Steve Ballmer's Big-Time Error: Not Resigning Years Ago

A Pressbutton the trouble is that they keep changing the UI and (357 comments)

back when it was win 95 or NT, the was no large established ecosystem that relied on a API and any changes to the UI were clearly better. 20 years later there are billions of users all dreading the thought of something different - and win 7 counts as different. there are hundreds of thousands of developers all thinking the same. your customers don't want change - but you only make money if you change. the only thing stopping MS becoming altavista is that MS enables so many critical businesses processes using VBA and until processes change, that won't change.

actually, in the UK, the pensions regulator has very extensive powers to do just about anything that protects the pension fund. this includes preventing mergers, going after foreign parent companies after they have sold the subsidiary, and the directors. sounds draconian but it is there to protect your 80 yo grannies pension - otherwise you would have to look after her

Concern Mounts Over Self-Driving Cars Taking Away Freedom

- they will be networked, this will make them safer in normal use and you should get there faster
however that will provide the average prankster endless fun rerouting you or causing jams
- if some cars are manually driven, you will be able to drive them in such a way that makes an automatic car misbehave (stop) ignoring the safety bit here

Spreadsheet Blamed For UK Rail Bid Fiasco

A Pressbutton Its all about the process dummy. (125 comments)

The calculation could have been done on paper / blood on a wall / notches on a stick
carried out by throwing dice / abacus / mental arithmetic
morons / normal people / genii
If the process was not validated and the results were not checked, why is anyone surprised when it is wrong?
Some areas can be defined as right or wrong by people with good minds and strong opinions - games
Tax and Financial software not so.
At some point in the process $product needs to be validated using $external_process by $people_who_should_know
I am betting this did not happen.

New Analyst Report Calls Agile a Scam, Says It's An Easy Out For Lazy Devs

A Pressbutton use the right tool (491 comments)

This is the same sort of discussion you get with c++ vs php - the question is what is the job.
basically it should be clear to all that if you design,code,test,doc,release,stop - that is the most efficient approach. say this takes an effort size 1
the trouble is that what is released is probably not what is wanted.

under agile effectively you take a small part of the job and design,code,test,doc,release,stop let the customer loose and then repeat.
repeating this process n times for each 1/n th of the project takes more than effort size 1 as even if you never even look at any part of the code previously written, the tests you are adding and running will - and the whole point of agile is that you iterate toward the true requirement so you will be re-working.
the trouble is that what is released at the end will cost more.

please flame me for stating the obvious, but if you know what you are doing, and what is needed you should use something like waterfall and if you do not know what you are doing/is needed, use agile

Whatever Happened To Programming?

A Pressbutton Every Programmer Uses Libraries (623 comments)

Use Qt/ Win32/ Perl/ VB/ GCC - well just about anything You are using libraries written by someone else. For Perl it is called CPAN and is an advertised strength. The only person who arguably does not use a third party library is someone who programs FGPA arrays without a macro assembler. Engineers do not make their own screws and screwdrivers anymore, and whilst it may well be interesting to do so, the industrial revolution tells us that there are better things to do with our time. The points made on trying to make integration easier are useful.

When Will AI Surpass Human Intelligence?

A Pressbutton We might get to mouse-level in 20y... (979 comments)

No-one knows what intelligence is. If we did, some smart person would have done it by now.
We are not really making much progress towards answering what consciousness is.
This could be because there simply are not the words to define what we are talking about.
After all and with many apologies to Neitzsche 'Whereof one cannot speak, thereof one must stay codeless'
The best promise / progress I have seen is the brute-force reverse engineering of some brain functions. You do not need to analyse or understand, just copy.
This includes PET scanning of humans in a vegetative state, Seeing what a cat sees through the implantation of electrodes.
I think I read some researcher is just about able to simulate an ant brain with reasonable fidelity.
Simulating a human brain or equivalent will also imply the ability to receive / simulate and process all the inputs and outputs to and from the brain - i.e. you need the body. This is a big job.
Before we get too eager or depressed, remember that people were making experiments on birds - trying to reverse engineer them - for some hundreds of years (Da Vinchi) before we managed to make powered flight work.
One problem for the AI people is that once they solve a problem to any extent, it is not AI anymore! - remember context sensitive help and text recognition used to be part of AI.

Video Review of Hivision's $100 ARM-Based Android Laptop

A Pressbutton No need for a conspiracy (220 comments)

Netbook makers will maximise their profits.
If this is through selling windows / intel they will do just that.
I personally think wintel came along with appropriate inducements.
I also think that they asked themselves - does it play BB Iplayer HD / Youtube HD without stuttering at that price - and decided to come back when it does.
No point in a 100usd device if it does not work (whatever you define work to mean).
In the UK, if something like this does not work with Iplayer, it will be thought to be broken (ipad).

So this is the last Groklaw article. I won't turn on comments. Thank you for all you've done. I will never forget you and our work together. I hope you'll remember me too. I'm sorry I can't overcome these feelings, but I yam what I yam, and I tried, but I can't.
This is in response to the ongoing Snowden debacle. Please go to groklaw and read the full article. Her response to the 'if you have nothing to hide...' argument is ' I don't like uninvited strangers looking through my stuff' and that not being watched is a key human freedom.
I would add, if you are a us taxpayer, you are paying for this. A sad day."

Japanese physicist finds reality is real

A Pressbutton A Pressbutton writes  |  more than 5 years ago

A Pressbutton (252219) writes "In the 90s a physicist called Lucien Hardy devised a thought experiment where a particle and anti-particle could interact, but not be destroyed, as long as they were not observed.
Last week The Economist reported that a Japanese team has published a paper in the New Journal of Physics that claims to prove the paradox.
The abstract follows

Abstract. We implemented a joint weak measurement of the trajectories of
two photons in a photonic version of Hardy's experiment. The joint weak measurement has been performed via an entangled meter state in polarization degrees of freedom of the two photons. Unlike Hardy's original argument in which the contradiction is inferred by retrodiction, our experiment reveals its paradoxical nature as preposterous values actually read out from the meter. Such a direct observation of a paradox gives us new insights into the spooky action of quantum mechanics.

Basically things do happen when no-one is looking. We now know that is a tree falls and no-one is in the wood, it does make a sound.
I have not read many papers, but managed to pore through this one — it is quite readable. The Economist (and other sites) mention that some observations indicated that there were negative numbers of photons observed. I think they gathered the point from this comment on page 7 — perhaps overstating what the paper says.

Then, in Hardy's set-up, the same measurement presents a contradictory statement in figure 4 that the probability of finding a photon in arm O1 approaches 1 and so does the
probability for arm O2, whereas the joint probability of photons being in both of the arms stays
at about 0. Moreover, the readout points to a negative value for the joint probability for arms NO1 and NO2. Unlike Hardy's original argument, our demonstration reveals the paradox by observation rather than inference.
