It‘s just some ajax logic: Put something in a form, an ajax request will be made an the response is inserted into the dom. The title is pure clickbait, it‘s nothing more than a simple ajax call. The type of logic you‘ve done 10 years ago wi

The problem is there are too many standards and they are all clutered on too many websites. I mean there should be a website listing the standard in an easy way.

And if it is something which is mostly intended to be used in a different system or ecosystem say it. Some time ago one of the big data serialization formats of the apache system was discussed. I didn‘t understand the benefit of it as it lo

Had the same feeling many years ago when i wanted to learn it. Bought the book of some the main creator (?) behind scala and started to read and experiment with on a weekend. But every chapter was filled with many completely different ways

This behaviour is intended in erlang and it‘s very good. You don‘t start to develop the application with wrong concepts. Your ordering from different producers will work on a single machine, but the second you want to upgrade to a distribut

The problem is these repeated single key lookups are random io for the database engine. So the database engine has to predict a threshold for when a scan or random io is cheaper which is very hard to get right, and your io layer changes thi

All database systems could implement many more optimizations. Heck, all these tricks to get the queries to complete faster are only needed because the database engine did not find this fast execution plan. The problem is the more optimizati

You cant protect from a DDoS with a hardware firewall, a DDoS consists of so much bandwidth that your network hardware is not able to simply handle the incoming traffic before any filtering happens. Your expensive hardware firewall can prot

Another problem is you grant access to all repositories. Say you want to use a ci service to build your software, you need to grant them access to _all_ repositories but you only wanted to use them for one project. Github permissions should

I would pay 100$/month if they would solve the slow filesystem performance. Every workaround solution has some problems, most often high latency or simply stopping the sync.

Absolutely the opposite. Fintech and online-only banks have allowed so much new things to differentiate to the old banks. The concept of privacy.com with securing your online credit card purchase, revolut‘s ability to get rid of money excha

That‘s easy if you are just serving static html. But a database replicated on 5 continents? That‘s a lot of latency for replication.

Interested in the same question. So what are the problems of AWS/Azure/GCP Postgresql HA databases. Anyone better than the others? Documented problems for anyone?

You could easily instruct the orm to add a comment in front of the sql query so the database can profiling of a complete http request and show you all the bad things your orm is doing. Something like: /* dbxperience:request=9a7cd2a6 *&

You can just overwrite the cache with new information when the user replaces a file.

I would need just random updates. In almost all cases i wouldn‘t update old records, but sometimes some data needs to be records needs to be rewritten or deleted because of gdpr requests.

cstore_fdw had the same limitations, so even if they say these limitations may not persist forever, i am not very hopeful they really want to solve this problem. But they could solve it with just a little bit of work: * Create a hidden bitm

Because with support for M1 you can prototype your network on your local machine with „good“ performance. There are many cloud solutions etc. but for convenience nothing beats your local machine. You can use an IDE you like etc.

Doing DOM modifications is still much more verbose than using jquery.

Hmm, 'no-cache' meaning please cache it in reality may have been the problem in the past why those damn internet explorers cached ajax responses and the only way to solve it was to append a random query parameter?

And that‘s ok. But it seems no one in management approves benchmarking it now that loading is taking several minutes (!). I am not blaming the developers, they have a lot to do every day. Maybe someone even wanted to try to fix it. But that

I don‘t get the heat of this topic. Yes they wrote some very slow code because it‘s easy to shoot in your foot with scanf. It‘s nothing new that most software could be heavily optimized by just benchmarking slow parts. There is no reason fo

The problem with all these self-hosted PaaS is that they have to reinvent the wheel. Every PaaS needs some database to store information. So what's really missing is that someone would build a self-hosted RDS. A complete solution with

Hashicorp is selling enterprise versions of nomad which are really expensive, the same with consul enterprise and terraform enterprise. They have high pricings so they don‘t need thousands of customers.

The pricing of the Pro Display XR makes it kind of „vaporware“. The difference is it does exist, you can buy it but with this insance pricing almost no one will buy it. The old displays were a thing because they had really been affordable.
