psycopg2 is a Postgres driver, it is not a query builder like jOOQ. Python's equivalent would be SQLAlchemy Core.

Quite a few times I've heard the line that blockchain can revolutionize supply chains, but I still don't understand it. Since you're dealing with physical goods, you're relying on the participants of the system to enter

dogpile.cache [1] implements this pattern (or at least a very similar pattern) for both memcache and redis using locks. If the cache value doesn't exist, attempt to acquire the lock and generate the value. If the lock can't be a

$0.00099 per GB in Virginia and Oregon. That's a quarter of the cost of glacier! I'm curious how they're able to achieve that. They released to all regions at once (including GovCloud!), so that suggests its not new hardwar

Source to that? My napkin math tells me speed of light across US is ~10ms, my experience tells me latency is ~100ms (certainly not 1s), so that's only one of of magnitude.

I think jQuery is still a relevant tool for building dynamic websites—animations, carousels, pop-ins, etc. However, for building SPAs, jQuery has been eclipsed by Angular and React. And thank god for that, jQuery was always an ill-suited to

S3 replicates across available zones, meaning copies in multiple DCs but in the same general area. You can setup a bucket to replicate a bucket in another region, at double the storage costs plus bandwidth charges.

Last I checked, the backup service exclusively used the Sacramento DC. Has this changed? Being in the Sacramento area myself, I'd be much more comfortable if my offsite backup was more than a couple miles away.

Given my experiences with Stackpath's CDN, I wouldn't trust them with any sort of workload. They bill themselves as the "secure" CDN, yet were not validating SSL certs on the origin.

Notably new is the assignment expressions [1]. This was quite controversial and the battle around it caused Guido to step down as BDFL [2]. I personally think it's quite a nifty feature. I often end up writing something along the lin

They don't mention it in the article, but TLS comes at an additional cost. Same price per hour and per LCU, but an LCU gets you less with TLS. Standard LCU: - 800 new non-TLS connections or flows per second. - 100,000 active non-TLS

AFAICT, this actually isn't running SQL against data in DynamoDB. Rather, it syncs the the data in DynamoDB with their [Rockset's] own proprietary database, and runs SQL against that data. It's effectively the same but techni

Certainly everything should be done to reduce the number of incidents, but you can't eliminate the need for on call.

One thing I've been wondering about is how smaller organizations handle on call. Looking at the roles laid out [1] and assuming an on-call schedule of 4 weeks off, 1 week secondary, and 1 week primary, that's a team of at least 2

Since the flexbox inspector is is a sidebar in the DevTools, they're working with similar size constraints as a mobile device. I think taking design inspiration from mobile makes sense.

Why is it so expensive? Not only is the entry point $200/m, the instances are twice the price of their EC2 equivalents. (At first I thought perhaps the price included multi-AZ, but it doesn't.)

Looks to be 1000 minutes, same as when I was on the platform. If your builds only take a couple minutes that goes a long way.

Glad to see this, Fargate was a pretty steep premium. Comparing an on-demand m5.large to the equivalent Fargate container looks to be a 20% premium, which seems reasonable. Next I'd like to see an equivalent to EC2's reserved ins

Preflights are cached, but because CORS is per-URL caching can be of limited value. If your API uses `/info` and `/edit`, a preflight request has to be made for both (assuming a preflight is necessary). If your application has d

I was speaking of SQL, but if you can write it in SQL you can usually map it to SQLAlchemy. If worse comes to worse, you can use text() to drop down to raw SQL for just a portion of the query. SQLAlchemy’s Postgres JSONB type allows subscri
