Linux Foundation says many Linux admins and engineers are certifiable

Paddy

No googling?

To some degree, it's not what you know, but what you can search for and apply. That what docs and google are for. If you are restricted in what data you can access then the certification is devoid from real life.

A lot of times I find problems are resolved by accurately noting symptoms and causes then searching for like problems and there solutions as well as being able to accurately convey to others the problem you have.

Such problem solving skills are a large part of what keeps systems up, as opposed to their initial setup.

Maybe you should not be allowed to ask a question on a support site for certification, but maybe you should be allowed to google?*

*Is "to google" generic yet ;-)

Puff on a hybrid – next thing you know, you're hooked on a public cloud

Paddy

Security? Licenses?

Does a public cloud have a solution to the issue of security? A companies secrets are protected to an obvious degree when using in-house servers.

Software licenses. Are they aware of the cloud. For example If I could purchase all-you-can-eat licenses for an office or a site, will it have to be re-negotiated for use on the cloud?

Open MPI hits milestone with FORTRAN-ready 1.7.4 release

Paddy

Fortran libraries resurrected.

Although I did learn Fortran two decades ago, if I had to use Fortran libraries today I would much rather access them from a Python wrapper i.e. Scipy: http://www.scipy.org/scipylib/faq.html#how-can-scipy-be-fast-if-it-is-written-in-an-interpreted-language-like-python

Ubuntu unleashes dual boot tool for Android mobes'n'slabs

Paddy

unleash the power of your portable network.

Hi. I have a Nexus 10 tablet in a case with a Bluetooth keyboard. Not only would I welcome proper Unix running on the tab, I would also welcome a capability to network my Nexus 5 phone and be able to run ipython notebooks on the network when travelling.

Tablets and phones have a lot of power. A more standard Linux would allow that power to be used for traditional work tasks.

The importance of complexity

Paddy

Enthusiastic self-taught programmer rather than a CS major.

I did Physical Electronics at University not CS, but programming and maths are hobbies and I have coded many CS algorithms and data-structures - Many for the Rosetta Code site: http://rosettacode.org/ - for use at home and at work.

Every once in a while I am aware that I am solving computationally intractable problems such as selecting the best N of M tests where N ~= 100 and M ~= 25,000 (I used a greedy algorithm: http://paddy3118.blogspot.co.uk/2013/05/greedy-ranking-algorithm-in-python.html)

Topological sorting is at the heart of arranging VHDL files and libraries for compilation: http://rosettacode.org/wiki/Topological_sort - I've considered implementing my own but the hard part is parsing the VHDL to extract the dependencies rather than the sorting.

So yes I do solve "algorithmic" and data-structure type problems, but the systems engineering problems are an important part of the whole too.

ARM 64 bit

Hats off to ARM for designing a 64 bit core that works in a phone. It's just that Ubuntu has the best plan to make use of it with their idea of a phone that when docked runs full Ubuntu Linux; hell, if Ubuntu was running on something like a Nexus 10 with a 64 bit ARM and 8 gigs or more of RAM ...

... I'd play Angry Birds on it!

Intel ships high-powered C++ compiler for native Android apps

Paddy
Meh

Re: Read the linked FAQ

So, it is indeed difficult to ascertain what processors the compiler works with.

I would have had to create an account to read anything from the link I did choose to follow so decided to ask, as I thought that it was info the article should have been clear on.

Oh well...

For intel chips only?

I can't work out from the article if the compiler will emit native Arm code or not?

Xerox admits there's no fix yet for number-fudging copiers

Paddy
WTF?

Another Y2K-like bug?

Is anyone looking at other brands of copiers? Just how widespread is the problem likely to be?

Should we all just confine purchases to those manufacturers that clearly state the have at least one mode that is guaranteed not to have a problem like this?

Apple at WWDC: Sleek new iOS, death of the big cats, pint-sized Mac Pro

Paddy
Childcatcher

It's Apple

Being forced to buy new kit to expand the new Pro should be expected. It is a fashion statement, you should expect them to pressure you to dump last seasons kit because it doesn't look fashionable - not because it isn't serviceable.

It may not be green, but its how they earn their greenbacks.

What Compsci textbooks don't tell you: Real world code sucks

Paddy

Identifiers should be succinct andNotTediouselyLongWinded. Presumably you are using a language with namespaces and so the enclosing namespace brings contect that need not be repeated in a choice of variable name.

On comments, I too hate _bad_ comments. Learn how to write good comments because sometimes they are necessary - for example, after you have got a good implementation that gives the right result, you may need to alter it for, for example, speed or memory optimizations. These optimizations may not allow the luxury of being in their own function and are going to be obtuse.

Menage á tablet: Apple vs Amazon vs Google

Paddy

7 inches is good, but 5.3 could be better

I do own the 7" Galaxy tab, but no smartphone. Given the cash I would buy the Galaxy Note phone and hope to retire the tab. I have large hands and like the feel of Note and the size of its display.

Python wraps its coils around the enterprise

Paddy

Re: When looking at a new language

What is a design pattern in one language becomes embedded in a more powerful language. Take using fict keys as a set: a design pattern once - now built in to the language . Take the decorate-sort-undecorate pattern, or the Schwartzian transform: that too is now built-in to the Python sort function.

Sometimes having a wealth of design patterns to learn just highlights the inadequaces of a language.

Re: The problem with Python

You are probably going about things in the wrong way if you advocate moving away from scripting as the problem gets huge or needs greater speed. Scripting languages like Ruby/Python/TCL allow you to get a working prototype out faster and give you something you can actually measure to find out where the problems lie.

Rather than a wholesale move to another language, scripting languages are built to interface with utilities written in other languages. If you know of a more performant tool for part of your task you have *measured* as being deficient in its script implementation then you could make another version that calls out to that library written in some other language. You can then test one version against the other for correctness as well as checking that you get your speed bump or whatever. Leave the scripting language in control of a larger application of many parts.

Re: Python talks to everything

"I'm curious. Just *when* did you try i++ and see it fail? As far as I'm aware, there simply has never been a version of C, even in Dennis Ritchie's imagination that didn't support this with exactly the same semantics as the modern language. "

Maybe the O.P. refers to all the undefined or hard to get right behaviour surrounding legal statements incorporating prefic & postfix incrementin; especially when coupled with assignment.

Swearing is OK though.

The BBC is doing such a good job on the web it has the paytards reeling. We should be encouraging the BBC to expand its commercial arm and so need less of a subsidy.

Authors lame flaim-bait

An informative article is spoilt with this:

"Those that consider GUIs bloat and think a good user experience involves green monospaced fonts on a pure black terminal window will not be pleased with the new Ubuntu. Unfortunately, from the looks of things, you are Ubuntu's past. The real world of everyday, dare I say ordinary, computer users are Ubuntu's future."

You do know that people can use console interfaces as well as GUI's.

If it doesn't skim then reject

I often skim text and try *not* to give the benefit of doubt to the authos of 'scholarly papers'. If it doesn't skim, then I more often find, that on closer examination, the author isn't trying to be clear.

(It's not only Wikipedia tha may contain crap).

Brighton professor bans Google

Paddy
Unhappy

Back to the dark ages?

I wonder if the professor would prefer all bibles to be in Latin too?

Gleaning data from books is a skill that has to be learned. Gleaning facts from the internet is a different skill that also needs to be learned. The professor is right to mark down students who don't use the internet well but forcing them to not use the internet is a cop-out. Teach them how to use the internet well, or if you don't know how, get someone who does!

There are a lot of bad books, as well as bad web pages. If a student contributed to a factual web page they would get some idea of how inaccuracies appear and can be fixed (or not), bias, ...

Update your teaching rather than appearing as a Luddite.

Code scavenging goes formal

Paddy
Go

Cookbook, CPAN anyone?

It seems to me that scripting languages such as Perl and Python have recognised the benefits of code reuse and their communities have spent time putting together code repositories such as http://www.cpan.org/ and http://aspn.activestate.com/ASPN/Python/Cookbook/ . Searching can still be a pain but people do explain their problem, together with their efforts so far, on newsgroups such as comp.lang.python and receive community help as either original code snippets, or pointers to code .

The process can always be improved, but at least with open-source scripting languages such as Python and Perl, you're not starting from scratch.
