Scary attitude. Lack of ECC in servers has bitten me personally at work to that extent I even use ECC in all of my home desktop computers. Heck, I've been looking for laptops with ECC - unsuccess…

How do you suggest detecting corrupted memory that does not cause the instance to fail entirely, but silently corrupts your data or running processes? Or your page cache: https://blogs.orac…

No ECC ( http://en.wikipedia.org/wiki/ECC_memory ) in that configuration. That's a serious no no for running anything but personal/low importance stuff. Random bit flips …

I use it successfully for a subset of my networking needs (VPN server, VPN client, secondary wifi network, failover 3G/4G routing, security cameras, etc.). Of course the throughput is just 15 Mbp…

It'd be interesting if someone could hack together something like motion, but takes advantage of hardware h.264 encoding. Even if just for still frames.

Memcached/redis sounds like something ARM CPUs might be good at. Maybe execution performance predictability and better isolation of running a single instance on bare metal ARMv8 vs. a hypervisor …

Without taking a stance on what will happen in this particular case -- bubbles burst very slow at first and awfully fast when people panic.

In our experience, same applies to also iPhones, but the offsets tend to be time zone granularity. And a lot of users, especially from Asia, seem to use a U.S. VPN or a proxy of some sort. Their devic…

Seems pretty cool! What kind of latency it achieves?

Wayland is a critical technology for Linux desktop community. X11 has been a reliable workhorse, but its time is up - simply too much cruft accumulated over the years that's not even used anymore…

Not 10 GB/s, but about 1 GB/s (10 Gb/s) thumb drive. Although still almost twice as fast as fastest SATA3 SSD. Some currently available USB 3.0 thumb drives are also pretty fast - up to 150 MB/s write…

It also causes occasional IP-address conflicts. Had this happening before and traced it to an iPhone using an IP-address it did not have a DHCP lease for.

Maybe there's something wrong with your Raspberry Pi, all of mine do over 90 Mbit/s downloads over ethernet without any problems.

Not for consumers, right. But ARMv8 64-bit X-gene should be available: http://www.apm.com/products/x-gene

Currently there's a big problem in GPGPU computing - high latency until the computation results are available. That can be tens of milliseconds. This significantly limits type of tasks you can efficie…

For what it is worth: a) I think decline will start at latest by 2020, probably a year or two earlier. I came to this conclusion by looking at past declines and current regional production data. Expor…

I'd love to see how Go 1.1 compares against modern JITted scripting languages, because I think those will be a major part of Go's current and future competition. Hopefully the benchmarks game will one…

Well, you can still do double-floats, combining two 32-bit floats for a greater precision. While that doesn't get you full double precision, it just might be enough. And of course you can extend the s…

It's not inconsistent at all. In Lua, only nil and false are not true. Everything else is true, including all integer values, strings "0", "false", "", etc. I'd rather say Lua is one of the most cons…

You don't need a full IP stack in order to do something useful. 32 kB flash and 4 kB RAM is more than enough for basic IP-networking. http://www.rowley.co.uk/msp430/uip.htm - requires less than 2 kB…

I think it should use ECC memory and an i3-CPU that supports it. Random memory bit flips in are going to corrupt data at a steady pace. Intel i3 processors that support ECC: http://ark.intel.com/sear…

Hopefully they have more products too, just in case current trajectory crashes into some obstacle destabilizing it.

The article didn't mention TLS-session caching. Sometimes keep-alive alone is not enough. Enabling session caching helped us to reduce nginx server CPU load by about 90%. Add this in nginx.conf "http"…

Javascript is overall cleaner than Obj-C. Both languages can of course be used and abused in many ways. Javascript is going to require less code in general. On the flipside, larger projects are harder…

No, that's just a normal 5 bitplane display mode with a copper trick. Real original 6 bpl HAM didn't need copper, it depended on current beam position left side pixel. For each pixel right side you co…

"Nobody actually needs 4G yet, we just like it in our fancy things." Nobody who doesn't need 15 ms latency (low jitter [low latency stddev]) vs HSDPA 90 ms+ (huge jitter, latency up to 1000 ms+). LTE …
