Is there a reasonable use case for linking to line-numbers on branch/tag on github? If not, it might be good UX to remove that option. i.e. only honour such links to immutable urls. Further, even if you're looking at a mutable ref

Thanks for that, this is really interesting. So - there are ground-based observatories continuously determining the absolute position of the satellites? This seems really hard. The satellites are ~20,000Km up. I think that means a 1 millime

> That should be enough to determine a location. Yes, if you know where the satellites are to the same degree of precision. That's what I was wondering about.

by jbert 12y ago
Does the system rely on knowing the position of the satellites to equivalent accuracy? i.e. "millimetres" accuracy for differential GPS. If so, how is this accuracy achieved? (Obviously the satellites themselves cannot use gps to

Nice. One comment - I think it's not always showing the 'best' options in the initial 3. e.g. 1 - Select Advanced 2 - the two processor options shown are (+11% cost, +13% perf) and (+7% cost, +3%perf). If I expand "more

If you like that, you can put: set editing-mode vi in your ~/.inputrc (instead) and all GNU libreadline using programs will give you vi keys instead of emacs :-)

I'm a little curious why in this case one wouldn't choose to do "RPC over HTTP". Assuming the following points from the post are correct: a) the perf problem is YAML marshalling b) that can be solved via a go rewrite the

Thanks. qdbusviewer shows some available interfaces. Looks like a bunch of konsole stuff never got implemented as dbus interfaces in KDE4. This specific use case seems to be covered by the konsoleprofile command (I wonder why the devs chose

Is there an easy way with KDE4/dbus to get functionality similar to KDE3/dcop? Example task: 1) inspect running konsole task to find exposed interfaces 2) find one related to background colour 3) script up "change background

It's really the code to connect the stages. I want to support 1->many, so a single stage can fan out it's output to multiple consumers. The code which wants to be generic is in the handling of things like setting up channels be

Something I've done in some golang code recently is to fake some OO features. I'd appreciate some commentary on the approach. So I want a few different, but similar things. These are actually stages in a processing pipeline, each

A new language with the same brand has been tried. It's called perl6. I'm also not entirely sure what you intend by "changing everything but keep the name the same". Why not use a new name?

I think you're constructing a strawman and then having a few swipes at it. Perl evolved into it's "new form" some time ago. Modern Perl came out 5 years ago and was really just codifying best practice at the time. It&#x2

Well, it's just that perl for: sub foo($x, $y, $z) ... has up to now been written: sub foo { my ($x, $y, $z) = @_; ... which is annoying boilerplate I agree, but actually pretty regular. [You mean lang

subroutine signatures look pretty interesting to me, albeit experimental. https://metacpan.org/pod/release/RJBS/perl-5.20.0/pod/perlsu... edit: and the copy-on-write string concatenating has the pot

If the two datasets with different access speed requirements are disjoint, you can just run two instances of redis. One for the high-latency gruntwork, one for the low-latency GETs. If the datasets aren't disjoint, then you're t

If you're making your chemical fuel from whatever is in the atmosphere, you're going to have a pollution-neutral cycle (if you can keep a lid on the secondary effects, like unburnt particles).

This is the 2nd part of the "we need lots of clean/carbon free energy" - a way of storing and transporting it. Chemical fuels have a great energy density. Problem is, they dump carbon into the air when you burn them (and also

Would it be possible to add system tests for some/all of these problems? e.g. a test which calls explicit_bzero() in a way which would have it optimised out in a platform with a low-quality port. A reasonably descriptive comment in the

You can try and manage the predictability using msync(), which you'll need anyway if you're doing any kind of transactional write. For more general use, a simple way to keep the amount of 'pending writes' down to reasona
