    Would your advice to new starts be NOT to learn Java?

    Posted: 18 Dec 2020 06:45 PM PST

    I was in the ProgrammingBuddies sub earlier and someone asked a question about what language to learn and the top rated reply was basically: learn Python.

    They also specifically mentioned not to learn Java due to most jobs being fixing/maintaining old code. Is this true?

    I'm 3 years into a computer science course and have been taught Java all 3 years. Is it going to be essentially useless in the real world outside of fixing and maintenance?

    Should I be learning Python now?

    Is there a way to find out my original Instagram file name I uploaded?

    Posted: 18 Dec 2020 10:09 PM PST

    Hello, I uploaded a photo, I would love to know the name of the file I did originally uploaded to Instagram, is there a way to find this out? The photo I uploaded looks a bit blurry. I feel maybe, I uploaded the photo with the wrong quality size, but im not sure, and I would only know by knowing the file name I uploaded. I though maybe, a programmer/coder can help me figure this out, thankyou! if I can find access to this information from my laptop. :)

    Is this possible

    Posted: 18 Dec 2020 09:27 PM PST

    Info about myself: extremely beginner coder, sales rep for a software company, real estate agent, and a guy who has a question

    My question: would it be possible to set up a coding automation to where if someone put their house up on a real estate application (i.e. Zillow) my email automatically contacted the email tied to that specific account inquiring them about the listing? If so, would python or html be the best to use?

    This might be extremely basic, but I'm very new to coding and it's a program I'd like to code!

    Thank you for everyone who helps.

    How to deal with GNU Recutils files under Windows?

    Posted: 18 Dec 2020 06:08 AM PST

    As part of a possible customer project, a system based on recfiles (.rec) is to be moved to a windows server. The previous Linux computer has probably experienced its last software update in 2013.

    Linux, cygwin, wsl or "any kind of virtualizations" are not desired because the future admin is not familiar with them and won't become familiar.

    Sqlite etc. are no options, because the data should be editable with a text editor.

    This is all out of my scope.

    There are about 13.731 files with 96,3 GB.

    The system consists of some bash scripts and approx. 100 Python2 scripts. Up to now I've found out that the Python scripts run recsel, recins etc.

    The Python2 scripts should also be ported to Python3 and the whole system should be "improved".

    The whole documentation of the project consist of handwritten poorly legible notes on paper.

    I think Python2 -> Python3 will need some time but not impossible for me.

    Up to now I've found:

    https://github.com/OJFord/recfiles-rs, it seems to be very early dev stage.

    In the past I would not have started such a project because the risks are not really manageable but because of Covid19 the situation has changed.

    Are there any ports of recsel, recins, recdel, recfmt, recfix etc. which can be used natively under windows?

    Thanks in advance.

    Desktop bluetooth libraray

    Posted: 18 Dec 2020 04:06 PM PST

    I am building a mobile app that communicates with a bluetooth device. I would like to build a simple desktop command line app for communicating with the bluetooth device for testing purposes.

    I am looking for recommendations on a good library that is well supported with strong documentation, and is simple and straightforward to use. Ideally it would be supported on Linux, but I am also ok with something on mac or windows if its a great library. No language pref, just want something that is easy to use.

    Thanks for any suggestions.

    File upload function between frontend and backend

    Posted: 18 Dec 2020 01:23 PM PST

    Hey guys!

    Really need some help with this web-note-application project.
    I'm doing a note-application where you can input text but I want to be able to upload a picture as well into the note.

    I want to add a "Choose file" function and be able to upload a picture. But I really don't have a clue how to make it work.
    I'm using SQLite as my database, so I'm guessing I need a foreign key to connect the picture with the note. Also using VSCode(Javascript, html) so some sort of a function and other stuff I'm not sure about and then Java as well to connect it all together.
    Would appreciate any help or tips.

    Linking to the project in GitHub:

    How to create an online database?

    Posted: 18 Dec 2020 09:23 AM PST

    Hi programmers. I have created a database in Excel for some calculations, but I struggle with a few issues:

    1. The more data I put the slower (very slow) become my files, and I need plenty of data, infinite even.
    2. I dont know how to control access, its very delicate info, but I need a couple of people to have access to it only on my command.
    3. Sometimes I add samples from dates that dont follow previous order of insertion, but I do need to place them where they should be according to the dates, so its very annoying to search where they should go, id like to automate that process.
    4. I cant automate enough as I have to use different files because otherwise its very slow.
    5. I run some mathematical models with the data I use, and I have to update them every day, it takes me over an hour a day every update which makes it very slow as well.

    ​

    Now I have another issue in venturing to create an online database. There are like a million advices and a lot of them profit influenced, Im absolutely lost in here. Finally, I would happily delegate this project if it werent that my math calculations are very private, I cant grant access to anyone to my math. Can you help me understanding my best options?

Its the only thing that actually enters and outputs when i run the programm. Im attaching a photo that shows the output as well. I cant understand why the other values arent getting any value in it. Thanks for anyone that helps!

    Onoma ypallhlou = stackoverflow

    Arithmos mitroou ypallhlou = 0

    Typos ptixiou ypallhlou = 34

    Iperwries ypallhlou = 0

    Misthos ypallhlou = 0.000000

    Press any key to continue . . .

    Hard time at computer science classes

    Posted: 18 Dec 2020 03:29 AM PST

    So this year I started high school and I've always wanted to be accepted in my best school from my county that's specialized in computer science. So, my grades were really good and I got accepted. We started with C++ and I have a really hard time learning it. I've never programmed before, the closest I got to programming were some HTML courses and that's it. So we've got 2 months until the end of the term and I'm failing class. I've tried learning extra, asked some of better classmates to give me a hand. They did but I still have a hard time dealing with the tests and so on, they're really hard for me. Has anyone been in a similar problem and does anyone have some tips on how to get better and understand it easily, that would be greatly appreciated.

    How to keep components feeling responsive when update is delayed?

    Posted: 18 Dec 2020 12:21 AM PST

    TLDR: How do I handle controls that are slow to have their state updated?

    I have a web app that controls devices via http requests. My controls essentially send a command request, and then after that resolves, send another request to query the state of the device.

    Sending a command to a device and having that device accept the command and apply it can take longer than the 0.1 seconds (or whatever the imperceptible amount of time is).

    A more concrete example might be, say, a checkbox/toggle component that toggles LEDs on the device.

    My questions are: 1. What is a good way to handle this so that the user doesn't feel that their actions aren't accepted by the UI immediately? 2. Is there a standard name or standard terminology for this situation that I'm describing?

    Some approaches I've considered for the scenario of turning the LEDs on: 1. Update my toggle right away to the active state, regardless of the device state, and then wait for the follow-up query to either affirm that state or snap my toggle back to off. 2. Just wait and let the UI seem unresponsive until the follow-up query updates the toggle to the correct position. 3. Show a loading spinner over the whole page/container of all controls if any control is waiting for an operation.

    At the moment, option 1 seems best, but can we do better?
