I get your point but equally the point of programming languages is to abstract away the harder stuff. The question is just how much abstraction developers want between the code and the execution. I mean, you could make the same claim about

In the instances you’ve described where “monopolies” haven’t dominated the market, they were not actually monopolies because they didn’t have total ownership of the market. A company can be a tech giant and still not be classed as a monop

For those that lived through the Windows 9x desktop monopoly in the 90s, the Internet Explorer monopoly, etc, they will see Microsoft as a prime example of how monopolies are terrible. In fact the few areas where you actually see Microsoft

That’s one option and it does make a lot of sense. Sadly free WiFi in the UK has largely been pretty awful. I’ve lost count of the number of times I’ve had a faster mobile connection than (for example) hotel WiFi. So I’ve just given up tryi

This then just pushes the layer of trust to the developers of the installers. The OPs point is, at some point in the chain you have to trust someone and in his opinion coffee shops are less likely to want to do bad things with your WiFi con

I did some quick research on the POSIX thing and it looks like cd (without parameters) is defined in POSIX: https://www.unix.com/man-page/posix/1posix/cd/ Also I don’t know why many of my posts keep gett

Technically the chances of tilde not working are the same as cd behaving differently because they’re both shell builtins. I’m guessing (though admittedly not checked) that both ~ and cd (without parameters) are defined in POSIX. In which ca

Ironically I find I spend less when shopping online too because I’m less likely to impulse buy stuff. Though I do often break the “don’t go shopping when you’re hungry” rule, which doesn’t help.

That’s an about page. If you go to the home page then you can see those words: http://learnthesewordsfirst.com/ The site isn’t the prettiest nor most logically laid out but the link to the words themselves was pretty clearl

I would be the outlier in that particular example but I think there is a fair amount in truth in what you said nonetheless.

As I said in my post, I normally pay £2. But the price is variable depending on time of day etc. I can’t recall what the minimum spend is but it’s way below our typical weekly spend anyway.

I think it’s more of an income thing than a location thing. Most supermarkets will have a minimum spend and then there is a delivery charge on top. Both are pretty cheap but if money is tight then that is one easy convenience to go without.

UK supermarkets have offered both a collection service as well as a delivery service for years. It’s great, you do your grocery shopping online and schedule a delivery or collection time and the supermarket does all the hard work for you. A

I don’t think anyone on here is in favour of bad people doing bad things. The general point is that when sanctions are used selectively on some regimes and the US buddy up with other regimes that follow the same kind of politics as the firs

Maybe but my experience on HN is that there’s sometimes a mentality of “fools never differ” on here. I’ve seen countless correct and/or experienced commenters get downvoted even when the comment is well written. It’s also worth remembe

It’s different because the DBI wouldn’t return an object for a nullable table record . Which is what we are specifically talking about. Sure other parts of your code might fail if you’re trying to use a scalar as an object (or such like) b

Right, but Perl 6 is also now a different language in its own right.

You’d also need to make magnets, know their polarisation, create bearings, and have the skill to assemble all of that as well.

I don’t disagree with you per se but wooden carts (with wooden wheels) has existed a long time before bicycles. Albeit such devices would be “powered” by animals rather than people. So the friction of baring-less wooden joints was probabl

Actually I said NULL isn’t an issue in some languages with looser type systems, not that other developers wouldn’t have encountered a NULL before. Eg Perl doesn’t have a nil type like Go, so variables passed to DBI which are NULL in the ret

Also VLANs can create a “multiverse” of IPv4 addresses behind a single NAT. But since VLANs are a layer 2 concept it means you can in theory use them with IPv6 as well (albeit I’ve never personally tested that theory)

I get Perl isn’t trendy these days but Perl actually has a very robust set of DB libraries and I have worked in several places were it was the preferred language.

Like everything, it depends on your language and framework. But after 30 years of experience writing software in strictly typed languages, I’ve seen lots of people get caught out with nullable fields. However if you’re main body of experien

Firstly, I’ve never said people shouldn’t have NULL. I said columns should default to be nullable. Secondly, I’d already given outer joins as an example of why SQL needs to support NULL. I would be nice that people like yourself bothered to

It is though I’d be more tempted to have that as it’s own table with more data attached such as the UID who deleted it, reason (if application supported that), etc. That way you can have more detail on “deleted” records without having to nu

I’ve had a great deal of experience with Go and there are many who’d argue that nil pointers in there is a mistake as well (though I’ve personally never had an issue - but I do write pretty robust tests too). I have ran into some instances
