Do you mean following the hash chain to the end of the window?

If you want an exhaustive LZ matchfinder, a trie, binary tree such as LZMA's bt4 or suffix array are more efficient algorithms, especially with window sizes larger than 32KB, and there are other better matchfinders past 64MB such as Rabin Karp for longer matches.

Zip is inefficient as a format on modern out of order CPUs. Modern replacements such as zstd have blocks of literals, lengths and decisions to decode an entropy coded table at once rather than conditionally branch.

Also, beating zip compression is quite easy: use a larger window size and a relatively quick (small number of tested slots) hash chain (or multiple e.g. 3, 4 and 7 bytes) can find better matches.

If decompression time and speed is not an issue, and you aren't limited to LZ based approaches, a bytewise model such as ppm or bitwise such as paq will provide much better compression without too much thinking.

Edit: forgot to mention, the parsing strategy is also important. Finding an
approximately optimal lowest cost path through a block can often save 10%+ ratio with LZ + Huffman.
I use VcXsrv in the multiwindow mode where it uses the Windows 10 window manager for each X app, instead of being fullscreen. Is that also slow on a 4k screen?
While I commend the creator on a good looking and well-designed user interface - I will say that it boggles my mind when people give up their login credentials to unknown entities on the internet.

There is this fundamental disconnect between wanting to save yourself some money - but not realizing that you are setting yourself up for immense risks. You can lose far-far more by signing up to a site like this than what it could ever possibly benefit you.

The same applies to the founder as well - it is all fun to reach 1k MRR - but are you prepared to shoulder the responsibility that comes with managing people's login accounts and finance records? It is a massive risk.

Someone that forgets to set the development flag on their production service should not be in charge of accessing bank accounts.

This is no different than giving out legal or medical advice on the internet. Most people don't understand what they are getting into.

The signal will continue over the seam between two windows, meaning you will cut the wave in the signal "in half". Mathematically, waves are always infinite and to cut them you would actually introduce overtones (higher frequencies) to model the sharp end / start of the base wave. These then result in artifacts regardless of what method is used for the transformation (Fourier or Wavelet).
The only practical takeaway from these suggestions IMO is that "you might still derive great personal benefit from imagining them so covered".

In the real world, there are a few things that could help prevent these outbreaks from bringing the whole of society to a grinding standstill, namely the invention of something that kills targeted viruses directly (thought I read something along those lines a while back). And/or the insight that the way we have constructed modern society is simply conducive to pandemic outbreaks.

The tendency for people to work from home, be schooled from home and getting goods delivered home should not be viewed as a desperate measure, instead it is the way we probably will organize our lives moving forwards, and get a lot of life standard improvements while at it. Not to mention the time and energy we would save by bringing commutes down to a bare minimum.
Some cold weather gear works on that principle. Synthetic string vest for example, keeps you warm even when sweaty. It dries off quickly too when you are no longer sweaty. The main thing is that you are warm and never cold and that you shouldn't worry about soggy undergarment.
When you miss a lot of things in popular culture, you may start to become irrelevant. But I think missing a couple things is OK. I don't want to be the same as everyone else.

You typically hook up changes in your data with static site rebuilds.

Thinking of it as a cache has some merit, but it is more exciting to think of it as a event driven system as a whole, where instead of triggering a render on demand (user wants to look at something) you trigger it when a change happens.

This pattern reduces the need for ad hoc caching and eliminates some accidental complexity as well because it reduces the coupling of management and representation.
I was going to reply with exactly the same sentiment. Born in '79, have never understood the appeal of Twitter or why the news media wants it to be so important.

Everyone needs to do exercise because it has a range of important side effects.

The evidence for exercise as a treatment for mental ill health is not good. It's really hard to disentangle the effect of any form of "activation" (this doesn't have to be exercise, it could be joining a book reading club) from the benefits gained through exercise.

We know it can be difficult for people to start and then maintain an exercise regime, and this failure to stick to it can cause some people to feel bad about the failure.
Oh we love it there. It just happens to be very expensive. Thankfully the favorable exchange rate at the moment helps with other COL expenses (groceries).
The same reason that Quality Assurance or Manual testers as been re-branded as “Quality Engineering / Quality Engineers”. Everyone wants to be an engineer and it’s a recruiting tactic.

Do you see many DBAs anymore? I haven’t seen them for awhile, I’ve seen plenty of Database Engineer or Database Developer job postings.

I’d say if they’re going to call you an engineer, asked to be paid like a software engineer.

So it’s “shortsighted” for a company and it’s investors to worry about profit?

I would say just the opposite, with a very few exceptions, the entire VC startup culture optimized for three outcomes.

- create a product without any profit motive but to get acquired by a larger company. The acquiring company kills off the product and bought the company as an acqui-hire. The original company then posts a message on their blog about “Their Amazing Journey”

- the company gets acquired by a platform company, and the acquirer either kills off the product for competing platforms (see Apple/TestFlight) or tightly integrates it into another product (see Facebook) or let’s a whither and die a slow death (Google/Yahoo)

- it’s a big Ponzi scheme where the initial investors pawn off the company to the public market and the company has little chance of becoming profitable enough (or at all) to warrant its valuation.

Through procrastinating with digg, reddit, and HN over the years, and just being a tech enthusiast before that (reading Industry Standard, Business 2.0 magazines, Web Magazine etc) -

I've been on the leading edge of seeing all the new services come and go.

- started using Google in early 1999 (few months after they launched)

- first 30K users on LinkedIn

- first day user of YouTube

- first 100K users of Twitter

- first 100K users of Instagram

Tracking the evolution using only profanity or racial slurs misses real changes.

There was interesting podcast about some researcher who has been studying the evolution of trolling and 4chan, Breitbart etc. for a very long time. (If someone can find her name it would be nice).

At the beginning it was almost completely edgy middle class teenage boys enjoying using taboo words and writing forbidden comments and irritating and shocking people. Trolling was just for fun. Getting into the news was major win.

Teenage idiocy turned into real world brutality. Doxxing and real world harm. People who are truly racist and have a political agenda joined. Mix of creative trolls and far-right people works because when everything is taken as irony people who are dead serious idiots can't be differentiated from edgy teenagers.
Here's another solution to something else...

Racism is a problem, even in schools, so I don’t think calling it edgy or boomer ranting is help. It minimizes and normalizes it as if it’s somehow acceptable.

Neither the Unabomber or Al Qaeda have any impact on the lives on millions of Americans. Racism that refuses to die certainly does as demonstrated by the number of hate crimes we see in this country both major and minor.

I agree with you on your gripes with COCs, WOKE, etc...

They are political constructs to lock people out instead of integrating people. Individuals that force these COCs on groups of people want a political instrument to gain power over others.

COCs are also used often to try and contain perceived powergrabs.

In your case, with your gripes over multi platform, you have the right to complain about that, I or others have the right to either ignore you or debate you over it, waving a COC is overkill and shows indeed fear of you trying to convince members of that community of your point.

Things like language, unless direct threats of violence, should not be an argument to exclude people from debate.

This is my opinion, b.t.w. I have none whatsoever connection with the community where this issue is happening.

It is however a reason why I hardly join discussions of any kind on most platforms on the internet.

For you the question is: "Do I really want to be around these people?"

One of the things I find interesting is this:

In computer programming, a “solution” to a problem is in essence, a structured framework of thought.

As an example, why are there many different programming languages? Well in addition to various other reasons, for the sake of solving problems in a new or different way of thinking.

Is youth constantly reinventing solutions to already solved problems due to amnesia, or are they perhaps creating new ways to reason about already identified problems?

Just because you saw the problem first doesn’t buy you the right to providing the only solution.

Computer science is unique in that it is art as much as science. Allowing for multiple frameworks of thought on a solution allows for the best solution to rise to the top.

If we are still seeing an influx of new and interesting solutions to existing problems, perhaps our field isn’t as mature as we’d like to think it is.

By the way, computer UIs are still too slow. Fix your web pages / networks.
I like your take on the situation and I like the idea of DevOps being a more formalized version of system administration using infrastructure as code. Unfortunately, what I think it is in most places is middle management playing games with the three legged stool. Application design and development is really quite a different discipline than configuration management and administration. And if you want quality across the board those roles will, for the most part, need to be separated.
Until content publishers go out of business or lock their content behind paywalls, and the "ad free experience" only has hobbyist blogs and amateurs.

A lot of low rent internet chum would also disappear. So maybe that's a fair trade off, but it will also hurt your local newspaper pretty badly.

Nobody has really come up with a good sustainable alternative to ad-funded content for a lot of publishers. Brave is one of many attempts at this, too bad it smells a lot like a crypto currency scam.
Excerpt(s):

"When I reflect on the failures, the root cause inevitably stems from misconceptions around the nature of product-market fit. Founders are blindly searching for growth because they see that as the proof of product-market fit when in fact they should be focused on insight and customer development first as that is more likely where product market fit will be found."

Lyft’s cumulative delight overcame a customer’s investment within the customer’s first ride:

o A rider was first delighted when expecting a long lag time after ordering the car… then realizing it will arrive in only 3 minutes!

o The second delight was fist-bumping the driver — it felt like a friend coming to pick you up.

o The third delight was the interior of the car — it’s not a grungy, smelly cab, but a normal car your friend might own.

o The fourth delight was the ambiance (music, water) and chatting with the friendly driver.

o The fifth delight was the price, much less expensive than a cab ride.

A week into the Lyft launch, one of our associates ran into my office with his eyes wide, shouting, “You have NO idea what you have on your hands. I’ve taken 6 Lyfts this week alone and it’s a GAME CHANGER!”

Delight is seeing your customer’s pupils dilate because they’re so ecstatic about your 10x change."

I feel the same way about Musical.ly/TikTok, but I look at it more as a time/value proposition.

I think the hallmark of being “old” on the internet is embracing the technologies that actually enhance the use of your time and talent and forego or ignore the ones that do not.

I’m sure my 11 year-old daughter disagrees that TikTok is a waste of time and I respect that. But it doesn’t mean I have to understand it. My parents probably felt the same way about BBSes.

I just have to make sure she’s safe and that’s all. She’ll figure out the rest.

one way around this is to develop platforms which apply to a range of diseases. why reinvent some fancy shape of atoms for each disease? it's entirely possible to develop something which works on cancer and coronavirus. just look at CRISPR, or RNAi ... master delivery and you can simply re-target the therapy toward different sequences.

Here (https://github.com/bionicles/coronavirus) is code to design CRISPR-Cas13 CARVER (https://www.sciencedirect.com/science/article/pii/S109727651...) 30mer guides against regions of Coronavirus conserved between SARS, MERS, HKU1, and SARS-nCoV-2 (Covid-19 Virus) and not found in highly expressed Lung protein-coding RNA. Uses BioPython, Redis SADD/SISMEMBER, and tools from EMBL (Emboss Consensus and Clustal Omega Alignment) and data from NCBI. The good news is, it's probably possible to delete Coronavirus genome directly inside the lungs, without vaccines; just deliver nanoparticles or adenovirus (doesn't replicate) with an inhaler and express CRISPR-Cas13 and the gRNA using the Surfactant promoter sequence for lung-only expression of the therapy

disclaimer: I need to work on the readme and write a blog post, but the data is there and the general core works. There's ~30k guides possible and 226 target 13 longest conserved regions across 4 different outbreaks spanning 17 years of virus evolution (provides reasonable confidence these regions are necessary for the virus to function)

If anyone knows some folks in the Pharma / Biotech industry I could use help to run the tests on this, tell em to email bion at bitpharma.com

edit: readme improved. currently looking for promoter consensus sequences for lung (surfactant protein TFs like TTF-1)
Probably a time saver but IMO building a model from scratch is the only way to really understand any business. You can use a tool like this and it will certainly let you “get a handle on it” but I would still recommend the manual method.

For me to understand Instagram stories, it's important to kinda understand the Instagram culture. Normal posts (not stories) are pretty "high-effort" (in terms of shooting and editing) and are posted not so often, maybe every two days at max for your average teen. This left a gap for short-lived stuff (I'm currently eating in this 5* restaurant, I'm currently hiking, I'm on this "cool" party etc.) you wanted to share to a large group of your "friends" (so DM like whatsapp is not a real option because it feels attention-whoring to write it to everyone).

This was mostly filled by Snapchat stories, where you could share exactly that without having to fear to spam people because it's time-limited, everyone does it and it's a very casual format. This feature was basically copied by instagram and is a success for the same reasons, expect nobody uses snapchat stories anymore.

Source: I have young siblings and I kinda use that stuff as well, although not that much.
