I never knew what a difference good pants can make. I usually just bought my pants from H&M/other retailers or Amazon. I usually bought what I considered good value pants for like $30-80. I then, out of curiosity, bought pants that were 2-4 times as expensive (~$150) and it really made a difference. I never really liked the pants I had… they never fit right… they felt very uncomfortable. The new pants I got about 2 years ago (the more expensive ones) were very very different. Very comfy. They also had a lot of nice features that I never knew I needed but that I now want by default…

- A button that just "clicks". Most pants I usually owned had a traditional pants button. Those more expensive ones had buttons that just "clicked". Away goes the worry about a button falling off while you are on the go. - Pockets with hidden zippers: My pants have pockets and in those pockets are smaller pockets with a zipper. Perfect to store things that are small and easily lost.

There are more "features" but those are the important ones. The most important feature is just the material that is used. I barely feel it. Also the company that makes those pants makes other things as well. I ordered a lot of cloths by now and the amazing thing is that everything they make fits me perfectly. I don't know how they do it… When I usually buy pants I have to try on like 10 pants to find one that fits. Even if I pick the "correct" size.

umpalumpaaa··on Show HN: I built a local-first daily planner for iOS
there are a lot of apps that do this though… eg. git tower. Sketch. Etc. Not saying that I like it or anything. Maybe its the combination of local first + an app that seems to be trivial (I am sure it was not but if you hear "daily planner" I think its reasonable to assume that its less complex than a git client and/or an app like Sketch).

First hand knowledge: ERGO and MunichRE both have a lot of cobol still doing the core business. You will most likely never run into the system because they just run batch jobs - sometimes configured via a “nice” web UI… you configure your job, submit and the next morning you have your report… that’s why you never actually see COBOL.

Yeah its just a shame – the photos look so professional and clean otherwise.

umpalumpaaa··on Shai-Hulud malware attack: Tinycolor and over 40 NPM packages compromised
Most big tech companies maintain their own NPM registry that only includes approved packages. If you need a new package available in that registry you have to request it. A security team will then review that package and its deps and add it to the list of approved packages…

I would love to have something like that "in the open"…

I once had to go through a SWIFT certification and it was a nightmare… They make you jump through so many rings… They make you buy hardware from them (for their certification runs), their documentation is awful. Their test environment is awful (no logs, no clear error messages, etc). Sadest time of my life.

umpalumpaaa··on Are OpenAI and Anthropic losing money on inference?
No. But training an LLM is certainly very very expensive and a gamble every time you do it. I think of it a bit like a pharmaceutical company doing vaccine research…
umpalumpaaa··on Maintaining weight loss
I found loosing weight was a lot easier than maintaining weight. When loosing weight you have a lot more wiggle room… As long as you are spending more calories than consuming you loose weight. It does not matter if you have a deficit of 20kcal or 200kcal.

Maintaining your weight requires one to have 0 deficit in either direction.

umpalumpaaa··on LLM Inevitabilism
Yeah its not. It is actually really good and I bet they make a ton of money.
umpalumpaaa··on There is no memory safety without thread safety
100%.

Some more modern languages - eg. Swift – have "sendable" value types that are inherently thread safe. In my experience some developers tend to equate "sendable" / thread safe data structures with a silver bullet. But you still have to think about what you do in a broader sense… You still have to assemble your thread safe data structures in a way that makes sense, you have to identify what "transactions" you have in your mental model and you still have to think about data consistency.

umpalumpaaa··on LLM Inevitabilism
It clearly is a 100% custom UI logic implemented by OpenAI… They render the products in carrousels… They probably get a list of product and brand names from the LLM (for certain requests/responses) and render that in a separate UI after getting those affiliate links for those products… its not hard to do. Just slap on your affiliate ID to the links you found and you are done.
umpalumpaaa··on LLM Inevitabilism
ChatGPT also makes money via affiliate links. If you ask ChatGPT something like "what is the best airline approved cabin luggage you can buy?" you get affiliate links to Amazon and other sites. I use ChatGPT most of the time before I buy anything these days… From personal experience (I operated an app financed by affiliate links). I can tell you that this for sure generates a lot of money. My app was relatively tiny and I only got about 1% of the money I generated but that app pulled in about $50k per month.

Buying better things is one of my main use cases for GPT.

umpalumpaaa··on Interstellar Flight: Perspectives and Patience
"A 0.1 µm interstellar dust grain (≈10⁻¹⁴ kg) striking a spacecraft at 0.2 c carries ≈20 J of kinetic energy—millions of times below “tens of millions of joules.” Reaching 10–50 MJ would require a ≈0.14 mm grain (≈10 µg), vastly rarer than ordinary dust, and even that impact equals only a few shots from the world’s highest-energy laser (~2 MJ per pulse), not “hundreds.”"
umpalumpaaa··on Writing N-body gravity simulations code in Python
Every time I see anything on the N-Body problem I am reminded by my final high school project... I had 2-3 weeks of time to write an n-body simulation. Back then I used C++ and my hardware was really bad (2 GHz single core CPU or so…). The result was not really impressive because it did not really work. :D But I was able to show that my code correctly predicted that the moon and the earth would eventually collide without any initial velocity given to both bodies. I went into this totally naive and blind but it was a ton of fun.
umpalumpaaa··on How University Students Use Claude
I am not sure all humans work the same way though. Some get very very nervous when they begin to struggle. So nervous that they just stop functioning.

I felt that during my time in university. I absolutely loved reading and working through dense math text books but the moment there was a time constraint the struggle turned into chaos.

umpalumpaaa··on First-of-its-kind trial enables paralysed man to stand via stem cell injection
Immunosuppressive or immune modulating drugs are not that bad. Usually people can take them without too much issues. Yes: Your risk for cancer increases a bit and you have to be careful to not get sick etc. but overall its not that bad.

Most people who have autoimmune diseases also need to take those drugs usually for life – (smaller dosages but still)...

umpalumpaaa··on C stdlib isn't threadsafe and even safe Rust didn't save us
I am not sure making things safe by default is a good idea. This always comes with a cost. Thats also the reason why basic data types (array, dictionaries, etc) are generally not thread safe… because its usually not needed or handled on a much higher level.

Its a different story for languages/environments that are supposed to be safe by default and where you have language features that ensure safety (actors, optionals etc) but not for something like libc which has a standard it has to conform to and like 100 years of history.

umpalumpaaa··on C stdlib isn't threadsafe and even safe Rust didn't save us
The man page says:

> POSIX.1 does not require setenv() or unsetenv() to be reentrant.

A non-reentrant function cannot be thread safe.

In general (for POSIX, libc and many other libraries: if the docs do not explicitly say "this function is thread safe" they are not).

umpalumpaaa··on Apple Passwords’ generated strong password format
In my experience, changing the password at big corps usually locks you out and requires a call to IT. I had a success rate of about 50% when I had to change passwords. It was the most frustrating thing...

"Oh yeah your password change properly is not synced to all servers yet. Just wait and try again later"

"Oh you tried the new password too many times while it was not synced yet. Your account is now locked. You need a manager approval to unlock your account."
