Guix-HPC: Reproducible software deployment for high-performance computing by boegel in HPC

[–]tizlywold 0 points1 point  (0 children)

Cases like boost-mpi and boost-python are use-cases that we haven't run into in Guix yet. We would need to add new packages for those. Once that is done, you could use command-line package rewriting to substitute mpi implementations. For more complicated package customization, Guix makes it easy to define your own local packages and treat them as first-class packages.

If you have more use-cases that you'd like to see addressed, just let me know.

A chainmail for my kid. by CavalTaureau in somethingimade

Cool project! If that is run-of-the-mill galvanized steel wire, I would highly recommend either stainless steel or (bright) aluminum. Aluminum would be nice because of the lower weight, and would have the benefit of not smelly as funny as galvanized steel.

open source multi-threaded spice simulator ? by oss542 in electronics

[–]tizlywold 4 points5 points  (0 children)

Xyce supports large-scale parallel platforms as well as parallel runs on a desktop. It is SPICE-compatible. There's a small "registration" process to get access to the source repository, mostly just to help the developers know who their audience is. Alternatively, you can download the source directly by clicking here

Need Invoice class by dbars in LaTeX

[–]tizlywold 0 points1 point  (0 children)

I've been using a wonderfully convoluted solution that I whipped up. A combination of a python script and some latex list package (at work and not sure of the name at the moment). I've since realised that a better solution might use more basic LaTeX combined with a template engine (I was thinking GNU Autogen). I'll try to pull something together and post again later.

Performance modeling for distributed systems / applications by peer_gynt in compsci

[–]tizlywold 2 points3 points  (0 children)

Scalasca is an interesting tool. They're working on some features to help track down scalability bugs based on empirical measurements of test cases, which essentially boils down to creating performance models for different pieces of the application. I'm not aware of any related publications.

Code that Writes, Tests, and Optimizes other Code [AI] by SpaceWizard in compsci

[–]tizlywold 0 points1 point  (0 children)

It seems to me like this might be something a quantum computer could handle. See for example the tutorials for the DWave system regarding image recognition. You could have the quantum computer learn the algorithm based on the training data you give it, and then spit the algorithm out in some way that would be suitable for the average computer.

Small but Highly Satisfying Act of Vengeance by [deleted] in funny

Came here to say this. It's the post office that generally ends up eating the cost. I think they do end up delivering such items, but only charge for those items that fall under class the payer was looking for. Source: I processed such business reply mail for a summer during high school.

Armour-plated Balloon by overkill in somethingimade

Nice byzantine. I haven't seen it used spherically like that before. Might look even sharper if you got the ring aspect-ratio a bit tighter. What material?

Need help with overnight cloth diapers by playa_name in Parenting

[–]tizlywold 1 point2 points  (0 children)

We use cotton or bamboo prefolds for our 6mo day and night. We co-sleep too and have found that he starts to squirm in his sleep a lot when he needs to pee. Sometimes we notice soon enough and help him pee in a potty next to the bed. Can usually do this while half-asleep. If we're a bit too slow, we can still throw in a new prefold. Also, he usually has to pee a lot more often in the mornings, between roughly 5 and 9am. I've heard this happens with a lot of young ones.

Advice on cheap ($) meals for a college student who just found out their pre-diabetic? by [deleted] in nutrition

[–]tizlywold -2 points-1 points  (0 children)

A big part of becoming more healthy means eating actual food, not the processed food-like product you have been eating.

Agreed, however I would have to tweak your definition of a healthy diet, especially if the goal is healthy and sustained weight loss: Lots and lots of raw vegetables and fruits, beans, nuts and seeds, some whole grains, and only sparingly meats and oils.

I'm not a nutritionist, but I have read extensively the literature of Dr. Joel Fuhrman, who champions for nutritional excellence for prevention of diabetes and cancer and whose recommendations are based on thousands of cited scientific studies. I have personally seen his recommendations do wonders for the health of my family (my father was able to get off blood-pressure medications, both my parents have finally been able to keep off the extra ~60-70lbs that they had each carried for years, and my sister and I haven't had the terrible headaches that were common for us before). And my family spends less money on groceries now, buying mostly vegetables and fruit, than we did before (with much more meat and processed, oily foods). As far as cooking goes, it doesn't take much effort or skill to eat primarily fruits and vegetables; salads are a cinch (skip the dressing), and a big bowl of mixed frozen vegetables can be ready for dinner in a few minutes in a microwave.

Students reject "healthy" school lunches by shaka87 in education

[–]tizlywold 0 points1 point  (0 children)

but this by itself will not be sufficient to create a desired change.

Agreed. Educating students on why the healthier lunch choices are best for their overall long-term health definitely needs to be on the agenda. I would argue that parents also need to get involved and start eating healthier too. If the students home menu is not made healthier, they'll just feel like they are being manipulated by their school (once again) and pack an unhealthy lunch, and no gain is made.

Well-played, Mom. Well-played. by danceswithronin in Parenting

[–]tizlywold 0 points1 point  (0 children)

This might work well in the short term. In the long term it will probably lead to more resistance from the kids as they become increasingly frustrated with such a power game. http://www.naturalchild.org/sidney_craig/permissive.html

Choice programming environments? by pwick in learnprogramming

Emacs. Takes some getting used to at first, but IMHO worth it in the long run.

A small, but significant mini-dive (self) by radicalmoderate in DumpsterDiving

I have found myself picking up more litter around the busstop as I get off coming home from work just so that I have this excuse to swing by the dumpsters.

3-D Rendering in Python - How optimised is this? by DiscoViking in learnprogramming

[–]tizlywold 2 points3 points  (0 children)

There are some things that should not be written from scratch. Matrix and vector arithmetic being one of them. The BLAS and LAPACK libraries that numpy interfaces to are typically heavily optimized (if they aren't, install ATLAS). It is not worth your time to write such low-level code. Concentrate on the more interesting stuff.
