Your sources very accurately reflect the history that slavery was enforced by the legal system and peace officers upholding it. They don't lend any credence whatsoever to the notion that slave patrols morphed into modern police departments. The actual history is that police have slowly become more localized and detached from central authority (like the Kind or his officials - sheriffs, etc) over time as populations increase.
Every vaccinated person will not count towards herd immunity. Vaccines can be tremendously helpful in controlling infectious diseases, but not every person who is vaccinated will produce neutralizing antibodies. This is why it's important to vaccinate as many people as possible in order to surpass the herd immunity threshold.

At this time we don't know how effective any of the vaccine candidates will be.

That's a good point.

I think the Arch wiki is a good resource for this. My laptop is listed here - https://wiki.archlinux.org/index.php/Acer_Aspire_E5-575

I have the exceptionally cheap Acer E5-575g model (quad core i5) with RAM upgraded to 32gb and a 500gb Samsung EVO ssd. The touchpad is an Elantech.

If anyone knows another good site, please let me know - I'll be shopping for an upgrade early next year.

Software that is unique to MacOS:

- HoudahSpot (search files / documents)

- DEVONthink (document management system)

- Ulysses app (a markdown writing app; I know there are many, on many platforms)

- iA Writer (another markdown writer)

- Alfred App (automating)

- Keyboard Maestro (automating)

- AppleScript (automating)

- MailMate

- Things3 (task management)

- OmniOutliner

- OmniFocus

- OmniGraffle

- PDF Expert (reading / annotating pdfs)

- iTerm

- aText (text macros)

- Timing App (auto time tracking)

and many more.

Many of those apps have their equivalents in the Linux / Windows world, but their Mac pendents are imho much better.

Finally, it's the overall experience. Everyting is streamlined, everything works across iDevices, everything (mostly) works. I can't say it in a few sentences. Sitting in front of this machine, coding, writing, listening to music, that's a joy. I didn't have this feeling with a Windows machine (was a Windows and Ubuntu user until 2015).
Wow back to the UNIX morons. You're a hipster, basically just typing ls -l in the command-prompt all day, that's fantastic isn't it? You're "on UNIX" in the most retarded way. Get a real system. I recommend Arch, obviously, as any sane person would, but anything is better than Mac. Apple. How fucked up are you? Get a girl in some other way. No need to lug an apple laptop down the streets. Save you some money. Fucking asshole. You're a fucking moron dude. Get with the times and get with reality. Get a fucking whatever and install linux on it. You're just pathetic.
Ask HN: What tool does professional software engineers use to draw UML diagrams?
Hi.

I just graduated and am now involved with a (non-commercial) project where we are in the design phase.

I am using Visual Paradigm Community Edition to draw sequence diagrams since this was the tool I used in my uni classes.

I am not asking where to or not to use UML diagrams. I am asking which are the best tools to draw them.
photomultiplier tubes. At the time the effect was discovered, PE was recognized experimentally (and exploited), but unexplained, and once it was, development of PMTs (critical to a wide range of practical technologies) was greatly sped up. This led to high quality television cameras not long after...

Apps shipped with macOS are actually good imo, or there's just not a lot of better alternatives. Never found a better alternative for itunes or mail (used Thunderbird and mutt for a while and they're either bloat or have bad UX). macOS designers seem to be good at cramming functionalities (i know it's not unix philosophy) while making it not look bloat at all.

I've read Metamorphosis many times over the years, and I've come to the conclusion that it's a very subtle dark comedy. But of all the punchlines, including the ending, are (for lack of a better term) situational. I can't explain further without spoilers, so HN might not be the right format for it.
There's a bit of a difference between "not saying things because you may lose a dozen of meaningless internet points" and "not saying things because you can have a mob of haters try to get you and you family fired, you life ruined and maybe send men with guns drawn to your home to get you murdered if they're lucky".

What a strange comparison. Why would you compare it to a space telescope when you could compare it to another supercollider, operated by the same organisation?

The Large Hadron Collider went over budget by about double, which is bad but frankly for these sorts of cutting edge systems hardly unprecedented. Some of that was ironically due to budget cuts causing delays which in the long term increased costs.
One wonders what criteria the Times must be using to determine that it's worth putting Scott at credible risk for further harassment but not women gamers.

Applications and hardware drivers on Mac just work. Even Homebrew works pretty nicely. The visuals of Mac are vastly superior to any flavor of Linux I've tried: smooth graphics, font rendering, HiDPI support, etc. Some aspects of Mac hardware (screen, touchpad) are very hard to come by with other manufacturers.

At this point I'll probably switch to Linux as soon as my 2015 Macbook stops working, but I would've really liked to stay with Apple.
Some people probably have some write-off system, or perhaps resell them why the devices still have some value so they always are somewhere 'in the middle'.

I personally tend to keep my most recent device and the new device at the same time for about 2 years because of vendor lag (happens a lot with those classical software vendors that take months between software releases) and because I need the ability to compare between versions of both hardware and software. The newest device gets promoted daily driver (usually many benefits there, as they often are lighter yet more powerful). In general it means 2.25-ish devices per 10 years.

Other hardware, like SBCs tend to rotate out slower, but generic x86 platforms rotate out faster because if a critical component fails the labour for finding parts and replacing them is too much vs. buying up to date replacements. Luckily, due to lower usage of those machines they last longer, so technically the Apple hardware made the non-Apple hardware have a longer lifecycle in my case.

There is some irony in there as I do provide board-level repairs and the machines I work on for other people are ones I'd never personally invest in.

Nothing can be upgraded on Macs - SSD, memory. Maybe Mac users do not care, but the most annoying thing about this is that others are copying Apple. Even the legendary thinkpads, some of them are soldered and non upgradeable. Even the screws on Macs are non standard. We've to use dongles for everything.

For this alone, it is better to get windows hardware. They are pretty good these days and cost a lot less. Plus there are lots of interesting things going on - second screens for example.
Wow this is very impressive. I wasn't expecting the lighting stuff and was amazed.
The current system benefits large companies and detriments small developers, so I think it would probably just open the door for large companies to take over all the popular extension types.

If uBlock Origin stopped supporting Chrome, AdBlock would fill that void. If Honey has problems, an executive from Ebay calls an executive from Google and it's fixed instantly, so there's no incentive for them to participate. In fact, anyone making a decent amount of money isn't going to want to change the system.
Let me please chime in. As AdGuard developer, I'd like to comment on what you said and explain some details about how it works.

First of all, AdGuard desktop and mobile apps are quite different from hosts files or pi-hole. For instance, they're also able to apply cosmetic rules. Also, and this is really important on Android (unfortunately we can't do that on iOS), AdGuard is able to apply different rules depending on which app makes a request.

The common example is dealing Facebook Audience network. If you need to block Facebook ads in third-party apps with Pi-Hole, you'll have Facebook official apps broken as well. With AG, you can keep the official FB app working and block it in third-party apps at the same time.

Second, on every platform save for iOS, AdGuard filters every network connection and not just DNS queries. There're already multiple examples of apps (for instance, TikTok) that switch to using DOH when they detect that there's DNS filtering messing with their domains. Eventually, every network-level blocker, pi-hole included, will have to control all connections as DNS simply won't be enough.

Regarding Pi-Hole, we actually maintain a free and open source alternative called AdGuard Home: https://github.com/AdguardTeam/AdGuardHome

Fairly easy-to-capture. Can be very coarse-grained and still have lots of meaning.

(note: get this one ironed out before trying to calculate a Velocity metric)
My reading of this, in context with the previous bit, has a subtle difference:

With contact tracing, you get contact data from person 2 and you keep that data. Then you get contact data from person 3, and you keep that data too, and by the time you get to person 4, you have fairly strong evidence that person 1 is an asymptomatic carrier and you can do that without quarantining anyone asymptomatic.

With exposure notification, you get contact data from person 2, and tell everyone they were in contact with, and then throw away that data. Then you get information from person 3 and you notify everyone they were in contact with, and then throw away that data too. As a researcher, even after person 8 you don't have any evidence that person 1 is an asymptomatic carrier (because you threw that evidence away at each step) and the best responsible asymptomatic people can do is assume they're asymptomatic carriers whenever they receive an exposure notification--they'll never actually know.

The key differences (which I italicized above) are:

1. With contact tracing you keep all the data you collected. With exposure notification you throw away the data after notifying contacts.

2. With contact tracing you have to have proper security to store a bunch of private medical data. With exposure notification you don't.

3. With contact tracing you can identify asymptomatic carriers. With exposure notification, only the asymptomatic carriers have the information to identify themselves (assuming they keep all their exposure notifications).

4. With contact tracing, people don't have to assume they are an asymptomatic carrier, because the person doing the tracing will notify them if they are. With exposure notification, your only option is to assume you're an asymptomatic carrier for two weeks after every exposure, because no one person has enough information to identify asymptomatic carriers.
Uhhh.. what? Like, can you give some examples?
Thanks for the kind words. May I ask what specifically you find interesting about Glamorous Toolkit?
Look, I do not know your experience but I am glad you can say that I am a misanthrope. This helps in the discussion.

I work for 25+ years in IT in huge technological companies. I can tell you that in these technological companies the level of knowledge about things above the very basics (and how to use a bookmark is way above that) is poor to say the least.

This is something I know very well, not some kind of vague deliberation. If you have managed IT operations in a large company you would know. I therefore assume that you do not.

Now - expand this to the whole population.

And as for the car - I had to check if I had a spare a few weeks ago, when the car mechanic who was coming to fix my punctured tire asked me. He had to direct me as to where to look. I am probably an idiot, of the kind of idiots who are not interested in cars. But I do not call the ones who are not the same.

Thanks to Mr. Tonsky's post mandating me to upgrade to a 4K monitor for sharply rendered fonts, this is awesome. The text is bleeding-edge sharp.

I got the least expensive 27" 4K@60Hz monitor I could (Sceptre U279W-4000R, $200), and it arrived with no dead pixels. I had to find a color calibration profile, but now it's a beaut. Thanks to Mr. Tonsky.

The point being addressed was fear of murder/assault From officers being a primary concern over fear of murder/assault from non-officers...I think we want to look at absolute numbers, you are either going to be murdered or you aren’t and assuming every single police killing was a murder 90% of murders are committed by non-officers. Why would we need to look at how many murders per 100,000?
I’ve said this before, but I think that a lack of physical modeling might be the key barrier for AV technology. Human drivers have a mental model of physics that they’ve honed for 17-18 hours a day since they were born.

I'm a lawyer, but I can't give legal advice here. See https://notlegaladvice.law/.

If you're interested in the issue, however, you might start by reading a little about "money transmitter" regulations. An early payments platform for open projects shut down at least partly on account of it. I suspect the concept of "perks" became widespread in part to differentiate fundraising platforms from money transmitters.
So in response to a post saying that “Apple never got sued for slowing down iPads”, you post another link where they got sued for slowing down a number of iPhones.

Not something to be impressed by; gifts are tax free in the US under $15,000 per one year.
Police in england are an evolution of how the King's peace has been enforced, starting, very simplified, from when the King himself enforced it in very early days to delegating it to members of his court and his sheriffs, and ultimately to localities and special departments of the modern day. Cities did not generally have a "police department" but they had the sheriff and whoever the sheriff commanded into service to enforce the peace. As populations have increased the enforcement of these duties have evolved to be taken on by more local organizations that are modern police departments.
I'm not an accountant or tax lawyer, so this isn't advise, only my back of the envelope calculation, not even using things like the 172 deduction, or business expenses, but my estimate was actually way off almost double.

Gross Income: $112k

- SEP IRA 25%: -$28k

- Owner Health Insurance: -$15k

- 199-A Deduction (20%): -$12k

Total business income for taxes: $47k

- Married Filing Jointly Deduction: -$24k

- Total taxable income: $23k

Tax on $23k (10% of first $20k, 12% of next $3k): $2360
Indeed, that is shitty cloggy.

I feel like embedding a web assembly runtime and then exposing scripting API to it would give you similar benefits (you would have to add a compile C to WASM step before loading) while giving you a really secure sandbox.

It is more complicated than just embedding a scripting language (or a scripting compiler :)) but more general and secure.

Especially if WASM evolves to a point where you can compile C# and other high level languages to it (you can to a point already but it's not on par with native runtimes) - it would be the most general embedding runtime.
The absolute last thing you would want to do to someone armed with a lethal weapon would be to antagonize them with a weapon that won't consistently eliminate them as a threat.

These "less lethal" weapons aren't being used to defend against actual threats, they are being used to terrorize unarmed protestors.

> As a consumer, I've never used a React Native app that I liked using.

If it is a good react native app you won't know it is RN.

If you notice it, it is by definition poorly done. There are some things (e.g. specific animations, UI elements) that RN just isn't great at, the best way to avoid making a janky app is to avoid even trying to do those things.
Having an aged population certainly helps. Not a lot of 80 year old gangbangers.

Lizabeth Warren's Campaign Is Making Its Software Open Source
I understand that the police need to be reformed, and that they disproportionately police the poor. There are much better options than withdrawing them from all poor neighborhoods though. As we have seen time and time again, when the police are impotent, someone else will step up into the void to provide security. Typically, that's either organized crime, or (worse) vigilante justice. The net result is always the same though: the people living in those communities are always worse off.

Edit: I guess I should propose a solution instead of just railing against this idea. How about we: 1 - end the war on drugs, and 2 - fundamentally address poverty for once in this country.
>Apples open source devtools are old as dinosaurs, so that might be a common case.

Yeah, but there's a certain expectation that the tool that you have installed in /usr/bin is a certain version. There's a reason why tools like Homebrew generally do not overwrite built-in tools.

If you just replaced /usr/bin/python with Python 3, you'd probably break all kinds of things.
Exactly this. Let’s assume you have a computer because it helps you in getting tasks done.

In Windows, antivirus bloatware and ads in your start menu stand between you and that goal. Third party software is often of very disputable quality and design.

In Linux, it’s always a surprise what thing/dependency is suddenly broken on this boot, and what arcane commands I need to fix it.

On macOS generally I boot my machine, click on the app I need to perform my task, the app will be of sufficient to very good quality, I do my task and I’m done.
Those numbers can be seen as the minimum, the same way the reported number of COVID related deaths are the minimum. The actual numbers are all but guaranteed to be more.
It went all downhill once a computer became a smartphone / tablet and the common mass accepted that not being to upgrade them is normal. And now we have mac mini's with soldered ram and soldered cpus and even soldered ssd's and batteries that cannot be removed. The huge amount of waste that this generate is so upsetting.

Wish more efforts like the Puzzle phone in europe would bear some fruit.
Many expenses related to the operation of the business become tax deductible. At minimum, that usually includes internet access, hardware/software upgrades, and potentially some % of your living space dedicated to the business. If you do it properly (usually via documentation), you can often include miles driven to meetings, professional travel, meals with customers, prospects, and contractors, and a ton of other things.

And still none of that considers things like Simplified Employee Pension Plan (SEP), health insurance, home maintenance, etc, etc.

The list can go on and on depending on the type of your business, jurisdiction, and supporting documentation.

* Talk to someone about your local tax rules before taking action.
Keeping the peace was a concept in both countries when they split and was the duty of the sheriff which still exists in both countries and is actually still very functional in the US. That some localities with very large populations evolved an even more local office for keeping the peace is entirely consistent with the evolution of police tracing back to England before it existed as a modern concept. The simple fact is that slave patrols just did not morph into the general-purpose peace keeping organizations that today we call police.

Ok, I think we just disagree on what is journalism and that’s fine. The Opinion page is not journalistic, it’s just other people’s op-eds selected by an editorial board and said board is not immune from either bias nor criticism.

The rest of the paper is generally outstanding, though they have some high profile screw ups. Can’t trust anything 100% ever, but I don’t think this incident reflects on the rest of the paper. Regular NYT subscribers (myself included) already know what they’re getting in Opinion, and I personally think it’s trash.
In the US lawsuits typically open with the closest thing a lawyer can imagine to infinity dollars of damages, and then you have to have your lawyer work it down.
I used to have that faith too, but the stories that have been coming out recently have made me doubt almost all reports provided by police and coroners, even with cameras in place. What motivation do they have to provide accurate information, without any third party oversight?
