I typed ifconfig to confirm one of it's ip addresses. OOPS some self righteous @$$hat decided that systemd is so awesome that we should all type "ip addr show" now, because you know reasons.
I don't think the move to using the "ip" command in place of "ifconfig" is anything to do with systemd. The ip command gives more control over the network config than ifconfig, but ifconfig is easier to use in most simple cases. RHEL7 has taken the the dumb (IMHO) decision not to include ifconfig (and all the other Berkeley network commands) in the default "minimal" configuration. For the most part ip and ifconfig happily co-exist.
Surely if systemd had it's way it would be illegal to configure any network device without using NetworkManager. NM together with systemd is an even more challenging environment. There is a reason why most OpenStack howto docs start off with instructions on disabling NM. You don't have to go as far as OpenStack to discover why, any system which doesn't just manually deploy VMs is likely to have major issues.
On the other hand NM can be useful on laptops.
ALL software has bugs, get over it.
It is precisely because all software has bugs that design decisions should be made to limit the impact of those bugs. It's like RAID, all disks are unreliable, eventually the industry twigged that the answer wasn't to make more reliable disks (even though that helped a bit) the answer was to design storage systems where disks dying wasn't a big problem.
When it comes to SW the trick is to make sure that you're not exposed to the risk of bugs unnecessarily. Design your SW so as to limit the impact of the inevitable bugs.
Never unconditionally trust input from outside your code
I'm not sure I'd trust input from inside the code either
a) We all make mistakes
b) At some point someone else is probably going to fiddle with your code who won't understand the limitations.
Getting rid of systemd won't stop buffer overruns.
No it won't be getting rid of buffer overruns, but something as critical to system operation as systemd simply should never be placed in a position where it can be exposed to this kind of attack, or any kind of remote attack. That's not an "I hate systemd" statement, that's a basic security for kindergarten level lesson.
Fixing these issues is going to be a giant game of wack'o'mole where there is simply no need to expose yourself to danger in the first place. This isn't just a bug it's a fundamental design flaw.
You'd slow to a stop and pull over to the best of your ability, using your last memory of the road ahead. A self driving car would have a more accurate memory of the road ahead and know exactly the steering input to get it there, so it could very neatly pull over out of the way.
A few years ago I was driving on the motorway when the bonnet (hood) of my car blew open. Apart from the fact it hit me across the top of the head through the roof, I obviously lost all forward vision. But I quickly realised that I could see out of the side window and could use this to ensure that I was steering parallel to the white lines and armco, secondly my wife immediately realised that because of the way the bonnet had bent she had a better view than me if she lent right up against the side of the car. Together this allowed me to slow right down and then look over my shoulder and see when it was safe to pull across the lanes to the hard shoulder.
Self driving cars will need to be designed to cope with sensor failures and to make decision based on anything that is left to them. Lets hope they do this better than most bit of SW we experience in everyday life.
Many North America animals apparently push roos in the stupidity department.
You don't even need to go for wild animals.
Cat's have no road sense either. They are genetically programmed to assume that they are more important than you are and that you only exist to feed them, so naturally assume that when they want to cross the road you'll just stop. Secondly they are genetically programmed to assume that they are faster than you, so the thought of "I'm not going to make it" never occurs to them either. They just rush on.
I've also got a theory that sheep can't see anything travelling at more than 40MPH. Presumably there is no natural predator for them which moves anything like that speed so why bother to develop sense to cope.
Those price comparison and shopping sites would claim
But I've never asked Google to tell me who can tell where to buy something, I've always asked Google to tell me. So if they are returning links to other comparison sites they aren't doing what I asked for.
If I type in a query saying "Who can tell me where the cheapest place to buy an OkiKoky2000" then they should be returning hits on price comparison sites.
If I type in a query saying "Where the cheapest place to buy an OkiKoky2000" I rather expect them to tell me not say "I'm not allowed to say but I know some other people who are".
For the prices of a ticket I'd expect more legroom, not just free champagne.
My uncle used to regularly commute to the New York on the Concorde and my aunt described it as "not being very comfortable but at least it wasn't very comfortable for very long."
For return leg my uncle preferred a normal plane since there was not real benefit in saving time on the eastward leg. The flight out meant he could leave home in the morning as usual, go into his office in London handle anything sufficiently urgent and then fly to New York ready for a days meeting there.
The only reason Concorde wasn't certified to fly over the mainland United States is because it wasn't built by an American company
and of course the only reason it got to fly into Washington at all was that despite of
Even when flying below the speed of sound, it was often noisier than always-subsonic aircraft
It was quieter than the President's jet, so they couldn't ban it without also banning El'Presidenty
> Developers of other systems don't concern themselves with backwards compatibility as much.
HP-UX had this issue before Windows was an OS. It simply made it a mount option and long filenames quickly became the default, but the option of limiting filename lengths existed for customers who suffered from old applications which didn't handle them.
> We used to call them "newspapers"
Most people know the political leanings of the different newspapers, most make no secret of who they support. Newspapers are also some extent answerable to the press complaints bodies, at least in theory.
With online sources there is no knowing and no one to complain to and no recourse.
> What happens if when there is a flaw in whatever method they use to implement this?
You mean when the civil servant leaves the documentation, including the keys, on the train or when the minister is photographed walking into a office holding a piece of paper with all the details on it?
No things like that never happen, never not even once.
Way back when you used to find Pac Man machines in pubs someone from HP wrote a version for the HP9816, which was a 8MHz 68000 based system so massively quicker than the 1MHz Z80 original. The game was written as a standalone bootable system, I'm guessing based on the PAWS environment, anyway it wasn't written in Basic.
One of the guys in the office could play this for hours, and it quickly got to the stage it was going at several times the top speed of the pub version. When he used to play the pub version he could just keep going till
a) it was his turn to go to the bar and get more beer
b) he needed to return the previous lot of beer he'd rented
c) it was chucking out time (back in the early 80s we still had closing time)
d) he just got bored
The landlord hated him, 10p would last all night
If it is a laptop then use a bloody cable, you will get much better throughput than sharing a wifi link
Very true but a lot of modern low profile laptops don't get an Ethernet port without plugging in a dongle. The RJ45 connector is too big for the laptop's case.
They should of course introduce the death penalty for builds who don't fit CAT6 cabling into the whole house.
The bastards I bought my new house from twenty something years back wouldn't let me come in a lay cabling before they did the plastering and such like. Oh boy would it make life easier if they had.
I find the music stops me being so easily distracted by everything else.
But
The voices are very distracting, I'm useless in big social groups since I can't even filter out the other conversation around me and concentrate on what the person I'm talking to is say.
So music, but no singing, so lots of instrumentals. A plumber introduced me to Joe Satriani a number of years ago and increased my productivity no end.
The problem I have with silence is that I then tend to distract myself.
I've been working there for years, but apparently they've changed the rules. There is an unbelivable amount of red tape that needs to be completed before I can even go and do a weeks contracting in there now and that's before we leave the EU. Heaven help someone from outside it.
> Even if all cars were automated, they still have to deal with pedestrians
And if I know that a auto-car is going to stop then I'll just walk across the road. WGAF!
I'm not waiting for no silicon driver. If the resulting emergency stop causes the meat payload to spill their coffee WGAF! to that too.
"How does your brain perceive the difference --
-- between a blowing plastic bag in the road and a running child in the road?"
I understand your point, but applying the brakes seems like a reasonable response under both of these circumstances until they really can tell the difference.
Well not necessarily. If a child steps out into the road in front of me I'll hit the brakes and pull what ever stunt is necessary to avoid them. If a plastic bag blows out into the road in front of me I'll look in the mirror first. So if that bloody great truck with the driver on his phone behind me is too close to stop before totally me I'll be a little more circumspect about braking. I don't want to die, but I'll die to try to avoid a dumb kid. I don't want to cause an accident for the sake of a bit of wind blown garbage.
We've already had a discussion here about the ethics of a computer deciding between killing a pedestrian (a non-paying human) and killing it's occupants (paying customers), those choices will need to be made and a human driver will make them in the heat of the moment while a computer program will have had to be taught who it should kill in order of preference.
> SGI died when Rick Beluzzo...
I imagine that in effect that SGI died the same day that HP's workstation business died. The day that AMD launched the 64bit X86 chip. Before then HP & SGI owned the performance graphics marketplace because x86 boxes couldn't handle the large flat memory spaces needed by the applications. Once that limitation was done away with the writing was on the wall. PC hardware was going to nuke the specialist boxes because they'd never be able to compete on price and due to the volumes involved would be out spent 1000:1 in development.
> Just a side note: rock-climbing (like paragliding) is statistically one of the safer sports.
Back when I was a teenager I went on a rock climbing holiday in Cornwall and ended up getting carted off to hospital by ambulance. The injury of course was nothing to do with climbing, someone jumped on me in the Youth Hostel one evening as they thought I was having too much fun.
In the ambulance we got chatting to the crew and they commented that they almost never get called out to climbers. Tourists however, they said, were like lemmings and threw themselves off cliff all the time.
> Beer because there's nothing like a beer after a day's climbing.
And a pint for you good Sir.
> Wondering why your post got 3 downvotes. It was spot on.
Probably because criticising VMS on El'Reg is considered illegal.
The Veritas filesystem doesn't put the structural files into a set with any names, so normal accesses can't see them. You need to do into a filesystem debugger before you can get at this stuff. I can't see any benefit to linking these things into a normal file name space.
Plus out the back, we have 8 massive V12 Diesel Generators that would power a small town.
I remember a story a customer told me once about their backup generators. They were on the roof of the building which housed their DC and the diesel tanks were buried under the car park. Every couple of months the generators were tested, they'd be fired up for a few minutes to make sure everything was in working order.
Then came the day of the actual power cut.
Everything went fine to start with, the batteries kicked in, then the generators all started, then after a couple of minutes each of the generators coughed and died one by one.
It turned out the pumps the get the fuel up to the roof were on the wrong side of the cross over switches.
Well printing from W10 on systems that have been upgraded from earlier version seems to be about as reliable as your average politician(1). Whereas my Linux boxes always seem quite happy to talk to all my printers.
(1) on all my updated PCs and from Googling around, lots of other peoples too. You're mileage may vary. I'm happy for you.
Isn't going down the vinyl audiophile thing more like buying a Morgan or a Bristol - loads of money spent on something not as good as mainstream and makes the person who buys it feel special (but look a tit)?
Well perhaps not a exactly a Morgan or Bristol but until recently I had classic car, by any subjective measure it was inferior to a modern car. But who gives a F*** about subjective measurements. Modern cars like BWMs are comparatively boring to drive and of course you don't really drive them, there's a computer buried in the heart of it which does a lot of the driving for you, so there's no sense of satisfaction in all the little actions that go into driving. Don't get me wrong, I wouldn't want use a classic as an everyday car, for merely getting from A to B or for popping down to the supermarket the classic would be a PITA but for those bright Sunday mornings when you want to go out and have some fun no modern I've ever driven comes close.
When it comes to convenience MP3 is fine. Now that Amazon do "autorip" I've got rows of CDs on the shelf still in their wrappers. But without the convenience of autorip I may well not have bought them. I like to have the physical media, I want something I can feel that I can touch and I can own. But for the vast majority of my listening MP3 is good enough and it's really convenient and everything plays it. I can't see a car manufacture in the near future producing a car "radio" that doesn't play MP3, can you?
My classic had a radio when I bought it, but it had an oil leak so I removed it. :-)
Until I can get a 4TB SSD for the same price as I now pay for a 4TB block of rotating rust then articles like this really mean diddly squat.
And the bloody price of rust has stopped nose diving, I could do with swapping out the 2TB drives in my fileservers at home for 4TB ones, but when you need to buy them 4 at a time they're too pricey.
Call me old fashioned (OK, you'd be right).
A couple of weeks back the Wife and I went off to our local for a meal, they've got a number of small areas with just 2 or 3 tables, the one we were in there were 2. Shortly after we arrived a young couple came and sat at the next table. They didn't say a word to each other, they both got out there phones and spent over half an hour engrossed in them, he seemed to finish first and tried to talk to the woman, she continued to ignore him. Ten minutes later she finished and she looked up and started to talk. From then on they were all lovey dovey. Well they were until BeepBeep her phone got a message and she went back to ignoring her date.
What's the point?
If I go on a date, I expect to pay the person I'm dating the respect of "being with them".
If I went on a date and the other party just spent the evening on their phone, I'd take the hint and sod off.
>>IP addresses often do identify an individual
>But not to the same extent as a telephone number.
Well in my case a quick whois will give you my home address which wouldn't be so easy for a member of the public to do for my phone number. Not everyone's IP address is NAT'd to the N'th degree before it hits the net.
> And quite poor virtualization (above the Hosting OS) ...
Not sure I'd consider it quite poor, I think the handling of virtual storage devices in HP-UX is much better than it is in Linux. I really miss the way that HP-UX maps NPIV virtual fibre channels into virtual HBAs in the guests is much better than the way that with libvirt you need to make the NPIV FC visible in the host and then create a storage pool presenting the LUNs as volumes to your guests. The HP-UX design means the guests storage doesn't need to be visible to host and the array can easily present straight to the guest.
