Most video editing software (that I've ever used) supports making clips or setting in/out points in longer videos. This doesn't necessarily make new trimmed clips as files on disk because that's expensive (storage and computation) depending on the video's codecs. Editors also expect to export a wholly new output from source so they don't need to make those intermediate clips. It's like pass by reference instead of pass by value.

On iOS the trimming is done losslessly, when you trim a clip it basically does the same as what `ffmpeg` is doing here. It seeks to the new start time and copies all the GOPs (group of pictures) to the new end point. The camera records video with really short GOPs so the trimming can be pretty accurate. Only if you apply filters or crop the dimensions of the video will the trimmed clip be reencoded. Any iOS software using AVKit can do the same lossless trims, I imagine most editors on iOS do.

When doing rotation I know the Photos app just changes the JPEG rotation flag in the EXIF data. If you send the raw photo to something that ignores or doesn't understand EXIF rotation you'll see just the sensor's default orientation. I believe HEIF works the same way (the container has a rotation atom). When exporting an image (reencoding for sharing or after editing) it will bake in the rotation to the image data, actually performing the rotation to the image.
As noble a cause as this current phone tracking may be, I'll continue to do what I've always done long before the outbreak of the corona virus, which mostly is to not take my phone with me at all whilst I'm out and about. If for some reason I have to then I do so with it switched off and only switch it on if or when I need to make a call (nothing's that important that callers can't wait, and anyway they can leave messages).

Frankly, I'm perplexed why people are so utterly obsessed with and hopelessly addicted to their mobile phones. Ask yourselves what you did before you had a mobile phone and you'll have to answer that you actually managed life quite well (or you wouldn't be here).

So did the rest of the world. We built the world as we know it today mostly without fixed telephones—from ancient Egyptians to Rome to the American Empire, and during the 20th Century we had no trouble screwing the world up big-time by organizing two world wars with ruthless efficiency, the great depression and the Cold War and, at times, we even advanced the human condition—and we did all this without the aid of mobile phones let alone a smart ones.

Of course, the obvious weakness in the 'Big-Brother' tracking everyone scheme—especially if there's a risk of heavy fines or sanctions for violators—is for everyone to just simply turn the damn things off before they leave home. Then, as with drink driving laws, the State will only catch and fine truly hardened addicts.

What would he do that for? If you recall, in January _zero_ people other than the president gave any shit about the virus. We didn't have any cases until something like January 19. 3 days later they formed the working group, and on Jan 31 they closed flights with China (Biden and liberal media called the move "racist"). To remind you at the time everyone was busy with third attempt at "investigation" and impeachment. Invoking DPA would be a bit "interesting" under those circumstances, and the dems would howl that he's "authoritarian", just like they are beginning to howl about it now, when there's end in sight for this. Do I need to show you the headlines and clips from end of January to lengthen your attention span? Pelosi handing out pens and inviting people to Chinatown? DeBlasio telling people to ignore coronavirus? Every single liberal media outlet saying Trump is overreacting and this is no worse than a flu?
The links are to two studies:

* A Large-Scale Effectiveness Trial of Reiki for Physical and Psychological Health. / Dyer NL, Baldwin AL, Rand WL.

* Effects of Reiki on Autonomic Activity Early After Acute Coronary Syndrome / Rachel S.C. Friedman, Matthew M. Burg, Pamela Miles, Forrester Lee and Rachel Lampert

The first study is indeed suspicious in that the tested population are Reiki believers/supporters who are obviously motivated to declare it to have had a positive effect. The second study has a much more limited scope.
Please don't spread conspiracy theories about real people. The former graduate student you mention has already been the target of enough vicious online speculation.

I wish Windows and MacOS included a Compose key by default. It's so simple that everyone could easily learn it, and we wouldn't have to deal with arcane Numpad key combinations on Windows or MacOS's super unintuitive and inconsistent symbol shortcuts.

I would suggest that you look at the region-level data for China, and just see if it looks anything like the European data.

For my money, I don't trust the US intelligence community but I still think that the Chinese numbers are somewhat implausible.

The charts show an identical dropoff in almost every region at the same time. We can see, from the European experience, that there's a lag between lockdown and case saturation. This does not appear in the Chinese data, which makes me somewhat sceptical.

Note that I'm not an epidemiologist, so it's possible that there's something else driving those numbers that I'm missing.
(Full disclosure: I am the Latacora person quoted in the article. While I didn't coordinate my quote w/ Latacora and speak only for myself, I've documented elsewhere in the comments[0] why I think the idea that Latacora and by proxy I would stand to financially benefit from HackerOne failing doesn't hold water, so I won't repeat that here, but I'm happy to have that argument there if you'd like.)

> It isn't in bounty hunter's interest to submit bogus reports. Where have I said it doesn't happen, regardless?

They clearly do: companies pay out for (and H1 triage regularly fails to filter) complete nonsense findings to the tune of several hundreds of dollars or more. If you can weaponize that process, you can make a decent chunk of change.

There's also no real reputational damage, as long as it remains trivial to Sybil all of the platforms. The platforms are disincentivized to stop that, because anecdotally "number of hackers on platform" is a stat that plays really well in their sales process, and it's a drum they beat loudly.

Finally, if you agree that it happens all the time, why do people keep doing that if it is truly against their interests?

Okay, so if I promise you you'd have a hospital bed and a ventilator for your last week on Earth, you'd go let some infected people cough in your face?

If your answer is no, you're still worried about the consequences of infection including death and permanent disability, then the public is still going to want to avoid infections even if ICU beds were completely unlimited.
You're right in general, but the "because" is wrong. You could say that the causality goes the other way (you should take care of your parents because they took care of you), but it would be more accurate to say that people just take care of family at every turn because that's what you do.

As a data point, my family (and most others I know) doesn't consider its member's wealth really separate. My parents consider their wealth as ours (the children's) too, my sister and I would spend all our wealth taking care of our parents if they needed it, etc.
Imagine if we hid some damn masks next time. We have to broaden our minds about what things threaten national security.

I don't trust the Chinese government but I think if they were lying then their opponents would be able to build a more persuasive case by now.
>The reason we don't build out of stone/brick, besides cost of construction, is that they're terrible insulators. So your heating or AC bill is going to go absolutely through the roof.

I'm writing this from a perfectly insulated 200 years old stone house. We've got access to a wide array of insulation technology in Europe, often in the form of panels that can be used to renovate an older building. And you can just blast insulation on the bottom part of a roof, which costs a penny and takes care of a most of your thermal dissipation. Plus insulation is getting subsidized when the government wants to save energy.

>"Solid" sounds like a big waste of money to me.

Paying for a paper house sounds like a scam to me.
When scraping just behave as to not piss off the site owner - whatever that means. Eg. not cause excessive load or making sure you don't leak out sensitive data.

Next put yourself in their shoes and realize they don't usually monitor their traffic that much or simply don't care as long as you don't slow down their site. It's usually only certain big sites with heavy bot traffic such as linkedin or sneaker shoe sites which implement bot protections. Most others don't care.

Some websites are created almost as if they want to be scraped. The json api used by frontend is ridiculously clean and accessible. Perhaps they benefit when people see their results and invest in their stock. You never fully know if the site wants to be scraped or not.

The reality of scraping industry related to your question is this

1. scraping companies generally don't use real user agent such as 'my friendly data science bot' but they hide behind a set of fake ones and/or route the traffic through a proxy network. You don't want to get banned so stupidly easily by revealing user agent when you know your competitors don't reveal theirs.

2. This one is obvious. The general rule is to scrape over long time period continuously and add large delays between requests of at least 1 second. If you go below 1 second be careful.

3. robots.txt is controversial and doesn't serve its original purpose. It should be renamed to google_instructions.txt because site owners use it to guide googlebot to navigate their site. It is generally ignored by the industry again because you know your competitors ignore it.

Just remember the rule of 'not to piss off the site owner' and then just go ahead and scrape. Also keep in mind that you are in a free country and we don't discriminate here whether it is of racial or gender reasons or whether you are a biological or mechanical website visitor.

I simply described the reality of data science industry around scraping after several years of being in it. Note that this will probably not be liked by HN audience as they are mostly website devs and site owners.
This is naive and childish maxim as argument.

Give FastAPI a try! You probably have DRF-Stockholm-syndrome like many do. The joy of having all pieces fit right in and be understandable and have validation auto-generated from type annotations (if you choose to) is a-f-mazing!

After using DRF quite a lot for quite a while I can clearly self-diagnose myself as being abused by it - such ugly patterns you always end up coding around and fighting the framework everywhere...

Use Flask if you're afraid of Python async, there's probably good reasons to be, never had to debug it in production... but LIKING DRF?! I cannot fathom that, I mean, one can like Django itself, it's good for what it was built to do, but what abominations ppl built on top of it instead of starting from scratch... ugh!
In general, concrete housing would have insulation. Though depends on the place of course, probably not in the Mediterranean while lots of it and triple glazing in the Nordics.

In Norway all communications with the government at national levels needs to be logged in journals that are publicly accessible by default. Not logging everything is a crime.

Personal details can be redacted, and some things can be marked as not for public view, but doing so tends to be inviting scrutiny, as the big media organisations have people trawling the post journals.
Yes, I'm willing to do that in the absence of a cure. I wouldn't like, go to a packed stadium, but I'll happily invite friends over or eat at a restaurant once it's permitted again.
Curious, does anyone know if the US govt is filling the reserve now, or even adding capacity? With oil so incredibly cheap right now, now is the absolute best time to be building and expanding our reserves.
This is the stuff most of us have to deal on daily basis. Do I just google the it and move on, or maybe I should try to come up with it my self? Every time I google, I don't feel any good at all.In fact,I don't feel anything.When I come up with some solution myself,It elevates my motivation and I always learn something new. As a manager though,I sometimes allow to do this stuff,while on other occasions I specifically tell not to spend time on some creative stuff and just get something off the shelve.
FFS fucking idiots.
The author nowhere claims that these things are universally applicable, and is careful to note many exceptions. If enough people read it and think the shoe fits, then it probably fits.
> When capitalism produces spectacular exaggerations of human cruelty, it has been corrupted. When a socialist system produces it, it is intrinsic.

Nobody blame socialism for cruelty in good faith. Cruelty has nothing to do with economic system.

What socialism (or any government trying to replace or severely restrict private sector) really does way more worse is empty shelves, deficit and terrible recourse misallocation.

There are more fundamental questions than the leisure ones like "who ownes what". Such as how come my parents lived in the second largest economy in terms of GDP and only few years later the whole country had nothing to eat, and we had a humanitarian crisis without any war or natural calamity.
>and most other professional occupations can easily earn $200,000 a year a decade

"Most professional occupations"? I don't buy this at all.
I hit that too: it was a known bug in SSMS and Microsoft released an update that fixed it.
The turning point is when the second derivative is zero, which would indeed be easy to spot with a second derivative graph. But it’s also very easy to spot with the first derivative graph (as published by the FT now): It’s when the first derivative hits its maximum.
I use a notes directory with multiple flat text files named in some brief but sensible way.

I alias a command ('showNotes') to open the directory in sublime and use sublime's search to search my text files or edit/add files as appropriate.

I use to just stick to plain text and code snippets but have started using markdown for newer notes.
In the case of Jurassic Park, I think Crichton's book was a lot better than the movie. One major difference between the two was the John Hammond character. In the movie he's a lovable naive dinosaur-loving manchild who meant well, and survives the movie. In the book, he's a cynical profiteer who brings children to the island in an attempt to emotionally manipulate his critics, and gets devoured by the most petty scavenger dinosaurs at the end. Relating to this, the book puts a lot more emphasis on the disaster occurring due to corporate greed, not science-run-amok.

I think a lot of modern critics of the movie might conclude that Crichton's novel was meant to be anti-science (this viewpoint presumably being reinforced by Crichton's later statements concerning climate science...) however I don't think that's an accurate characterization of the book. In the book the disaster is caused by greedy businessmen who cut corners, while the heroes are scientists who use their knowledge of science to salvage the situation the best they can.

I think "buybacks are not inherently bad" is a good point and still true in a theoretical perfect frictionless vacuum. But when we look at the entire economy and how all the money has been flowing mostly tax free from the government and workers to only (literally only) the super-duper rich via this buyback tool, then it's obvious we have a problem.
Seems so:

I don't agree with the conclusion here. We can draw the conclusion from this that it takes two months for lockdown to work. But that doesn't mean we can start loosening lockdown restrictions after two months. There's a causal relationship between lockdown and slowing the spread: if you remove the lockdown, the spread will rise again.

Some speculation: a big part of why lockdown takes that long to work is that it seems to take that long for people to start taking things seriously enough for lockdown to work. A few weeks ago in NYC there were still people coughing on each other in public and laughing about it, and my observation of a lot of people's behavior over time is that for some people, they need someone proximal to them to die of it before they will start complying.

I don't say this judgmentally. Personally, I probably didn't take things seriously for about a week after I probably should have, and looking back at why, it wasn't because I didn't care, it was a fear reaction--one very human reaction to something scary is to downplay it or pretend it isn't happening.

To provide some context, the US uses about 20m barrels of oil per day. We have about 35 days worth of oil reserves. It seems if there was some kind of extended emergency where we could not produce oil, 772m barrels would be wholly inadequate.
But will it help the article get the exposure it needs?
But the FT doesn’t display that graph anymore, only it’s first derivative. I liked the original graph (maybe I am better at deriving than integrating...)

"Developed and researched" tells me you did something interesting but I can't tell if it was resume padding or real work. If you can't articulate why, that's a red flag. A good hiring manager should be able to detect resume padding and avoid hiring people that waste company resources on pet projects.
I tried things with bells and whistles such as tagging, and embedding content and honestly it ended up just distracting me / creating more work for me to do. I found myself fighting with stylization, yak shaving small things when all I wanted was to jot down a link or idea.

I've now reverted back to just a flat files that I attempt to use markdown in. My home directory has a folder named Notes, that contains these NOTES.md and such. Write it in whatever text editor you want, but I mostly use Sublime Text. Email myself bits and pieces to transfer the data between devices.
I'm talking about starting a crash program to produce masks and tests, organizing a national system to redirect resources like masks and ventilators, etc.

Pretend that you're Andrew Cuomo on April 4, 2020. You're aware of what stage China is in. What would you do differently?
Every text editor has search. Tags are just words. If you put the text into the text file it is automatically a searchable "tag". If you want you can put some markup around it but it's really not needed.
I hate headlines like this. The oil isn't "hidden": the strategic petroleum reserve is a completely up front and public thing. There's no hiding going on. That word in the headline is just clickbait.
I use a low-effort approach based on the OneTab plugin, which doesn't involve tagging or categorizing in any way—just archival. See https://addons.mozilla.org/en-CA/firefox/addon/onetab/
or https://chrome.google.com/webstore/detail/onetab/chphlpgkkbo...

Basically, when you end up with 15+ open tabs at the end of the day and all of them were kind-of-relevant to your quest, but you don't have time to read them right now, just click the onetab button and they get put away for checking later.

I say to myself one day I will come back to this archive and organize/tag it properly but that day hasn't come yet ;) In the meantime the onetab list is very helpful for ad-hoc searches using CTRL+F (e.g. what was that blog post that explained X that I was reading last month?)

OneTab also has a "share as webpage" for sharing a "bundle" of research links.
