I used Samsung ARM Chromebook from 2012 for Java development. 2GB of RAM was enough to run couple of Eclipse instances. Properly configured memory compression made it possible.

That reminds me about early Fortran where everything was statically allocated including local variables and function return address. To simulate data structures one used arrays of various dimensions. Effectively array indexes where handles.

I can agree with that when comparing with plain C code. But reference-counting in C++ and Objective-C leads to exactly the same problem as with managed code. What saves C is that reference-counting there leads to a lot of boilerplate and bu

Also memory-safe languages with GC allow for simpler API and design. That in turn gives more time to think on errors in logic.

OpenSSH focuses on security and correctness, not performance. That allows to use simple idiomatic C. Still, as with Chromium, it does use process isolation to mitigate memory-safety bugs.

Chromium initial design was a very simple main process and few untrusted relatively fat processes for web pages each holding set of tabs. That could have worked with C++. However the need for site isolation, performance considerations and h

My impression is that Linux tries to give sysadmins tools to secure existing binaries with containers, secomp, syscall filters etc. OpenBSD focuses on securing things at the source level. Hence all the compiler tricks to mitigate memory saf

I wonder what is the reason for that? I doubt Apple code quality dropped significantly. Is it simply because more people started to look for vulnerabilities? Or was it because better tools to discover the bugs became available?

For me the biggest plus of UTC is that the values do not jump back in time in spring during the switch to day light saving times. Surely there are tools that allow to compare/sort time properly as long as there is TZ in the date, but i

The article rises a good point that emergency universal income is better than paying companies to keep people at work as done in many European companies. Post COVID world will require different jobs and many companies will cease to exist so

The book “Medical Nihilism” by Jacob Stegenga similarly covers the subject of hiding negative results, how even apparently carefully performed double-blind studies can be manipulated to favor pharmaceutical companies and how those companies

Return from the stars is my favorite. In a some sense it is still about how to deal aliens that we cannot understand, it is just the aliens is future society.

Among film adaptations of Lem’s works I like “Inquest of Pilot Pirx” from 1979 the best. It is rather off from the story, but at least it portrayed Pirx close to how I imagined him.

Git works nicely on Linux for Chromium with over 540K files spread across a few modules. On Mac and Windows it is kind of tolerable, but with git status taking 5 or more seconds, I started to use “git status directory” to get more instant f

Optical laser is rather inefficient at converting electricity into optical energy. Surely there are some low-powered diodes where one can get over 50%, but for powerful lasers efficiency like 1% is a good number. Consumer microwave ovens o

In Wuhan the infection rate went down only when they started to place any person who required quarantine to separated buildings. This points out that perhaps transmission across apartment building is significant.

SGX is about making arbitrary general purpose computations encrypted and inaccessible from the rest of the system. Thus it cannot use a crypto chip with fixed set of secure operations.

The correlation comes from low scores. Moreover, above 70 IQ is not even well correlated with itself as variability between results for the same person is like 20%.

The observation is that above roughly IQ 70 the test is not even correlated with SAT scores. And below 70 one does not need a test to see that.

When I studied physics 25 years ago in Bergen University in Norway Emacs was used by most stuff and students. Most of the usage was writing papers/thesis in LaTex followed by scripts for Matlab or similar systems.
