Telstra drops nbn™ in it as it wears compo for broadband speed ads

aberglas

60 Concurrent Televisions from 100mhz

Amazing technology, FTTH. 60 televisions each showing a different show. Wow.

Trouble is, most households do not have 60 televisions. Indeed very few have more than 6. So unless you are running a data center, these high speeds are just not useful.

The problem was never bandwidth. The problem was availability. To people that did not already have good ADSL or cable. That should have been the original focus, people without decent broadband in the first place.

But instead, the NBN has mainly been built out to people that were already happy with existing service. Hence the complaints about having to cut the copper. And many households will end up just moving to mobile.

The whole NBN fiasco was based on the premise that people wanted very high bandwidths. And that premise is wrong. Once people can run two or three TVs they have enough bandwidth. You do not need 100mb to run Facebook.

Incidentally, few providers provide less than 25mhz, and there is very little price difference for those that do. If 12.5 mhz was offered at 60% of the 25mhz price, it would be the most popular. Heck, if 6mhz was offered at 60% of the 25mhz price it would be the most popular for households without teenage kids.

Like Uber, for socialism: Chinese leader calls for more use of AI, big data and sharing economy

China is frightening

Have a look at Document 9's "Seven note worthy problems."

https://en.wikipedia.org/wiki/Document_Number_Nine

And they actually said this. Not just did it.

Their upcoming use of AI to control people will be truly Orwellian.

AMD comes out swinging, says: We're the Buster Douglas of the tech industry!

aberglas

SGX -- More than speed

It is tough being in a market that you only compete on price/performance. So Intel is trying to add features. One is SGX, which enables code to run in "enclaves" that cannot be accessed by the O/S or anything else. A bit spooky, but novel and riddled with patents.

If you have an application that relies on SGX, you will not go AMD even if it is faster and cheaper.

Java EE 8 takes final bow under Oracle's wing: Here's what's new

aberglas

Java is still big

(Probably way too big.)

The only comparable technology is .Net, which is fine if you want to confine yourself to Windows.

The various scripting languages do not come close. No static typing makes them horrible to work with in large projects and their performance is inheritantly bad (even with the new run times that do brilliant job of optimizing a broken design).

C/C++ are archaic rubbish that should never have become popular and cost the world billions in wasted programmer productivity. Go etc. do not have the JIT compilers and generational garbage collectors.

So Java is a bit of a monster. But it works. And it works well.

(J2EE is another story. But it can be safely ignored.)

nbn™ sweetens the deal for business and its own bottom line

aberglas

Businesses do not spend much time on Netflix

Most businesses have minimal need for video. The occasional webinar etc.

So they actually have less bandwidth demand than home users with teenage kids.

It takes very little to power the web. Even most cloud servers can chug along in the background without much bandwidth.

French car maintenance is great

Everybody knows how horrible they are, so I can pick up a low km Citroen for about half the cost of the equivalent Toyota. When it goes bang, throw it out. (My current C4 requires major work just to change the air filter which is stuffed *behind* the engine.)

Pity this does not work for phones.

Australia reviews defence export controls, perhaps easing cryptography research

aberglas

Not really enforceable

Fortunately, Australia is not the USA. So people here are not sentenced to long prison terms for technical breaches. Particularly that every laptop that travels is full of crypto.

But those regulations are a nuisence. They could hold up government contracts etc. So good to see them go.

Now only one version of Excel per (virtual) machine. Unlike previous versions. And no install options.

There are lots of bugs and limitations that go back to Excel 1995 that have never been fixed, and will never be fixed.

Australian telcos promise to be better NBN helpers

aberglas

It is not the copper wiring

The article is talking about the problems with backhaul. The last mile works fine for most people. But there is no point if the telcos do not provide sufficient capacity at the other end of the wire. And the NBN charges the telcos for the privilege of providing backhaul, which is why they are not doing it.

Leave the "fraudband" politics behind and stick to the facts.

German court reveals reason for Europe-wide patent system freeze

aberglas

Software Patents

The problem with any unified patent court is that it will become part of the patent industry. And thus strongly inclined to widen the scope of patentability. That is what happened in the US.

Currently, the law states strongly that software "as such" is not patentable. The EPO interprets that to mean "unless it runs on a computer"(!), and thus grants lots of patents, which are probably not enforceable by any normal national court. But a unified patent court controlled by the EPO would almost certainly decide that software is in fact patentable.

The fight against European software patents has been long and ongoing. Do you really want to follow the Americans there?

TechnologyOne says City of Brisbane ignored its own reviews

How do small councils survive?

Brisbane City Council is several times bigger than smaller regional ones. Yet they both do the same sorts of things and need the same sort of IT support. Rates, dog licenses, capital works projects etc.

And a Rates system that does 1,000,000 residents is no more complex than on that does 10,000 residents so there is a huge economy of scale.

And yet, rates for Brisbane are quite high. And the smaller councils still manage to get things done.

One of the mysteries...

AI bots will kill us all! Or at least may seriously inconvenience humans

aberglas

But does it matter?

Obviously, really intelligent machines will never be built because they have not been built yet. Nor are they likely to be built within the next few decades.

But once they are built, the ones that survive will be good at surviving. Natural selection. And being friendly to parasitic humans is not likely to help them survive in a competitive environment. So meat based intelligence will become obsolete.

But does that matter? As individuals, we will all soon grow old and die anyway. What are our descendants? Men or machines? Is this how "we" achieve immortality?

It actually does not matter whether it matters. It is inevitable anyway.

The hidden horse power driving Machine Learning models

aberglas

Machine Learning <> (!= for some) Artificial Neural Networks

There are many types of machine learning. ARNs have the buzz at the moment, and are often used inappropriately. And even if ARNs are used, there is (much) more to them than the naive back propagation algorithm that is so, so slow to learn.

Fix the algorithm before going crazy with hardware.

Revolt in China!

Nonsense about there never being a revolt there. Taiping was home grown, as was Boxer and Sun. Heck, Mao's crusade was a revolt. Read your history, China has been nothing but revolts until recent times.

However, Goulash communism requires the standard of living to rise every year so that people will put up with the government. China simply cannot keep growing at the astonishing rate it has for too much longer. There will be stagnation, and people will blame the government.

This could lead to horrendous trouble. At the moment the Chinese government is fairly benign because there are no threats. But if there is a real demand for democracy, will they adopt it (probably in a Russian style) or stand firm and fight.

Either way, it is very important to keep trouble makers on a tight leash. New AI technology for monitoring communications can help a lot with this.

The real thing that the UK could learn from China is the way their bureaucracy controls and tames the internet. It is not too heavy handed, so most Chinese do not complain. Just enough where needed.

Queensland Police want access to locked devices

Restricting Complaint is nasty

The nastiest part of this type of law is restricting people's ability to complain about being subjected to them. Much of the ASIO legislation also makes it illegal to tell people if you have been arrested etc.

Like this would stop a real terrorist from telling their mates. It is about protecting the security forces themselves, pure and simple.

Apple frees a few private APIs, makes them public

Microsoft stoped doing this 20 years ago

It was a big deal then. Special APIs that could only be used by MS Office to entrench a monopoly. I think the courts thumped them by vague memory, or were going to.

It is Bullshit

Not tiny drone could destroy the grid. At the very worst trip breakers for a few seconds. And Think about the size and strength of the insulators compared to the few hundred grams of drone.

OTOH, I once hit high tension wires with at glider winch launch cable. 1000 times more solid than a plastic drone. It made a huge explosion as the cable vaporized. But did not seem to do any permanent damage, although we thought it best not to inquire...

Self-driving car devs face 6-month backlog on vital $85,000 LIDAR kit

aberglas

Re: I don't know...

Half right.

Understanding depth by using one eye is a really difficult problem. However, using two eyes to measure depth nearby is relatively easy, and AI labs have been doing it for a long time.

When driving, humans do not use stereo vision, distances are too great. But a computer can have two or more cameras spaced well apart. The hard part is to recognize that an edge seen from the two cameras are actually from the same object. Then a simple bit of trig gives you the distance.

I am surprised this approach is not used. But I suspect that the car manufacturers are more auto engineers hacking AI rather than AI researchers.

The NSA had a real enigma at the RSA show this year. NSA man was showing how people could encrypt a short message and then decrypt it. So I asked him, pointedly, how this could possibly work because there was not Encrypt/Decrypt lever. Just double encrypted to produce the plain text. Just got a blank look.

Oracle crushed in defeat as Java world votes 'No' to modular overhaul

aberglas

Sun was always a little arrogant about Java

Sounds like they need some face to face meetings.

The sun.* packages are used because there are no good alternatives. The alternatives need to be provided well in advance. And with back portable .jars. Some things are just convenient, like base 64. Others like sun.misc.unsafe are essential for some advanced usages.

Java itself was godsend. It made Lisp-style programming popular, introducing garbage collection to the unwashed masses. It spawned .net. If it did not exist we would still have to use archaic rubbish like C++ and PHP.

Australian Taxation Office named as party preventing IT contractors being paid

aberglas

Re: We OBVIOUSLY are missing big chunks of the story. . .

Australia is not (quite) the USA (yet).

Unburdened by any Bill of Rights, we have never had slavery. Nor do we have the US civil forfeiture laws in which police can arbitrarily steal people's money. Nor the extreme plea bargaining against draconian laws.

It is very rare for the ATO to freeze assets. So there is probably more to this than disclaimed. And it will go to court in a few days, unlike the USA.

Webroot antivirus goes bananas, starts trashing Windows system files

Re: But what if we invented the internet all over again

There would be no peer to peer networking.

There would be no such thing as universal email. There would be lots of walled gardens.

The Telcos would control which sites you could use/visit. Only they would be able to produce servers.

There would be no anonymous sites or browsing.

But fortunately, all those things got out of the bag before the MBAs took control.

nbn™ to offer 100Mbps fixed wireless service

aberglas

I just want to keep my 3mbs ADSL

Fixed wireless in my area has been delayed indefinitely because apparently some people think that the radiation will kill the koalas. It is in court at the moment, been there for a long time.

They need to cut the copper, politically. So if they cannot do fixed wireless, they threaten Satellite!

I don't need 100mbs. Don't need 25mbs. Don't even need 12mbs. 5mbs would be nice, but 3 will do. But I do need that 3. Which is plenty to do development with. And without huge latency.

Sure, we could replace FTNN, says nbn™, if you let the unwired wait even longer for broadband

aberglas

Re: "$2,800 to make an FTTC connection"

They should just give the FTTH to everyone that is will to pay, say half the cost, $1,400, up front. That should be easy to do and shut up the Fraudbanders. Then the other 99% of households will be happy with FTTN, plus not having to pay in taxes for services they do not want.

Personally, I would be happy to pay $1,400 for a decent ADSL service. But it will be a long, long time before the NBN gets near my place.

nbn™ builder prioritises easy premises, because it must work like that

aberglas

Prioritizing those that already have good internet

There is a huge benefit of the NBN for people that have no internet at all.

But so little for people with good ADSL that most would not switch to the NBN if they were not forced to by cutting their copper. (We know that as a fact from trials where they did not threaten to cut the copper.)

So what does the NBN prioritize? Those that do not really want the NBN.

It is the wrong KPI. Number of premises is a worthless metric. How many people with no or bad internet have been connected. That is the KPI that counts.

(And for the "Fraudband" screamers, it would have been as bad or worse under the FTTP plan. And that $42 billion costing was a fairy tale for small children.)

Australia: Stop blaming Centrelink debts on its IT systems

aberglas

Multiple points of incompetence

Just because the rules set up by the executives were incompetent, does not mean that the programmers did not also stuff up in other ways.

Given that this is an IBM project, it is safe to simply say that the natural incompetence of the IT department was, in this case, overshadowed by the even grosser incompetence of the management.

Mind you, one should always be wary of claiming that management is incompetent. In this case, I presume that many senior managers got promoted precisely because of their ability to say "Yes" at the right times, without being burdened by facts. Competence is the ability to achieve one's goals.

Competition and wholesale costs, not lack of fibre, crimp broadband in Australia

aberglas

Worst speeds, not average, is what counts

How many people have less than 1 megabit. That is the number that counts.

1 meg is enough to watch Netflix. And also use all web apps.

But less than that and you have no internet at all.

It is the minimum that counts. NOT the average.

Very few people have any need for more that 12.5 megabits. If 12.5 megabits was significantly cheaper than 25 megabits, very few would take up the latter option.

The Soviets could have easily won the space race just by sending somebody one way. They had already successfully landed a probe on the moon, just do another with somebody inside.

Number of connections is the wrong KPI

To quickly maximize the number of connected users on the NBN you focus on those that are easy to connect. E.g. near an exchange, have HFC etc.

But most of those users already have decent internet and do not particularly want the NBN, certainly not at $4,000/household tax subsidy.

Meanwhile, people on the outskirts, who are desperate for any broadband (1mbs would do) get nothing.

And the "fraudband" lobby do nothing to help this.

Swedish prosecutor finally treks to London to question Julian Assange

aberglas

The Swedes can save face

Now that the lesser charges have expired, they can drop this one while still saying that the lesser two were valid. That is all that is going on.

The term "rape" is being abused. It normally implies violence or a threat of violence. There has never been any allegation of this. Assange may be an arsehole, but he is not violent. Some would say that a woman changing her mind after the event is "rape" because the man should have been more caring...

I suspect that this was never a ploy to get Assange to the US, just an incompetent Swedish prosecutor. But I would not bet my life in a small US cell over it. And remember, a US jail is hell compared to a Swedish one.

nbn™ aces the easiest construction target it will have for two years

Use for 100 mbs?

What exactly are people supposed to do with it? Run 100 TVs concurrently? Or 20 ultra high definition TVs? The only reason people buy 25mbs is that it is almost exactly the same price as 12.5mbs, and the latter is not available on BigPond.

Meanwhile, I get by on a 1.2mbs long ADSL line. It is plenty for web, and even development (GIT etc). It can run the TV OK as long as I throttle Windows Update. But the line is slowly degrading. And it will not be improved due to the NBN.
