There's always going to be a case of when using the gif file format is perhaps the best choice for the job. Like all things considered, a limited palette, reasonable canvas size, the use of a transparency bit instead of a channel. You still have a chance to use an animated gif that's smaller than both the webm and webp variants. Because while it still is possible to create a lossless webp file, the codec is completely different and will store data significantly different, and in the certain use cases, can be less effecient

I use GIFs because I want videos that act like images, not videos. GIFs I can copy & paste, and I know that they'll infinitely loop without ever showing a play/pause button.

Yes, videos are smaller, but I'm unfortunately stuck with GIFs until videos work well in Google Slides and iMessage (which also means I'm also stuck with Google Slides presentations always on the verge of crashing...)

I am similar but I would suggest that you could reframe your post. "I started this post with the intention of... and then realised that... (The idea is not a new one/I was wrong/changed my mind because/the idea doesn't make sense etc)." You could even link back to more informative resources on the topic.

Not everything has to be new or novel. You may add to the discussion and enhance it by writing about what informed your change of heart.
I'm really excited to see how this impacts the performance of akka and other stream-like things in the JVM ecosystem. I've spent far too much time tinkering with thread pools and digging through profiles with Unsafe.park everywhere.

Painting in very broad strokes here: If you are coming from C, because you're willing to trade a little bit of speed and footprint to no longer deal with malloc and free. If you're coming from a higher-level, dynamic language, because you're willing to give up some dynamism in order to gain speed and possibly concurrency.

I'd also be curious about this. C10k was a problem at the turn of the century but world has changed a lot since, both in terms of hardware and kernel.

Best reference I could easily find was this experiment that had 100k connections to mysql which has thread per connection model. Seems to handle it well

I live in Alameda County and our new cases have not been dropping for 6+ weeks. Just fluctuating up and down. Yesterday it spiked up a bit though I don't attribute it to Tesla. We haven't really run out of hospital capacity but I wonder where this will lead if the Tesla workers start getting sick. A lot of them also commute in from far off as Modesto for the work.

Clinton did not oppose the repeal at all. He was a cheerleader for the process.

Here's a snippet from his signing speech.

>You heard Senator Gramm characterize this bill as a victory for freedom and free markets. And Congressman LaFalce characterized this bill as a victory for consumer protection. And both of them are right. And I have always believed that one required the other. It is true that the Glass-Steagall law is no longer appropriate for the economy in which we live.

Why shut down jobs if they can be safely done with social distancing? Preventing someone from being to exercise their freedoms and feed their family when they aren't harming others is just illogical panic.
Oh, you mean high school.

In the US, at least, the answer is actually "Yes. You can even develop a passion for a subject and instill it into your students."

My father taught English almost 4 decades in a very rural school. No Child Left Behind had him quite concerned intially.

Until it came down ...

He laughed at it. "Flag poor students early"--okay, his grades were in Excel since he was terrible at math--sort, print, tell administrators to go away. "Need writing samples"--"I have two entire filing cabinets of writing assignments for this years classes. Which drawers do you want?"

Now, I have to avoid generalizing. My father did not teach in an inner city school (the area had brutal poverty--but probably less crime) where they were continuously under threat of being forced closed by the government. He also did not teach in China or South Korea where getting the piece of paper seems even worse than the US.

However, the US isn't as brutal on the "teach to the test" fronts as many other places.
COVID deaths are near 90K in the US (so far).
In many parts of Europe, we have used lockdowns to successfully suppress the virus. 5% mortality of a whole generation is something we cannot accept. Long term health effects are a risk we cannot take. Our societies will at least try to make sure the economic burden is evenly distributed.

We are ending this nonsense, but step by cautious step, and in such a way that people will feel safe outside their homes.

I wrote a long comment, and immediately deleted it because I'm trying to avoid being a confrontational jerk.

I disagree with your assessment of "normal CS jargon". I'm wondering if you mean "normal jargon in the C/C++ community".

In my experience with compiler textbooks and computer science professors who specialize in compilers, compilers are any formal-language-to-formal-language translator. Yes, sometimes sub-types of compilers have specific names, but they are all compilers.

Is there one word for the subject material of the dragon book? I think there is, and I think that word is "compiler". Including source-to-source translators, including assemblers, including preprocessors, including linkers.
What? That's just absurd. I live in a house with tall grass that gets mowed only once, in fall, and there is a absolutely no pest problem. Jest a sea of colorful flowers ans beautiful insects doing their thing minding their own business.

I actually quite enjoy when he’s exuberant, makes it more interesting. Boring leaders are boring.

In this example, Tesla and SpaceX have created at least tens of thousands of jobs in the state (Tesla indicates 50k+ if you include supplier related jobs), and California might be cutting off its nose to spite its face over $600k. That’s a very California thing to do, and if Musk loses his shit over that, it’d be a very Musk thing to do.
One blog post is not enough to warrant a request for money. How do you know they are even telling the truth?
> do whatever it takes to save lives

When did this become the norm? It happened sometime in the last decade, this idea that life is the ultimate metric with which to measure the utility of some action.

I agree that life is precious and up there in importance, but I do not agree that it is the most important variable to optimize for. There are things more precious than life, such as freedom. Specifically, freedom that can be guaranteed for the next generation.

I worry that the "save lives" crusaders will eventually win and everyone will be safely enslaved in a brave new world of a super powerful government that doesn't let you do anything except have sex and do recreational drugs.

The trick with boundaries does not stand true for evasive predicates on unbounded data.

Please note that suggested odd perfect number search algorithm in Python uses an evasive predicate on a big integer which is unbounded.

This means that a typical tracer (or verifier in Turing terms) won't be able to infer the upper bound for the given example.

You: Food producers are essential workers so food production is unaffected.

Me: How do people outside the food industry pay for the food without working?

You: They don’t. The government taxes future productive efforts of other people to buy the food.

Me: But I don’t want the government to take my future dollars and give them away.

You: Too bad chump.

How is outlining the demographic reality an attach? Do you feel attacked when someone points out your eye colour?
I struggle with this too, but then I think on how many of the blogs I read basically say the same thing over and over again, or just rephrase ideas from other places.

When you're familiar with an idea, it seems to you like it's obvious and it's mentioned everywhere, but there are also lots of people out there for whom it will be new. Maybe you aren't the first one to say it, but you're the first one they heard it from. You'll inevitably put your own spin on it, too. I've been working on convincing myself that it's not necessary to come up with some completely novel thought that nobody ever thought before in order to just post something. Practically nobody does that.

Because you matter, and that matters. Take it one day at a time because change is easy once you start so you have to do whatever it takes to just get started on doing something positive. Keeping a streak ends up being a better way to make habits stick — ask Seinfeld.

psql. It's installed everywhere I need to use it, it reads from stdin, and it writes to stdout. It's often the case that I want to take a SQL query that I've developed, generalize it a bit, and use something like

psql OPTIONS <<EOF
SELECT ...
EOF

in a shell script (probably wrapped in a function for convenience).
It's not a real database and doesn't promise ACID though. I think it's fine with the understanding that it's an incremental eventually-consistent materialized view engine that works seamlessly with Kafka, especially if you're already a heavy user.

Otherwise loading data into a real database/data warehouse and using ETL with triggers/views/aggregations is better if you need advanced querying rather than a simple stream to table transforms.
Feigenbaum's constant is a number like Pi or e. It is transcendental. Even though you can't write it down with a finite number of digits, you can write down a formula to compute as many digits as you want (if you are ready to boil the oceans, build a Dyson sphere, harness a Quasar) You can give it a name and refer to it directly.

Any formula like that provides a set of brackets, "real" numbers with a finite number of digits (e.g. names) that we can say that the "phony" number is between. We can make the brackets finer and finer, but you can't pick out one in particular.

Thus 3, pi, pi/e + 6, sqrt(pi-e) are more "real" than the the continuum we imagine between them. Being able to name things, for instance, makes it possible to talk about them.

I started to blog in 2003-4 but these days I rarely write long form. I feel that the the rise of social media and 'micro blogging' platforms have changed reading habits of the masses and people, in general, now prefer to skim through a thread of tweets than reading a long form blog post of 2000+ words.

That's not taking the argument in good faith. Car accidents aren't infectious and furthermore, we don't see 30k deaths in the span of 2 months.

I think Musk could have fared better working with the government to make it feasible to work in the Tesla factories and limit exposure and provide a model for other businesses. Instead he just went ahead and has no guarantee that his employees won't be exposed.
I think Napoleon was more similar to Caesar than to Hitler, and that modern universal sense of disdain towards Hitler is a sign of progress.

Hmm - but what if you want to retrace your steps? Say you're reading child #5 of a very large subthread, you click 'up' to go to the parent, which scrolls to the top of that subthread—and now you change your mind and want to go back to where you were. This seems like what the back button is for.

I'm all for not breaking the back button, believe me, but I fear that people may have very different notions of what that means.
Gossip protocol is useful for propagating node failures or events that are fine with being eventually consistent.

It cannot be used for leader election as these events are time sensitive and needs to be consistent across the cluster within a short duration, that is the reason we have raft & paxos.

A case study in overthinking: CTF writeup
I don't think it stretches anything. The opposite -- that different websites, with interfaces that all vary subtly in a billion different ways, with different traffic sources, with different market positions, with different primary outcome goals -- are able to be compared? I would need to see quite a bit of specific evidence to believe that.

I've worked with brilliant conversion optimizers, in a single vertical niche where we had > 30 websites, each doing between 200K-2M visits/month. We would have loved to test + copy, but every time we ran this experiment, we found huge differences.

One subtle nuance is that "generalizable" needs to be more specific than "this change increased conversions". The true goal of optimization is not the find the B that beats A; it's to find the global optimum.

The Conversion industry tends to similar language as the complementary/alternative medicine space. "I did this thing, it had this outcome. I believe this happened because XYZ. It worked for me, it will work for you!" (People telling stories which may or may not be true.)

That is also why clinical trials for interventions is so important.
