    Hey, I'm Trying to build the "Wine" Program from source code on macOS Big Sur but I'm getting this error from the terminal

    Posted: 01 Aug 2021 07:15 PM PDT

    So I wanted to use the newest wine 6.14 for M1 Mac support, however they don't provide binaries for it for whatever reason, so I decided that for the first time I would try building a program from source, I started this morning and have been trying for nine hours to get this to work, I've installed dependencies, I've installed the homebrew package manager, I've done several things and its been an absolute nightmare, now at the very final step where I finally get it to start building, right in the middle of the build process I get this error log

    clang: error: unable to execute command: Trace/BPT trap: 5

    clang: error: clang frontend command failed due to signal (use -v to see invocation)

    Apple clang version 12.0.5 (clang-1205.0.22.9)

    sh-3.2#

    This is the first time I've ever tried compiling something and its been a nightmare, I wish they just gave binary releases from the start, Any help fixing this error would be amazing as this appears to be the final step and I'm stuck

    I'm familiar with a lot of GUI Related things and tech in general but I've never touched the command line and everytime I have I just can't wrap my head around it, its very complex, I just want to finish compiling this or get a prebuilt wine from somewhere safe (But preferably build it myself since I've come this far)

    Someone please help :(

    Cry for help

    Posted: 01 Aug 2021 02:30 PM PDT

    Hi there. It can be an ancient history, but I must ask someone who has encountered this. I'm learning programming (have started from C) about a month. Some say that 4 weeks more than enough for learning syntax of the language completely and about this point I must start trying to make my own projects. But I haven't even finished my first textbook (Programming in C, by Kochan) and my very first course (Programming in C by Duke University). Is it OK or do I need accelerate my learning? And what can you recommend for one who want to become a computer scientist (except of going to college, because I have already had a Masters degree in Mechanical Engineering). I'm really appreciate any peaces of advice. Thanks in advance!

    Easter Eggs in Code

    Posted: 01 Aug 2021 06:08 PM PDT

    Just curious about what kind of "Easter Eggs" other people put in their code. For me, all the mocked data in unit tests is made up of characters and places from Hanna-Barbera cartoons. Needless to say, Yogi Bear and George Jetson have had some interesting times.

    What Is the Best Budget Laptop for Programming?

    Posted: 01 Aug 2021 09:08 PM PDT

    Anyone know of any good resources about 2.4ghz RF mouse dongle driver implementations?

    Posted: 01 Aug 2021 04:47 AM PDT

    I'm trying to get into writing driver code with Rust and am looking at RF peripherals like mice or keyboards as an entry project to research. My rough plan so far is to read through different implementations in the linux kernel and also run packet analysis on a bunch of different brands/generations of wireless mice/keyboards I have access to from a local electronics recycler I volunteer at.

    I've aggregated as many reference and Usb specification documentation that I could find(& ofc all the rust books), so I guess my question is if anyone has any resource recommendations that they found particularly helpful or any general brief "words of wisdom". Much appreciated!

    C# Windows Forms DataTable/DataTableGrid: exporting to Excel?

    Posted: 01 Aug 2021 07:52 PM PDT

    I am trying the following to try to export my existing DataTable to Excel.

    private void saveDataBtn_Click(object sender, EventArgs e) { try { StreamWriter sw = new StreamWriter(strFilePath, true); int iColCount = dataTable.Columns.Count; for (int i = 0; i < iColCount; i++) { sw.Write(dataTable.Columns[i]); if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); foreach (DataRow dr in dataTable.Rows) { for (int i = 0; i < iColCount; i++) { if (!Convert.IsDBNull(dr[i])) { sw.Write(dr[i].ToString()); } if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); } sw.Close(); MessageBox.Show("File saved to Documents."); } catch (Exception ex) { throw ex; } }

    The resulting file parses the Columns like this (and I assume rows as well but I did not even get that far yet, testing with blank tables at the moment):

    DataGridViewTextBoxColumn { Name=shotId Index=0 } DataGridViewTextBoxColumn { Name=Club Index=1 }

    Essentially doubling up each column. I am not sure what my mistake is because the columns (shotId, Club, etc) show correctly in Windows Forms. Any advice as to what I am doing incorrectly?

    Hey guys I have a question, I am a chef at a restaurant; I want to do a small project for my own past time to create a restaurant inventory program that

    - can save data (cost and names of products)

    - can cost out recipes and food cost

    - has easy UI

    - can output some data into document (excel or MS word)

    so My question is as a person who is learning programming with youtube and internet sources,which language seems to be the best choice? also I would appreciate recommendation on sources

    I want to make a simple script that if a second computer mouse is not used for x time, its input is ignored (Windows).

    Posted: 01 Aug 2021 07:15 AM PDT

    Super simple right? I'm actually not so sure how to have this script perform the best.

    I want two mice, one ergonmic for work and one that stays plugged in and I can grab and just start using when in game.

    I want the script to startup with Windows and run indefinetly. Maybe I'll have a sequence to listen for to renumerate the mouse again or whatever. But the main point is if the mouse is inactive for 5-10 minutes or whatever it'll start ignoring input from that mouse. This way I can just leave both mice on my desk and grab whatever one I need at the time. and my cat playing with the other one won't interfere.

    Problem is I feel like this is going to have some unforseen rammifcations with user privliges, incompatibility with certain programs or some other conflicts.

    Also I don't know the optimal language to do this in? Python seems off with the small chain I'd need to make with windows. C++? Is there a mouse library where I can just do if mouse.in(Lclick*2=true) use();?

    Visual basic...? Can I do it with a batch script? Is windows security gonna freak out if some uncertified script is watching my mouse with admin priviliges? My background is in circuit stuff and know enough programming to figure it out. I'm mostly looking for a nudge in the right direction.

    Or I am mistaken and this is a simple python script that takes 5 lines of code and won't have any issues. I imagine with the python script though I would just listen to the serial port and sleep it after inactivity. I'm not sure if that would virtually keep plugging it in and out.

    Anyone doing real work around bio-informed software architecture?

    Posted: 01 Aug 2021 09:44 AM PDT

    We see real-world architecture informed by biology all the time. The ML community, neural networks in particular, are real hot on bio-informed design. The other day I found myself referencing cellular mitosis when describing when to split microservices up.

    Is there anyone doing research in academia, writing blog posts, or actually practicing this in the field? If so, where can I learn more?

    I know the syntax of CSS, html but When I see a project I can't do it. Any Advice???

    Posted: 01 Aug 2021 11:26 AM PDT

    I know every syntax in css & html. I bought a udemy course,by a famous YouTuber. I couldn't approach design, I just become blank, don't know which attributes to write first. I can do guided projects but I can't design. So, I grow to hate CSS, entirely but I want to make money, & lean MERN stack. I really tried everything, but I can't do it, Help me out??

    Do you use a learning management system?

    Posted: 01 Aug 2021 07:31 AM PDT

    Hey guys! Hope you all are doing well. I am a programmer and sometimes I come across some new informative articles( new commands or ) or understand some nuances in docs of some tool I am reading up on. I have been bookmarking them in chrome or adding them to the reading list for future reading. But it's no good if I have to reopen something for casual revision. I have been wanting to create an environment where I can save these and when I open it it creates an atmosphere where I am motivated to add up to these lists( indirectly motivating me to read up more ) and it also makes it easier to find something I want to reread. I have tried using github but it feels like a lot of work. Have also tried saving them to Evernote but they get lost in my other work-related or arbitrary notes( there's added problem of purchasing storage ). If its cross-compatible on my devices( have a Linux laptop and iPhone), that's the cherry on top. Do you guys use something of this sort or am I just too selective. Thanks!

    Repeatedly querying large PostgreSQL dataset, what's the best implementation?

    Posted: 01 Aug 2021 10:57 AM PDT

    Hi, I'm repeatedly querying a large PostgreSQL dataset with a blanket statement .select() clause, instead of using a .json file so that I can update the dataset more easily via SQL.

    Reading from a JSON is super fast, near 0ms, whereas querying the data from SQL (about 136,000 rows) is more like 1500ms. How can I improve my query times?

    Unfortunately, the whole dataset is needed to perform tasks serverside.

    While planning to open source a portfolio website template what should be your considerations?

    Posted: 01 Aug 2021 04:18 AM PDT

    I am a mern stack developer and put a lot of efforts and took different courses to make my third version of website. Unlike first two versions, this version is highly customizable meaning, one can put in data hide widgets, easily configure Meta data etc.

    Though i have made it very much customizable, re factored the code and broke all the functional components full with comments and descriptions... This is to be consumed by someone who is supposed to know atleast an intermediate level html css and javascript. I am interested in knowing if what I put as open source template will be really helpful or will it make an impact?

    Additionally, what are the best practices i should follow to make it as simple as possible. Furthermore i am going to include a detailed Readme about customization and wanted some tips for that as well.

    Also I have built the template with react and sass and there are chances that someone who's unaware of sass may find advanced customizations hard to understand.

    Here's my portfolio: https://shivamsahil.web.app/

    I would love to have all sorts of feedback as this will be my first open source contribution.

    Does it matter which pointers I use to access elements?

    Posted: 01 Aug 2021 09:29 AM PDT

    I have a linked list and a vector of pointers to every element.

    Does it matter whether I use the links or the vector to dereference each object?

    In practice it doesn't matter. This is not where my code bottlenecks. But I reason the vector will be contiguous so those pointers will be cached and therefore faster to dereference. Is this reasoning sound?

    C#: Uploading a file to SharePoint using Microsoft Graph API

    Posted: 01 Aug 2021 05:33 AM PDT

    Im retrieving a file from one sharepoint folder (this works), but I want to also upload it to a different sharepoint folder, which is something ive been stuck on for quite a long time. Im having a hard time making anything out of the documentation so im wondering if anyone here have a good understanding of microsoft graph API.

    First, I'm fetching the file from sharepoint folder A based on its id:

    var fileName = await graphServiceClient.Sites.Root.Drive.Items[id].Request().GetAsync();

    then I try grabbing the actual contents of the file (.Content):

     var stream = await graphServiceClient.Sites.Root.Drive.Items[id].Content.Request().GetAsync();

    then I try to fetch Sharepoint folder B called "backups", (the one I want to upload the file to):

    var backupAsync = await graphServiceClient.Sites.Root.Drive.Root.ItemWithPath("backups").Request().GetAsync();

    Then I want to upload the file to this folder, and this is where im stuck. I'm pretty sure I need to use the .PutAsync<DriveItem>(stream) function to do this, but im not sure how.. Im not entirely sure if the previous code is the correct way to do it either because I dont get to test it, but using breakpoints I do at least know that I successfully grab the file from sharepoint folder A, aswell as the content of that file.

    Please ask if Ive made anything unclear. Any help is greatly appreciated!:)

    Python: Multiple ML Services via a single message broker system

    Posted: 01 Aug 2021 09:13 AM PDT

    Hi guys

    I'm a Data Scientist working in Ireland since an year. I've recently had a change of managers and the new management has allocated me software engineering tasks which I'm struggling with. I've been trying to get in the good books of my manager since a while now but due to a lack of expertise in a field, I'm not doing well. He has given me this task which I'm supposed to deliver within next week and am struggling really hard. So please if you could help me out. The task goes as follows:

    I have to design and build a robust system to classify fashion images (Fashion MNIST). The system will have a single client consuming a single machine learning service at a time. It does have to be robust, scalable and able to process requests asynchronously.

    (Note: This is not a REST API based system but rather one which can process requests in a non-blocking way and (theoretically) put the results somewhere else (like a database). This can be mocked by printing to the console)

    So I've broken this task into two smaller tasks-

    1. Build a simple FMNIST multi-class classifier (done)
    2. Build a unified API which can talk with Apache Kafka (for storing data), and GooglePubSub (for processing streams of clients)

    Now with task 2, I'm badly stuck as I've never designed a unified API, hardly have worked with Kafka or PubSub too. I was reading around how I could implement this and found some links where I saw the task can be done via this idea/approach or else this post would have been just with the first task and no clue about 2. I am requesting you guys if you can help me with this- maybe a method, code assistance, links or even some other subreddit where I can ask about this. Please

    Thank you

    Full data frame: https://www.dropbox.com/s/prbceabxmd25etx/lcb98cor.dat?dl=0

    Notice, for example, how every `V` value has a unique `Teff`, `logg` combination. Since they are on two different scales, I rescale things:

    BC.table %>% mutate(Teff.scale = rescale(Teff,Teff), logg.scale = rescale(logg,logg)) -> BC.table

    Now, let's say I have two values:

    input_Teff = 2300 input_log_g = 3.86

    If we imagine all the (Teff, logg) combinations as grid points, for a given input point, I would like to find the four points closest to that input point.

    point 1 (Teff1, logg1) point 2 (Teff2, logg2) point 3 (Teff3, logg3) point 4 (Teff4, logg4)

    then, calculate "distances" between my input point and the other points through Pythagoras (in this examples, three distances),

    (Teff1, logg_1) -> d1 (Teff2, logg_2) -> d2 (Teff3, logg_3) -> d3 (Teff4, logg_4) -> d4

    next, get in this example, the `V` values in the rows of these points,

    (Teff1, logg_1) -> V1 (Teff2, logg_2) -> V2 (Teff3, logg_3) -> V3 (Teff4, logg_4) -> V4

    And finally do a weighted average calculation

    V = (d1V1+d2V2+d3V3+d4V4)/(d1+d2+d3+d4)

    What would be a good way to do this in R?

    Programming and diet

    Posted: 01 Aug 2021 11:13 AM PDT

    I've been working for about a year now to improve my diet. The last thing for me to deal with are sugary drinks/sodas. I just can't beat them. I heard a chess player can use 6000 calories during a tournament, just by thinking so much.

    I've been getting headaches after going almost no-sugar, after a couple hours of working. And when I stop, the pain stops too. My brain is starved for energy, and seems like even eating like half a bar of butter doesn't help. I eat a lot of nutricious food already but it just doesn't work.

    Did you manage do ditch sugar? Is that even possible? Longest I survived was about 3 months.

    Assignment Operator inside if() condition.

    Hi Everyone... I was seeing the code for the Kth ancestor of a tree node and stumbled across this line.

    if (root->data == node || (temp = kthAncestorDFS(root->left,node,k)) || (temp = kthAncestorDFS(root->right,node,k))){}

    I don't understand why he put the assignment operator = (in temp = kthAncestorDFS( ))
    inside if() condition. And what it does exactly. I would be grateful if someone can clarify.
    Thanks in advance.
