NSA Director Says Agency Shares Most, But Not All, Bugs It Finds

dhaen They needn't be lying (170 comments)

They probably pass on the chaff and keep the juicy ones. But let me ask you this: If you had their brief, would you do anything different?

World War II Tech eLoran Deployed As GPS Backup In the UK

dhaen Jamming (139 comments)

AC is correct. Jamming GPS (or equivalent other satellite system) is trivial and has been done. It's a major system weakness.

A decade ago I would have believed this as gospel, now I'm not sure. It's difficult to believe the US voice any more.

Microsoft Wants You To Trade Your MacBook Air In For a Surface Pro 3

dhaen Why just the MB Air? (365 comments)

If MS were serious they'd say ANY Apple laptop. After all, what are they going to do with the trade-ins, open a store? No, they'll destroy them.

Bitcoin Exchange Value Halves After Chinese Ban

dhaen Re:Comparison: Bitcoin is like 'Abortion' in the U (475 comments)

So China is banning the currency because it wants to protect the United States?

Not for that reason only, but China has massive investment in the US in the form of US debts. China wouldn't want anyone defaulting. Nor would they like seeing the US$ fall in value.

Ask Slashdot: Practical Bitrot Detection For Backups?

dhaen It's not bit-rot (321 comments)

If you're noticing data corruption on only 2TB it's probably not what we normally call bit-rot. A bit that changes state for no apparent reason within a very large set of data can be described as bit-rot, otherwise it's general data corruption which has many causes which all are understood: Poor media, poor transmission of data, overwriting of data etc. Once you've got the system sorted out so you don't get data corruption, start thinking about the nature of your data. How much redundancy is in it? If it's jpegs the almost none, so a single bit error could be serious to a file. If uncompressed TIFFs then there is a lot of data redundancy and the single bit error might only be an error of a single pixel, which you might not even notice. And finally, don't expect optical media to be safe from errors. Only use it as part of a DR plan.

A Plan To Fix Daylight Savings Time By Creating Two National Time Zones

dhaen Re:Daylight Saving Time (545 comments)

This whole clock switching thing is utter bollocks: First it was: "Our farmers need more daylight" - well just let them change THEIR hours! Next it was: "Our kids mustn't go to school in the dark" (but it's ok for them to come home in darkness) - - well just let them change THEIR hours! Next it was: "We'll save energy" - which is doubtful and unproven, but if you want to try - just change YOUR hours! There are only a given number of daylight hours in a day - you just can't have more! Since we all have biological clocks, it's difficult argue with the article that shifting hours screws with people's well being and efficiency.

Humans Choose Friends With Similar DNA

dhaen Culture matters as well (204 comments)

Amusingly I found that in Tokyo bars (in friendship terms) I had more in common with the locals than with caucasian Americans with whom I share the same European ancestry.

Nevertheless I am broadly drawn towards females who are similar to me. Those who look most dissimilar do not rate on my "wish to procreate with" list.

For the article's hypothesis to work, it's the second point that matters most. It means that the people who are born around you will be more like you and so are there for available friendship.

Not everyone is like me, and I'm glad of that. The more diverse the gene pool, the stronger the specie.

Cryptography experts meet inunction against publishing research

dhaen dhaen writes  |  about a year ago

dhaen (892570) writes "The Guardian runs a story that VW group who build Porches, Audis, Bentleys and Lamborghinis plus some lesser cars that ordinary mortals can afford, have banned publication of research that exposes security algorithms. It's becoming well known that security through obscurity is flawed and the Streisand Effect will now get to work"

Why speaking English can make you poor when you retire

dhaen dhaen writes  |  about 2 years ago

dhaen writes "BBC Business News reports that speaking English can significantly affect your savings philosophy. It seems that languages with strong future time reference (such as English) detach us from the future, thus making us care less about it. Languages with a weak future time reference (such as Mandarin) treat the present and future as being much more closely related, making people more likely to care and this save for it. The article goes further to suggest the degree we care about the future is language related."
