No user record in our sample, but mitchs has activity below (stories or comments). Likely we have partial data — the full bulk-load will fill profiles in.

The most fun I've had with strace was debugging a 3-process deadlock. An snmp daemon was blocked waiting for a cli child process to finish, the cli was waiting for a response to a message on a socket it had open with a…
The doubling of J as a means of striding across the array also gives me some concern. While it is cache related, it is cache related for sneaky reasons. J is going to end up, in binary, with a ton of 0s at the end after…
The important part is it safely allows you to pass references or other objects with lifetimes to those threads. (Or at least lets the compiler know so you can avoid having to write unsafe things yourself.) This happened…
The big issue with v6 is you don't know what every ISP is doing with their IP space. The current RIPE recommendation is to delegate somewhere between a /48 to a /56 to every customer. Some ISPs might only delegate a 64,…
Neat. I had made something similar for work a while back, but as a LD_PRELOAD library that intercepted calls to malloc and friends. It would add extra space to every allocation so it could add a pointer at the end that…
I don't like the idea of using caps lock frequently as a modifier. To me a frequently used modifier should either be on a thumb or on the opposite hand. I recently started trying to learn a one handed layout to give my…
I've been a fan of saying that things need to be compliant with RFC 1925 section 2.1. (It Has To Work.)
> "all observable behaviors of your system will be depended on by somebody" Ugh, a former team I was on had that to the extreme. We were customizing open source software for internal use. A lot of operators had (over…
I've always thought of Apollo environments as containers before kernel features for containers existed. With enough environment variables and wrapper scripts taking the name of real binaries to populate stuff like…
It depends on the context. Not every bgp speaker needs the full internet table and frequent route changes. If you use the network to balance traffic across servers, you just need a bgp speaker on a server to inject a…
Eh, I think of the menu of options, taking out Starlink in Europe with a DDOS has a high probability of providing value for Russia and is safer to execute compared with the theoretical attack of getting locations out of…
IMO the motivated state wouldn't go through the trouble to attack sites physically when they could just DDOS spacex's public IPs. It isn't like their IP address blocks are a secret, and it wouldn't be that hard to…
I'm curious, what everyone considers far enough in the future for your code. Eg. are you willing to write code that puts nanoseconds in a 64 but number? That is "only" 584 years after epoch. Would you consider that ok?
Anyone with typescript code that references the non-optional field will get type errors if it is made optional. Though stuffing the string with the v6 subnet wouldn't be the worst thing in the world. Any code that is…
I wonder how long it will take for CDK to support this stuff. I'm not sure how they will back themselves out of the corner of subnets having a required ipv4 CIDR property.
All of this weird behavior is generally inet_aton. https://linux.die.net/man/3/inet_aton
BGP is spoken between networks. There are a lesser known "IGP" protocols stitching together the insides of those networks. IS-IS and OSPF being the most notable. Though the nature of the beast is that when you screw up…
Or just cast the pointer to uint##_t and use be##toh and htobe## from <endian.h>? I think this is making a mountain out of a mole hill. I've spent tons of time doing wire (de)serialization in C for network protocols and…
Refresh, as in transitioning from one image to another on the display. Partial refresh as in not running the waveform on pixels that don't change color, which dramatically reduces the visual noise for the user. The…
From what I've seen working on an e-reader, a big problem for any open source e ink product is the things EIH wants to keep secret about their displays. If you want to use the nice partial refresh waveform, the open…
Heh, a popular consumer electronics product a room mate worked on shipped an update that used example.com as a connectivity test. Apparently they were on pace to rack up $20k/month in server costs. At least their user…
I was initially troubled by the booting of Parler, but I've come around to seeing AWS's position as similar to the payment processors who don't want to deal with porn sites. Doing business with some clients creates…
The real question who is using inet_aton(3). I'm betting none of the online converters.
They need to be capturing src/dest IPs as well as ports for AT&T to have any hope of using that data. Edit to make the comment more useful: If anyone is curious, look up "ECMP hashing." There are probably tons of…
Unfortunately TCP checksums are hot garbage given switch ASIC design. They are a 16 bit one's complement sum over a packet. If you get two bit flips in the same offset % 16, you can pass a checksum. The problem is…
