Re: If a false widow is freaking em out just wait till they see a woodlouse spider
Hmm... not seen those. Plenty of woodlice. I'm told that they taste of shrimp, being distantly related.
" Their diet consists exclusively of woodlice which—despite their tough exoskeleton—are pierced easily by the spider's large chelicerae.
The courtship of these spiders is typically aggressive and mates risk injury from each other's large chelicerae. The female lays her eggs in a silken sac and is believed to look after her young after hatching like the "Mothercare" spider (Theridion sisyphium).
They have been known to bite humans if handled. Their bite can be painful but the venom causes no major medical problems. Localised itchiness at the bite site has been reported in some cases"
Re: I live near Hedge End...
The list of things guinea pigs can die of is quite long ...
Top is Respiratory infection (bacteria) from human. Otherwise there are no communicable diseases in common. Next is bad diet. Rabbit diet is bad, too much Lettuce is bad. Lack of water common cause of death, they mostly might not seem to drink much (it varies) but whatever little it is they really need.
I'm not keeping them again. Too stressful. But I wouldn't worry about spiders.
Re: Steatoda bipunctata
Steatoda bipunctata is a species of cob-web spider, of the genus Steatoda, in the family Theridiidae.
It is common in North America and Europe and may be found in proximity to human structures, such as basements or sheds. A nickname for this arachnid is the Rabbit Hutch Spider, since rabbit hutches often make a suitable habitat. The Steatoda bipunctata is similar in shape to the Black Widow spider of the genus Latrodectus and can thus be mistaken for it, although its bite is significantly less dangerous to humans. For this reason, species of the genus Steatoda are commonly called 'False Widows'.
Sudden temp changes kills.
But they live all the way from Amazonian Swamps to Andean snow line. They like snow. At least ours did.
But they WILL attack stuff. We had one that taunted a rook. It knew EXACTLY how far the rook could reach into the outdoor run. We had netting roof. Otherwise Cats & Magpies would try eating them.
Rats would tunnel in to steal g'pig food in broad daylight. Most of the cavies ignored them, but one male would chase them. Our largest pig was size of a dwarf rabbit, about twice size of rat, and similar but bigger teeth to a rat.
Something else might have killed them.
You can buy new batteries cheap!
A "Cloud" OS is isn't an option, that's just a Terminal that relies on the Internet, thus much slower and less reliable than a wired terminal to a server in your own building.
"Clouds" only make sense for people with loads of separate offices all on redundant fibre broadband and probably with their own cluster or (several co-located servers in different data centres)
You can configure Debian or Ubuntu to run sensibly on netbook with "Classic" desktop. Or Mint.
If XP or Linux is too slow it's not configured properly. Uninstall parts never needed and disable any thing that can't be uninstalled that isn't need. On XP "Disable" services, not "Manual".
Learn how to not install malware and up to date Browser with No Script or equivalent. Never add Toolbars, disable all PDF and external Media Playing and Skype plug-ins in Browser.
Then don't run AV. It needs too much RAM & CPU. False positives and false sense of security and not as much protection as "using" the computer properly.
The colour filters needed for colour eInk reduce the reflective brightness to about 1/5th. Colour filtering works with LCD (which is also inherently mono) because the backlight can be x10 to x50 brighter than light reflected off paper.
The Qualcom mirasol might be a lot brighter. But so far seems to be vapour. It works on a similar principle to butterfly wings. But it won't be as bright as mono eInk.

No, Apple wasn't saviour of ARM, ARM helped save Apple. Re-read the article!
Intel ironically got the DEC StrongARM IP & stuff as part payment of some settlement. They sold most of it to Marvell, but not all (they had an ARM based comms chip last time I looked in 2008). AFIAK Intel do still have an ARM licence of some kind.
It seems unlikely DEC was going to replace Alpha with ARM. After all there was even a 64 bit NT 4.0 for the 64 bit Alpha. They might have used it in a Terminal or handheld device or network gadget or SCSI controller I suppose.
DEC is a great loss. Compaq & HP pissed it away. They only wanted the service support aspect anyway, none of the R&D, SW or HW. HP in taking over Compaq and "rationalising" seemed to ditch some of the better products of both companies. Too many decisions by speculators, lawyers and accountants.
Re: so Arm says that Apple did innovate then?
Apple bought an "ARM design house". That team applied its previous skill and ARM IP to produce the A7. The first iPhone used a Samsung developed ARM.
So Apple "natively" are a Product Style and Marketing company. Very little software or hardware innovation. Even most of the style is copied from Braun & Dieter Rams.
But then again MS bought in SQL, Visio, DOS and many more. Original MS Basic ripped off mostly over a weekend from Dartmouth BASIC by Bill Gate's friend. They did really produce Word & Excel (the two most successful Office apps ever?) but ironically initially for the Mac (Lisa MkII copy of Xerox Star) as their own GUI copy of Xerox wasn't quite able then!
Google bought in Maps and Android, copied Java and used Linux. (They are really an Advertising Agency).
The patent system is broken and there is a small amount of incremental innovation by anyone. Often most by small acorns that are snaffled up by pigs.
JAVA internal design concepts based on p-Machine used to run p-code produced by UCSD pascal.
No one designs from scratch and in isolation very often.
Re: And of course....
Sweden allow extradition on Death Penalty charges to USA? Not possible.
Re: Tellies can handle 60Hz input
Yes, but even PERFECT 50Hz to 60Hz frame conversion is RUBBISH
Especially for movement.
Almost all Broadcast is 25fps interlace 50Hz in Europe, There is NO WAY AT ALL to display that as 60fps 60Hz progressive without degradation (blur or shudder) of movement.
Any Picture in Picture the game needs to be running 50Hz 50fps progressive.
Also ANY display of broadcast on a Progressive only panel of interlace source even at same frame rate is degraded compared to CRT or native panel interlace (with strobed backlight).
The very concept of Xbox one is flawed in a world where we have 24fps, 25 fps 30 fps 48fps 50fps 60fps progressive and 25 fps 50Hz, 30fps 60Hz interlace. Not to mention all the different resolutions (more on broadcast than disk).
It's a pity with HD they didn't go for a single 48fps progressive 2136 x 1154 standard instead of the 1/2 dozen or so incompatible standards.
The original 30fps / 60Hz and 25fps /50Hz had to be:
1) Interlace halves the transmission bandwidth. An analogue compression system if you like. Progressive wouldn't have been possible for 40 years.
2) The frequency had to match lighting (or else you'd have strobe bars) and initially local mains (so hum bar on picture would be stationary, hence 24 fps 48 Hz interlace wasn't possible. Video cameras are more sensitive to this effect than film cameras. Later in 1950s the TV Power supplies and Cameras better and so TV frame was no longer locked to mains.
Modern TV was developed 1934 to 1936 initially. Hence the frame rate limitation would last nearly 20 years. Interlace Limitation until MPEG and digital was available to do compression.
It won't save RIM/Blackberry
But it may make QNX more valuable in the eventual firesale.
A great trick/hack though.
They need maybe 5 GUI and 4 OS.
BUT ONLY DESKTOP should be called "Microsoft Windows". Call the others something else. Height of stupidity has been calling ANY embedded version (We have had Win 3.x, Win NT, Win XP, Win CE embedded versions) "Windows".
One Windows & One GUI (even only two) is stupidity.
Maybe one Kernel is possible.
Ha Ha ----->
About x10 to x20 more. Capacity rises just a bit less than linearly, but speed can increase by square law every time cell diameter is halved.
So x16 more capacity and closer to max speed, have x20 more masts. Maybe need x2 channels in Urban/Suburban, but a single wholesale RAN and effectively make every retail an MVNO will double usable capacity on existing masts and allow more channels (needed for very small cells to avoid inter-cell interference).
Small Cells = More capacity and much higher speed.
Like Samsung was ding with ARM about 8 years ago?
The time has come, esp with more Browser Centric Intranet, Cloud and Public Internet to seriously look at Linux as a Migration option.
Microsoft has basically lost the plot since Server 2003.
Lock in to Exchange & Outlook non-email functions and then Sharepoint was among the worst Corporate decisions, allowing MS to hold Business customers hostage.
For me MS 1981 - 2014 RIP, avid supporter of NTFS, and NT since NT3.5 (Our first deployments just before NT3.51 Release). One of the most important IT vendors for Business has worked hard to become an irrelevant Consumer Appliance company.
Some more Boutique Companies may go entirely Mac + Linux Servers, but I fear the Mac will be ditched for a larger iPad with keyboard and the Mac "all in one" monitors will also migrate to ARM and iOS. Cost reduction, same end user price and more Apple Control / iTunes delivery etc.
There are old Windows applications I need, I will look harder for Linux alternatives and as final resort a Virtual Machine with XP (no Internet) or WINE.
Currently 2014- 2015 is looking unpleasant IT wise. Win7 and especially Win 8 simply isn't a viable alternative to XP. Still running Skype 3.8 on XP. Skype 6.10 on Win7 using about 90% CPU. This seems to be a Skype Issue since about 6.7
Some applications bought between 1999 and 2010 still in use won't even run at all on Win7, never mind Win8. Often newer versions more buggy, no worthwhile extra features and the upgrade cost of all these is much more than cost of a new Workstation.
Re: The end is nigh! Really?
Yes, really ...
We had 2.2GHz CPU 1600 x 1200 pixel LCD laptops in April 2002. That's nearly 12 years ago.
so if Moore Law was only 2 years (people often say 18 months and long ago used to say 1 year) for LAPTOPS:
2004 : 1 Core 4GHz, 1G RAM
2006: 2 cores 4GHz, 2G RAM
2008: 4 cores 4GHz, 4 G RAM
2010: 8 cores 4GHz 8 G RAM
2012: 16 core 4GHz 16G RAM
2014: 32 core 4GHz 32 G RAM
Nope, Moore's "Law" was only an observation. Like the grain of rice on square one of a chess board, it was never going to hold true for long. Growth has barely even been linear.
HDD native speed, HDD Capacity, Network copper and WiFi Speed, RAM speed hasn't exceeded linear, in most cases declining improvements.

Not quite Computer HD, Only TV HD
Full HD display
Enjoy a state of the art viewing experience with the Full HD 1080p display.
Why is the entire industry convinced Laptops are only for Video? I had 1200 lines in 2002.
17" 4:3 screen 1880 x 1410 or so would be an incremental step up from 2002.
Still, it's not as bad a laptop as Berger suggests. But at 13" diagonal 16:9 it's a notebook rather than laptop. On negative, it *IS* stupid shiny screen, no ethernet, possibly no card slot.
One for a large handbag/Manbag?
I'd not buy one for any OS.
DAB isn't new. It was Digital for Digital Sake. Like trying to sell ISDN to most domestic users. Was good for small businesses though till ADSL arrived and Fax became nearly obsolete.
The UNUSED useless for anything else spectrum exists to TRIPLE FM spectrum. A £5 (retail) adaptor (running for months on 2 x AA) would add the spectrum to existing FM sets. Some Asian models have covered this range since 1965 and cost less than £25 today!
64 to 84MHz (used in Eastern Europe)
175 to 195 MHz (basically unused except maybe the odd 2MHz of DAB since 1985 in UK and Ireland October 2012).
The ONLY coherent argument ever for DAB has been more stations. This appears though to benefit the BBC and some national networks the most.
Re: Things that need to happen
No, none of those because Digital Radio of ANY system inherently can't adequately replace portable analogue radio.
DAB particularly (or DAB+) is a bad choice.
I used to believe in Digital Radio. But it's a terrible user experience and as an Expert on designing RF, Digital, Software etc, I can't see how it can be fixed. Never mind the power consumption.
Re: Let's look at this...
At any useful distance you are talking uW or nW. Maybe enough to charge an eInk display that wakes up ONCE a day and change it's message, but unlikely even enough for that.
I don't care if they have 100% conversion or 12V. The power simply isn't there.
ANYONE USING SOME ELSES LOGGING SERVICE
Is really really stupid. Zero understanding of
A) Security. EVERY different site needs its own log-in. A universal Login is stupendously idiotic. Even more stupid than using the same password for everything.
B) Why should someone have an account with an unconnected service. ESPECIALLY "bloodsuckers" like Google, Facebook, Twitter (they are parasites on the Internet, though at least Google is almost a worth while one, like leeches for certain skin disorders maybe ulcers)
I stopped using a major UK media site because of this issue. The guy running it can't see what the problem is in
A) Only allowing Google+ login
B) Assuming everyone that wants to use his site is prepared to sign up to Google+
Re: Not visible here
But the INSTALLER offers to install Crudware nothing to do with Filezilla.
This has happened elsewhere (Cnet, Irfanview etc). It's disgraceful, taking advantage of users propensity to click "next" and never "decline" on dialogs. Especially ones designed to mislead!.
You can cleverly craft broken formats to break the program* reading the data (simplest is String Buffer Over runs/ Array bound violations).
It's not necessary that the format is MEANT to have executable code in it.
But it must be six years since I opened MS software to view a TIFF from Internet (it a was a multipage Tiff, which oddly most photo editing SW/viewers can only see 1st page). Is the default Windows Image Preview/Printer application of XP and later Windows vulnerable?
(* or a 3rd party library the programmer of the program used)
A pin hole camera is a light proof box with a pin hole (smaller is better, in thinner foil, but then exposure time is longer).
Perhaps printing your own Smurfs is more pointless. I'm baffled why anyone would waste the plastic printing their own or buy one. The whole point is to "blue peter" style recycle something.
The 3D printer has a lot of value in prototyping complex shapes. But Pin Hole camera is just a box.

Re: 9-inch screen
Just hold it properly.
It's equivalent to a 45" screen 2.4m away held 48cm away, so at 20cm / 8" (a feasible reading distance) it should be usable.
My Archos is 4.3" screen and 800 x 480. So 1920 x 1080 at 9" isn't much higher resolution. However is itactually going to be lower than TV HD resolution?
Never a truer word.
Full of Sic.
Win Win Win?
Win for Consumers, Win for Cisco (more video means they sell more kit to someone somewhere) and a Win for the MPEG-LA. Every individual build probably doesn't need tracked if Cisco does a suitable volume licence deal. Less paperwork per use for MPEG-LA?
DAB : needs x6 as many fill in transmitters as FM to avoid holes in coverage
DAB : Inherent delay in changing stations vs FM. Huge delay to acquire a new Multiplex that wasn't stored.
The problem isn't just DAB, "Digital" at all proves to be a poor replacement for AM & FM. Even FM can't do away with AM, AM is only way to have fully national coverage and trans-national broadcasting.
Satellite, 3G/4G, Internet, Cable, DTT can't replace AM & FM either, only complement it.
Most of the problems with DAB can't be solved by using a different Digital System such as DAB+ (likely to only be used to double number of channels, never for more quality), DRM or DRM+ or DMB or LTE-B or whatever.
Re: I'm Curious
There is no market for Band II (FM Spectrum) other than FM Radio.
No one else has any plan to close Band II. Some countries have only just adopted it instead of FM on 70MHz band.
Actually they SHOULD have added 65 to 85 and 175 to 195 MHz to FM to triple number of stations. A £5 converter that runs off 2 x AA cells for 1000 Hrs would ad the two bands to existing sets. On - off and Hi-Lo. When off you get band II. On you get BandIII or 70MHz band.
Some Asian sets today and since 1965 tune this whole range already!
Be careful what you wish for.
DAB+ has almost no real advantage, except to allow twice as many stations. All the reasons why DAB is inferior to Analogue apply to it.
I used to be a firm supporter of Digital Radio and DRM & DRM+ in particular. I'm now convinced it's technology for technology's sake. There is enough spectrum no use for Mobile to triple FM spectrum! The FM Band II isn't really much use for anything else.
With the end of Band I & Band III TV (1985 in UK and 1999 & 2012 in other countries) and move from VHF Mobile Radio in "fleets" to Mobile Phones there is absolutely no pressure to save spectrum. Which is absolutely the ONLY advantage of Digital Radio. In every other respect Digital Radio is inferior for portable broadcast.

but end of Macs.
As soon as there is a bigger iPad with keyboard cover selling well the Macs will be Dumped. Seen a new Apple Server lately?
Rotating elongated Bead
The simplest is part white and black and rotated by a lever to outer edge at either end. It doesn't need to be hollow, it can clip in to a frame.
But if it has four sides (a rectangular bead) then you can have two mid shades of grey.
We can't do more shades without going to very tiny dot matrix beads at 60dpi or higher as with our minimal parts (starburst) 4 x 3 cells, a part rotated bead would look rubbish and it's too complicated.
I think basically two states is complex enough, on or off. via intermediate mechanical linkage such that only one cell at a time is driven by the 3 x 4 rods from "look up table". The character set wants to be as small as possible. After changing a cell by default the next cell is addressed. Erase can be a plate with rods to engage every bead and push to all white (or all black, which ever is blank)
Re: Logie Baird
His (or Nipkow's really) allows about 3 rows of 3 characters max. It also has no memory.
The static mechanical displays (hinged mirrors, flip plates/disks, rotating beads) can even be "read back" and used as memory.
The various Magic Slate & Etch a sketch ideas don't need refreshed but can't be read back.
The spinning disk needs refreshed at least 11 fps.
I think the rotatable beads or flip plates/disks are best as:
1) Ambient light
2) Memory that can be read back
3) Fast erase of whole display
4) X & Y character cell addressable
5) Possible to use segment bar per cell instead of dot array to reduce cell addressing from 5 x 7 to 3 x 4, much faster and easier to make a desk sized display using "starburst" than 5 x 7 dots.
So though a CRT or neon dots/.segments (or even under driven tungsten filaments) and batteries are possible in 1890s, both are actually far more difficult and complex to drive than the bead or flip plate arrays.
Re: Just use a CRT its not an anachronism
But DC Electricity dates from some time after 1798, at least in 1878 they celebrated a Volta centenary in France. (Not sure if his Birth, death or the Battery). I'm too lazy to look it up.
Actually there is even the alleged Bagdad Battery,
Two modern Steam Punk displays with memory ...
Actually modern DLP projectors use an array of hinged mirrors, doing 40 x 20 characters each made of 11 segments (starburst display normally uses 14, but 11 is possible) with mirrors or the eInk concept ( using rotating 1/2 white & black segment shape beads instead of balls of Kindle etc).
So we need to operate 40 x 20 x 11 = 8800 segments (either elongated beads 1/2 white & black or hinged mirrors). The beads need no additional light source, only need two positions, could have four faces, and are very stable.
The first electrical matrix displays may be 1908. Victoria died 3 years earlier?
12 segments need 3 columns x 4 rows . making the 40 x 20 text panel 120 x 80 X / Y multiplexed.
One set of 60 Punched metal cards can do the character encoding for each 3 x 4 character cell. The minimum is to reuse 1 & 0 for I and O (as old typewriters did) and only have one case = 26 + 8 = 34 cards / characters.
We maybe can share 5 and S and also 8 and B reducing it to 32.
Update of entire display is slow, maybe up to 5 minutes if a 1/2 second per cell is possible. Erase would be fast (1/10th sec) as that can be a single operation without character cell. Per cell access perhaps 1/2 second.
Each bead about 1/32" diameter and 1/4" long I think?
I actually have 4 x 3 matrixed 11 segment + dp (= 12) LED panels. Curiously most starbursts are 14, but it looks like a 14 segment. (some segments are tied together).
BTW LED was discovered about 1912 by a Marconi Employee but ignored. They were looking for a better RF detection crystal and a weak glow was of no interest. It was discovered again in 1930s by a Russian killed during WWII.
Victorian CRT (on Continent the Braun Tube) was VERY dim as it was "cold cathode", no heater/filament. It wasn't till after thermionic emission was understood (Fleming and De Forest, in contrast Edison was technically clueless, he was a commercial person) that the CRT got a heater. Electronic TV using a CRT with photo target as camera as well as display was proposed about 1906. Baird was very steam punk with his mechanical TV based on Victorian era Nipkow Television.
The Disk mechanical TV is limited to under 30 lines! or about 12 readable characters. Using stacked plates as a set of 200 to 300 mirrors (the plate edges) then about 20 wide by 20 high text is just about possible.
Aconite (?) gas lamp illumination and mechanical drive is possible. But it has no memory and needs refresh of at least 11 fps. The static beads, hinged mirrors or flip panels all have memory and the beads and panels use ambient light.
Most Smart Phones still have pop-in cells. No excuse for a Tablet to not have user replaceable batteries. It's a deliberate design decision to build in obsolescence. It would add no weight, cost or thickness to have it designed in on the new Mac or Surface or any Tablet.
This is England?
I think you'll find it applies not just to G.B. but entire UK. Actually it's an EU directive that UK accepted. Applies in most of EU and some European countries not in EU. Probably though the Laptop only has to work for 2 years. Though claims for losses / injury caused are valid up to 6 years.
Apple already got in trouble in Italy for selling so called "warranties" for inside the two years. They must have been studying PC world/Currys and Argos.
Lots of stuff uses soft case Lithium (AKA LiPo) and the batteries are not glued in.
It's to save cost and ensure only Apple sell a replacement and encourage replacing the entire Mac.
They are CONSUMABLES.
It's bordering on criminal that you can't replace the battery pack. Built in "landfill" feature. My Laptop is 1.8GHz 1600 x 1200
On its FOURTH pack (in 11 years) which is reasonable.
On Average the battery will be two years. Maybe 1 year for 20% to 30% of users.
Also Don't forget!
Superman isn't real either.
They scan at good bit depth in mono and RGB and resolution of more than twice the smallest grain size though.
