Slashdot Asks: What's In Your Home Datacenter?

Hypotensive Article fails to understand watts (283 comments)

This article would be a whole lot more impressive if the author actually knew what a watt was. The article repeatedly uses kW/hour even though this is not a measure. You either have a kilowatt (measure of power, or energy over time), or a kilowatt hour (amount of energy that running one kilowatt for an hour, or kilowatt MULTIPLIED BY hour, consumed).

Saying "average consumption is 1-2 kW/hour" is just nonsensical. If you mean that consumption is 1-2 kilowatt-hours, then over what time? Or more likely you just mean that average consumption is 1-2 kilowatts.

Ask Slashdot: Any Place For Liberal Arts Degrees In Tech?

Hypotensive Modern languages (391 comments)

Certainly if you are good at modern languages, tech companies are very interested in localization. It's unlikely you'll achieve a rockstar programmer wage, but you will definitely find stable employment if that's what you want.

Comcast Using JavaScript Injection To Serve Ads On Public Wi-Fi Hotspots

Hypotensive OK to continue (230 comments)

If browsers treated HTTP GET nowadays like they have treated HTTP POST (i.e. pop up an annoying modal dialog that says "This connection is untrusted. Are you sure you want to continue?"), I daresay this would motivate everyone to move to HTTPS.

The problem is the web of trust and the cost of getting certificates. There needs to be a mechanism for getting a free or trivial cost certificate if you are not a corporation.

The Technologies Changing What It Means To Be a Programmer

Hypotensive Re:Not changed much (294 comments)

If you go back 30 years you'd probably have had to write the language you were going to use and an interpreter or compiler for it. You would absolutely have had to know about the database design, although the database would have been made up of byzantine interrelated b-trees rather than intuitive SQL tables. You'd have had to write everything from scratch for each task rather than leveraging huge libraries for everything. Things are many times easier these days yet you still find articles like this that bemoan how complicated everything is.

Brookings Study Calls Solar, Wind Power the Most Expensive Fossil Alternatives

Hypotensive Comparison inherently bad (409 comments)

The paper does not distinguish between solar PV, solar thermal, and solar water heating, which are all completely different technologies with completely different scales of efficiency.

It does not distinguish between wind turbines sited on land and wind turbines sited at sea, despite the fact that the latter cost approximately 10 times more than the former to build and maintain.

Overall because of this conflation the results it comes up with are inherently flawed. Please try again.

City of London Police Take Down Proxy Service Over Piracy Concerns

Hypotensive Re:Not a private police force. (133 comments)

it's not private, not under the control of the companies in the CoL

The police authority for the City of London Police is the Common Council of the City, which is the Corporation of the City of London. According to the Police Reform and Social Responsibility Act 2011 there is no elected commissioner replacing that police authority.

In the rest of the UK police authorities were phased out in 2012 and replaced by Police and Crime Commissioners, however there were two police forces that were exempt from this, the Met (whose PCC is the Mayor of London) and the City of London Police whose authority remains with the Corporation.

It answers to the Corporation. You are right that UK taxes pay for it but it is far from being a publicly accountable police force.

City of London Police Take Down Proxy Service Over Piracy Concerns

Hypotensive Re:Not a private police force. (133 comments)

The Corporation of the City of London is a government entity (the government of the City of London) but it is not democratically elected (aldermen are "elected" in a closed system by companies not individuals and the Corporation can decide to revoke any such appointment for whatever reason it feels like). So effectively it is a private members' only club with its own police force.

The Problems With Drug Testing

Hypotensive Re:Huh (166 comments)

Unfortunately you do also need control subjects. Unless you compel people to do it (maybe at random, like jury service, or on other criteria, like conscription) you will always find exploitation.

Russian Government Edits Wikipedia On Flight MH17

Hypotensive Re:Let us keep our thoughts with our Kremlin frien (667 comments)

Ukraine's own military might have done it

This seems somewhat improbable considering that their enemy, the separatists, don't have any aircraft.

It's the same situation as you had in Syria where chemical weapons were being deployed by helicopter in barrels. Was it the rebels or the government? Well, considering that the rebels don't have any helicopters...

Unintended Consequences For Traffic Safety Feature

Hypotensive Re:Shared space (579 comments)

Having pedestrians wandering around on main arteries is not a good idea at the best of times. This is what pedestrian subways are for.

Unintended Consequences For Traffic Safety Feature

Hypotensive Shared space (579 comments)

A better solution might be to remove the signals altogether. Several European towns have tried shared-space experiments where there are no signals or markings and the pedestrians and vehicle drivers have to actually watch out for each other. In all such experiments so far, traffic fatalities have dropped significantly.

Teaching Creationism As Science Now Banned In Britain's Schools

Hypotensive Re:A minority view? (649 comments)

It's not a matter of evolution being true or not. Evolution is simply the scientific theory that explains the phenomena best, so far. There probably isn't any such thing as a universal truth, but it doesn't matter to science.

Creationism not only doesn't explain the phenomena best (since it fails Occam's Razor) but it doesn't follow scientific method and therefore is not a scientific theory. Therefore it cannot be taught as science, QED.

Also, there are lots of religious people that don't believe God created life, even Christians for whom the creation myth is a metaphor.

Google and Facebook Can Be Legally Intercepted, Says UK Spy Boss

Hypotensive "Google" not outside UK (104 comments)

However the Google pages that get returned by all UK ISPs are in the UK, because those ISPs use DNS hijacking to return their own servers' IP addresses (with a nice Google skin) whenever UK citizens ask for Google, and those servers are in the UK.

As to why they do it, something to do with complying with UK censorship legislation.

Britain Gets National .uk Web Address

Hypotensive Security issues (111 comments)

Since browsers now all support IRIs, this is likely going to be a big problem when someone registers something like gо or pо (note that 2nd letter in each case is not 'o' but CYRILLIC SMALL LETTER O: U+043E) and starts sending out "official" directives.

Life Sentences For Serious Cyberattacks Proposed In Britain

Hypotensive Re:Oi. The stupid. It hurts... (216 comments)

The killing people with a car touches a nerve.

In the UK you can just run over a pedestrian and kill them and it's treated much more leniently than armed robbery even if you killed nobody.

Now you'll get life imprisonment for hacking GreedCo's computer and showing that they paid the CEO more in a day than all the lowest ranked employees put together earned in a year.

Actual humans? Meh. But some fat cat's profits? They must be protected at all costs.
