Smalltalk is surprisingly OK to develop on the phone. I've written a little on-screen keyboard in Smalltalk (subject of my next blogpost; [1,2]), and it's just a naive qwerty layout, but it works OK for the short methods common to Smalltalk programming. Very early days, plenty of improvements to be made, but I was surprised that it wasn't an immediate fail.

What are the good resources for learning C++?
Hi All,
Could someone please suggest regarding the resources to to learn c++ and its advance concept.
Thanks
If you want to remember something for a long time you should use spaces repetition for the method of loci.
> Trying to make kids learn programming without them being interested is about the parent wanting their children to be like them

That's harsh. I'd say it's about introducing their children to something they enjoy/find valuable, in the hope that the kid will enjoy it (or get value from it) too
I was surprised by this and I don't think your sentence is entirely clear, but the ending figure seems to check out. I think it's more clear to say "the radius of a black hole increases sub-linearly with its mass" (specifically, the square root of mass).

Sagittarius A*, the closest black hole, is 4.1 million solar masses, so its Schwarzchild radius is 12.1 million km, so its density is 0.25 kg/m^3, which is about 1/5 as dense as air at sea level--much less than water.

A black hole made from Jupiter would have a Schwarzchild radius of 2.8 meters, so its density would be... denser than a neutron star.

GitLab won't support if you lost your 2FA Code
DMA stands for Direct Memory Access, and it is called so for the fact that the peripheral device directly read from or write to memory bus while CPU is not accessing it. So CPU internal states or protection are in theory irrelevant.

In a most rudimentary implementation, a device doing DMA is physically wired to the main memory in parallel with CPU. The device will set something like `data, addr, CS, WR = 0xCAFE, 0x1000, TRUE, TRUE` and send a clock pulse. Then when CPU comes back to check address `0x1000`, the data `0xCAFE` is magically “there”, so programs on CPU don’t have to waste cycles polling the device to get the value. Naturally, some arbitration is necessary because trying to change bus states from both sides will mess things up.

Above was probably the case until 1980s or 90s, and DMA in modern days instead goes through bus masters and memory controllers. Since it’s not going directly to physical RAM anymore, such controllers can be configured in such ways as to prevent unwanted accesses.

But it’s more of “can be used to protect against”, not “won’t be possible if done correctly”.
That sounds very promising, thanks! I'll definitely check it out.

Does it work as well for non-native speakers though?
Yea reverse all acquisitions you guys approved cause you know at the time you were for the Big Tech and now you are against it.

What if the Joint N-11 does not work on the body?
Joint N-11 contains Niacinamide in the most flawless structure. It additionally contains two intensified fixings which are called retention mix and fast help mix. The retention mix encourages the body to retain Niacinamide completely and the quick alleviation mix works with the ingested Niacinamide to give your body a quicker and successful help. All these work as one on your joint agonies and viably decreases the torments and aggravations quick. Joint N-11 additionally makes your joints including your wrists, knees, hips, back, and neck entirely adaptable. https://apnews.com/press-release/ts-newswire/7864232eaa90aa0...

I've done something a bit like this for "career days" for elementary school kids. I coded up a perl script that was basically something like this:

#!/usr/bin/perl
$score = $ARGV[0]

if ($score > 90) {
print "A";
elsif ($score > 80) {
print "B";
elsif ($score > 70) {
print "C";
elsif ($score > 60) {
print "D";
} else {
print "E";
}

And I'd ask, "What do you think happens if you put in '85'? What about 10000? What about -30?" If the group I was talking to seemed pretty sharp on the uptake, I'd ask, "If you wanted to hack it so that people who got 95 got an E, and people who got 50 got an A instead, what would you do?"

The kids really seemed to enjoy that. Apparently they even told the teachers I was teaching them to hack programs -- a bit concerning for the teachers, but mission accomplished as far as I'm concerned.
Just add 2 to all of the numbers and call it a day!
Interesting theory. Let's agree that it's inconclusive then!
Startup School ran a "skill test" once, for founders, in association with triplebyte. In exchange for something very trivial ("YC interview") you now give them the license to judge your "skills" for a lifetime. Even if not that, it seemed like a very inappropriate, unnecessary, dishonest bait. Yeah, no thank you very much.

I work with someone who does all these things aggressively: super polished code, always talking in slack, always talking in meetings. My impression is that he doesn't actually produce a lot of code, but he's very impressive to management because he's constantly giving his opinion and overcommunicating. I find it insufferable.
> The H1B visa is a temporary worker visa. There is this whole legal fiction where, when you get one, you have to announce non-immigrant intent with a wink, then once you’re here you say “I just now changed my mind and I want to stay here, can I get a green card.”

This is not true. Your description is accurate for the F1 student visa and TN work visa for Canadians - applicants for those visas are not allowed to have immigration intent. There is no such requirement for the H1B visa.

The poster you replied to is spot-on about the ridiculous wait times for green cards, and this delay has nothing to do with the H1B program itself. The government really needs to speed this up, so that immigrants and their families aren't living in fear of the next arbitrary Trump executive order.
I like the idea :-). Hopefully the commitment to one idea will pay off

You can use the [doctl](https://www.digitalocean.com/docs/app-platform/references/co...) CLI along with an app specification yaml to deploy from your self-hosted GitLab.

The App Specification supports a normal Git repository. However, I can see how this might be a problem if your repository is private as there are no configuration options for auth.
There are half-height dishwashers, and also ones that fit on top of the bench, but they are both generally bigger than would fit in a sink.

Look I don’t want to criticise but I’ve got to say, this is the sort of thing that makes kids hate programming.

“Hey kids ready to do some super exciting math in a computer program?” Nah.

I had a computer teacher who managed to make me bored and disinterested with stuff like this, despite me being crazy crazy crazy interested in computers.

The best way to teach kids programming is via programmable graphics I.e visual games making systems. Not written code.
Another awesome thing about Squeak Smalltalk: the total amount of code I had to write for the on-screen keyboard was 234 SLOC :-)
What about Feng Zhang?
> You seem to think that the H1 program should place candidate 1 over candidate 2.

The bodyshop spams the program with a zillion and one replaceable cogs (from the perspectie of the bodyshop).

So if you compare C1 with all of the alternative C2 options submitted by the bodyshop, the C2 selection is many times (even hundreds of times!) more likely to get picked.
PHP, Apache, MySQL (or MariaDB), Bootstrap CSS and jQuery.

Very good setup that will solve your problems relatively fast and can be running for years without much maintenance.

There is no point of using anything else to do webpages. These technologies are tested and tried and works. Tons of documentation.

Ignore ideas that says you need to use fancy modern technologies, that is what has ruined the web and web development.

What is important is to follow best practices and web standards and that is true regardless of what technology you choose.
Right, while I don't live in that area, I do live in an area with a similar cost of living (Key West), rent on a decent home running near or above 3K and an apartment / townhome in the Key West Oldtown area can run up to 4K. Average dine out meal runs around $30 a plate and fine dining in the area of $50 a plate and up. Don't get me wrong at SV salaries they are not living hand to mouth but when you see those rates from a different cost of living area it can seem like ridiculous numbers but the reality is $150-$170K in that high of a COL area gives you enough to get a decent apartment in a reasonable commute distance, some pocket money for entertainment, healthcare, the ability to put away for a rainy day and it you live modest enough to pack away some retirement. The reality is that should be the base standard for a job. People should earn enough to provide for themselves, and secure their future. To me the fact that, that is no longer the norm in the US is what is shocking. An honest days labor, should command and honest wage, and to me those are the minimum things that should be secured in an honest wage. I see people down here in the FL keys working 2 jobs as the norm to make rent and to pay for the here and now, they cannot even fathom healthcare, rainy-day fund and retirement is not even on their radar. These are not people working restaurant or construction jobs, I see many "professional" jobs moonlight as bartenders, etc.

The drug-discovery venture I lead goes into some detail on grapefruit, hesperidin, and naringin in context of drug interactions at the end of this article in Medium’s An Idea publication (just scroll
to the graphic from the FDA):

https://medium.com/an-idea/enter-flavonoids-f42662810c11

Conventionally was thought that the main culprit was bergamotin; but subsequent research showed that naringin (citrus in general but grapefruit especially) and hesperidin (citrus
in general - orange, lime, lemon) have their own important interactions with drug-metabolizing enzymes.
Yes. I use gnome personally and macOS at work and both default calculators are not nearly as nice to use.

I'm currently looking at moving to the US next summer and I can't believe how awkward the process is for me. My partner is starting a 2 year postdoc at Stanford and I can get a J2 visa to go with her, but then need to apply for a work visa which can take several months to process. I currently work remotely for UK-based companies earning around ~$100k including overtime/freelancing work yet I'll have to quit these roles rather than just take them with me. Because I don't have an undergrad degree I'm unable to get a normal work visa or have my employer relocate me.

I wish there was some globally accepted visa like what Barbados has recently rolled out where if you earn over a certain salary remotely you're allowed to move there for a finite time period as you'll be able to contribute more than if you were unemployed and waiting for a work visa for a few months.

If anyone has any advice on how they did something similar I'd really appreciate it (I'm from the UK).
I think the best solution is CSP _and_ injection mitigations - even without XSS there is still DOM injection which can be equally damaging reputationally.

iirc, IE11 (under Windows 7, specifically) does not support CSP. I don't think CSP mitigates all XSS vectors either (`<a href="javascript:alert(1)">` for example). Sure IE11 is deprecated but that doesn't mean you don't need to account for it when building an enterprise application.

I'm curious if you can provide any details on what / how Safari was exploitable with CSP - https://caniuse.com/?search=content-security-policy indicates that it should be pretty uniform across popular browsers. If you'd prefer a private channel @yoloClin on twitter.
When you say it like that it sounds like people are begging RedHat to step in and do their tech support for them. When in actual fact in the case of things like libinput and systemd they were developed at RedHat and I imagine that they also exerted some influence to increase their adoption. In these specific cases (high profile projects with a few noticeable issues) it makes sense to go back to the people who developed and maintain them to say "Can you please fix these issues"

Yeah my kid is around the same age as the OP (kindergarten) and seems like he will be interested in coding some day, but just isn't there quite yet! I didn't get into coding until much later, probably 11-13 like you said, and it didn't hold me back!

We're just trying to meet him where he is at and try to make sure he is being creative, whatever it is.
There was a really interesting debate here on who should get credit for the patent (Charpentier & Doudna vs. Feng Zhang and to a lesser extent George Church, i.e. discovery + characterization vs. making things practical). I find it interesting, but not surprising, to see that only the former are getting the Nobel Prize.
This is always great until there is a bug somewhere in the infr layer. Then having k8s is no longer such a good idea.
> At least retarded is technically right...

Mentally retarded as a phrase is no more "technically right" than "moron", "idiot", or "imbecile". All medical terms that preceded "retarded" for describing intellectual disabilities. You just like it because it happens to be the term that was being used at the time you learned it. It doesn't make it any more right or wrong. There is a medical term for the concept, its starts to become widely and popularly used as an insult, the medical profession comes up with a new term.

> Up until around the 1960s, the terms "moron", "idiot", "cretin" and "imbecile" were all genuine, non-offensive terms to refer to people with mental intellectual disabilities and low intelligence. These words were discontinued in that form when concerns arose that they had developed negative meanings, with "retard" and "retarded" replacing them

I agree with CSP, but as I've commented on another thread I recommend CSP _with_ other mitigation factors due to DOM/HTML injection, and browser support.
You and everybody replying to you are making the same baffling mistake, i.e., assuming that technical/song writing ability/education = star. If you want technical ability, there are 8 year olds on YouTube with better chops than EVH. Possibly every 8 year old has better chops than Kurt Cobain. But technical ability does NOT make you a rock star. Same applies to the other fields you mention, painting etc.

I'm sure young rock stars (in the same vein as EVH, Axl, Hendrix, Cobain, Morrison) would still exist as the personalities and talent are still there, but rock is not mainstream anymore, so they can't exist. The closest thing to real rock stars now are the likes of Justin Bieber.

You should re-listen to the Beato/Satriani clip you told someone else to listen to, because he essentially says this. The artists you suggest are irrelevant and can not be compared to EVH in any way whatsoever. Guthrie Govan?! Van Halen drove mainstream culture. Nobody outside of guitar forums know Guthrie Govan. The other suggestions in this thread of comparators to EVH and Chris Cornell (Tosin Abasi, Petrucci, Belamy) are just embarrassing.
Even for "some innocent stuff like Tylenol", as the original comment puts it, you do not want to be taking 5x the dose. This is a very harmful drug in (not very) large quantities.

I know of somebody whose boyfriend ended things with her, she took a load of tylenol to end her life, but the doctors managed to resuscitate her. When she came to, she said to her mother "I'm so glad I didn't kill myself over that bastard". A week later she died from liver failure.
"Java Edition" is, assuming the system can run "modern" games decently well.

I've also heard good things about "ro blocks", but having watched a stream or two I'm less sure of it as a good introduction.

Computercraft turtles and LUA aren't terrible, but when I see a FOR loop I think C style, while LUAs is the other kind and I'd really love for that for to be named something like ITER instead.
Why are Pinduoduo and Alibaba selling fruits?
What an interesting article. I am now very curious to try the mother fruits pomelo and citron.

Based on the description here, grapefruits potentiate drugs by reducing the effects of a digestive system enzyme that would otherwise destroy much of the drug. Does this mean that it only has impact when drugs are taken orally?
Maybe a bit premature, but I'm glad this is going to Charpentier and Doudna rather than Zhang and the Broad.
