The authorized absence rate seems to be just above 3 %: https://explore-education-statistics.service.gov.uk/find-sta... which amount to ~ 3 days of absence per term/ ~ 6 days per year. 6 * 12 = 72, which is quite a bit

Probably didn't want to go the AWS route of just buying a pile of IPv4 space from established organizations.

Well, at my previous job, the company was blackholing 1.1.1.0/24 and others in the 1.0.0.0/8 subnet because that was the previous LAN. Thankfully, I have done an audit and removed this nonsense.

A case could be made that sharing an IP address is like sharing a cell phone number, only that you don't get to make the decision directly. By choosing a provider that has not enough IP addresses to hand out/ hasn't implement

Well, not going to such a school might be more beneficial in the right family setting than going. Also, if you think that 3 months out of 12 or so years of schooling will "abandon the kid and their future" than we should probably

Actually, e.g. sodium could be great for energy storage as a metal as well. There are long expired Lockheed patents about how to turn sodium with water directly into electricity. Other processes, that already work on industrial scale could

Yes, at OrgPad, we are writing our own rich text editor and if you want to use the DOM approach, you don't have much choice than to do it like this. You can see the WIP demo here (in Czech but it is quite visual): https://ww

I like the hacking mindset to make something work even if the odds are against it but the better approach would be to fix the DOM APIs and to do the necessary performance work instead of basically throwing all the responsibility on some lib
309.
by kaliszad 5y ago
Yes, DOM is "just" HTML and CSS with a JS API. All of that is quite broken in various places, the APIs usually rather bad, mutability everywhere and performance suffers as soon as you e.g. switch the cursor from an arrow to hand&#

The comment in general may be true but I don't see electricity costs being "much greater than CPU purchase costs over the lifespan" at least not for a data center operator. The AWS M4 EC2 instance uses "2.3 GHz Intel Xeo

Clojure specifically doesn't have the bracket wrapper around condition-expression pairs but syntax highlighting/ formatting considers it and aligns stuff nicely. I don't think, it is a problem that it basically is a list or f

by kaliszad 5y ago
Well yes. Clojure in general tends to have less special syntax and in general is designed very consistently. What I find very useful is the threading macro ->> and -> which basically is a pipeline: (-> something (manipulation-of

That might be true but good variable names and some terse but to the point comments are much more helpful in my experience.

Yes, Safari is a pain. There are other and much bigger pains in the browser ecosystem in general, let me give some examples: - The DOM is very slow/ inefficient and has a terrible API, basically owing to the mutable, object oriented wa

Well, three things on that list are languages that are basically DSLs (Shell to a degree, SQL) or Markup Languages (HTML). Comparing any of those to e.g. C++, Go, Ruby or Python is like comparing apples to oranges and I don't see, how

Having at least a tiny bit of DevOps knowledge can save you a ton of money. Actually setting up GitHub Actions with a special SSH key-pair just for the deploy in GitHub Secrets took me a few hours from 0 to full deploy of code. I haven&#x27

It doesn't have better resiliency, when you just need more RAM than it can offer at reasonable cost. I mean a comparable VPS is more than an order of magnitude cheaper. It is not the best advice to burn money on infrastructure, if you

by kaliszad 6y ago
I actually would recommend not using Heroku (after we used it for the first few months literally starting from 0 users at that time) at all if you know at least a bit what you are doing. Just get a VPS somewhere and run on that. You will ea

Great point! Actually "scalable" in any direction is meaningless until you provide the scale, performance, reliability, cost and time requirements you have to consider while scaling. A single server for a typical web workload is j

I tried just now in two different Firefox (ESR and current) versions and it works. Perhaps you have to enable JavaScript, since OrgPad is a web application? You can also try this not-shortened link: https://www.orgpad.com/o&

Actually, the one thing that I as a systems engineer really like about Clojure is the threading macro (-> some-data some-function-applied-on-some-data some-otherfunction) or (->> ...) for inserting not as a second, but last argumen

There are many, many networking and originally UNIX tools tricks (e.g. SSH) you can show to the poor people supporting industrial networks/ hardware. I have written some of my tricks down in this OrgPage: https://www.orgpad.

Usually, inbound IPv6 are firewalled by the ISP router just fine. As far as I know, there is UPnP with IPv6 though there seems to be some work into that direction. Also, current CGNAT setups tend to close connections before they should acco

by kaliszad 6y ago
@yesco is right that practice is all over the place for IPv6 if it works at all. But in general, IPv6 as a protocol is just fine, at least equally secure as IPv4 and not more complex than IPv4 in many practical cases. I would even go so far

Yes, coax based connections can be quite fast but in practice the chipsets supporting DOCSIS are quite bad or the (usually closed source) firmware is very buggy or probably both. I should know: https://www.phoronix.com/scan.

Yeah, the whole Spectre/ Meltdown was handled very badly by Intel. Illumos, OpenBSD and others basically found out from the media/ mailing lists of other projects where people were told under NDA. Not a great position to be in, th
