| Legally distribute a tool used for code signing Posted: 06 Aug 2021 07:08 PM PDT Is there a small tool that can be legally distributed within a commercial package which can be used to code-sign executables? SignTool is used everywhere but is part of a large SDK package by Microsoft and I want to avoid someone from having to get that SDK as a pre-requisite to ensure they can sign exes. The tool would:

| How to combine CSS, HTML and JS? Posted: 06 Aug 2021 06:26 PM PDT I am making a website and I wanted to make a sign up/in form. I found one on Youtube a guy made that form. I liked it, so I wanted to copy it as he left the full code in the description box. Now, how do I add all code to the website to make it as a page when someone clicks the SIGN UP user page to either make or login to the account. I have watched multiple videos about how to link all the code together, but I still only get HTML code presented and not JS or CSS. In the chrome just the basic HTML text code. So my question is how to put them all together and add them to my sign-up page. I also have listed the link for the guy's video and the code so any of you might need it. Would be appreciated.

| Opinions on custom top level domains for a web dev portfolio website? Posted: 06 Aug 2021 09:11 PM PDT I am about to finish creating a website for my portfolio. I was considering blockchain hosting for it, which would enable me to buy a custom top level domain (websitename.bruheggplantemoji for example). For the most part, how do you think employers would feel about using a custom top level domain (assuming it was just my name and not anything crazy) for a portfolio website? Do you think they would like it, think it's unprofessional, prefer me to use a more common top level domain, or not care at all? I know it will probably vary by employer, but I would like your opinions. [link] [comments]  | ||||||||||||||||||||||||||||||||
| How to convince boss to let me take on more work for more pay (vs hiring another programmer) Posted: 06 Aug 2021 08:41 PM PDT Hey all. I took up a very low paying job $20 an hour because I was in a weird spot in life, I was only staying in a place for 6 months and figured might as well see what was up. Ironically, this is the best job I've ever had. I previously worked as an SDE at Amazon, which wasn't that bad but this job just rocks... except the pay ofc. Today I learned that the boss was wanting to hire 2 more programmers, because the amount of work was getting to be too much. I know it is getting to be too much because the way the projects are managed just has so much time being wasted. People working over each other, people waiting for confirmation on things that shouldn't need confirmation and general laziness (I'm guilty of this too tbh lol, but eh at $20 an hour...). He seems to think more $20/hr college students will solve the issue, but the issue is the technical debt coming from hiring generally inexperienced programmers without teaching them (something I'd be willing to do). Through luck and personal connections, they basically got a client that writes huge checks for "development" which consists of basically making custom javascript web pages that hook into salesforce. Not that complex at all, but has a ton of potential to get better. The issue is there's already a "lead" developer who is not a programmer by trade. He picked it up, which is super respectable, but you can imagine someone that's only been programming a year, organizing big projects... you can see how a 5000 line .py file for flask might pop up lol So much time is spent patching up problems related to this 5000 line .py file, like probably hundreds of hours at this point. I've offered to just rewrite the whole thing and actually have some encapsulation... but lead dev says its "not worth it because this is working" and I don't want to step on toes. Just realized I'm ranting, so I'll cut to the chase. TL;DR Boss wants to hire 2 more programmers. I was planning on leaving the company soon but realize that I could easily do this work instead and would love to continue working for the company and just get the comparable salary. The issue is the lead developer probably doesn't even make that much and I don't know to to suggest I should get paid 3x as much as the other developers ($20/hr). How should I go about this? This is my first start-up, I love it compared to corporate jobs I've had, despite the 3-4x higher salary. I really can't justify getting paid this little for much longer though. Thanks!

| Posted: 06 Aug 2021 08:41 PM PDT I have made a working native Win32 splitter (got a little help from another Redditor). The problem I have having is that when I go up and down there is a lot of flickering put the window still move as intended. The major problem though is when I try to resize the window to make it bigger. When I go to resize nothing stays in it's original position everything moves. Can someone take a look at my code please? If you are compiling with visual studio make sure to add these to the linker "Comctl32.lib, UxTheme.lib" [link] [comments]  | ||||||||||||||||||||||||||||||||

| How can I somewhat efficiently represent computer memory as an immutable data structure? Posted: 06 Aug 2021 06:18 PM PDT I am writing a Y86-64 implementation (a simplified version of X86-64 from CSAPP by Bryant and O'Hallaron). I am writing this in Haskell. One of the main goals of this project is to make the implementation pure so therefore I must use an immutable data structure for my memory representation. A correct but impractical representation would be an array of a couple million bytes. The size of a processes memory is not defined for Y86-64 (please let me know if this is defined for X86-64. Is it OS dependent?). Therefore it is up to me to decide how much memory a process gets. I have been considering using 5 different arrays of bytes for the process memory, in a manor very much like a segmented memory model. One array for the code, one for initialized global data, one for uninitialized global data, one for the stack and one for the heap. The size of the first three arrays would be static, and then I could dynamically grow/shrink the stack and heap. This method is more space efficient than my first idea, but it is less natural, has more moving parts, and I will have to deal with the case of going out of bounds on one segment and needing to read from a different segment. I will also not be able to use indices as addresses as I would be able to with one giant array. Haskell does provide vectors which are much like immutable arrays however they are not space efficient at all. I believe that each cell holds 5 word size pointers plus the data being stored. I am brainstorming and this post is an extension of my brainstorming. Any advice will help me. [link] [comments]  | ||||||||||||||||||||||||||||||||
| Posted: 06 Aug 2021 10:12 AM PDT My boss right now is having me go through updating all of our dependencies in a project updating them for security, and then updating subsequent dependencies that need updated for compatibility with the other dependencies. My question is: would it not make projects way more portable and easier to collaborate on if, instead of a requirements.txt and virtual environments for dependency management, and blah blah blah, if you, rather than importing a dependency, just copied the entire dependency, put it as a new file in your project, and then reference it using relative paths? Of course it might make updating take a little longer, and you'd still have to give proper credit and what-not, but wouldn't it make your project way easier to collaborate on?

| Matching problem with multiple matches Posted: 06 Aug 2021 09:38 AM PDT Does anyone know of any resources/existing algorithms that solve for matching up several pairs of people, sort of similar to Stable Marriage Problem solutions? I have a dataset where each person has compatibility rankings with everyone else. Given those rankings, I want to create a specific number, let's say 3, matches for each person. The goal is to find a set of matches that is "best" for the group as a whole. I can elaborate on what best would be if needed. If User 1's most compatible person is User 3, it is likely, but not certain at all, that User 1 is high on User 3's compatibility list as well. The data looks like this:

| Posted: 06 Aug 2021 04:04 PM PDT I'm rolling my own HTTPS server and found this useful site. https://webencrypt.org/illustrated-tls/ Under 'Server Certificate', it says the server certificate contains the 'public key used by the server.' Then looking at the Server Key Exchange Generation section, the public key used by the server is not just different, it's using a different key exchange protocol. What public key is in the certificate? Where is it validated? Is the server using ephemeral keys for key exchange? [link] [comments]  | ||||||||||||||||||||||||||||||||
| I'm about to learn programing (so help me decide) Posted: 06 Aug 2021 02:10 PM PDT I have nothing to do with programing at this moment as I speak, but it'll soon change. I'm going to pay for full academy course and gonna be learning programming. It'll start after 2 weeks from now. Right now I just gotta decide which language I want to learn - either Python or Java. Could u please tell me some advice maybe before I get into it? Any info about it is very VERY valuable for me. I already asked tips from many people, but still extra advice is always nice. Some people said it's useless to spend money on academies, some said academy courses were very valuable for them, others said just use YT tutorials or udemy etc. But I've already made a decision and I'm going to pay for the course in academy, plus it's a lot easier for me when I have a teacher who shows me 10-15 times how to do it, until I master it myself. But before I move on, PLEASE give me some advice which one should I choose to learn for a start? Python or Java? [link] [comments]  | ||||||||||||||||||||||||||||||||

| Posted: 06 Aug 2021 09:49 AM PDT It has always been a bit confusing to me when I have to write unit tests for some methods. but some methods are deadly simple, and 1) I don't know if there's gonna be any value writing them; 2) writing tests for them is almost the same writing the same logic but in unit tests. (I'd love to know if there's any existing principles about what to test or what not to test.) here are a few example: e.g.1: ``` public static Object OBJ_A; public static Object OBJ_B; public Object getByFlag(boolean flag) { return flag ? OBJ_A : OBJ_B; } // and the test would be something like, basically repeat the logic in tests assertEqualsObj(OBJ_A, getByFlag(true)); ``` e.g.2: ``` public List<Object> filterObjects(List<Object> objects) { // same can go with simple reduce, map as well return objects.stream().filter(e -> e instance of Animal).collect(Collectors.toList()); } assertTrue(filterObjects(List.of(new Truck())).isEmpty()); ``` e.g.3: A React example ``` // this like e.g.1 are both just testing the framework/ language we are using const HeadingComponent = () => <h2>Hello Heading</h2>; expect(<HeadingComponent />).contains('h2'); ``` e.g.4: ``` Class Example { public void methodA() { ... } public void methodB() { methodA(); } } // tests Example e = spy(new Example()); e.methodB(); // verify that methodA is called once when calling methodB verify(e.methodA()).time(1); ``` I think for the first 2 examples, I would still write tests if the condition becomes more complex. so I think it's the complexity of the condition that matters. but for e.g.3 and e.g.4 . It feels like to me we are just testing the framework/ language itself. If we even need to write tests for those, we will then have tons tests to write.

After pressing F8 and trying Safe and then Debugging Mode, neither wanted to load a couple of times. In Safe Mode, it did give me a list of files it loaded and then just stopped.

| How to check if public static string method is equal to something ? Posted: 06 Aug 2021 07:24 AM PDT Hi. I wonder if I can check the value of public static string method in if condition. The code of the method is here : method ReadFromLine (github.com) The method returns one value, currentAttributeValue (It can be either a string or a number). This is what I tried : if (ReadFromLine(reader.LineNumber, "hodnota", "hodnota_nt").Equals("neg.")) (or instead of Equals I tried : == "neg.") But this will never evaluate as correct, and I don't know why. Any ideas how to solve it ? My program is reading specific values from XML file and then putting them to Excel. There is the reader code : Reader (github.com) If you have any questions, feel free to ask. [link] [comments]  | ||||||||||||||||||||||||||||||||
| Are there different kinds of "scaling issues" or is there only one? Posted: 06 Aug 2021 01:08 AM PDT I had this coding assignment where I was given a scenario of a system with scaling issues (among other things). I was asked what else I'd like to know about the system. My mind blanked and I just regurgitated whatever I thought I knew about scaling. I asked - are these scaling issues with regards to peak-load or volume? Scaling up or out? I think my brain was thinking scaling wrt to hardware. Anyway, I'd like to ask you guys - did my question even make sense? Is that something I should be curious about? [link] [comments]  | ||||||||||||||||||||||||||||||||
