Re: Liability ?

Nah, they don't count. Using a computer, see. Totally different!

Advertisements in newspapers that might otherwise be mistaken for editorial content are required to carry the words "ADVERTISEMENT FEATURE", in a font no smaller than the advertisement text. But on the Internet, there is no requirement to mark out advertisements from editorial -- and some Internet companies appear to be actively frustrating attempts to detect unwanted content. Which is not illegal, because it's not a printed publication and therefore not the same thing.

An app store isn't selling you a product; it's selling you a licence to use a product in certain ways and subject to certain conditions. And being completely different from an actual bricks and mortar store that sells product, they have absolutely no duty of care to you. Because everything is completely different if a computer is involved, and altogether different again if the "computer" happens to be pocket-sized. </sarchasm>

What about ad-blocking at the ISP level?

For some time now, I have been wondering about the viability of setting up a premium ISP business with "transparent" ad-blocking, including half-proxying i.e. fetching the file but never actually delivering it to the browser. Basically I think I'd just need a simple Linux server with some customised Bind zonefiles, and some broadband to re-sell.

I'm sure people would pay extra for no advertisements.

Re: Header pic

The idea of an earthed metal enclosure is, if a live wire comes adrift inside the appliance and then touches the metal case, the fuse will blow.

If you insert a Schuko (earth connection by means of contacts at the edge of the plug) or French / Czech (earth connection by means of a pin protruding from the socket) plug into a non-earthed socket, the metal case of the appliance will not be earthed. Now if a live wire comes adrift inside the appliance and touches the metal case, it will become live.

An RCD measures the difference between current flowing out the line and returning up the neutral -- which should be equal. If they are different, either Kirchoff was mistaken (which is actually not impossible, since verifying either of Kirchoff's Laws or Ohm's Law requires the use of test instruments which rely for their operation on those laws being true in the first place) or some electrons have unilaterally decided to take a different route back to the supply, possibly via you. So the RCD disconnects the supply.

Either a fuse or an RCD will offer protection against a live wire touching an earthed metal housing. (Other faults are available.)

Re: Header pic

The adaptors that you can buy on the High Street for a couple of quid don't usually have the earth contacts at the edges for Schuko plugs. They will accept the line and neutral pins of the plug, but leave the appliance dangerously un-earthed.

(Earthing might be less important if you have an RCD-protected supply, but I still trust a wire fuse more than I trust a chunk of complicated electronics.)

Re: Header pic

My school had a chemistry teacher who used to play a trick on next year's intake, visiting from their primary schools. He would place a beaker of concentrated ammonia and a beaker of concentrated hydrochloric acid in each of a pair of old boots; place the boots next to each other behind the front desk, resulting in a nice plume of "smoke" where the two invisible vapours reacted; and strew some broken glass around. Thus creating an illusion of somebody having blown themselves to bits, leaving only the canonical pair of smouldering boots. Then he would hide in the prep room, and watch the looks on the little darlings' faces .....

Toilet Seats

All I want from the toilet seat of tomorrow is improved thermal properties; a low thermal conductivity and a low heat capacity.

Picture the scene. It's a cold Winter's day, and I've been trying to put business off as long as possible; but now there is no way to continue to pretend the situation is anything shy of urgent. Unfortunately, by this time, the quantity involved is now greater than can be disposed of in the time for which my leg muscles can reliably maintain me in a "hover"; thus requiring actual bum-to-seat contact.

Re: Great system...

It's probably going to read /etc/myprog/config first, then ~/.config/myprog/config , and ignore the living daylights out of /usr/share/myprog/default/config .

The canonical order is supposed to be to read configuration from /etc/ first, and then from somewhere under the owner's /home/ folder; that way, users' own options override system-wide ones. (But there are always a few exceptions .....) /usr/share/ is not for loading configuration files from; any "configuration file" you find under there should be just an example.

But if in doubt, read the Source Code.

Spoons

In my workplace kitchen, there are many "tea" spoons, yet only one of them has a sufficiently stiff handle to withstand actually squeezing a teabag. The others are fine for stirring and measuring, but their handles have the consistency of solder.

Every time I come to make a cup of tea, the decent teabag squeezing spoon is invariably covered in horrible sticky brown blobs of coffee. (I sometimes drink coffee, but I have never managed to make such a mess of the spoon.) And when I place clean, dry spoons in the coffee and sugar canisters, for the purpose of measuring out ingredients without cross-contamination, somebody seems to think they were put there so they could take the spoon out and use it to stir their coffee.

Every. Single. Sodding. Time.

The only thing keeping me from sending an e-mail to all staff is the thought that I will be the one who gets called the whiny b***h.

Nobody Reads Error Messages

The problem with users is, they don't read error messages. Or if they are reading them, they are not paying any mind to them. Also, they somehow expect you to know exactly what is going on, even when you are on the other end of a phone line in a different room.

On several occasions I have asked a user to read an error message to me down the phone, read it back to them verbatim, and then they understood it.

Them: It says Username or Password Incorrect.

Me: Username or password incorrect? That means you've typed either your username or password incorrectly.

Them: Alright, I'll try again ..... Oh, it worked that time!

Me: All sorted then?

Them: Yes, thanks.

Or:

Them: It says Load Paper in Tray 1.

Me: Load Paper in Tray 1. That means it wants you to load some paper into tray 1. Is there any paper in tray 1? That's the top one, with a big figure "1" on it. Pull it gently towards you.

Them: I'll go and check (retreating footsteps, pause, approaching footsteps) No, there's no paper!

Me: Ah. OK. Try putting some paper in it.

Them: OK ..... (retreating footsteps, pause, approaching footsteps) The message went away as soon as I closed it, and it's printing!

Me: All sorted then?

Them: Yes! I fixed it all by myself!

Me: At least you know how to deal with Load Pa ..... (dial tone)

Then there are all the weird faults where the error message has disappeared before the user gets a chance to read it; but when you go and stand right next to them hoping to reproduce the error, everything mysteriously Just Works First Time. And that only seems to convince the users that "computers daren't misbehave when she's around".

Re: Itchy Chin

Re: Itchy Chin

In a loosely typed language (like JS, PHP, etc...) how does the computer know if the programmer wants to concatenate of sum two values?
Easy ..... If you use an addition operator between the operands, it should try to add their numeric manifestations; but if you use a concatenation operator, it should try to concatenate their string manifestations.

JulieM Silver badge

Re: Better One Innit

Yes, but a standard 20 or 25cm. slide rule is only accurate to three figures, which cancels out the error.

JulieM Silver badge

Re: Itchy Chin

That still need not be a problem, though:

  • If the programmer is asking the computer to add strings, then treat them like numbers (and either throw an error if they don't look sufficiently numeric, or evaluate as much as you can in a numeric context and silently ignore the rest) and add them.
  • If the programmer is asking the computer to concatenate numbers, treat them like strings and concatenate them.

JulieM Silver badge

Re: Itchy Chin

But strings and numbers are not necessarily incompatible types. You can always convert a number to a string in order to concatenate it with another string, and you can sometimes convert a string to a number -- depending what characters it contains -- in order to add it to a number. There is no reason, besides mean-spiritedness on the part of the programming language designer, for any modern programming language not to do type conversion automatically if it would not cause an error.

The real problem is the misuse of a single operator to perform two distinct operations.

JulieM Silver badge

Re: Itchy Chin

It's not perfectly reasonable because an interpreted language should be smart enough to be able to convert a string that looks sufficiently like a number to a number and then add it to a number; or convert a number to a string and then concatenate it with a string. Perl manages all this just fine (see examples above).

If you can find a book of four-figure mathematical tables somewhere, and someone who still knows how to use them, try to multiply 2 * 2 using logs.

Re: Itchy Chin

And why do you suppose someone would prefix the year (which, coming from a Unix timestamp, has had 1900 subtracted from it) with "19" -- which was bound to break come the year 2000 -- as opposed to the obvious and future-proof method of just adding 1900 to it? Might this possibly have had anything to do with the relative difficulty of adding numbers versus concatenating strings?

Re: Itchy Chin

Not as well as some languages, it doesn't:

$ perl -e 'print 2 + 2;print "\n";' # prints 4

$ php -r 'print 2 + 2;print "\n";' # prints 4

$ perl -e 'print 2 + "2";print "\n";' # prints 4

$ php -r 'print 2 + "2";print "\n";' # prints 4

$ perl -e 'print "2" + 2;print "\n";' # prints 4

$ php -r 'print "2" + 2;print "\n";' # prints 4

$ perl -e 'print "2" + "2";print "\n";' # prints 4

$ php -r 'print "2" + "2";print "\n";' # prints 4

Itchy Chin

I have a very hard time believing that JavaScript evaluated 2+2 as 4, and not 22.

JavaScript can subtract, multiply and divide, but the + operator performs string concatenation. If you want to add numbers, you have to negate and subtract instead.

Maybe copyright itself is an idea whose time has been and gone?

Back In The Day, copyright was invented as a way to encourage the creation of material to enrich the Public Domain. Authors were given temporary exclusive control over their work in return for a promise eventually to share it with everyone after the expiry of the exclusive period.

Changes in the meantime have affected the practical difficulty of becoming a publisher.

Is it really too much to suppose that there might actually be another way of rewarding people for sharing their works, besides through a temporary monopoly, that might be more appropriate to today's world?
