Briny liquid may be more common on Mars than once thought, unlikely to support life as we know it

Life is more tenacious than you would expect

There are very few places on earth where life hasn't arrived.

Selection happens when there is pressure to survive so there is no reason why anything on earth would evolve to live in an environment which doesn't exist on earth.

Without looking into Scientific papers you can get an idea at

As coronavirus catches tech CEOs with their pants down, IBM's Ginni Rometty warns of IT's new role post-pandemic

Paul Johnston

Here is my guess

>>I'm going to modernise applications that my IT [department] perhaps weren't modern enough to change fast enough for me'.

So they will ask all the IT senior managers who will say "Oh not our fault look at our ancient staff, they are not agile enough".

Redundancies hit at the lower technical levels as we don't need them, only people who can manage a "Digital Transformation" will remain.

It all goes pear shaped. Senior IT management move on to their next positions and organisations are left with partially working systems (if they are lucky) and no one who can sort it.

As I say just a guess.

Python 2 bows out after epic transition. And there was much applause because you've all moved to version 3, right? Uh, right?

Paul Johnston

Re: why python ?

Critical mass is one of the main reasons I would say.

As more people use it and the library support grows you have to move with the times for better or worse.

For example if you want to use pymol you need python, end of story really.

WSL1 versus WSL2

Anyone seriously had a look at WSL 2 recently.

I've been looking to see if it can replace having dual boot machines with Ubuntu 18_04 LTS and Win 10.

We have to run OpenFoam and it requires the sort of grunt Virtual Box is going to have issues with.

Also supporting Linux for people who have never heard of it but who need to use it for their PhDs is to say the least not fun.

So I have it installed and some simple benchmarks for simple file operations suggest WSL 2 is noticeably slower than WSL 1.

The curious case of a WordPress plugin, a rival site spammed with traffic, a war of words, and legal threats

Recursion is difficult

I once advised a Professor that rather than staying with his very old Sparc box running Solaris under x86 was a better idea.

He bought a new machine and was not very happy as he said it was far slower than his old machine.

I said I couldn't see why but he was the respected professor of computer science.

A couple of days later he admitted there was an infinite loop in his Prolog code and once this was sorted it really was very fast.

Word boffins back Rimini Street in Oracle row: 'Full' in 'full costs' is a 'delexicalised adjective'

Paul Johnston
Holmes

The bit that interests me is using "corpus linguistics"

Corpus Linguists tend to work in statistics rather than absolute rules and judgements.

So although they would say x is a delexicalised adjective it would often be governed by something like "97% of the times in 2000 occurrences based on a corpus of size 5000000 tokens taken from the specific domain of texts of legal representations in the USA"

Corpus linguistics is based on actual usage rather than abstract rules.

Domain of the corpus is core to this idea, the classic case is the difference in the use of adjectives to describe legal and non-legal drugs.

GCSE computer science should be exam only, says Ofqual

GCSE Computer Science

Perhaps you might want to look at what is actually in GCSE OCR Computer Science

I've got in front of me "The Revision Guide" and "Exam Practice Workbook" for my daughter who is taking it this year and it's not just about coding.

Sections on Components, Networks, Issues, Algorithms, Programming, Design Testing and IDEs and finally Data Representation.

One questions asks about 4 conditions from the Creative Commons license. FFS!

If you think the problem is schools IT kit think about Edsger Dijkstra and his "Computer science is no more about computers than astronomy is about telescopes" (okay I know it may not have been his quote) but you get the idea.

Break out the jelly and ice cream! Microsoft's Small Basic turns 10

Paul Johnston

Funny this came up

Over the last couple of weeks I've been visiting schools in Tameside (by son is going to senior school next year). He is keen on computers so visited the ICT departments and most talked about Scratch and python.

All except one which said they use Small Basic. Didn't think much of it until I saw this so it is being used somewhere. Not saying it's good of bad but looking at the GCSE Computer Science syllabus the actual language they learn to program in is fairly irrelevant.

Example question Identify three benefits of using layers when working with network protocols :-)

Linguists, update your resumes because Baidu thinks it has cracked fast AI translation

Paul Johnston

Re: Missing a Bit

On page 6 of the paper I put a link to it talks about this.

If you have a series of matched translations and the Russian ones generally have fewer words than the English ones which contains "is" the model "realises" in the Russian copular is implied and so deasl with it.

The same goes for definite and indefinite articles.

Clever eh!

Insert AI for added interest

I fail to see this is any advance in Kevin Knight's paper from 1999

http://mt-archive.info/JHU-1999-AlOnaizan.pdf

With enough training data you get a better idea of what word follows another or group of others.

The fun comes with languages with relatively free word order i.e. where subject and objects carry case markers rather than by their position e.g. ones with lots of morphology.

The bit I found interesting

Reading the report one of the problems was the mailing lists of Sys Admins was out of date so when they e-mailed people to warn them of the vulnerability not everyone got it. I thought if you looked after something part of the job was to keep any eye out for announcements for said systems and if necessary pass that information upwards. I understand you cannot go patching stuff as and when you feel like it but at least try and keep them safe! Oh what do I know?

Re: Urdu?

Short answer the way they are written, Hindi in an "Indian" script, Urdu in a "Perso-Arabic" script.

Long contentious argument Hindi is spoken by Indians, Urdu by Pakistanis so they must be totally different. Think Kurdish v Turkish where both sides have nuclear weapons hence icon.

Interestingly all the languages mentioned are classed as Indo-European so theoretically from similar roots.

Encryption

As to encrypting the disk or more specifically the home directories we only do this on laptops, being mandated by our security policy. Since a lot of the installs I do are dual boot it makes access between the windows and linux partitions a lot harder but policy is policy.

Re: Computerised medical devices need TWO computers

Couldn't agree more with your solution.

Just had to scan a SCSI disk from a Scanning Electron Microscope whose controlling PC was running Windows 2000. Even better when the machine has PS2 connectors for keyboard and mouse.

As soon as the PC goes so does the microscope!

Once again we get the "oh that sounds too complicated" comment when we ask to do it and the using DVD burners has it's whole range of issues. :-)

Re: Not just open sea navigation...

It's quite hard to do damage in a situation like this by just changing the vessels direction. The only way I could see to close the canal for more than a very short period of time would be to scuttle it in a way it was hard to refloat and that's quite hard. You would have to rip out a large section and as the Suez canal isn't hard lined, well it wasn't the last tome I went through it. You really need to look at taking out the locks on something to create long term damage. So if you see a vessel called HMS Campbeltown that's the time to worry!

HPE donates 3 mini-supercomputers to UK universities boning up on Arm

Paul Johnston

The interesting question is did they ask anyone who said no thanks!

In the increasingly commercial world of IT provision at Universities I can see people saying no thanks.

Rackspace and power costs both running and cooling have to be recouped somehow. The people who can pay for this stuff in Universities tend to be those running Engineering (CFD and structural analysis) and Life Sciences (sequencing data). They are the ones who get big grants which need big iron to do their work. This looks "blues skies" rather than "must have" stuff hence them "giving it away". I understand Edinburgh as it's a computing research centre but as part of a general HPC system for non Comp-Sci groups not sure how useful it would be. YMMV!

Water and Electricity (see Icon)

Got a phone call from a user saying the monitor had started developing strange colours at the edges. The cluster had CRTs and they were getting on so I said guess it is failing and if they had a problem just move to another and we would replace it. Then they volunteered that it was making a crackling noise. My response was to just move away to another and I'd pop up to the top floor where it was. Then I get that bit where the user thinks they can diagnose the cause of the problem. Could it be the water dripping from the ceiling onto the monitor causing the problem? I possibly swore, I cannot remember, something like please just get the F* out of there and touch nothing. Safe to say a flat roof in Manchester was never a good idea.
