I would suggest that all requests must require a DNS lookup. No requests directly to IP addresses, full stop. This prevents LAN enumeration from random websites. This is not a big deal for most home networks, but I shudder to think of the

In my experience, SMART doesn't detect anything of value. 95% of my disk failures are: - Seek time gets very high (>80%). - Drive drops dead and won't respond SMART doesn't detect either of these. Setting an alert on seek

If you create the pool with ashift=12, you're fine. The only hazard is if you have an ashift=9 pool (the default, IIRC) and later add a 4096 byte sector drive, you might lose some write perf. It probably doesn't matter for homelab

Perhaps more appropriate would be Hyperscan: https://www.hyperscan.io/ Even though it's now an Intel project targeting CPUs, it grew out of a startup trying run regex matching on parallel hardware.

Sure. Then why not use a DSP? Then you've got lower price, easier programming and can still achieve cycle-accurate timing if you desire.

Right, and this why I believe that FPGAs aren't competitive with GPUs for computationally-bound tasks. FPGAs are weak here because (a) routing costs power, (b) Most ALUs need to be implemented from LUTs, (c) high-order data flow need

Two thoughts: * Most of the algorithms that we want to work with in this domain are doing arithmetic operations on ints and floats. This isn't super difficult to do in an RTL, but it's like implementing C++ objects in assembler. Y

Dell used to do next business day on-site tech visit as standard, and 4-hour for a relatively low surcharge on the purchase price. That was a long time ago though.

Most Macbooks are going to show symptoms before catching fire -- which is thankfully a very rare event. For most people, it's going to manifest as a swollen bottom case. Here's what I look for: - If you put your Macbook on a flat

Like House of Cards, it was intended as fiction but rapidly became difficult to differentiate from reality. See also: Pine Gap

It gets regular media coverage in the US but practically nothing in Australia. I don't understand why this is.

That link shows only a 25% improvement in single-core performance in four generations. That's an embarrassment, Intel. Throwing more cores at a problem has never been difficult. The whole point of the article is that you can buy a many

This. I picked up a Dell T710 with 32 cores and 32GB of DDR3 ECC RAM for $400. I can throw more RAM in it for practically zero cost. It's amazing for batch workloads. For interactive workloads, there's no need to get anything newe

There are plenty of cheap NVMe SSDs that can push 3.5Gbytes/sec (Samsung 970, Adata XPG). Even with dual 10Gbe NICs, you can't match that, nor the low access times of local storage. But I do agree that SAN storage is the norm here

Public key crypto (required for SSL/TLS) is difficult to fit in that RAM footprint. You don't have enough RAM to hold an RSA or DSA key, let alone a certificate chain! Usually devices of that size will use a dedicated crypto chip

High speed, low latency and reconfigurable networking are areas that FPGAs are good at. They're already used widely for HFT.

Right now I'm sitting at: - Slack 1.08GB - Safari (11 tabs) 4.50GB - Chrome (5 tabs) 2.17GB - Outlook 1.13GB These are ludicrous numbers and, frankly, the only reason why I need 16GB+ machines.

I always lifted it up from the heatsink side with my fingers. It overhangs a few mm from the hinge.

I always imagined that the iPad came about because some engineer had a Retina iPhone prototype on a standard 72dpi screen and figured it might work to replace a laptop. Take the old eMac software, and bam, iPad. (100% speculation)

Yeah, it bugged me that they were suggesting it was for secrecy. This is just what prototype hardware looks like. You break out as many electrical connections as possible to enable verification and debug.

It's novel for an LED lamp, though. Most manufacturers just put a heatsink on the back. It's ugly. If you're going for the best possible LED lamp, irrespective of cost, I can't think of a better cooling method.

I got my wife the hair dryer and I'm genuinely impressed with it. It weighs nothing, uses proper PID control for heat and fan, heats up and cools fast and just feels good . The device stays cool while heating the air and it blows a lo

I can't speak for chiropractic as that's out of scope for the FDA and I have no knowledge of the regulatory process there. Homeopathy and supplements are classified as food, not medicine. Therefore, they're not required to se

For a treatment to be granted 'FDA approval', the FDA needs to see evidence of two things: safety and efficacy. Even if a treatment is demonstrated to be safe, if there's no evidence of therapeutic benefit, they won't ap

I think it's a great idea. There's dead space between the menu bar and the icon area. Why not use it for the webcam and shrink that top bezel?

Seconded on the x220. Makes a great Hackintosh with minimal fiddling. Can be upgraded to 16GB RAM for practically nothing and genuine power adaptors are only a few dollars each. More than fast enough to get real work done.

Australians are quite accustomed to bypassing geoblocks and import restrictions, in any case. But that's not really the problem here -- it's more that Australian products and employees may be tainted by unknown government interfer
