There is no requirement in the Java language to use getters and setters.

Or when IBM renamed everything Websphere.

I have not had much experience with DB2, but given that the relational data model and normalization was invented at IBM (Codd) and IBM's implemenation of those concepts was DB2, DB2 performing poorly with a normalized data model seems strange.

My recollection was that DB2 did not support multi version concurrency control like Oracle and Postgres did. The result was a lot of lock contention with DB2 if you were not careful. MVCC was eventually added to DB2, but by then it was too late.

Maybe it’s because you are really a computer programmer. Computer programmer employment is expected to decline by 6%.

My initial reation was 'What is a CMS'? Naming your company or an initialism and never saying anywhere in the product description what the initials mean is not welcoming. Now I know that anyone who does not know that a CMS is a 'Content Management System' is probably not a likely customer, but you never know, and expanding the initials somewhere shold probably be possible.

You don't have to tip an Uber or Lyft driver either.

I think more effort should have been made to live with 65,536 characters. My understanding is that codepoints beyond 65,536 are only used for languages that are no longer in use, and emojis. I think that adding emojis to unicode is going to be seen a big mistake. We already have enough network bandwith to just send raster graphics for images in most cases. Cluttering the unicode codespace with emojis is pointless.

This article is nearly 15 years old (2013). According to center on budget and policy priorities, the number of SSDI beneficiaries has fallen from is peak in 2014. So this article was written about a trend that peaked a year after its publication and had reversed over the past 15 years. Odd that it would be reposted today.

Why would anyone buy their game engine when it is available for free? Seems like a solution for a problem that doesn't/won't exist.

Can a systems programming lanugage use garbage collection? I don't think so.

Seems to me that if Congress would prefer that any disputes arising from the implementation of their laws be handled by the admistrative agency charged with enforcing it, all they need to do is say so in the law. Not sure how the courts could get around that.

I found 'A Philosophy of Software Design' by John Ousterhout to be useful. It contains alot of solid easy to understand advice with many examples.

I think whats more harmful than unit tests are code coverage metrics for unit tests that devs feel compelled or are required to achieve. The easiest way to achieve code coverage goals for tests is to write lots of small tests that test individual methods, but test very little of the interaction between them.

I feel that the goal of unit testing should be to test the largest unit possible without requiring external dependencies. In the language of domain driven design, this means to test the domain model. If you can get extensive coverage of the domain model as a whole, system tests can be used to test the complete system.

Alas, I have seen very few software systems with high quality domain models. It is not an easy thing to achieve.

You need to spend $16,666 just to cover the $500 annual fee. That’s a lot for many people especially when many low end retailers don’t accept AmEx. As already state rewards cards are a subsidy for the rich, or at least for people who spend a lot.

They can but they generally won’t. Use of the chip on the card shifts fraud liability from merchant to issuer. Burner card numbers are for card not present transactions.

NY state has plenty of room for onshore wind, just not in the places where most of the people are.

Is it really that much different? You still need to handle a Left value, and a lot like handling an exception.

That’s not true. Java has 2 types of exceptions checked and unchecked. Checked exceptions are what this thread has been calling errors, and unchecked exceptions are what this thread has been calling exceptions. Maybe it was a mistake to call them both exceptions, but Java also has 2 types of errors.

Here is an example. Go let’s structs be passed by value or by reference. The programmer needs to decide, and that adds complexity that is largely irrelevant for modeling complex business logic. Java does not provide a choice, which keeps it simple.

Not sure what you mean by "the database holds locks for the minimum time needed." Locks are always held until the transaction commits.

In the Lost Updates section, a more straight forward solution is to use the FOR UPDATE clause in the first select statement. This locks the record and prevents concurrent updates.

Is this really a Google OAuth issue, or more failure my many service providers to properly verify the OAuth token assertions before allowing access? Seems to me the latter.

I found a chestnut tree of moderate size on my property this year, and for time thought it might be an American Chestnut. Alas I eventually concluded that it was a Chineese Chesnut. Still a nice tree, but hardly as exciting.

Not at the scale involved here.

This seems to me like an example of how difficult it is to organize a company around a goal other then making money. As a non-profit, OpanAI was not supposed to be a profit maximizing enterprise. But how is a board supposed to opperate, and set objectives without a clear goal like profit maximization? Usually a boards represents the owners of the business and their interested. The OpenAI board does not represent the owners because there are no owners. So the board is just 6 people and their opionions. Hard to see how that can work.

How about using Kafka for the WAL? Anybody tried that?

Another sign that the gold rush phase of the web is over. It is no longer enough for companies to just increase their active user base and be rewarded with a rising share price. Google gets paid for showing users adds, so if users aren’t looking at the adds, there is no reason to incur the cost of showing them content, and if they stop using the service, so be it.

It’s been 25 years, but it’s nice to see that fundamental economic principles still hold even on the internet. I expect that we will be seeing much more of this in the near future.

To avoid deadlock, you need to ensure that locking happens in the same order in all concurrent transactions. So account A must be locked before account B and never in the opposite order. So if account B is the account being debited and therefore the account that needs to have a sufficient balance, then account A must be locked first. If account A is the account to be debited, then explicitly locking account B is not necessary. It will be locked when its updated.

I would not call it a problem with capitalism, I would call it capitalism's greatests feature. A free enterprise system ensures that resources are used to create the greatest value for consumers. If firms did not need to seek a profit, why would you expect to get anything from them that you value.

Customer friction at checkout. The more difficult a merchant makes the checkout process the more likely customers are to abandon the checkout. Some of those abandoned checkouts are fraudsters, but other are legitimate customers who don't want to deal with the hassle. It is up to the merchant to decide how to weigh fraud against lost sales.
