I learned by doing an 8 hour soldering session, building an open source ECU for an older car. By the end it was easy! Fresh joints in a kit are easier than repair so it’s a better place to start learning temp control etc.

That’s not the pattern I am seeing, but I might be outside the norm. The majority of bot action (scraper, spam) comes from vpn providers by a long shot, ignoring (Chinese ASNs, Indian mobile ISPs etc). I see very little consumer isp action

Not sure what you mean by your first comment - there is no technical reason that I know of that prevents a VPN provider from having their own ASN and address space. As for the latter comment....not sure what your implication is. Yes, bot&#x

the numbers are much smaller than traditional search but they are trending up, and they convert at almost 2x the rate of organic search inbounds. sure you can play catchup later, but the trend is quite clear. if there's one thing the l

I did just this. Using a $2k a year database from a smaller provider that isn't maxmind, claude and I built a pretty slick ASN based categorization system. I can categorize an ASN as a residential IP, a service provider, a legit crawle

See my comment in the parent - there are cheaper options, don't use maxmind!

I just implemented bot and crawler detection as well as ASN based blocking for our website, because I’ve seen a massive rise in scraping coming from VPNs and other networks that mix legit and illegitimate traffic to our service. My theory i

The people I hired in my last round, with over 600 slop and fake applicants, had honest and informal cover letters that stood out. I’m sure I passed up on real decent people as a result, but there’s no perfect way to avoid this right now. I

Anecdata to add to the pile...I pulled three 1u epyc gen2 servers from my production rack 1.5 years ago and replaced them with lower power alternatives for a production storage cluster. I didn't need the extra CPUs for app server stuff

We started building out a set of spam/fraud/bot management tooling. If you have any decent infrastructure in place already, this is a pretty manageable task with a mismash of techniques. ASN based blocking (ip lookup databases can

Doesn’t meet all our product requirements unfortunately. We used returned hexes in certain queries, and we also hacked in directionality of line using least significant 12 bits of the hex (didn’t need that level of hex precision), and we ar

We do something similar for some limited geospatial search using elastic search. We make a set of h3 indexes for each of the hundreds of millions of gps recordings on our service, and store them in elastic search. Geospatial queries become

I do this all the time in a dumb but effective way. Add logging statements to code paths that drop timing info. Another dumb but effective way, instead of using a step through debugger, is drop "here, value is {val}". Telling clau

Flameshot is the best! I've been using it for 10+ years. I have it wired up to some hot keys in my window manager, and have it dump to s3 so I can paste around links to screenshots everywhere for work. https://github.com&#x2

So like texting and driving, but in the air? Flying is hard, I don’t think an automated text based system would be safer than what we have now.

it all depends on your philosophy on dependencies. if you maintain a small set of core dependencies that are there for good reasons and are actively maintained, then rails upgrades are pretty easy. if you have a Gemfile that has a bunch of

Preschool is just daycare with structure, so it costs more. Optional, privately owned. Nice to do 2-3 days a week for young kids to give them more social and learning opportunites. But it’s not public school, it’s usually just a small local

We've been running a production ceph cluster for 11 years now, with only one full scheduled downtime for a major upgrade in all those years, across three different hardware generations. I wouldn't call it easy, but I also wouldn&#

Enterprise server gear is pretty reliable, and you build your infra to be fully redundant. In our setup, no single machine failure will take us offline. I have 13 machines in a rack running a > 10mm ARR business, and haven't had any

I was bit by atop a few years back and swore it off. I would get perfectly periodic 10m hangs on MySQL. Apparently they changed the default runtime options such that it used an expensive metric gathering technique with a 10m cron job that w

Yup, last time I priced this in RDS I got to maybe $20k a month for two reserved instances across AZs. I pay for our rack outright every 3-4 months from what I can tell. Still takes the same number of infra/ops/sre people as well.

Hey fellow k8s+ceph on bare metaler! We only have a 13 machine rack and 350tb of raw storage. No major issues with ceph after 16.x and all nvme storage though.

I think everyone here could be confused, here's my understanding. There were three people in the helicopter that night, two pilots and one crew member. They usually fly with two crew members for a total of 4 people in the helicopter. T
