Re: I don't get it
Simple reason: Gatling guns, close-up interceptor defences, etc. It is a constant arms race. Presently, it looks like supersonic, sea skimming missiles like P700 and Sunburn have a slight advantage. That is probably short lived as anti-missile defences will be upgraded to deal with these. In any case - the situation there is a close call.
Compared to these a sufficiently _MANEUVERABLE_ long range (20 miles+) supercavitating torpedo is nearly impossible to intercept. You simply cannot build an interceptor which will pull the required Gs and speed under water to get itself into position to deal with it. So your only option is to saturate its entire approach sector with depth charges across the whole range of depths and pray. You also have to do it sufficiently far out just in case someone has put a 0.5Mt warhead on that bugger. That option by is presently unavailable - there is no fleet defence ship or aircraft capable of launching the required salvo size to the required distance (you are looking at something like the BM21 or similar missile launchers (20km+ range) with proximity/depth charge warheads using some guidance/at-depth loitering and most likely multiple of those per carrier group.
Re: Because thats what sea life wants!
Sealife? I did not know that USA carrier groups counted as sealife.
Though with DF21 from above, this from below and a couple of imported Sunburns launched from cloned (or imported) Su-34s they will definitely be entering the endangered species book (at least as far as the Taiwanese straights and the Yellow sea is concerned).
Re: Re "which could potentially bypass missile defences"
On a more serious note, I'd say it could potentially bypass today's missile defences.
Today - yes, yesterdays' - no. I love the smell of hypervelocity missiles encountering a baloon barrage early in the morning. It smells... it smells... like burning money...

How quaint... Nvidia reinventing crusoe via Arm. Just this time it is microcode optimization of arm instruction set instead of run-time optimization of VLIW interpretation of x86.
I just choked on my coffee... What's next? Hiring Linus Torvalds?
Deja Vu all around.
The more interesting point here is who owns all of old Crusoe IPR. Intel bought and perpetually licensed some (but not all). What happened to the rest?
Err... That does not fit my understanding of orbital mechanics
Moon escape velocity is way lower than 11.2km/s. 11.2km/s is earth. All you need is (if memory serves me right) 3 km/s or thereabouts to escape the moon gravity well. Then you fall into the 11km/s gravity well towards Earth.
In fact, if you align yourself correctly you can slingshot to > 11.2 and escape the Earth + Moon gravity well this way (long range probes regularly do that by doing a few Earth-Moon slingshots). That is what makes the moon potentially attractive as a space base (though frankly, its Lagrange L1 and L2 are way better than the moon itself - you can nudge yourself out of these using only a minimal amount of propellant).
Re: Works all ways
That is the case if the technology requires signficant tangible investment and cannot be reproduced locally. So silicon, advanced material tech, etc - all theoretically fall in that category. Practically - they are all in China already.
Software does not fall into that category. Even North Korea can write the software it needs nowdays.
In fact, the west may find it more difficult here as the number of qualified software engineers (total and per capita) and their productivity is significantly higher outside USA and UK.
relied on good coding and engineering efficinecy to compensate for brute force
No it did not. Same as for weapons it relied on maths. I am going to give a weapon example here (space tech was not that different).
How does West build a AAA system. It has a corporation (Raytheon, BAE, Matra) write the most complex piece of rubbish realtime code known to man to achieve the highest possible probability of hit with the smartest possible _SINGLE_ missile (plenty of examples, Patriot is not the only one). Efficiency is... cough.. cough... sub-95% (that is if Raytheon, BAE, etc is to be believed, actual engagement so far has shown much less).
How did Soviet Union (and Russia still continues) build an AAA system. It has a couple of math PhDs working on Optimal control problems (I know some of them by name by the way) define a _MULTIPLE_ pursuit problem, express it via differential games theory (and more recently differential inclusions), define the system of equations to solve it. The result can be coded with high school level of coding. You hook it up to fire control firing _MULTIPLE_ relatively _DUMB_ missiles, according to the equation solution (it looks very wierd by the way - it fires missiles into open sky way off from the target). Result - Buk (the internal, not the export version). Letality - 99%+
Same for P-700 Granit/Sunburn (the non-export version) vs ships and so on.
By the way, I know there is a method in this madness - the reason Raytheon and Co are doing it is because they will not be able to get the barrel of pork they are getting now if the solution is a small notebook of equations (instead of several men-millenia of realtime code).
Re: Hardly breaking news
Predominantly arm and predominantly working on arm is a different story.
The interesting announcement is proper Exynos support. Presently the only thing that works on these are kernels from vendor repositories such as 3.4.0 (yes, 0) for the ARM Chromebook. They have breakage across the board in various key subsystems which are by default disabled in the original crhomebook kernel including basic stuff like NFS. Other SoCs are not much better. If you look f.e. at kernels used in various Android phones, etc you will see a mix of 2.6.33 and an occasional 3.0. Off the top of my head I cannot think of a phone or tablet that is beyond 3.4 and which will work properly using the generic kernel off kernel.org without a raft of vendor patches. There are in fact only a handful of SoCs which are "open" enough to run with a stock kernel and for some of them there is no way in hell to get the actual kernel mods (in blatant violation of the GPL).
So if we have a stable non-3.4 kernel that finally has decent Exynos support, that will be quite interesting. Ditto for other SoCs.

Re: Upgrade, use old one as backup, rinse, repeat.
I do the same on a house scale. Old drives from the house main server RAID set are first re-purposed as MAID for media, then as backups, then as desktops (going all the way back to the days when the server was a K6 with 2 40GB Maxtors).
The current set is due for a change soon. I will probably not put WD though (my luck with them has been terrible).
Re: TalkTalk blocked my site
I've checked my three WordPress sites, and none are blocked.
They may be shortly. Talk Talk blocker is not real time, it walks your site after one of their subs has visited. So if you find it blocked in half a day or so after their filter processes data do not be surprised.
Re: I have argued for many years
1. it's too broad: for example 'possession of material likely to help a terrorist'... a map of the London Underground? A recipe for gunpowder? Lunch?
Why go so far. Example the brain of a chemistry degree educated person. According to UK legislation the possession of my brain would be a lifetime jail offence because it contains:
An MSC in chemistry from the days when we did study toxicology from a chemical weapons perspective as well as proper organic synthesis. How would you like that Tabun, with TNT or hexogen sprinkles? All I need is to dig around the more dusty corners of it for the correct syntesis steps for it.
This law if applied literally should lead to immediate jail time for:
1. Anyone with a Chemistry Degree
2. Most people with Molecular Biology and all people with Microbiology Degrees
3. Most electronic hobbysts and pretty much anyone with an electronics engineering degree
4. A large fraction of degree educated software developers
5. Most people with civil engineering degrees. After all, the knowledge of what it would take to knock out a building is the most essential possible material of use to terrorists (and so are things like how to build gas pipelines, etc).
Re: So sad
Mandatory KAL007 reference
The more appropriate reference is Siberia airlines flight 1812 which shows that Ukrainian military has the experience in shooting them too. So nothing new here.
Dunno about UK
Elsewhere in Europe up to the late 1940-es births were regularly recorded up to several days after the fact and birth certificates issued with dates different from the actual birthday. My late inlaw birth certificate was a couple of days out of date, one of my dad's best friends and university roommate had his 5 days out of date. To heck, some countries like Greece did not have a proper birth register and were recording births as they please up to a couple of years ago. That provided a lovely business model for some of the local "minorities" which claimed benefits for the same child 4-5 times based on registering the birth in neighbouring districts. Before pressing downvote google Maria+Greece+Blond (her "parents" had her birth registered 3? or 4? times).
So having a birth recorded a day late in the 19th century? Even in a well off family? I do not find this out of the ordinary. In fact, any date on a birth certificate not issued by a hospital and before the days of national birth registers is _NOT_ primary evidence.

Unfortunately, the only known solution to the password problem equates to a full loss of internet anonymity and privacy. Namely, you can drop the passwords altogether if you use client certificates (and tie the important ones to a physical key storage). So for the time being we still use passwords - they are like democracy (as per Benjamin Franklin quote): they are bad, but we are yet to figure out anything better.
Re: If I coat my car with this...
Radar - most likely no. The cops have mostly switched to IR laser guns and this should be perfect for them. Ditto for any laser rangefinder - there will be nothing to return back, so this clearly has some very obvious applications.
Re: Use a sword
That knight probably never saw actual battle, then. Swords leave horrific injuries and are usually wielded with very uncivilized anger.
Usually - yes. If you want to be a swordsman and live to a retirement age - no. Sword requires clarity of thinking and control of emotions to be effective. The moment you "use your anger" is the moment you die (assuming you are trying to engage someone who is competent with the blade - they will make a shish-kebap out of you).

Re: Two thumbs up to Theo DeRaadt ...
Not so fast.
I am not. Theo's lot has refactored for security and maintainabilty:
1. Most of the BSD codebase (both Net and Free have taken back quite a bit from the Open tree).
2. Most of the original unix utilities - the whole net tools/inet lot, cron, etc.
3. Bind (talking of hairballs nothing can compete with Paul Vixie code - even openssl)
4. God knows what else. 1,2,3 are just off the top of my head.
If any team is capable of refactoring SSL it is them. Not anyone else.
Re: Two thumbs up to Theo DeRaadt ...

Or Bulgakov, Pasternak, Vysotski, Okudjava, etc - pretty much any Russian writer from the second part of the 20th century wrote in a way that has 5+ meanings in it. Part of expressing your thoughts while living in a police state I guess.
We should probably learn some lessons from them. It is becoming useful.
The announcement is also factually incorrect
As far as slideware goes the biggest rocket ever to be planned is still Energia in its Vulcan configuration (175 metric ton to LEO). That is 45 tons more than this. Energia was successfully tested in its Polyus (4 strap-ons, satellite payload) and Buran (4 strap-ons, shuttle payload). From that to Vulcan is just one step - attach the extra 2 boosters. The components from that are proven too - the engines used in the Energia (with some modifications) lift Zenit (Russia) and Atlas (USA) rockets into orbit till this day.
Otherwise, the SLS design is clearly guided by one single thought - "No Russian components". However, instead of licensing indigineous USA tech from Elon Musk, the SLS team quite clearly prefers to go technologically backwards to the days of the shuttle launcher design. It is a technological step backwards. It can bet that it will be both more expensive to run and more expensive to build than the next Ariannes or anything Elon or the Russians have in the queue. All in all - a typical government handout.

Re: Easy access?
Anyone who has access to your kindle can pretty much shop their brains out. There is very little protection against purchases and this is by design. Kindle is actually not the worst offender - Kobo beats it by mile. So from that perspective FTC has a point. Kind'a.
The level at which FTC does not have a point is that all Amazon purchases result in an immediate email report in the account holder inbox and are clearly visible on his device. Unless the parent was an idiot to set-up a fully separate account for the kid, with an email they cannot read and stick their credit card into that they will be getting full report of what the kids are shopping. So effectively the kindle account is a "family account" with an arbitrary number of devices associated with it while Google and Apple accounts default to a more personal and per-device setup.
I know a few households which have moved from Google Play and iDevices to Amazon exactly for that reason: "Sure, shop whatever you want - just keep in mind that I will get the bill 5 mins later and I will know what you bought". That will probably not work with on under 8-year olds as "dad will know" is not a sufficient inhibitor to a "more weapons" buying spree. If your kids are older it is the best option out there. Definitely better than Google or Apple. So will I by the way - I am definitely going to switch to KIndle's for the kid's devices over time as I swap them out as it gives me more parental control at all levels.
As far as refunds, Amazon is the only retail experience I have never ever had an issue with refunds. You ask for a refund - you get it outright, end of story. No Tesco style "you opened it you bought it".
So all in all, Amazon may probably have a case here.
Bad software engineering
That is exactly why a (V)SAN should be able to support rate throttling and andvanced queue management for IO operations in software before it even hits the controller. As any network engineer will tell you, throwing "more bandwidth" at a congestion problem is only a temporary replacement for active queue and congestion management. Storage is no different (regarldess of how much does it love to pretend that it is).
Take some slightly bigger server(s), throw some more cores in and voila, you just managed to congest that controller queue once more on "supported" hardware.
You should shop around a bit more if you pay £500
Actually, no I do not. In order for a 10G NIC to push 10G in real life you need multiqueue, adapter based hashing or flow matching and hash control at the driver so you can tell the OS to map consistently flows onto their matching consuming cores.
The 320£ or so NICs do only a fraction of this functionality. So while theyconnect at 10G pushing them to 10G in a useful manner is not feasible (or will cost you double the CPU compared to a decent NIC). So you spend 180£ less on a NIC and have to shell that in cost of extra cores in your box (or even double that).
The lowest 10G NIC worth buying on the open market at present are the Broadcom bnx2x series which depending on the actual type of 10G interface in them retail in the 500-560 area. You also have to tune them to your job too. It is nowhere near automagic on any OS.
Even that does not do all I would like to do as there is no deterministic flow matching. For that you need to check for a few more 100s in your wallet.
10G adapter cost per port is still quite significant. I develop on an 8 core Athlon, which costs 450. The extra 10G Ethernet costs north of 500£ alone. This sounds like a rehash of "direct attach" cabling at higher rate and using a customer MAC layer (probably to avoid some royalties).
As far as 40 being already in the market the incremental cost between 10 and 40 is such that there is a market demand for something in-between.
Re: So you can now legally ask for flexitime?
[Wait three months]
Nearly. They are now obliged to provide a justification for the no. This is something HR can do once and they can use it from now onwards.
The result is that businesses which do not want to say yes or cannot say yes for valid reasons will continue saying no. Similarly, businesses which were amenable to this before will continue saying yes. So all in all, nothing has changed as a result.

Frankly, any supermarket is a disreputable source as far as "own brand" electrical goods are concerned. They are sourced in a manner similar to horse lazagna and slavery prawns by the same sourcing department.
It does not cost much more to get a genuine charger or a proper CE marked 3rd party replacement nowdays from a proper online computer supplies shop. Misco/Global Direct and the More group taken together stock pretty much everything under the sun.

No bricks will survive above category 3 tornado.
The only thing that may stand a chance is something half-dug into the ground, with nice aerodynamic shape and some tank grade armour plating to go over all doors and windows when things get ugly. Effectively "a nuclear shelter of a house". This will cost ~4-5 times more than current construction sans the armour cover for the windows and doors (just the dug-in concrete shell). With the windows and doors you are looking at 10x times or more. I do not see anyone starting to build any of these any time soon.
Re: It'll calm down eventually.
It will not. For a different reason.
Try being a startup and showing the VCs a payroll with a 2+ qualified sysadmins (to ensure that a bus running over one does not cause interruption) and some local kit (so you have a viable DR and cloud-to-cloud transition strategy).
You will have your arm twisted until you move the whole lot to the cloud, because the cloud is good and cloud is infallible. The "engage VM, disengage brain" happens at VC/financing level, not at engineering level. All of Trevor's arguments (which I agree with and practice myself) will be brushed aside and brain shall be disengaged.

Re: Problems with SIP?
Just a few comments:
0. Use strong machine generated password for all extensions even if this means getting rid of old SIP phones which cannot do more than 8 characters or special chars in the password.
1. Make sure you ACL any extensions to specific destination ranges. F.E. ACL any extensions that are local only to the local LAN so they cannot be re-registered from outside. This is especially so for phones that cannot do strong passwords.
2. Make sure you use _NON_ numeric usernames especially for outside extensions (just map them to a number in the dialplan). F.E. My-crappy-android-phone maps to 6731.
3. Set call limits.
4. Blacklist any Palestinian authority networks completely (you can get their address ranges from RIPE). 90% of brute force SIP scans I have seen come from there, rest are US based). The idea is - they brute force an extension password, register and then clock to a premium rate number in Maldives, Mozambique or somewhere else they control. If you have the correct ACL they cannot do it. If you have call limits they also self-throttle themselves (they try to originate 4+ calls so a 4 calls-at-a-time call throttle is an automatic killer). No comment where your money really goes as Hamas uses the same address ranges.
5. Blacklist all countries you are not likely to dial or pin-protect them in your dialplan.
6. Do not use 15060, 1506X, 25060, etc as a security through obscurity, these are scanned too.
7. If your phone supports it and if you have the time to set up SIP/TLS always do, it is well worth the effort.
8. If you are asking where do I know all that shit from - well, not doing it has costed me 40£ a year and a half ago. I was lucky - I had a call throttle and the idiots self-throttled. I know some people who have not been so lucky to the tune of 500$+
We are nearing peak advertising
The immunity to advertisement disease has infected most of the internet and is spreadig to the TV and other legacy media.
This is actually a development for the worse as it will mean more infomercials (including fraudulently disguised as real news ones), more placement, more endorsments and other sh*t. While we are becoming well trained to dealing with personalized ads (and ignoring them) the logical step further (personalized fraudulent product placing pseudonews) is likely to take quite a few by surprise.
It is only a matter of time until browsing history, shopping history and internet surfing habits are combined to adjust your "news" to ones that are commercially viable. It is solely a matter who will do it first: MS NBC, Amazon Washington Post or whoever Google (as usually late to the party) will acquire next.
