Somewhere on HN in a similar discussion a bluetooth stack engineer showed up and explained that the entire bluetooth comms stack is a Rube Goldberg house of horrors, so this really no surprise. And then there are the bufferbloat people who

We're in the midst of an unprecedented effort to time-shift wealth/money/value. Never before in history have we attempted to store wealth at this scale for things like retirement. In a world that was continually growing at a

Neat! Perhaps you could run this against H2 (I’m a maintainer). Although best to run against our current master, release is a little old.

Actually, no, I havent had an out-of-the-box working VNC for more than 5 years now, through various Ubuntu LTS releases and now Fedora. Every single one of them has had various annoying bugs that would not have survived decent QA. But your

that sounds like a case where it would be best to pipe stuff into julia and read the output. or hack up a daemon-process thing where you can start it up outside the loop, then call it inside the loop

The thing about using these kinds of tools (IMO) is that it is effectively a giant flag waving at the NSA saying "hey: over here, I'm doing something worth keeping a close eye on!" And once they get sufficiently interested, t

Not with the ongoing Wayland, Systemd, Pipewire, etc, rewrite-from-scratch work. e.g. I don't have working VNC server at all on latest Fedora, with either X11 or Wayland, and no sign of it being fixed anytime soon. And that is just one

I tell all my younger friends to go to varsity and to take as many theory heavy courses as possible. Obviously, YMMV, but I find absorbing any theory-heavy knowledge alongside my day job extremely hard, whereas I can very easily more practi

The default size is in fact optimally sized for "normal" Java applications, which frequently do very little with string buffers, or use them for small tokens or numbers. Source: mailing list discussion with one of the Sun devs.

This seems like a natural outflow of a company design process that (a) prioritizes security highly (b) prioritizes regular users over developers (c) does not allocate sufficient resources to the product to thoroughly cover all the bases (d)

It does not scale beyond rather simple programs. Text has much higher information density for the specific problem domain of representing programs.

v8 has the ability to snapshot a program just after it loads, but before it executes. If you snapshot after doing some kind of warmup, to trigger the right optimisations, you get something that should fire up ready to go, which is probably

fellow saffer here, good for you!

Given the insanely vitriolic level of personal criticism leveled at the systemd people on an ongoing basis, some degree of glibness is an unfortunate byproduct. How about we give them some benefit of the doubt, that they are mostly trying t

Clearly other people are smarter than me. I'm not that smart, and I'm a parent, so I take quite seriously the act of choosing which stuff I need to learn to use. If you're young and smart, that probably doesn't matter, y

I don't have the mental space to waste filling it with details of another Google communication product they are going to discontinue in a year.

note that the new graphics backend is still optional, and exists alongside the existing backends.

What is wrong with Swing? Coz I use it every day, and despite many little deficiencies, it still compares well to other cross-platform toolkits.

I wrote a clang plugin to look for opportunities across a 10M line codebase and there was surprisingly little to be found. Why? Because on 64-bit Linux, the current C++ ABI mandates quite large alignment, especially once you are embedding t

that hides a lot of detail. Like just chopping off a leg instead of spending a 12 hour operation and months of physiotherapy to save it. Letting people die from chronic conditions instead of managing them. Letting old people die, because th

Hmmm, I would think the massive sucking dry of the aquifers by farms and cities using massive pumping schemes would be more to blame. Once you pull the aquifer down far enough, the surface starts to dry up, plants stop holding the soil toge

Unfortunately, it only gets marginally better. It is still way too painful for regular people to use.

Excellent, thanks! I have a box where literally the only thing I care about is CPU speed (build cluster) and nothing on that box is worth anything at all.

There is too much debt in the system. Decades of goosing growth everywhere by making debt easier has put lots of places into tenuous territory where market adjustments combined with sentiment can tank things in unexpected ways.

It had lovely first-class support for batch queues, local and distributed, with load balancing, quotas, forwarding, etc, which you still cannot get on a Linux system. It had great shared/cluster filesystems, that came standard, that ha

I can recommend the Eclipse MAT tool if you want to do this kind of thing locally. A little awkward when you need to do advanced searches through the heap, but generally pretty good.

The telecoms companies are still upset that they lost control of the protocols when IP became ascendant. The last time they tried to take back control was around 2006 when they came out with the ISO stack, a very awkward clone of TCP/I

Without a strong design person at the top to push against this, marketing loves to comes up with these things. For some reason, they really dislike the simplicity of simple numbering. Probably because it doesn't give them any scope to

I routinely run my fairly and complex java UIs clamped to 256M of memory, and startup time is measured in a handful of seconds. Distribution size is not great I'll admit, unless you go to considerable effort to slim the JRE down.
