Is this cuttlefish really all that cosmic? Ubuntu 18.10 arrives with extra spit, polish, 4.18 kernel

Pete 2

Same old same old.

> the obvious question is “what’s new?” The answer is… not a whole lot.

But this is true of almost every Linux [ and by "Linux" we all know that means the kernel and the suite of apps that make up a distribution ] - and has been for years.

The question that rarely gets asked and even less frequently gets a satisfactory answer is: what will I be able to do, with this release, that I could not do before?

And most times the answer is "nothing". For many years now, all new Linux releases have been merely rolling the version numbers on libraries and utilities (squashing bugs and fixing security problems), adding support for new hardware and fiddling with the UI.

The only real change that has arrived in recent years is systemd. But even that is 4 years old, is hated as much as it is adopted and makes no difference at all to the users and the list of functions they can use.

One could argue that stability is a major benefit. That being able to take a user from 20 years ago (i.e. me!) and plunk them down in front of a Linux desktop that they will instantly recognise and be able to use, is a good thing. Apart from some minor silliness, like moving the position of menus and toolbars it is totally familiar. This is very true. But it is not innovation, it is not "cutting edge" and it is not what developers want to spend their time doing.

Linux has grown fat and slow in middle age. It is no longer the inspirational "alternative" it once was. It no longer leads in terms of utility or design. Yet it contains all the old baggage that makes it a hostile environment for people to adopt. Just try adding a new package - download this, edit that, compile the other, add new libraries to satisfy installation criteria, fix conflicts and maybe - just maybe - after a full day of effort and Googling user forums that shiny new app will work.

We should be at the stage where all a user has to do is sit at a screen and say (or type) "I want to write a document" (or letter, email, flame, program, magazine review ... ) and everything just happens. And the same applies to hardware - especially stuff you can plug in like USB. None of these should be issues, but they are all insoluble due to group dynamics and office politics within the community.

So Linux will continue to increment version numbers. Giving the illusion of progress without change. And in 20 years time someone else will re-write this comment about Ubuntu 38.10. That is, if the Y2038 problem hasn't destroyed the world.

Re: You shouldn't be able to get to there from here.

> All of which need the Internet.

But it doesn't need a public internet connection.

It just needs the specific ports to the specific address / URL. And the same applies to bank access. There is no reason for a finance computer to ever need access to Google, BBC, ToR, Facebook or anything apart from a few dedicated, preferably hard-wired, connections. Ones that would be audited and under change control.

You shouldn't be able to get to there from here.

> ... who had legitimate access to the company’s entire payroll, published its contents online using anonymising network Tor.

While that part is undeniable, the employer should have protections in place to prevent a (legitimate) user from either taking a copy of the data to remove from the workplace, or from being able to upload it to an off-site location.

If that means that users' PCs don't have any ability to plug USB drives (or anything else) in, that would be a definite step forward. It would also stop people loading dodgy stuff onto a PC or server.

It it further means there needs to be an air gap between internal systems holding sensitive data and anything with a public internet access then that would be a good thing, too.

One could possibly go further and question the need for any office computer to have general-purpose internet access, at all.

Having those restrictions in place would also go a hell of a long way to stopping the reverse: bad people gaining access to sensitive data from outside the building.

Another source puts the total WW2 amount, dropped everywhere. at well over 3 million tons.

But it doesn't end there! If the researchers wanted to investigate more instances they could look at Vietnam. During operation Rolling Thunder the americans dropped 864,000 tons on the north.

Amounts so huge, that I simply can't process them.

The most interesting possibility would be for an outfit like SpaceX to take it off NASA's hands. Then if they bought themselves a suitably placed "Tracey Island" far from any other country's jurisdiction they could make their launches from there. And once free from annoying things like national laws, taxes and things they could set themselves up with the world's first (and only) extra-terrestrial tax haven.

I am sure that Apple and many other mega-corps would be interested in a slice of that!

> Before taking a pencil to the back of an envelope or breaking out the Excel and pivot tables, it’s important to understand who is driving the migration and what they want

I would suggest that the very first step is to work out who will get the blame when it all goes terribly wrong (though I think we can all guess the answer).

We learned how to migrate all the clockwork-powered computers prior to Y2K. The strategy hasn't changed just because the buzz-words in the sales brochure are different.

The best tip is to employ outsiders to do the work for you. That way, when someone does go pointing fingers, it will be in the direction of people who no longer there (and therefore cannot deny their part in the failure: whether true or false). This is the major benefit of contracting-out work - the indemnity value.

Security procedures are good – follow them and you get to keep your job

Pete 2
Silver badge

Do as I do

uTorrent, WireShark, Powershell, Ccleaner, SnippingTool, FreeWatch, DontSleep, PDF converters and Caffeine were among the more common risky apps.

The report said: "Like security bypass, the use of high risk applications is often a warning sign of something worse. A user will typically install such applications so that they can get around security measures, download pirated media, or engage in more sinister activity."

The real-life reason that people will use these and other freeware off the internet is that their organisation does not provide (i.e. spend money on) suitable secure tools that do what these do. If you need to read PDFs now would you wait 2 - 3 months for your purchase order to be approved? Which manager would accept that amount of delay. IT staff always get stuck on the sharp end of project delays, with little support from above. If they are pressured to deliver but receive no help in getting the tools they need, is it really their fault if they "improvise"?

It has been a source of puzzlement for years - no, decades, why IT workers with admin prvileges are so reluctant to use these for their own benefit. It should be quite easy for any sysadmin worth their paycheck to insert whatever sort of "payload" they choose onto their boss's computer. Or their boss's boss or ..... the CEO. Or even a co-worker who they dislike or who's job they would view as a promotion (that alone would be enouigh motivation for people to secure their own kit).

Go Pester someone else: TSB ditches CEO over bank's IT meltdown

Re: Dreaming

> Or did I dream it?

I think it was probably a dream. The only time I have ever seen something approaching this was in the run up to Y2K. IIRC provision had been made for client companies to even simulate the payments they would be making through the banking system (at least in some limited fashion).

Even the fullest of full regression testing that I have seen has always failed as soon as it has to receive external inputs or transact business with external systems.

This is always going to be a problem for banking systems since they are so completely interconnected. I assume that is one reason why they have so much otherwise obsolete systems and software - nobody has the foggiest idea how it works and they are all too scared to try and change it!

No, eight characters, some capital letters and numbers is not a good password policy

Pete 2
Silver badge

A brick in the wall

There is more to IT security than passwords. And it seems to me that if a determined hacker has managed to breach ALL the earlier levels of security, then a few puny keystrokes as a the last line of defence won't be much of a deterrence. No matter how long, contrived or frequently changed the password policy requires them to be.

All a computer-level password can be expected to do is to keep out the casual, in-office, user who wants to use someone else's PC to send rude messages to the CEO. While there exist admin-level users with universal access, few hackers would bother trying to brute-force a user password - they would go straight to the root accounts and concentrate on them. Same amount of effort required, far higher gains on a successful breach.

And with the security "wall" that all companies have, there are far more easily exploitable holes than this. The whole "strong password" security theatre is nothing more than that. There are many more pressing security problems that need to be addressed before user's passwords gets to the top of the pile.

The fifth column

When Franco was conquering Spain in their civil war, he was reported as having four columns of troops outside Madrid and a "fifth column" of supporters inside.

Most large organisations have many staff who are happy to collect their monthly pay, yet spend a significant amount of effort actively or passively working against their employers interests. Whether those people are actively sabotaging or betraying the company or government department they work for or are just goofing around, doing nothing useful is debatable.

However, it should be recognised that there is a broad spectrum of hostility that does not begin or end with selling the company's IP, phone directory, confidential material or client data. While that can never be stopped entirely, there are basic fixes that are easy, yet rarely implemented.

One would be forced to conclude that even simple things like removing USB connections to PCs and scrutinising outgoing email are not common simply because organisations do not care about security. Preferring to think any breaches are down to lone-wolf employees who are outliers. That mind-set is far more acceptable (to both employers and employees) than recognising that 5% of your staff are crooks!

Come back in 20 years!

> Arguably, it is too much to expect a network which has never seen a certain combination of two categories within the same image to be able to successfully cope with such an image

Although equally arguably few people will ever have seen that combination, either. The problem seems to me, with no experience of image recognition software, that the systems are pretty crap at recognising anything and rely too much on "tricks" such as context, to turn their guesses into even vaguely credible "image may contain ..... " analyses.

Most people would start by looking at the picture as a whole. In this case the interior of a room. They would identify it as such and then work down, from the big things to the little things. It does seem to me that the identification process employed here is simply not up to the standard necessary to contribute anything useful.

It is not unreasonable. When car makers offer "connected car" services, they take on a duty of care regarding the data they collect. A part of that care is to prevent it being used by any party that does not have a right to it. That includes previous owners of the vehicle.

This is a break from the old supplier-customer relationship of a single sell-buy transaction (with warranty obligations). Since the car-makers have elected to create this feature and to make it open-ended, time-wise, the onus is on them to make it work. And not just for the original owner.

Lo and behold, Earth's special chemical cocktail for life seems to be pretty common

Pete 2
Silver badge

So, why don't we still have dinosaurs?

> "Most of the building blocks we have looked at in other planetary systems have a composition broadly similar to that of the Earth"

If being "earthlike" was enough, this planet would continually be spawning life, as it originally formed. Those "respawns" would then start their own path of evolution. So as well as having us, the result of billions of years of evolution from the first time that life appeared, there would also be forms of plants, animals and all the rest that are the product of evolution from the second time that life started on Earth. And from the third, fourth, the seventy-seventh, the 2,916'th and so on.

But we don't. We only have a single thread of evolution that seems to go back to the start.

So it would seem that being "earthlike" is not a good idea for a planet if it wants to start producing life. It is only a hospitable environment for once life has got past the initial stages. After that, being earthlike is not a set of conditions that is suitable for starting evolution.

The conclusion would be that a planet only has one shot at starting to give rise to life-forms. Maybe once they get to the stage of converting methane, CO2 and ammonia into an environment rich in water and oxygen, they have past the point of spontaneously allowing life to form. If whatever life had developed, then died out, it would explain why we don't see other planets' TV.

The trick wouldn't be starting life, but in having the remarkable set of coincidences, luck, and starting conditions to allow life to avoid all the extinction possibilities in the billions of years after it forms, to eventually give rise to intelligence. Or us!

Re: it is only fair that we fine some of theirs back!

> They're being fined for illegal behaviour

As were the european companies. With any global company you can always find some wrongdoing somewhere. The only question is how to deal with it. Whether you try to correct it, mitigate the damage, or just treat it as an opportunity to get some "free" money.

And fining foreign companies really is free money. It costs the prosecuting country next to nothing and causes them little or no hardship.

The UK seems to think the ignominy of being found to be breaking the law [ sharp intake of breath! ] is enough - the UK fined Facebook half a mil (how they must be laughing now) - and presumably paid that with Zuckerberg's credit card. And forgot about it just as quickly. But at the $ billion level, the cost becomes noticeable, starts to act as a deterrent for next time and the restitution could actually do some good - and not just with drinks all round.

Yes, open plan offices make it less likely that people will chat to each other. Not only are they doing so in plain sight of everyone else - including the boss, but they are much more likely to be politely asked to STFU by all the surrounding people trying to get on with their work.

But the research sabotages its entire credibility with conclusion:

First mistake: trying for perfection

> suppose our algorithm is looking at a vast amount of data and making a decision about whether a person has a disease

While there are benefits to designing an AI system to be as good as it can be, as with war strategies: no algo survives contact with the real world. The crucial factor is that a new implementation should be better than the one it supercedes. Further improvements can be added later, in the light of experience gained.

The second mistake is trying to be too damn clever.

Using the shopping example, for instance. A better design - rather than employing some dimly understood smarts to make a determination - is simply to ask the visitor Do you want to look at men's clothes or women's?

I fully appreciate that the example was merely illustrative. But in the real world too, sometimes it is better to let the user decide, rather than having a machine choose for them.
