Not quite the Bake Off they were expecting: Canadian seniors served weed-infused brownies

Sneaky edibles are not cool man.

Back in my heyday, before I poked golf ball sized holes in my lungs, I could (and occasionally did) rip through up to a 1/4 oz (7g) in a day, whilst remaining upright and mostly functional.

However, on the few occasions edibles were passed around, overindulgence invariably led to communion with Ralph. Southern Comfort mixed with scrumpy would be a pale comparison.

Re: Sounds a tad pointless?

Depends on what you want the acid to do. Good old sulphuric (or any other mineral) acid is pretty indiscriminate when it comes to attacking elements with essentially identical valency. (ie the entire lanthanide series) What this article seems to be saying is that the organic acids produced by these bacteria can reliably discriminate between different members of the series and do it with fewer toxic byproducts than existing refining methods.

Re: 6,681 qubits?

Problem is not that exceeding a certain number of bits might result in the system state collapsing in the real world. The real problem is that achieving a solution requires that the system collapses into one specific CORRECT state.

Inherent instability is the future of aircraft design.

Any further significant improvements in aircraft efficiency are almost certainly going to have to come at the expense of stability or they would have been implemented already.

Re: "US, Canada finally ground 737 Max jets..."

Standard software testing procedure (at least when I was in college) was to feed out of bounds data into a program and examine the results. We were also expected to consider how such data might arise in real world usage and code suitable error handling procedures. It's pretty damned clear that the systems in question were never properly subjected to GIGO testing.

No mission critical system should ever be released for production without it first being subjected to comprehensive tests intended to break it.

Nobody cares because CRIMINALS.

It seems to me that Congress-critters and their ilk don't see any problems with this sort of privacy violation because the only people it truly affects is miscreants and other never-do-wells. Joe Blakes like you and I have nothing to fear, because generally nobody has any reason to want to search us out in the first place.

That the occasional savvy stalker might abuse such a system seems to be the cracked egg price of facilitating "legitimate access" on the part of those who need it to do their jobs.

Mumsnet data leak: Moaning parents could see other users' privates after cloud migration

Re: not quite a financial institution or communications provider.

Credentials apparently weren't exposed, just the data protected by those credentials. So no actual passwords for reused elsewhere. Worst case is the exposed data that might be used to narrow the search space for possible credentials for testing against other login portals. ie. combining names/initials with birth-date/years.

Something I would really like to see is real world numbers on just how many average people are pwned through data breaches like this vs. top 100 password attacks on global user spaces. I strongly suspect that people who use even very simplistic password generation algorithms based on personal data/interests fare better than those who chose "clever" passwords like "drowssap".

Simple truth is that unless someone has a good reason to target you personally, any non-trivial password is probably good enough. A six letter word with personal significance + any two digits is likely to be enormously stronger than a 1337speak variation of "Millenium Falcon" despite the search space being potentially a few million times smaller.

Over the past few years we've seen a plethora of articles reporting on data breaches of so many millions of credentials, with the latest being some 700 million unique username/password credential pairs. So what does this really mean to the average person? The simple answer is, probably not a great deal, because unless you're Elon Musk or otherwise special in some specific way, you individually are not worth the effort of a targeted attack.

The website Have I Been Pwned is a semi useful tool for determining if somewhere there exists a site that you've provided credentials to has ever been breached, but I think it would be far more useful to be able to simply enter a password and be told if ten or ten thousand others have had the same idea, regardless of site.

Re: Greasy screen.

I find it annoying enough to keep the seven inch screen of the tablet I use primarily as an e-book reader clean. Just a few swipes is enough to put distracting rainbow streaks in the place my thumb "turns" the page. And a game or two of "Jewels" turns my screen into a reasonable facsimile of a petrol station forecourt after rain.

I hate to think how a 28" screen would look after a CAD/CAM session.

Re: Simulated crash

Because supercomputers can only carry out exact calculations on a limited number of particles. The same reason simulations of galactic collisions are modeled using only a few million stars instead of the hundreds of billions that real galaxies are actually made of.

Universe sandbox makes a lot of pre-programed assumptions that look good, but only bear a passing resemblance to reality.

Re: So does this also invalidate all facial recognition installed everywhere?

My take on this sort of technology is that it should be OK to use it to compare individual faces against a shortlist of suspect faces (ie known soccer hooligans) for targeted action (ie. prevent entry to a stadium), but not to compile a list of every attendee to be cross referenced with purchasers of road flares and vuvuzelas.

Re: Why not increase the platter size and/or the height of the enclosure?

Actually you can more than double the number of platters, because stacking two drives into a single enclosure eliminates the top of one case and bottom of the other.

I'm not sure that it's ever actually been implemented in a real world product, but dual (multiple?) sets of heads has certainly been talked about. One option here would be a single set of write heads combined with two or three sets of lighter weight read heads.

Black Betty

Re: Why not increase the platter size and/or the height of the enclosure?

I'm aware of the latency issues, but big drives are generally used for long term archival storage, which as a rule does not require rapid access times. For that purpose petabyte class solid state arrays exist.

My personal experience with Bigfoot drives is that they failed due to timing issues when the system bus speed was increased beyond 33 MHz.

Black Betty

Why not increase the platter size and/or the height of the enclosure?

What is so bloody special about the 3.5 inch 1/4 height form factor that manufacturers can't revert to 5.25 platters and/or taller enclosures?

An upset tummy and a sphincter-loosening blackout: Lunar spaceflight is all glamour

Re: Lunch from both ends?

Positioning was achieved with sticky tape and finger sheaths were provided to assist with "undocking".

Pragmatically speaking, assisting each other would make a lot more sense than backing up a couple of feet, since it would significantly reduce the chances of unintended "excursions". Any macho image preservation could have been done in post-production banter. Could not have been any worse than caring for an incontinent elder.

Re: Remeber those heady days of the Apollo missions well

Five year old me wanted to know what was in the hole* to one side of the moon's far side.

My grandfather (who built a TV** from scratch to watch the landing) carefully explained to me, with the aid of a bedside lamp and balls why part of the moon was in shadow.

At the end of the explanation, I collected my shovel and went outside to dig a shadow.

* There is indeed a dark side to the moon. It's what you get when there is neither sunlight, or Earthshine to illuminate the moon's far side.

CubeSat buddies, like those sent to track Mars InSight landing, can be used in future missions

Comsats for space missions.

Here's a thought. Devote at least one mission to nothing but establishing a permanent high bandwidth communications link between Mars and Earth. It's something that will be an absolute necessity if we ever do get around to sending manned mission, and in the meantime science orbiters and landers can work 24:37 without the need to take time out to laboriously transmit data back to earth at rates that would embarrass your average US telco.

With a near real-time link (latency 3 - 22 minutes) the possibility to react to and observe transient events would be greatly enhanced. Rover travel distances could be increased to kilometers per day. Without a need for a large antena and complex pointing system more space could be devoted to extra or more complex science packages.

In situ satellites would also make terminal guidance of approaching missions easier.

Strikes me that this is a security hole large enough to drive a super tanker through sideways.

When a client has no effective control over what data is sent to an off site server, they also have no control over who might ultimately view that data. What is to stop some rogue state (ie. my own bloody minded data slurping Australia) requiring document duplication?

Yes, you may use Office 365 offline, but from my reading, it appears that certain "features" kick in automatically/uncontrollably whenever an internet connection is present.

Secure alcove for bank ATMs

A bank here in Australia put some of it's ATMs (those in high street crime areas?) behind glass doors to prevent muggings of customers making late night withdrawals. In theory the customer was to swipe their bank issued keycard through a reader to open said doors before being able to access the hole in the wall machines. In practice, ANY card with a magstripe would cause the doors to open. Train ticket, hotel keycard, photocopier card, any card at all, didn't matter.

Result, nicely corralled victims with zero options for escape.

Let fines for poor security management equal absolute revenue.

Make it impossible for product vendors to boost/pad their bottom line by cutting corners on security, by fining them 100 percent of the revenues (not profits) from any offending products. Sell a millions crap devices for $10 each, pay a $10 million dollar fine on top of any reimbursement paid to customers for recalled/returned items.

Demonstrate a good faith effort to implement security, fine is not applicable, but crap like hard coded credentials, plain text comms, and other trivial security holes, should be matched be a black hole in the vendors wallet.

Re: Many values for true

Assembler library code is a likely culprit.

That or porting code from a language with strong data typing such as PASCAL in which booleans have exactly 2 values (TRUE and FALSE) to one that defines TRUE as any non-zero value.

Optimizing compilers (particularly early ones) can do strange and unanticipated things to code. Best practice is simply to never explicitly test for a TRUE condition.

The age of hard drives is over as Samsung cranks out consumer QLC SSDs

Black Betty

Maybe, maybe not.

First of all, pretty near all new systems are going to ship with a 250-500GB SSD, first in laptops and then soon after desktop systems too, because people just won't put up with sub-par performance once they've got a taste for the speed of an SSD.

Spinning rust will survive for a little while for media storage, and possibly ultra-high bandwidth applications.

But ultimately, I foresee some sort of ultra-high density write-once media being developed for long term archival storage.
