lamchob··on At Astra, failure is an option
Is there any information on their stance regarding the environmental impact of failed launches? The propellants alone are usually toxic, plus the amount debris of each failed launch. Did they factor these externalities into their cost as well? At 1 million dollar per launch and 250k$ manuracturing cost alone, I am not sure this part of their cost model.

lamchob··on Ask HN: How best to share papers in an open source repo?
You have two options:

* DOI Numbers, which uniquely identify scientific papers

* "Paper style" citations, with Authors, Title, publishing Venue and date. This is enough for any interested reader to find the sources

I would not recommend hosting copyrighted material in a personal repository.

lamchob··on Music Generates Feelings That Are Only Weakly Bound to the Music
World of Warcraft and Edguy's "Rocket Ride" album. I still listen to this band, but no other album has same "pull" for me.
lamchob··on Ask HN: What Is the Best University in Europe for MS in Computer Science?
I heard great things about both, Copenhagen and Saarbrücken
lamchob··on Ask HN: How to Approach Algorithm Studying?
Why are these the only options? Why can't you just know there is a solution, and know where you can look details up? Expecting to find ideal solutions on your own every time is tedious and taking time away from solving the actual problem you are working on.
lamchob··on MLIR Primer: A Compiler Infrastructure for the End of Moore’s Law
This works fine until it doesn't. See this paper (and the discussion) on why we need better tools: https://news.ycombinator.com/item?id=20301619

In short, you don't want to spend weeks on hand-optimized kernels, every time you want to implement a new type of layer for a large-scale network, or on an experimental target hardware.

lamchob··on Tesla Model 3 Cost of Ownership Slightly Cheaper Than a Camry
How would you drive in order to renew a clutch after 5 years? Usually a clutch lasts well beyond 10 years. Costs for break pads and and discs are also very low, unless you have ceramic break.
lamchob··on An 'Exosuit' That Boosts Endurance on the Trail
As the article highlights, the main target are military and medical applications.
lamchob··on Ask HN: What Do Hackers Eat?
How do cheese/butter and paleo go together (serious question)? I thought paleo is about non-processed foods. Which leads me to my second question: Why so few vegetables/fruits?
lamchob··on Ask HN: What Do Hackers Eat?
Mostly a sports-oriented diet. I try to maintain a healthy balance between carbs, protein(2g per kg bodyweight) and fat(1-1.2g per kg bodyweight). Meat usually once a week. Loads of greens, fruits, eggs, oats, cheese/yoghurt and nuts. Also whole-grain bread.

A little correction: Arnold was a real estate millionaire before he started doing movies. You can read/hear about it in the Tim Ferris Podcast/Tools of Titans book.
lamchob··on Ask HN: Ressources to Improve C++14 Skills
1. Software stack wise, I'm currently bound to C++14, however general advice on "Modern C++" is welcome, of course.

2. Haven't know about that SE, thanks!

lamchob··on Japan's Hayabusa2 probe makes second touchdown on distant asteroid
As GOES covers the US Coasts, and Himawari-8 Japan/East Asia/Australia, do you know of any geostationary satellites over Europe, from which the live images are available?
lamchob··on Show HN: Fist – Persistent Full Text Search and Indexing Server Written in C
Very cool project. Which algorithm do you use for indexing/retrieval?
lamchob··on V Programming Language released
It is not written in Go. Go was only used to bootstrap the first compiler. Newer compiler versions are written in V itself.
lamchob··on V Programming Language released
You are right in a scenario where testing is lightweight and quick. I'm sure this can cover a lot of use cases. However, If the testing/development itself involves heavy computation (large integration tests for example), there are diminishing return from quick but unoptimized compilation.
lamchob··on V Programming Language released
While it looks nice, it brags about it's compilation speed while simultaneously not offering any optimizations. If you want to have optimizations, C/C++ source-to-source compilation is required, which is slower by factor of 10. After that, a traditional C/C++ compiler runs the compilation/optimization, which again, costs time. What use is fast a compilation, if the resulting program can be slower by orders of magnitude?

Other than that, the design of the language looks nice and I will give it a spin at some point. Maybe I'll convert some HPC benchmarks to V and see how they perform.

lamchob··on Ask HN: How do I make using a computer distraction free?
A simple trick is to turn off the all the screens you don't need for your current work. Sometimes working with multiple screens is great, but during some tasks, the browser or mail program lingering on another screen can cause distractions. In my case, I often mindlessly switch to HN as soon as I start a compile/test cycle.
lamchob··on Ask HN: How do I make using a computer distraction free?
The deepmode extensions sounds great. But how does it know, what I am supposed to be working on? And how does it handle context switches? For example programming, then literature research.
lamchob··on Human Skeletal Muscle Possesses an Epigenetic Memory of Hypertrophy (2018)
Does this mean, that the use of anabolic steroids to build muscle at one point in time can lead to better performance years after usage? For example, a young athlete uses it in his late teens/early twenties to gain muscle and then lays off the drug for a while. Then he returns to competitive sports, reaping the benefits of the formerly enhanced hypertrophy without any means to test against it?
lamchob··on Ask HN: How do you use GitHub for LaTeX documents?
Visual Studio code, for example, has extensions for Latex. You can write the latex src in VS Code, compile and preview it. And since VSCode also supports git you can integrate your latex project and the repository in one workspace.
lamchob··on Ask HN: Has anyone tried using one of those posture-improving wearable devices?
How does kinesio tape help with weak muscles? Just correcting your posture occasionally won't do any good in the long run, either. This might "pull you into place" but no muscular strength is gained. If someone picks up a good routine to strengthen their weak spots, an improved posture will appear soon enough.
lamchob··on Ask HN: I need ideas to impress fifth graders with technology
Something we used for "tech-days" at our university, when 8th to 10th graders came to visit, was a robot following a black line on the floor, built with Lego Minsotrm. A set includes the base unit w/ two engines and some sensors, which should be enough to build a simple robot.

After we explained the algorithm how the robot can follow the line by keeping the line between it's to photo sensors, we let them implement and experiment on their own. The programming GUI is intuitive and works with function blocks that can be customized and linked together.

lamchob··on Google’s Cloud TPU Pods are now publicly available in beta
No, because many companies run their own clusters with no access to TPU hardware, or are not keen on shipping all their models + data over to google.
lamchob··on Ask HN: How do you not ruin your back (as an engineer)?
I second every comment on heavy lifting and do it myself on regular basis. But please, if you have never "lifted" before don't just waltz into a gym and start yanking on barbells. This can kill your back for good.

OP's Stronglift 5x5 is based on another program, "Starting Strength". Invest the money into the "Starting Strength" book by Mark Rippetoe. This book is "standart" in the powerlifting community and it's a treasure trove on body mechanics and "strength science". It will help you understand how to perform the basic barbell moves, based on body mechanics. For example, a lot of people struggle with mobility during squats. Don't push your depth with poor form, but ease into it, until you can go "ass to grass".

Edit: Record your lifts on a regular basis, to check your form. If you are unsure, /r/fitness provides form-checks.

lamchob··on Ask HN: What languages of the last 20 years are here to stay?
Does modern C++ count ( c++ >= 11) ? The modern standard changed a lot of paradigms of the language, like a multi threading aware memory consistency model.

In the domain of system programming and gaming C++ is still paramount. While Rust will be an alternative in the system domain, the gaming "core" is still created with C++.

Also, compilers. Most modern compiler projects (LLVM, TVM, Tiramisu, MLIR, Lift) are written in C++, and compilers are among the most long-lived software projects.

lamchob··on Ask HN: Most sustainable diet long term?
IIFYM may very well work for some individuals, as my post said: "be aware of what you eat and what your body needs". And junk food can fulfil the needs of very active individuals. But be careful when adapting diets from individuals with high amount of physical activity to someone with a sedentary job. This gets even more relevant, if recreational lifting isn't possible, as in OP's case.
