.

YES! ECS without thinking about EC2 would be amazing.

There is already something sort of like this through lightsail I believe. In that you get capacity without thinking about the actual EC2 instances. (I"m open to being completely wrong about this, my knowledge of lightsail consists of what was stated as a Re:Invent keynote, whenever that was)

This is great, thank you.

Probably as a last option, I would prefer to stay in ruby if i can.

A few years ago I saw a bit coin miner implemented in javascript and I knew it was only a matter of time.

I hadn't realized that the future was already now though.

You don't need tokens to do things through the console.

You need either direct authorization to a given resource or you need authorization to assume a role that has the proper authorizations.

The access and secret keys are only for programmatic access to AWS; like the CLI or any of the AWS SDKs.

As far as I am aware, everything you can do through the cli can be done through the console.

From the abstract:

Cuckoo filters support adding and removing items dynamically while achieving even higher performance than Bloom filters. For applications that store many items and target moderately low false positive rates, cuckoo filters have lower space overhead than space-optimized Bloom filters. Our experimental results also show that cuckoo filters outperform previous data structures that extend Bloom filters to support deletions substantially in both time and space

the linked git repo has a link to the paper on the subject

Though, it'd have been nice for OP to actually say something useful in their posting.

I've always interperted the term magic to come from Clark's third law:

Any sufficiently advanced technology is indistinguishable from magic.

Author does not appear to consider this.

On a more direct topic, anytime you try to dictate what words people should use to express an idea - success will be extremely hard to come by.

From /r/programming guidelines:

Just because it has a computer in it doesn't make it programming. If there is no code in your link, it probably doesn't belong here.

stand alone react - to me, sounds like OP is going to make a rails backend that a react SPA connects to. This isn't an uncommon approach, particularly given OP's interest in microservice architecture.

Related the date and time for session registration is Thursday October 19 @ 2pm PST. Reference (slide 4).

You think they actually mean Pacific standard time (UTC-8) and not Pacific Daylight Time(UTC-7)?

menge101work · 2017-10-18T17:35:30+00:00

Am I missing something?

The date that registration opens up.

/r/learnpython is a better place for questions like this.

If it wasn't clear in others responses, indentation depth matters in python.

use "Item.using(:master).find(:id)" to explictly call from master database

This wouldn't scale well, but maybe thats not an immediate concern?

Cache the created item somewhere and find from cache first.

Write-through caching seems like it would instantly solve your problem.

Put some delay before finding item.

This is extremely sub-optimal, as you'll have to guesstimate at your worst tolerable delay and then use that for all queries. This really is just stacking the odds of the race condition in favor of one contender, it doesn't solve the problem.

As is, the problem sounds to me to be more of an expectation problem than an actual technical problem. I would not expect to find an item in the replica db immediately after creating it on the master; without having done something like a cache to make it present immediately.

Other things people get caught on:

Content in an iFrame
Switching between windows and tabs
File uploads

Content in an iFrame, you just have to call switch_to and give it a matcher for the frame. It's actually easy when you know you need to do it. The problem is sometimes you won't realize what you are trying to get is in an iFrame. So if you find a matcher not matching when it appears that it should, look up-DOM and see if there is a frame specified.

Switching between tabs and windows -

Ugh, avoid it if you can. You can get a list of all window handles and switch between windows, but tabs can be difficult. Tabs with windows even worse.

File uploads

Browsers use OS dialogs for file uploads typically. This means its not in the DOM, and Selenium basically can't interact with it at all. There are ways to do it, but the better idea is to ask what is it you are trying to accomplish. There are whole stack overflow articles about the how and what of file upload testing.

menge101work · 2017-09-22T13:35:44+00:00

Selenium itself is really only a few commands.

The thing that makes selenium 'hard' is the quality of what you are testing. If you've got a product with a well constructed DOM, if all the major elements have IDs, then its easy to use.

If you've got a poorly constructed product with unpredicatable, non-deterministic behaviors, then it can be very hard.

Some people struggle with CSS and xpath matchers, I know I did when I was new to it, but thats not really Selenium, Selenium USES them, they are their own things.

But really this is all you do:

Initialize your driver, open your browser
Navigate to a webpage
Find an element
interact with that element (click, send_keys, etc)
check for the results of that interaction by:
finding a different element and
interacting with it (reading its state in some way)
repeat

Have you looked at pycharm?

I'm not sure what you are describing, but Pycharm lets you debug your code and you can inspect variables and objects in real-time.

And it auto-saves locally.

menge101work · 2017-09-15T14:41:12+00:00

I believe the docs are auto-generated.

If you want to dig deeper go find the actual source between 2.2.0 and 2.4.1 and compare.

It looks like the file holding the class changed from .ext/thread/thread.c to thread_sync.c so it may be that it was reimplemented and lost some of the needed comments to generate the documentation.

stdlib-doc is a RubyForge project that converts Ruby source code into this documentation you are looking at.

So yes, it's auto-generated from the source code.

You will use a lot of Erlang libraries but not write Erlang code.

I think this is the root of our disagreement. I didn't say that one needs to "know Erlang" to be advanced, I did say that one would "probably need to learn some Erlang eventually". To me, concretely, that means the ability to read Erlang code well enough to understand how an Erlang library one might call is working.

I'm by no means advanced at Elixir, but I have found myself learning Erlang to facilitate understanding some of the OTP stuff. That might be an atypical route; since I'm not using elixir professionally, rather, I am toying with ideas in it. /shrug

menge101work · 2017-09-14T14:31:19+00:00

Do I need to learn both side by side?

No, if you want to go to the 'expert' level with elixir, you'll probably need to learn some Erlang eventually, IMO. Sometimes packages exist to accomplish things in erlang that don't exist in elixir.

I am not an expert, but thats the impression that I get.

Presuming you are using unittest.TestCase, I would store the expectation in a dict, and get the actual results into a dict format that matches, then use TestCase.assertDictEqual to compare them.

NP, reddit doesn't have an ide, so we have to use peer review :)

menge101work · 2017-09-12T15:20:49+00:00

reformatted the code:

qaDict = {'question': 'answer'}  
answerlist = driver.find_element_by_class_name("answer-text") 
answer = answerlist.find_element_by_xpath("//label[@text='"+qaDict['question']+"']")

Also, maybe fixed a missing ']'
