I am trying to match a particular pattern in a lengthy string:

NEW ZEALAND AND (data.operator1:"SHELL AND AMP" AND data.field:"NEW ZEALAND") OR (data.operator:purpose AND data.field:crank) OR (data.operator:REGULATOR AND data.field:HELICOPTOR)

1. I want to select all the below values followed by : but not the AND/OR/NOT operator.
2. I am trying to use look ahead and look after/behind feature in Regex but unable to achieve it

Basically a combination of /(?[a-zA-Z ]"

I want to change the strings to title case so that I can clearly distinguish AND/OR/NOT.

New Zealand AND (data.operator1:"Shell And Amp" AND data.field:"New Zealand") OR (data.operator:purpose AND data.field:crank) OR (data.operator:Regulator AND data.field:Helicoptor)

I wrote a small demo in Rust/SDL, which do fade-in and fade-out of the image, plus some occasional random specs. It was super smooth and good, cranking up to 250 fps.

I decided to add change to canvas.set_viewport on each frame with random dimensions. Basically, the same streaming texture (which filled with new tone or noise on each frame) is drawn at random location with random size.

I found there is an (unexplainable) flickering for already rendered rectangles.

I've tried to screencapture it, but on video there is no flickering. I used a normal camera (60fps) and there was no flickering. I've used high-speed mode in my phone and I got flickering recorded, but it looked very different from what I see.

What is it?

The code: https://github.com/amarao/sdl_random/tree/c4757190712f0a996c2aba88b105462942d4ca27/src

The second question: if this is some kind of 'underfined behaviour' from my GPU (nvidia), why is it so? Is changing viewport on-fly supported?

Edit: I changed call to set_viewport into a rect parameter for canvas.copy:

Recently I create my first serverless service. Nothing fancy, just a script that uses FFMPEG to encode some CCTV footage and reduce quality.

After a couple of days, I realize that many of my footage where not there. After stare for some time at the aws lambda metrics panel, I assume that the cause of the problem was too little time and to little memory, so I cranked up the timeout (8 minutes) and max memory (380MB). And then I left it work for a couple of days to see if it would get better. Fast forward to today, I log in on aws and notice that I was never using more than 95MB of memory (as seen on the image).

Last logs

Is this right? Also, looking at the graph, I notice that I still get some errors. Increase the timeout is the solution?

Sorry for the poor quality of the question, I really tried to lookup.

I'm trying to program a vocabulary game. Let me say at the outset that I'm a completely rookie programmer!

I am using a regular expression to hide a word, which I have to guess.

Take for example the chosen_word:

'TO CRANK (STH) UP'

With RegExs I manage to hide the keywords and I have hidden_word as follows:

TO _ _ _ _ _ (STH) _ _

With the RegEx findall() and the filter() methods I get a list of hidden_letters:

['C', 'R', 'A', 'N', 'K', 'U', 'P']

The idea is that we now choose one letter from this list randomly to reveal to the user:

chosen_letter = random.choice(hidden_letters)

n = hidden_letters.index(chosen_letter) + 1

Now the chosen letter's n maps beautifully onto its corresponding underscores in the hidden_word. For example, if the game has randomly chosen the letter 'R', then n will be '2', and in the hidden_word this letter's position is at the 2nd underscore.

I am stuck at this stage now. I want to replace the nth underscore of hidden_word with the chosen_letter. I'm thinking of using either the .replace() method, or the RegEx re.sub() method, but I don't know how to start off.

Could someone please give me hints?

Many thanks in advance!!

I am using a regular expression to hide my word, which I have to guess. I'm not comfortable with the syntax used with regular expressions - outwith the simple examples, I get very confused.

Take for example the verb

My application is unable to handle time operations like time(2) when it runs in alpine docker container on an arm device.

What I have: I am building a native c application which is statically linked to musl with toolchain from musl.cc (arm-linux-musleabihf-gcc). I am using latest alpine container (without image tag).

How it behaves:

• Running binary directly on arm device works as expected
• Running in alpine container on x64 device works as expected
• Running in alpine container on arm device does not work

What's going wrong:

• time(NULL); returns ((time_t) -1) and error=1: "Operation not permitted"
• The timestamps in the log outputs have cranked timestamps
• SSH handshake fails because the validity of the remote certificate is in the future.

However, if I execute date in container's ash the output is valid. Thus, there seems to be a problem that only occurs in alpine containers on the ARM architecture. Funnily enough, I'm switching from Ubuntu to Alpine as we had similar problems there.

Does anyone have any idea what I am doing wrong?

Update #1: Same problem on ubuntu. So the problem seems to be on any docker basis image but only on arm devices.

Update #2: Here is a minimal example TimeTest.c

I have machine A that just cranks out .png files. It gets synced to machine B and I view it on machine B.

Sometimes machine A crashes for whatever reason and stops doing the scheduled jobs, which means then files on machine B will be old.

I want machine B to run a script to see if the file is older than 1 day, and if it is, then reset the power switch on machine A, so that it can be cold booted. The switch is connected to Google Home but understand I have to use the Assistant API.

I have installed the google-assistant-sdk[samples] package. Can someone show me some code on how to query and return all devices then flip the switch on and off on that device?

I am running a query using Hive on Spark which is exhibiting some strange behavior. I've run it multiple times and observed the same behavior. The query:

• reads from a large Hive external table
• Spark creates about ~990,000 tasks
• runs in a YARN queue with > 2900 CPUs available
• uses 700 executors with 4 CPUs per executor

All is well at the start of the job. After ~1.5 hours of 2800 CPUs cranking, the job is ~80% complete (800k/990k tasks). From there, things start to nosedive: Spark stops using all of the CPUs available to it to work on tasks. With ~190k tasks to go, Spark will gradually drop from using 2800 CPUs to double digits (usually bottoming out around 20 total CPUs). This makes the last 190k tasks take significantly longer to finish than the previous 800k.

I could see as the job got very close to completing that Spark would be unable to parallelize a small amount of remaining tasks across a large number of CPUs. But with 190k tasks left to be started, it seems way too early for that.

Things I've checked:

• No other job is pre-empting its resources in YARN. (In addition, if this were the case, I would expect the job to randomly lose/regain resources, instead of predictably losing steam at the 80% mark).
• This occurs whether dynamic allocation is enabled or disabled. If disabled, Spark has all 2800 CPUs available for the entire run time of the job - it just doesn't use them. If enabled, Spark does spin down executors as it decides it no longer needs them.
• If data skew were the issue, I could see some tasks taking longer than others to finish. But it doesn't explain why Spark wouldn't be using idle CPUs to start on the backlog of tasks still to go.

Does anyone have any advice?

I'm new to HTML, CSS and I have been struggling to make this responsible grid with images. When you hover above them, text appears, but that's working fine. The problem is that once I resize the size of the screen, the grid stays the same and doesn't scale down to fit in. Also, once the screen width is less than 900px, the images go bananas.

Thank you in advance for tips!
