How else would you say a 3rd party library had a bug under heavy load? 1. You don't want a defamation lawsuit your way. 2. If it was vendor code, you have a contract that may be under a NDA. 3. If it was a vendor, lawyers, lots and lot

Natural gas may be cheap but the cost of the meter and other admin fees cost about as much as the gas.

https://aws.amazon.com/blogs/aws/new-http-3-support-for-amaz... Seems AWS is doing just fine with it. They also have built their own custom chipsets though I don't see a mention of it offloading QUIC to those

The internet itself is not properly tuned and distance is an issue. On a local lan, sure a TCP tuned system will do amazing. On the public internet where who knows where your packet is going it's an optimal but not tuned system with la

Also important servers should also go lower in the rack, but not too low to flood. Learned that from an aircon failure and the top server hit 180F+ and shutdown. Thankfully had temp logs in Grafana to figure that out.

I have some vendor webhooks that spike to above this number for 30 minutes at a time, multiple times a day. They use UUIDs for the event id you are supposed to use for event deduplication.

Plaid does have OAUTH for some banks to make it more reliable. Not a Plaid employee, just a dev completing their OAUTH approval form.

The .NET community started their own version and included some other languages. I think I saw Rust at 1.4s or so but was disqualified because it was optimized to that dataset (no idea how they determined that). Someone wrote some SIMD code

Depends on the contract and the attack size. Sometimes the DC has to pick all it's other customers over trying to handle a DDoS for one. Our DC had an issue where packets over 1492bytes were being dropped in Chicago by one transit prov

It's not a password, it's an API Key. A GUID is 16 bytes represented as 36 characters with hypens but we consider those secure. Even Stripe's private keys are kinda short but their restricted keys are not.

It sounds like this required both local access AND a Active Directory Domain Administrator account (which should have triggered EDR at some point) which is the end game anyway. They just managed to hop out of the AD environment to a non-ad

We host in a datacenter and sending from their IPv4 or our own /24 IPv4 block has no issue. We also have the volume to keep things going as well to build up the reputation.

Database isolation levels is a multi-threaded problem, you have to apply the same semantics to your database as you would your code. If you don't want "phantom reads", then lock the whole table, which is bad. So maybe don&#x2

C# needs them to use them in their own frameworks. GC'd languages has a benefit that Strings can work different then C strings and you get things like interning to reduce memory usage. Now C#(dotnet) took it a step further and put in a

Power steering pumps are electric and have one of the largest wires in my truck. With an EV you also have a heat pump, maybe a heater, coolant pumps now that you don't a constant spinning pulley, windows, lights, headlamps, power doors

Whatever is spent optimizing this to two cores is hours wasted when you could expand. Developer time is still cheaper than Cloud Cores or Ram. Yes you should write SQL queries with basic best practices and have a schema that is just right b

It could be 7A per leg with two power legs so when one trips you are not at 30A on a 15A breaker.

It's why I mentioned our maintenance notifications. I know our DC has lost utility power and not been an issue. Those types of outages you need a plan for at any DC. I'm sure if someone took a dump truck to our DC it would shutdow

Flexential is near us and other major markets. I know our local one just did their monthly UPS battery and generator test. Benefit to Flex is that they have interconnects to their nearby DCs and use Megaport for connecting to Cloud provider

Same. Local company had a NOC and power went out in the area. They had moved into the build a long time ago and had two backup generators at the back end of the parking lot already installed. Power goes out, generator didn't start. 2nd

Our local test those like once a month. Looks like our account manager will get a quick check in after this settles to make sure we won't have this issue.

Yikes, I'm curious how that happened. Our Flexential has 5 generators and a basement full of battery backups along with isolated zones.

Right now google allows the SPF domain, and/or the DKIM signing domain to be different than the From domain, not just a subdomain but an entire different domain. From an ESP perspective, will this drop shared SPF(Return-Path) domains?

You can also look up common cnames or historical DNS records which would always point back to the vendor. For instance, do they use sendgrid, look for a bounce. record that points to sendgrid's servers. Do they use Facebook, well if th

This. If downtime is that big of an issue, you should be on Cloudflare's business/enterprise plan which allows CNAME DNS, have redundant DNS providers with 30s TTLs that flip over to another provider. Better yet if you can 50&#x2F

Gmail doesn't provide the raw FBL (Feedback loop) data. It's only available in Google Postmaster which has an API for domains you have already setup and have to web scrape to set new domains. Validity took over FBL for a lot of pr
