Comment Translation (Score 1) 214

Another advantage of Scratch and similar Free Software projects: they are usually translated, and require minimal language skills. For 8-10 year old kids, it's a great option.

I bought a Tiddlybot/PiBot for my kid, which runs Blockly (https://github.com/google/blockly), and was able to switch the interface language easily (less intimidating).

Comment Junk science (Score 1) 486

Wow. Has anyone heard about buffered writes ? And does kernel-level page cache ring a bell ? No fsync was ever used in the benchmarks, therefore, it is never actually hitting the disk. The only good thing about this paper is that the Java and Python listings are available at the end, for everyone to identify the basic flaws in this research.

So yeah, it's faster to write directly to MEMORY than to do a copy before writing to MEMORY.

Comment I can understand why... (Score 1) 681

Those who did specialize in computer science early on, after high school let's say, tend to not understand physics / chemistry / biology / etc. as well, and it shows.

That doesn't mean they are anti-science / anti-global-warming or anything like that, just that the rest depends more on ambiant politic than critical use of scientific knowledge when shown scientific studies...

Comment Re:Remoting status using Wayland? (Score 1) 189

We've moved from displaying remote applications from the xlib level over ssh, to the toolkit level over ssh (as parent described). It's Unix moving forward, finally.

Microsoft's proprietary RDP protocol or alternatives such as VNC work differently (and usually pretty slow, since they work similarly to xlib, passing compressed bitmap images over the wire). If you want a remote desktop and your network link is fast enough, that's fine, but for most cases, toolkit-over-ssh is more secure and efficient.

Submission + - New LTTng Analyses Tools for Linux

compudj writes: Ever wondered why your program is experiencing spurious latencies ? This blog post about finding the root cause of a web request latency presents a new set of scripts, LTTng Analyses, which allows devops and developers to narrow down the root cause of those latencies, presenting statistics, frequency distribution, logs, and top usage of disk, network, CPU, memory, interrupts, and system calls to the console.
