<p>If you're a man that didn't sign up between 18 and 25, you permanently lose student aid in most states along with federal employment eligibility. Some even ban getting a driver's license.<p>In practice, it's young men of lower socioeconomic statuses that are failing to register. This is due to lack of knowledge or presence in the system more than conscientious objection. e.g. Prison or being homeless.<p>Many choose to get their life together in their late 20s and 30s, only to find out they <i>can't get job training or student aid.</i> These are legislatively mandated penalties and cannot be unilaterally removed by the current administration.<p>There's no clause for late signups outside of that window.<p>The only way out is to prove that you didn't know, which is difficult. There's about 40,000 people a year requesting the paperwork to appeal their loss of benefits.<p><a href="https://www.usatoday.com/story/news/nation/2019/04/02/failing-register-draft-women-court-consequences-men/3205425002/" rel="nofollow">https://www.usatoday.com/story/news/nation/2019/04/02/failin...</a></p>

<p>The advice I have as someone who also pushed boundaries is to be more creative next time.<p>The school will hate you no matter what. But this project doesn't appeal to VCs because social networking isn't trendy anymore.<p>Try doing something fresh with AI.<p>Example: the founder of Cluely got expelled from Columbia for creating an AI to cheat at LeetCode-style interviews.<p>He also spends his time posting what some call unprofessional engagement bait on social media. However, he just had a $15 million Series A.</p>

<p>I don't understand why you're downvoted. Many of my 2025 graduate friends are seeing this problem.<p>Unlimited token-based usage of Claude Code is not in the budget for many students and employees.<p>At the same time, companies are demanding experience with these tools.<p>This is stratifying the industry. I have many talented classmates that can only use free GitHub Copilot. They're likely being screened out in favour of rich classmates with $200/month Claude subs.<p>As a result, they'll be more likely to get low-paying jobs that don't provide access to top-tier AI tools and the effect will compound.<p>I think this'll be even worse as Claude phases out subsidies.<p>If $2000/month subscription to Claude for 4 years of university is the minimum required for a Big Tech job, this field is going to become law/finance levels of cliquey.<p>Nobody is talking about that because it's bad for both AI booster and skeptic narratives but it's happening.</p>

<p>I love how OP directly borrowed the plot of <i>The Social Network</i> by scraping the campus directory for a student rating system. And <i>somehow</i> it's playing out in the exact same way.<p>> I had scraped data for all students at IIT Delhi, and made a profile for all of them.<p>> anyone could make an anonymous account, and then comment anything on anyone's profile. Each profile also had 4 fields, where you could tag anyone, in the "has dated", "crushing on", "crushed on by" or "haters" category.<p>> he told me, take the site down or you WILL face DISCO, so again I was like sure, I dont mind it (I was just gettting reminded of Social Network lmao)<p>> also at one point i literally said the social network dialogue, " I feel like i deserve some recognition from you guys"</p>

<p>I've enjoyed this, honestly.

<p>Highly suggest connecting with one of the lead developers, Charles Dang/Vultraz, if you have any C++ jobs in the USA.<p>He's been a developer on Wesnoth since 2012 but only graduated university in 2024. Unfortunately, it's been an absolutely brutal market for new graduates. Even if you're a maintainer on one of the most popular OSS C++ projects on GitHub.<p>I can't recommend him enough.<p>edit: LinkedIn <a href="https://www.linkedin.com/in/charles-dang-10994b1b4" rel="nofollow">https://www.linkedin.com/in/charles-dang-10994b1b4</a></p>

<p>I've spent US$16 700 last month. I made an autoscaling K8s cluster for distributed compilation/caching on a large C++ project. I also heavily modified the build system to use a forked version of `siso` compatible with our environment.<p>That meant we can go from 17 minutes on 32 cores to 5 minutes on a few hundred. And because it's distributed compilation we don't have to provision each developer with an overpowered build system they won't be using most of the time.<p>It could also eliminate our CI backlog because autoscaling. Over a few hundred engineers building this codebase this probably a few thousand hours of waiting a week.<p>This took me about 2 weeks as someone who graduated 9 months ago. Most of the tokens were spent in several hour long debugging sessions relating to distributed systems networking and tracing through gRPC logs because the system wasn't working until it did.<p>I think I'd need several years of experience and 6 months as a full time engineer to have accomplished the same thing pre-AI.<p>Since I work at a semiconductor company near Toronto there's nobody around with the distributed systems experience to mentor me. I did it mostly on my own as a side project because I read a blog post. I literally wouldn't have been able to complete this without AI.<p>I'm sure the actual solution is <i>terrible</i> compared to what a senior developer with experience would've created. But my company feels like it's getting ROI on the token spend so far even though it's double my salary.</p>

<p>> No one is going to not buy something because it is kosher. But if paying a thousand dollars a year to put a small circle-u symbol on the back of your box can increase sales by 1% among observant Jews, most companies are going to do it.<p>Contrary to perceived politics, many Muslims will eat kosher food because it's a superset of halal rules (excl. alcohol).<p>It's a globally consolidated certification through organizations like the Orthodox Union. This is unlike halal which is local and has many scammers offering to pencil whip compliance. This means many Muslims will <i>prefer</i> kosher to "halal" food to avoid due diligence on the certification agency.<p>To tie this into age-verification, companies and ecosystems will use the strictest method that makes them globally compliant. Consumers will prefer that convenience even in the presence of intense political beliefs.<p>A bank that uses seamless OS-level age checks everywhere will win against one asking manually in the jurisdictions it isn't required.</p>

<p>> each compilation unit will end up with its own copy of templated function, which creates extra work, code bloat etc.<p>Yes, that's what causes the parsing bottleneck. Unity builds don't need to create multiple copies of templated functions.<p>C++20 modules could fix that because the function is parsed before substitution. Tbd on if that optimization works yet, I tried it on Clang 18 and it didn't.<p>> But the linker is single threaded and notoriously slow<p>I think most linkers have parallel LTO and `mold` provides actual parallel linking.</p>

<p>If you're doing single-core builds, you will get impressive speedups from unity builds.<p>This is because C++ compilers spends a lot of time redundantly parsing the same headers included in different .cpp files.<p>Normally, you get enough gains from compiling each .cpp file in parallel that it outweighs the parsing, but if you're artificially limited in parallelism then unity builds can pay for themselves very quickly as they did in the article.<p>C++20 modules try to split the difference by parsing each header once into a precompiled module, allowing it to reuse work across different .cpp files.<p>Unfortunately, it means C++ compilation isn't embarrassingly parallel, which is why we have slow buildsystem adoption.</p>
