If you do run an NTP server, please make sure it's not vulnerable to DDoS amplification (monlist, readvar, etc need to be disabled) and apply some rate limiting to make it less useful for reflection attacks. And be proactive about moni

I hate it when I can't get in touch with the right engineers at a large company. This (especially the highly targeted ad mentioned on the page) is a very creative way to try to solve that problem. Not associated with Meta, but this piq

BunnyCDN don't run their own network, most of their servers are hosted at DataPacket(.com), but they use some other hosting companies too. DataPacket has a very large network though and is kind of, sort of EU-based. AFAIK most operatio

These days RFC8805[0] is pretty widely supported. But as far as I understand, it's not entirely trusted and geolocation providers will still override that data if it doesn't match traceroutes and whatever other sources they use h

If you're buying transit, you'll have a hard time getting away with less than 10% commit, i.e. you'll have to pay for 10 Gbps of transit to have a 100 Gbps port, which will typically run into 4 digits USD / month. You&#

From having worked on DDoS mitigation, there's pretty much no difference between CGNAT and IPv6. Block or rate limit an IPv4 address and you might block some legitimate traffic if it's a NAT address. Block a single IPv6 address...

This is very challenging, in about one year the biggest recorded DDoS attack has increased from 5 Tbps to almost 30. Almost all of the DDoS mitigation providers have been struggling for a few weeks because they just don't have enough

Over 22 hours of downtime for the one VPS I have in that region. My infrastructure is redundant and spread out among hosting providers and DCs so there's no real impact, but I'm pretty sure this is the longest outage I've eve

> In case you mean the .fw file used in that driver, that's a misnomer. There is no CPU inside the EPDC. That .fw file is a plain voltage waveform file that defines voltage vs time waveforms to get pixels to appropriate graylevels.

NVIDIA seems to have switched to targeting their Tegra series for automotive instead of mobile, where the margins can be higher. For TK1 there's a longer list of devices on Wikipedia. The additional ones are the Jetson TK1 development

> an open implementation of a commercial cpu? At least the x86, x86-64 and ARM ISAs are covered by patents, so you'd need licensing even for an open independent implementation. I imagine this applies to most other commercial ISAs.

Most video players support changing the playback speed. In mplayer it's controlled with the '[' and ']' keys and in VLC it's set in the Playback -> Speed menu.

That's applicable if you compile for 386 or a newer x86 and your compiler generates the code you expect. On AArch32 (ARM) you could use conditional MOV and on AArch64 you could use CSET. I'm sure that other architectures also have
