Ask HN: Why do Android phones become slower?
I have been using my phone for about 3 years. It has become slower and slower. In the beginning, everything opens instantly. Now, it literally takes 10 seconds just to open Chrome. I quit all the applications after I am done with them. In that case, I don't understand. What is making my phone less responsive?

(I tried to lookup, but all I got are some weird claims from some shady news websites about battery dying or system updates, which does not really make sense to me.)
Yes though the point is the same, Enumerable gives the objects methods (internal iteration), in Python you would use built-ins max or filter or a list comprehension on an iterator (external iteration).
I would be surprised they pay people when so many people are willing to talk about Notion for free. So yeah they started hiring Notion ambassadors (and paying them) recently, but much of the growth they had was without paying.

I think they never paid for an ad, they only have a handful of people working in marketing, about 5 according to Linkedin.

The reality is people who love Notion want to shout it everywhere and as a result you see content about Notion everywhere
I'm using it (in a browser tab) and I still find it very slow. This is the reason that I don't enjoy using it and have not expanded my use of it.
It's almost as if the governments of the world had no power to actually stop this and they just utilized it as a major power grab.
The best part is we’re not even through the Covid situation yet people are calling out winners and losers by looking at Covid deaths only.

Let’s revisit this in a decade when folks can add up deaths from Covid (and delayed care for other issues), mental health and economic impact.

THAT will be interesting to see.
I agree. Also, I believe that stautory leave in Austria is like 40 days, compared to 28 in UK.

UK has some tax free investments, but wouldn't boost net income.
I would counter that by saying Daphne Oram was the GOD mother of everything, and paved the way for Delia and women in general by actually starting the BBC Radiophonic Studio.
I can understand your point a bit more about wondering about one-time fee versus subscription as you were operating under the assumptions of recurring server costs.

I was aware they were using Chrome.Sync and that it did not impose a cost so that changed things in my head.
While I agree comparing countries can be apples and oranges, it makes sense to compare the Scandinavian countries. That Norway and Finland were much lower strongly suggests Sweden's strategies worsened things.

Article graphing the UK data showing negative efficacy against disease in the raw data, and
discussing the semi-public fighting that's broken out between arms of the civil service over how to disguise or de-emphasise the results:

https://eugyppius.substack.com/p/ukhsa-efficacy-stats-death-...

Norway finds no effectiveness against death (but oddly, some against ICU admittance)

https://dailysceptic.org/2021/11/14/norway-study-finds-zero-...

Essay discussing how although raw UK data shows negative efficacy, it gets adjusted using a test negative case control design to show high efficacy. This contradicts data not only from Norway but also Sweden and Qatar, so is there a flaw in their approach:

https://dailysceptic.org/2021/11/12/why-are-the-ukhsas-estim...

Another essay showing that the TNCC design requires absence of "viral interference" which may not be the case here:

Daily Sceptic has been doing a lot of reporting and analysis on the UK data (it's a UK site), usually with very high quality of analysis. A lot of it comes from PhDs and data scientists of various kinds.
Are you sure on the economics part of the equation? My impression was that Sweden also had a bigger GDP per capita decline than the other Scandinavian countries. I don't have the data in front of me, though.
The point of lockdowns v1 was panick and healthcare supply chain related. Once we knew who was dying from this (May-2021) we should have stopped given the millions who will suffer and people who will probably die from tanking the economies of the developed world. But hey, have to stick the agenda of report9 to the WHO which predicted 200Million+ dead in year1...
Yeah, I buy a lot of toys for my kids, but they're more interested in used boxes or plastic bowls than actual toys. A baby is much more likely to use a pair of keys as a teether than actual teethers.

But a ball is universal. You can throw it, kick it, roll it, chase it, hit it with a stick. The kids will fight over the ball. You put it in a parking lot or an empty field and they'll find something to do with it.

You can put a can on the ground and throw/kick the ball and see who hits it. It needs a surprising amount of skill. And when that gets too easy, you can have someone whose role is to block the ball from hitting the can.
Oklahoma and North Dakota. Various other states have restricted non-competes recently, particularly for low wage workers https://faircompetitionlaw.com/wp-content/uploads/2021/06/No... and more are working on it https://faircompetitionlaw.com/changing-landscape-of-trade-s...

I'd emphasize "one reason" and de-emphasize "always" :)

The site linked above likes to throw cold water on the idea that non-competes are bad for workers, startups, etc (e.g., ND and OK aren't famous for their tech industries), see blog posts at https://faircompetitionlaw.com/ ... my bias is the other way (particularly enjoying https://ssrn.com/abstract=2517604), but the evidence is complex. Fortunately the aforementioned changes should generate new evidence.
This just adds another layer to the system? I'm not really following what the advantages are.

More detail on the Kormendy controversy:

1. Archive copy of withdrawn paper: https://web.archive.org/web/20211028230225/https:/arxiv.org/...

2. Coverage at Retraction Watch: https://retractionwatch.com/2021/11/03/astronomer-apologizes...

"The book required 5 years of intense, essentially full-time work. I believe in it. But for now, all advice to me has been that it is dangerous and unwarranted even to defend the work. I therefore am unable to comment further on events. I am sorry — more than words can say." -- Kormendy

3. Kormendy's Apology: https://chandra.as.utexas.edu/apology.html

"I apologize most humbly and sincerely for the stress that I have caused with the PNAS preprint, the PNAS paper, and my book on using metrics of research impact to help to inform decisions on career advancement. My goal was entirely supportive. I wanted to promote fairness and concreteness in judgments that now are based uncomfortably on personal opinion. I wanted to contribute to a climate that favors good science and good citizenship. My work was intended to be helpful, not harmful. It was intended to decrease bias and to improve fairness. It was hoped to favor inclusivity. It was especially intended to help us all to do the best science that we can.

A specific aim was to provide calibration of the "black box" of jump-starting successful research careers. One of my aims throughout was to help young people as they start their careers and to help established scientists as they make decisions on how to lead the scientific enterprise at their institutions and beyond.

But intentions do not, in the end, matter. What matters is what my actions achieve. And I now see that my work has hurt people. I apologize to you all for the stress and the pain that I have caused. Nothing could be further from my hopes.

The PNAS paper and arXiv preprint have been withdrawn as thoroughly as the publication system allows. The arXiv withdrawal is accepted by arXiv and appears in the posting for Wednesday, Nov. 3, 2021.

The same may be the fate of the book. I hoped to generate healthy discussion and to provide practical aids. We will see in the coming few months whether any good can be salvaged from its development. Meanwhile, publication of the book is "on hold".

I fully support all efforts to promote fairness, inclusivity, and a nurturing environment for all. Only in such an environment can people and creativity thrive."

I also have a hard time understanding abstract things without clear examples. I think that's the difficulty you're having?

This SO question has many answers that are a bit more concrete with the examples: https://stackoverflow.com/questions/3784389/difference-betwe...
I think engineers tend to have a borderline-compulsive need to understand why the simple/obvious solution didn’t work. Sure sometimes the comments are along the lines “duh, just do X” but I think they’re usually “why not do X?” asked earnestly. It’s hard to tell on the internet but I think most engineers ask questions like that not to second-guess decisions but to get a better understanding of complicated systems.
What a shame, this lowers my view of Id, someone with money should step in and countersue or whatever you do in such cases..
And 20 minutes into the future, when Google is the undisputed monopolist of web browsers? Do you trust Google to be our unimpeachable lord and master?
Maybe better to compare to Singapore which had ~6 deaths per million earlier this year, has one of the highest vaccination rates in the world but since barely relaxing their restrictions now has ~120 deaths per million, raging number of cases (mostly vaccinated) and had the highest level of suicides last year since 2012?
> "But intentions, in the end, do not matter."

Nonsense. I'm getting a little alarmed by the pro forma recitation of this doctrine.
> Also yes, overdraft fees are truly disgusting. What's worse is that there are transactions that can bypass "overdraft protection".

Totally agree. I used to work in the lending team at a UK bank. Someone on my team was on a panel discussion about change in banking, and gave a brilliantly frank answer on that point: https://youtu.be/M3toHjAABvw?t=3511

> it's an...I was gonna say "unfortunately rare" but I think I'll go with "severely under-represented" point of view in this industry

I do remember being disturbed by this. I'm from a totally privileged background myself, probably quite a bit more than the rest of us were, but still, something about watching that 'total amount lent' line increasing, it just never sat right. It felt ... profane, like a funeral director cheering because there were more car crashes this quarter. It's hard not to mentally flip that profit graph upside down.

And I'm glad that our industry is working harder to be diverse in gender and ethnicity and sexual orientation &c, but it feels like diversity in social class is still horribly neglected. It makes such a hugely palpable difference to have even one person in your team whose parents might be among the people you're lending to (or whatever it is that your company does).

I honestly don't well enough understand the sociology of software engineering to fathom why we're so silent on that particular dimension of privilege.
"The whole spectrum" for GPS FHSS being a relatively tiny frequency range. So still trivial to jam.

There are physical restrictions on transmitter aerials which make really wide FHSS impossibly difficult. Especially from a satellite. So GPS still transmits on the same standard 5 frequencies, with some special codings.

The antijamming features work a little differently. If you know a random code sequence you can use various digital noise reduction techniques to improve the SNR and help punch a signal through noise.

But if you blanket blast the transmitter frequencies and their associated components with noise, you're still going to have an effective jammer. It will just have a smaller effective range.

Automation is great when there is a labor shortage. In this case just give people money. Maybe you won't get houses built in 24 hours, but you also won't be air dropping boring, repetitive, experimental architecture on a community.
Ask HN: People of Comp-Sci and related who love their job. What do you do?
Dear people of computer science (and related fields) who love their job. I'd appreciate if you can share your experience regarding the following:

How do you define your role?

What do you love about the work you do?

What part of your work are you surprised you love today?

Which part of work affects your passion?
Things which are part of your responsibilities and/or things which are enabled by certain properties of your work place?

What would you advise your past self towards the end of your studies and before/at the beginning of your career?

Which role do you find interesting today and haven't heard about during your studies?
So... and I mean this genuinely: nothing in that word salad refutes the fact that the vaccinated are 20x less likely to die from covid.

There are always things for you to be upset about. But facts are facts. My "side" (led, perhaps, by misinformation pushed to us by various Institutions acting in The States Interest) was right, yours (seeing clearly) was... wrong.

So maybe it's time to maybe revisit some of your other priors?
Ah yeah, I've recently received for free an iMac running Macos 10.9. It's simply impossible to upgrade; the only proposed upgrade release is 10.11, the installation starts then fails in a loop. Fortunately I don't actually need to save anything from this machine, and I have another Mac to download a newer OS installer, but that's quite painful.

Focusing on the data and getting everything into 1 happy schema can eliminate problems you didn't even know you were allowed to disregard.

Success with these efforts is unlikely in larger teams. You need to put the most wizened chef in your data modeling kitchen and have them serve the business stakeholders until they are leaving 5/5 reviews on yelp. Design of schemas by committee is how you wind up with N of them and up to N^2 bullshit protocol/mapping/service layers for communicating between them.

You can iterate this problem space with Microsoft Excel. You do not need to write any code to figure out the most difficult part of most software products.
Ask HN: Looking for a book on algorithms and data structures
I want to learn Algorithms & Data Structures from scratch then move on to doing LeetCode.

But I want a structured guide / textbook that I can follow which also contains exercises.

I have checked the CLRS book, but, it's more of a reference than a book that you can read from cover to cover. For example a basic Stack is explained in a page and a half or two, for me this is not enough, I want a book that can go into the details of each specific DS or Algorirhm.

*TL;DR:* Are there any books better than CLRS for DS & Algos?
It's also possible to correlate the shape of the social graph across services to deanonymize users across social networks.

So I don't think not proving ownership of multiple identities buys much for anonymity. For deanonimization just a reasonable probability is sufficient. But a proof adds more utility to the person proving their identity. You can still have hidden throwaway accounts when needed.
I'd personally put the threshold for "complicated" at "do you need a keyboard to be able to use it". So it's pretty complicated.
It goes all the way back to Middle English, with roots further back. https://www.etymonline.com/word/doom

“Modern adverse sense of "fate, ruin, destruction" begins early 14c. and is general after c. 1600”
4chan hardly had any responsibility for Qanon. Q poster was banned very early after most recognised it as a larp. It is overwhelmingly the legacy of infinity chan.

This is not withstanding who was eventually revealed to be one of the people behind it all, but I hate to overexplain this because the bottom-line is that this whole idea that lowtax was some kind of Gavrilo Princep is over-the-top and kinda dumb. The 4chan-qanon connection is tenuous, only more tenuous than the idea that a "hentai ban" caused 4chan, which only happened much later after 4chan was founded.
I think this is a dialect difference. To me (and presumably the parent?) private bank means a bank that offers private banking services to wealthy clients which generally involves selling certain loans or investment products rather than a current account. Whereas I think the grandparent meant “bank not owned by the state”. But I’m not entirely sure
Hard pass. I'll stick with Domain Driven Design, though for simple systems, old school monoliths are fine. Complex enterprise systems end up being a cluster-F when driven into a monolithic state or when the primary architectural foundation is some database.

Of course any traditional relational DBA would love this article. But relational databases are an architectural anti-pattern.

Don't start with the data.

Start with the domains.
It's incredible. I was dependent on prescription stimulants to be functional and I managed to give those up. But 4chan? I've tried 4 times and made it to a month, max.
Doom is an extremely old word[1] that was originally neutral in meaning, but has had a negative connotation since the 14th century.

I fished snapper all my life in the Gulf as well thinking it was unique to the Gulf. I was delighted to find red snapper in Indonesia during a visit there. The genus Lutjanus is a fairly well distributed in the Atlantic, Indian, and Pacific Ocean and they are all tasty.

The beachside Indonesian practice is to cook them in smoke houses with coconut husks as fuel.

Anyway, snapper is everywhere, and everywhere over-fished.
I started down this path years ago because bookmarks and sites I know used to exist started vanishing faster than I could catch up with my to-read folder.

Link rot is real and sites/information I used to be able to find on google in seconds have been gone for years.
The word doom was around long before the game.

This is ridiculous. Companies don't magically own all the words.
This article is a high level overview of the situation and doesn't get into some of the lower level technical issues with HFT firms. Just as one example: ISO (intermarket sweep orders) are routed from brokers to the different exchange venues. HFT firms have optimized their latency to the point they can actually see an ISO order on exchangeA and quickly cancel their orders on exchangeB, exchangeC before the customers order routes to the other exchanges from the broker. This effectively amounts to phantom liquidity since the size vanishes before the trade can fully execute across all venues. There are many technical games like this that are played, and its cat and mouse game with HFT and the SEC. It would serve investors well to have a single regulated exchange where all the liquidity is concentrated. The simple idea that market makers are valuable because they provide liquidity ignores the fact they play numerous technical games which are harmful to retail investors.
Oh data breakpoints! Our savior. In the bad old days Intel had a big 'blue box' that ran ISIS and had a $1200 cable and circuit board called 'ICE' for 'In-Circuit Emulator'. It could monitor the bus and trap on certain memory operations. My brother worked on that right out of college. He met his wife over that circuit board!

Anyway fast forward a bit, I'm working at Convergent which was a nascent Intel's biggest single consumer of x86 chips. Intel was coming out with a shiny new version, the 80286, showed our engineers the spec. They complained "Hey! We're your biggest chip buyer but you didn't consult us on features!"

Intel guy said "Ok, what features do you want?" Our folks said "We'll get back to you..." Then they circulated a questionnaire among us software types for ideas.

I suggested "Let's get rid of that Intel Blue Box, have a feature in the new CPU that traps on bus condition mask and value registers." I even drew out what I wanted.

Well, what do you know, Intel did it. And it remains to this day, and is called "Data breakpoints". Probably the only thing I ever did that will last any length of time, since software has a really short sell-by date as a rule.
I don't think it's ever been about saving people from Covid, it's always been about saving hospitals from bad-but-eventually-non-threatening pneumonia explosions to the detriment of everything else they're supposed to care for.

I live in Hong Kong, where we have still a somewhat silly aggressive policy. We had 213 deaths for 8M people, so around 26 deaths per million people. Our hospitals never even felt the pandemic. Nobody is suffering of doubling inflation, ridiculous shortage or supply chain failures all around, but it's true we have less obese people than the US in the first place...

If the US didn't let their people free to have so many co-morbidities, they wouldn't pay such a dear price each time a cold mutates from a lab in China. Talk about a powerful country if such a small thing coming from here can knock them down, don't you think ?
I had strong memories of that time and never cared or engaged with something awful.

The thing is, this is subculture and past of some people. But not all people at the time nor likely majority of us.
