Human foveala, the central part of your vision, has on average about one cone every 30 arcseconds, but resolution of 20 arcseconds is still quite common because the variety in cone density is quite high. So someone with good vision, maybe someone who would naturally be inclined to work in graphics, would need over 430ppi at 2 feet, or 290 at 3 feet. This screen seems to be perfect for someone with good vision at 3 feet, if you place the screen closer you would need even higher resolution.

But the past didn't use ASCII as such, but extended character sets, or multiple characters sets, which did allow for Russian, German, etc. text interfaces.

Someone who is good at learning can just learn for free, only someone who is not confident in their abilities would pay for the name of a college attached to a degree (with likely less actual skills transferred, because paid colleges depend on throughput, not on results). The actually good students at paid colleges are the ones who got a academic scholarship, i.e. free like community college.

As mentioned it works for valid short hashes, if there are multiple commits with those first 5 characters then you need to make it more specific by bruteforcing, appending a 2, 4, 7, or 8 will lead to a valid commit.

It seems like the first variant is overly complicated. When you write about set theory you should be able to figure out that you don't have to rely on the effects of the union operator, the result you want is a simple difference with previous levels of the recursive cte, or a terminal query that groups by the table and shows the minimum level

And of course it can also be used for gaining entry to hackers systems by infiltrating c&c servers on third party hardware, which also had been done before by Dutch authorities without any existing legal framework to allow this.

I suspect this is also to provide a legal framework to automatically remove malware from victim's computers, as has been done before by Dutch authorities without any law permitting such actions, and removing malware is obviously good for society.

> Also had a 2:1 desktop:laptop ratio -- would have guessed more laptops. (The author questions how Plausible determined this.)

For my personal analytics without third party dependencies for privacy reasons I use the fact that Javascript allows access to the battery API, so a laptop uses a desktop browser, with a desktop resolution and zoom, while still having a battery.

You could use the name of the foreign key, together with FKs namespaced to the table they are on would allow very expressive joining, and the query might even survive schema changes. ORMs tend to work like this.

Then they are that much more likely to need you. There is no reason to think that layoffs and hiring have anything to do with eachother.

Rizz — Sun, 18 Sep 2022 20:26:28 +0000

A modern phone with a 5 Ah ( ~ 18.5 Wh) battery can run for many hours streaming to a builtin screen, meaning it uses far less (anything over 45 minutes is more energy efficient) than a chromecast despite doing more. Same scenario with a laptop with a 60 Wh battery, which can also run a long time in idle, and even while streaming, and is able to resume from sleep in a second. Running more than 2.5 hours on battery means it's more energy efficient than a Chromecast.

If the converting to hex step is too slow, could you leverage your makefile or other build script to bootstrap a simple, faster converter to convert your data file?

MS Access works just as well on an SQL Server database as on its internal database, so your scaling works just as well as on any other established database server, and then the SQL dialect is T-SQL, which is reasonably standards compliant.

Is it crime or is protest? We all know Amazon will let its workers die in hurricanes, harass its workers until they commit suicide, not pay their workers a living wage, and all this while the big boss goes flying around in spaceships for fun. I'm sure a lot of the "criminals" rationalize their behavior by knowing that whatever they do it can't ever be as bad as what Amazon does, they're even doing justice by fighting back when no-one else does. I'm sure this is more about being Robin Hood than people being evil to their core.

Find was first added to DOS 38 years ago, years before POSIX was created, and even more years before grep was added to POSIX. Find's capabilities were kept as is for compatibility, newer, more capable, utilities have been added over the years like findstr and select-string.

Rizz — Mon, 12 Jul 2021 20:48:23 +0000

The Netherlands just tried reopening, in two weeks they managed to undo seven months of lockdown as far as caseload goes. The infections are overwhelmingly amongst teens and people in their twenties (over 90% of new cases), who have not yet had their second shot or opted for Jansen vaccine, which doesn't protect as well as the others.

It would be very unwise for England or any other nation to follow in the Dutch footsteps.

17 in php with strlen, which is defined as counting bytes. 1 when you use grapheme_strlen. mb_strlen and iconv_strlen return 5, and 5 is rather useless as the article says.
