Dear Dr Bakker
While we don't share concurrent personal convictions on the validity in taking a middle road regarding the use of science or religious teaching to explain the world around us, I have a deep respect for your approach. I am interested to know how it feels to see the works you've produced, which are themselves some of the foundational ideas in your field, get used on either side of the debate to debunk or challenge the strongly held beliefs of the other side? Here I'm referring to some of the conflicts where science observes things that conventional religions simply cannot or will not explain, with each side latching on to their view and discarding the evidence or convictions of the opposing view.
I think the OP's question is valid with one small alteration: Best Storage System for Web Hosting?
Here, I'm using Storage System to refer to a design rather than a product. While filesystems are a good point to look at, I'd be much more interested in the one thing almost all concurrent systems contend over: spindles (or more correctly, drive heads). Partitioning workloads onto separate spindles or SSDs makes a lot more sense than twiddling over the finer points of a filesystem. Serial read/write is well-suited to even slow SATA drives though YMMV, while high-concurrency OLTP DBs benefit from SSD. I can't think of a benchmark that shows any significant performance difference between the headline filesystems when you're not talking about SSD, and if you have the cash to go SSD for all your storage perhaps you should get a professional to advise you better?
I absorb your argument (on the placement of cables), and reject it resoundingly. Large swathes of The Netherlands are 5-50 feet below sea level.
My neighbourhood has been a construction zone for about two years as old apartment blocks are ripped down and shiny new ones erected, all with requisite upgrades to infrastructure necessary to support denser settlements. This involves the use of diggers to create trenches, barriers to prevent seepage and pumps running 24/7 to keep flooding minimised. Water (including central heating or stadsverwarming - municipal hot water), sewage, power, gas and telecoms are all laid down in their respective tracks, covered and never paid attention to.
The only time cables or poles are visible is when their function specifically requires elevation, such as overhead power for trains and trams, traffic signals and street lighting and, of course, purpose-built camera poles.
A very interesting interview explores the approach taken here for water management, and the last photo on page one (although unfortunately low-res) illustrates the effect - not a pole or cable in sight. It's actually quite a shock to visit Miami (I was there in March) and see how blighted the average street is.
One of the core goals of NASA is to discover more about the universe in which we live and how it impacts us. Obviously the search for extraterrestrial life is part of that mission, but if we assume all life (and the planets harbouring them) are identical to our systems then we're going to ignore avenues that might be evident or even more prevalent. What was a patent clerk doing contemplating the nature of space/time?

Well as everyone's been pointing out, yes (near-)daily releases happen now. A packaged release happens every six months, and probably will stay that way, especially for Long-Term Support releases. Sound like Shuttleworth's proposing the whole of Ubuntu's user-base move into the Testing role, and to my mind that's just bad for business. The releases, and especially the LTSs have a defined feature set and take their time to iron out the kinks. With this many packages interacting, I have a tough time seeing how this isn't going to be something of a disaster.
Then again, I've been using Fedora for years, and haven't felt like I've been anything but a beta tester the whole time.
The extension forces requests to be sent over SSL/TLS for all communication, as long as the site supports it. Works on Facebook, even Google searches, so yes this is a useful countermeasure. Of course, it is wholly dependent on the site supporting HTTPS in the first place.
I've tried similar extensions, and Facebook gladly connects over HTTPS when manually instructed to, but reverts to normal HTTP on pretty much any click, this just keeps the connection on HTTPS regardless of the link target. The only downside, specifically on FB but certainly similar problems on other sites: no chat. So there are compromises, but probably worth it.
He's suggesting distributing the CA certificates, not the ones shipping with the appliances. And done right, only one (or if you're conscious, two) CA certs need to go into the distribution/build. Very low overhead. I would even hazard that CRL distribution is not needed if the certs are issued once and all traces (request, key etc) destroyed right away, since then only the Root CA is exposed, and the issued certs are as likely to be compromised as the self-generated ones the appliances have. I know some appliances that won't even let you import private keys, only exporting requests, so even more secure. It gets me down how complex PKI is perceived to be, but then I'm mystified by my car's cruise control...
I'm not suggesting this is a JTAG interface, perhaps my title is misleading. I'm suggesting it's "hidden" in the same way these hardware debug interfaces (both standardised like JTAG or other more obscure interfaces) appear "hidden" to people who don't do hardware/firmware mods. As I mentioned in the first line, I'm surprised everyone's surprised, these are immensely complex parts that sometimes need a root-of-roots, this sounds like just the thing AMD or any other manufacturer would have designed in.
I live in Europe, and have lived in other GSM countries. TA is indeed well written, but omits a crucial part of the story: how networks got their spectrum. Sure, GSM frequencies differ between carriers hindering mobility (in the go-somewhere-else meaning, not the look-I'm-driving-and-still-have-si......-hello? meaning), but I suspect it's because they applied for these differing spectra themselves. Of course you're not going to want to cohabit with your neighbour, it congests your frequencies (fallacious argument, European cities are DENSE) and encourages mobility. Funny that Europe should adopt standards that foster competition while North America is happy to indulge these companies and rip off the consumer just a little more.
I'm actually surprised to find out that everyone's surprised. I've been hacking routers and now work for a telco surrounded by disassembled set-top boxes, and both have serial and JTAG interfaces abundant. Many require soldering, so in that respect it's "hidden" from customers.
Maybe:
- It's often more expensive to engineer these things out of the test systems to ready for production
- and just maybe it's still actually useful especially as you peer deeper into the GHz to get more performance from an existing design.
I'm more mystified by the form factors of these things with every new release - I really miss being able to actually see the PCB on my new hardware. At what point is it going to be more expedient for me to simply place my GPU in its' own little box outside the case to expedite cooling, perhaps a dedicated power supply, of course lots of fans... A Graphics Appliance if you will.

Proposing BitCA then?

Uh, does anyone else have a problem with this thing running on Java? Java causes death

At this form factor, can I squeeze a bunch into my standard HDD form-factor and get some kind of striping going?
