I can see it now: “New worm infects PDFs, causes users viewing them to mine Bitcoin.”

It looks like the Hulu subreddit is full of unhappy people complaining about it.

Doesn’t appear to be a Hulu Threadiverse community.

After this removed support of two libraries from curl, there is still support for ten different TLS libraries.

That’s bonkers. I didn’t even know that curl supported more than OpenSSL and GnuTLS.

I think that Tetris is probably the oldest game that I’ll play some implementation of occasionally. I don’t know if I’d call it my favorite, but it’s aged very gracefully over the decades.

Musk lost a lot of money on his last social media company purchase, Twitter, after spending some time in court trying to abort the purchase. I’m not at all sure that he wants to buy another social media company.

It’s something in the charging circuitry. It works fine when it’s on wall power, but it just does not charge the battery.

And it’s not the battery itself because I’ve tried getting new batteries for it. It’s something in the charging circuitry. It works fine when it’s on wall power, but it just does not charge the battery.

At least some Dell laptops authenticate to the charger so that only “authentic Dell chargers” can charge the battery, though they’ll run off third-party chargers without charging the battery.

Unfortunately, it’s a common problem – and I’ve seen this myself – for the authentication pin on an “authentic Dell charger” to become slightly bent or something, at which it will no longer authenticate and the laptop will refuse to charge the battery.

I bet the charger on yours is a barrel charger with that pin down the middle.

Yeah, looks like it.

I don’t have a great picture for the 65W one, but the 45W charger here has an image looking down the charger barrel showing that internal pin.

If you want to keep using that laptop and want to use the battery, I’d try swapping out the charger. If you don’t have an official Dell charger, make sure that the one you get is one of those (unless some “universal charger” has managed to break their authentication scheme in the intervening years; I haven’t been following things).

EDIT: Even one of the top reviews on that Amazon page mentions it:

I have a DELL, that has the straight barrel plug with the pin in it. THEY REALLY made a BAD DECISION when they made these DELL laptops with that type of plug instead of making it with a dog leg style plug. I have to replace my charger cord A LOT because the pin gets bent inside and it stops charging at that plug, but the rest of the charger is still good…

Up until the early 2000s, serial computation speed doubled about every 18 months. That meant that virtually all software just ran twice as quickly every 18 months of CPU advances. And since taking advantage of that was trivial, new software releases did, traded CPU cycles for shorter development time or more functionality, demanded current hardware to run at a reasonable clip.

In that environment, it was quite important to upgrade the CPU.

But that hasn’t been happening for about twenty years now. Serial computation speed still increases, but not nearly as quickly any more.

This is about ten years old now:

Throughout the 80’s and 90’s, CPUs were able to run virtually any kind of software twice as fast every 18-20 months. The rate of change was incredible. Your 486SX-16 was almost obsolete by the time you got it through the door. But eventually, at some point in the mid-2000’s, progress slowed down considerably for single-threaded software – which was most software.

Perhaps the turning point came in May 2004, when Intel canceled its latest single-core development effort to focus on multicore designs. Later that year, Herb Sutter wrote his now-famous article, The Free Lunch Is Over. Not all software will run remarkably faster year-over-year anymore, he warned us. Concurrent software would continue its meteoric rise, but single-threaded software was about to get left in the dust.

If you’re willing to trust this line, it seems that in the eight years since January 2004, mainstream performance has increased by a factor of about 4.6x, which works out to 21% per year. Compare that to the 28x increase between 1996 and 2004! Things have really slowed down.

We can also look at about the twelve years since then, which is even slower:

https://www.cpubenchmark.net/compare/2026vs6296/Intel-i7-4960X-vs-Intel-Ultra-9-285K

This is using a benchmark to compare the single-threaded performance of the i7 4960X (Intel’s high-end processor back at the start of 2013) to that of the Intel Ultra 9 285K, the current one. In those ~12 years, the latest processor has managed to get single-threaded performance about (5068/2070)=~2.448 times the 12-year-old processor. That’s (5068/2070)^(1/12)=1.07747, about a 7.7% performance improvement per year. The age of a processor doesn’t matter nearly as much in that environment.

We still have had significant parallel computation increases. GPUs in particular have gotten considerably more powerful. But unlike with serial compute, parallel compute isn’t a “free” performance improvement – software needs to be rewritten to take advantage of that, it’s often hard to parallelize solving problems, and some problems cannot be solved in parallel.

Honestly, I’d say that the most-noticeable shift is away from rotational drives to SSDs – there are tasks for which SSDs can greatly outperform rotational drives.
