Filed under: Gmail, Productivity, UI, User Interfaces, Web 2.0 — kenjun @ 8:11 am

Gmail uses Vi key combinations for certain email actions. For example, when looking at your Inbox (or any label or search result):

j – moves you up to the conversation above

k – moves you down to the conversation below

Other (none-Vi) key combinations are:

o – to open up an email

PAYE forms P45, P46 and P60

PAYE forms P45, P46 and P60

P45

The form P45 is a record of your pay and tax deductions. You’ll get it from your employer when you stop working for them. It shows details like:

  • your tax code, tax reference number and Tax Office
  • when you were last paid
  • your wages so far in the tax year (6 April to the following 5 April)
  • how much tax was deducted from your wages

A P45 has four parts. Your employer sends one part to the Tax Office and gives you the other three. When you start a new job, you give two parts to your new employer and keep the other one (called Part 1A) for your own records.

P46

If you’re starting your first job and don’t have a P45, your employer will give you a P46 to fill in and sign. HMRC will then process your P46 and issue your tax code.

P60

The form P60 is an annual summary of all your payslips. Your employer gives you one at the end of every tax year. You keep your P60 as a record of your pay and the tax that was deducted.

This site creates names for imaginary Web 2.0 companies – and guess what?

They’re pretty good!

Oil in the Oriente, Ecuador

Filed under: Chevron, Ecuador, Oil, Texaco, USA — kenjun @ 1:17 pm

Since oil was discovered in Ecuador’s Oriente in the 1960’s antiquated extraction practices have wreaked havoc on wilidlife and indigenous communities; the most contended case today is rainforest dwellers’ US $40-billion lawsuit against Chevron-Texaco for damages 30 times greater than those of the Exxon Valdez spill in Alaska. In the meantime, Ecuadorian government policy is trying to rein in foreign exploration, since 80% of oil profits leak abroad.

Some indigenous groups have formed agreements requiring all members to sign off on oil deals. One community traded land to an oil operation for a sustainable lodge that they now run themselves.

You Can’t Prove a Negative

Filed under: Uncategorized — kenjun @ 9:49 am

Hardly a mathematical statement but it can be a useful shortcut to explaining why an argument isn’t well-structured…

From ScepticWiki:

The claim “you can’t prove a negative” is often used as a shorthand in discussions to refer to the difficulty of gathering experimental evidence to “prove” that something does not exist. Proving that a phenomenon isn’t real takes a lot more time and effort than it takes to demonstrate it. This is especially true when the definition of the phenomenon can be changed at will by its believers.

In Law

In criminal law, the maxim of “You can’t prove a negative” is reflected in the “presumption of innocence”. That is, arguments of the form

You can’t prove that the defendant didn’t commit the crime.

are inadmissible.

Since it is perfectly possible to not-commit a crime and at the same time, have no evidence of that non-commission, the lack of proof does not imply anything.

Often, of course, one can prove that a defendant didn’t commit a crime, which again demonstrates that “You can’t prove a negative” is of limited value.

Other cases

It has been claimed that the United Nations demanded that Saddam Hussein prove the non-existence of weapons of mass-destruction under his control. This may be historically inaccurate, but had such a demand been made, it would have required evidence that every square inch of Iraq did not contain WMD.
