Re: Analysts! Analysts! Analysts!

Nokia messed up around 2001 or 2002. They long ago passed the event horizon.

Demise of Crystal, destroying Trolltech/Qtopia, Maemo and Meego shows that.

Even if they had Early Adopted Android they would be on a nosedive today.

Why somewhere else?

Why are some parts of science always looking for ET source for original Organic compounds? They had to start somewhere, so surely the most likely explanation is that the ones we have arose (by whatever mechanism) here. They seem to be anxious to have a "creation myth".

Also creatures don't "spring forth" from DNA. Unless you are one of those tiny creatures in the ocean or a Bacteria then Sex between Adults is required. Resulting in eggs or live birthed young.

So both papers seem as likely as Scientology.

If you think life "evolved" rather than "special creation", why not evolved here from scratch. Also if "life" can do it here, then probably "life" arises EVERYWHERE the conditions are suitable, which is likely not limited to our Terran environment. Or if they claim it came on an Meteor where did it start, or was it always somewhere since the Big Bang (Turtles all the way down).

Lets have some logic.

Android spanking iOS in world's BIGGEST mobile market

Stylus vs Touch

"The iPhone is a beautiful product that revolutionised a whole industry."

No, it didn't. It's nicely done, but it used commodity parts apart from the OS and case. The change was coming anyway. I evaluated several prototype (easy to use) touch screen phones that ran Linux before iOS or Android appeared.

The earlier PDA Qtopia was optimised for stylus and resistive screen (win95 style WIMP) the later "Phone Edition" Qtopia was optimised for finger and capacitive screen use without stylus.

The reason for PDA and later phone stylus input on Resistive screen was the "holy grail" of handwriting recognition and sketches / annotation. Once the emphasis was on Browsing and mostly information consumption rather than creation using finger input and capacitive screens (both nearly 30 years old too) was more logical.

The ideal would of course be a combo screen that can do either stylus handwriting & sketches and finger gestures. Gesture based input is pre-1988 as I worked on a Mono-touch screen project then and the boss already had a list of gestures and what they should do (I think "filched" from Xerox, which before the mouse based interface was adopted had dabbled in "pen" based gesture computing.)

iPhone was successful marketing with a very slick gui. Nothing original. No special HW either. If there was any justice and honesty and proper evaluation of Prior Art the USPO would have only awarded patents to pre-iPhone companies and only for the GSM, CDMA, 3G aspects. Everything else in all mobile phones is prior art or just "style". No SW /GUI feature should get patents ever.

In two years time Linux based system(s) will be a fine replacement for my XP.

A tablet will be no problem. A suitable 1600 x1200 or better laptop will be harder to source than a decent OS.

2048 x 1536

I'd love that on a 14" to 16" laptop. Or on 11.5" x 11.7" active area eBook so as to read US & European technical PDFs actual size.

I'd have thought that with 16M colours, and sub-pixel addressing that you only need 120dpi to 150dpi on any tablet.

The iPad3 is 9.7" so it's about 264 dpi which just a waste of power.

Un- Aliased B&W text needs to be 300dpi to 600dpi to look really sharp. 180dpi pure white or black looks jagged. But if you anti-alias then you can use 1/4 resolution, so 150dpi is nearly as good as 600dpi. Laser printers can't as they either put a dot or not. But eInk can do 16 shades (enough) and LCD/OLED about 256 shades.

So decently done 133dpi LCD can look like over 500dpi. Add subpixel addressing and you nearly double the effective quality.

264 dpi (the iPad3) needs nearly 4 times the TFT power as as 132dpi as it's four times as many dots.

Apple egotisim wining out over common sense.

Add visual acuity. Not all iPads are owned by teenagers. Over 80% of adults won't see improvement above 150dpi for anything shaded. Why do you think colour photo resolution on books and magazines is about 150dpi?

Then how many adults should be using "reading glasses" and are not:?

People seeing my 15" 1600 x1200 screen laptop are first:

Staggered by resolution.

Second

can't believe it's over 10 years old.

It's 133.3dpi and yes, sub pixel addressing works to make text look clear and smooth (though the default settings are not the best, but you can manually "tune" it).

I'll buy a tablet when it's eInk and 8.5" x 11.7" active area at more than 120dpi.

Most of the cheap 7" androids are opposite extreme to iPad3 with having a useless 800 x 480 resolution. My 4.3" Archos is 800 x 480. 16:9. It's too chunky for portable and too small/low res for eBook or Internet sensibly.

I think a 3:1 format might work for a phone for scrolling pages 1440 x 480 Like LG Chocolate shape,

But 4:3 is better than 16:9 for a larger Tablet. Apple do have that correct, though for large "eReader" that would give 11.7 x 8.775 (US letter size needs 8.5" and Eu A4 needs 11.67")

Re: Blame your tools. not your ipad

"Why DO they do it as image per page? "

The Archos 605 WiFi had similar problem.

PDF far too slow and awkard

You needed to build an ancient version for "Flash" (v8?) to work and too slow

HTML problematic on page size. Nearly impossible to have "pages" filling screen well but not exceeding slightly triggering scrolling. Scrolling is evil on eBooks.

So people generated .png and .jpg images...

Fixed Page width is easy enough on HTML. Fixed page length is a pain.

Win95

Was really too orientated for Games.

Companies that installed NT 3.5 / NT3.51 servers in 1995 and held off till NT4.0 to buy new computers saved a lot of grief and money. WFWG 3.11 with file & print sharing off, 32bit TCP/IP, decent graphics and decent 32bit Disk and a few other tweeks was superior to "out of the box" Win95a for Business.

Also in 1996 there was little need for USB in business. Professional scanners used SCSI as did Professional backup etc.

Oddly on Win 3.1 /WFWG3.11 I had a 3rd party spelling checker that worked with ALL applications. Why now does each application have it's own or none and separate dictionaries for each?

I have WFWG 3.11 on CD via MSDN clients disc years ago and about 5 sets of Word 2.0a with licences/Manuals. I copied the Word 2.0a floppies to "gold" CD about 8 years ago.

There are better VMs to run Win3.1 in probably than the Oracle one.

Re: When?

"They don't work unless they are plugged into the mains, so how can they talk to each other without mains wire?"

But they do. They only need mains power. Run one off a Generator, Inverter or UPS(unplug it after turning on) and with a reasonable 4 way socket strip extension cable and they will connect. The longer the "aerial" (extension cable) the bigger the distance.

The fuse box doesn't block it. They radiate very well from the lighting wiring.

You can get attractive skirting "board" that is concealed trunking and use a "router" to put slots under a door saddle to hide cable. A self adhesive trunking with clip on cover in a corner up a wall.

Running cable around outside of house too.

Convenience and lack of effort / imagination isn't an excuse to to flout international standards. These are ALL self certified using the wrong tests. They are ALL transmitters and ALL fail RFI testing when tested properly in a "real world" scenario and carrying data.

Interference

"Try as I might, I couldn't get the Netgear kit to interfere with either my DAB radio or the FM tranny I have in the kitchen. Well-behaving powerline adaptors are 'notched' to prevent them transmitting on used frequencies, and in all instances I've seen of powerline kit causing noise, the receivers have been placed near the adaptor."

Not a scientific test. What is your DAB and FM reception level?

What does it do on MW, Shortwave, VHF Low (42 to 76MHz), CB (27MHz)

When was it decided anyway that only FM & DAB is protected Spectrum?

Re: Hahaha

More than 6,000 years ago?

The predecessors to the Akkadian Empire certainly had fire. There may have even been an earlier "empire" before the "city" of which was likely more than 7,000 years ago as at least a fire burning village.

The Elamite civilisation is about 6,000 years ago.

The only reason we know anything much at all is survival of clay tablet writing preserved because the places got burnt.

If there was a civilisation 10,000 years ago or 20,000 years ago they inconveniently didn't write on clay and set fire to the city. Anything else other than cave paintings would be gone.

There is some suspicion that some cave "art" might include "writing". Which would push back literacy + fire to maybe 20,000 to 50,000 years. Maybe but dating can be controversial.

Re: Interesting comments, decent article.

RE "Just to be pedantic: QAM is used on cable, Freeview uses COFDM.

Each Carrier on COFDM uses QPSK, QAM16, QAM64 etc. OnDigital did use less robust QAM to fit more channels. LTE, WiMax and Flash Mobile systems use from QPSK to QAM256 on each carrier on their COFDM system. OFDM/OFDMA/COFDM can use from 30 to about 6700 or more carriers per channel or Multiplex. Cable uses a single carrier for each channel

Technically COFDM, OFDM and OFDMA are really encoding techniques. They all use QPSK or QAM for the carrier modulation.

Satellite OTH uses QPSK or APSK.

Mobe hackathon contest spits out Wi-Fi-by-bonk app wonder

Mage

Can't be done with QR or hard?

No, ALL those can be done by QR code.

The Pill application can even be done easily with EAN code on pills and QR code on prescription to set up the application. Cheap and simple to print a QR code(s) on the prescription.

For the WiFi application "reading over the shoulder" is irrelevant. It's just a simple way to input the password, freely available, but only such inside the restaurant or whatever.

NFC is still a complex solution looking for a problem.

In most cases you only need a unique ID. So in shopping and no need to keep receipts for returns and track back to source the EAN is maker and Product. You just add a second serial number bar code. The unique ID is thus EAN + Serial number, allowing a serial number per product.

Then there is complete traceability and if you used a Store "points" card no need to keep receipts for returns. How do I know? I implemented this already on Printer consumables for a large Multinational. Each item got a 2nd "1 D" (not even a QR code!) code and scanned in on receipt from Wholesale/Maker. Then complete traceability. The customer would scan a Printer/fax/copier and the app would tell him what to get from local store. (s)He would scan it to get it out (next stage would be a Vending Machine type dispenser on site). Old cartridge scanned to recycle bin. This can all be automated.

At the high end running an OS the ARM has been displacing MIPS and x86 for years and growing.

At the low end they didn't exist. x86 can never ever eat that. The M0 and M0+ etc eating into 8bit market except for smallest cheapest 6pin to 28 pin devices.

Routers, Industrial controllers, set boxes Tvs that did use x86 are using ARM, MIPS, ST20 (basically a Transputer). ARM is growing there.

Microchip 18F PIC and MIPs core devices with USB and Ethernet.

Re: March of the neophobes

"Windows 8 is the world's first device-independent operating system."

Nonsense.

BSD, QNX, VXworks, GNU-Linux

Even NT Windows around the 3.51 & 4 versions supported MIPS, PowerPC, Alpha, Alpha64, x86(32bit mode only). There is an embedded "GUI-less" version of NT4.

I had a Debian based VOIP 4G handset with touch screen and ARM cpu before iPhone was on sale.

Have a look in the Arch directory of Linux Kernel source. MIPS, ARM, PowerPC, x86 (even on Geode), x64, and many more.

Most Servers, Setboxes, HDTVs, Routers run Linux Kernel on a bewildering variety of CPUs and HW.

Only the non-NT Win2.x, Win3.x, win9.x and ME was limited to x86 only and user computers (no server versions). There was an embedded version of Win3.x for Cash Registers and ATMs, but it was x86 only. WinCE ran on a variety of CPUs originally, only later it narrowed down to ARM on WinPhone version.

Re: What to do, what to do?

Only some editions have a downgrade licence.

It can be difficult to find drivers.

I think this will benefit OS X, Android, GNU-Linux (Such as Redhat, Centos, Debian, Mint, Ubuntu). Migration from XP will be even slower. Over 40% of PC users still use XP.

If you are using a high end Laptop or Desktop bought since 2002 the need to upgrade (other than for gaming) is hardly compelling compared to 1992 to 2002. Especially for business. This is part of the reason for big growth of Tablets vs Laptops/Desktops. People are getting a Tablet and KEEPING their older PC.

I have done support for Vista & Win7. MS has progressively been losing the plot on OS development since NT3.51. I blame the success of Win95.

Windows 7 is nothing more than what Vista should have been and ought to have been free to every Vista user. A lot of machines sold with Vista are now running XP or Win7.

Windows 8 looks like a genuinely new version of Windows. Maybe by Win 10 it may be sensible, but it looks like MS has been seduced by the iPad. They need to notice that Mac Air doesn't run same GUI or version of OS as iPad and iPhone.

With WinCE / Winmobe they made the mistake of copying the Desktop GUI. Now they are making the mistake in opposite direction. Really you need 4 to 6 OS versions and DON'T give them the same name. Or at least 4 GUIs:

1) Small to Medium Phones

2) Very large phones to tablets

3) Regular sized stuff with keyboard and mouse and mostly used for content creation

4) Servers

5) Embedded Devices such as Routers that have only a remote Web/HTML gui

6) TVs & Setboxes with only a simple remote control.

Strangely GNU-Linux can do all of these. Possibly because historically it was worst at (3). Today there is nothing wrong with GNU-Linux desktop, except possibly for Ubuntu Unity. But unlike Win8 on Ubuntu you can easily swap the desktop to one of choice. Curiously MS once had this to extent on NT4.0 you could have Program Manager and File Manager instead of Explorer. Replacing Explorer's File Browser Window with File Manager would have been nice, though really the solution is to open two Explorer Windows.

However File copying & Moving in Windows is still rubbish and unreliable for large amounts of files and where some files have various attributes compared to xcopy and other CLI tools.

Re: Ultrasound

Two Ultrasound transmitters that are separated and transmitting different but isochronous codes. (This can be done by "slaving one" off the other via IR link, so one transmitter is "dumb" just using an IR remote sensor driving the Ultrasonic transmitter directly).

A sensor on the robot can calculate the distance from each easily. If the robot is told what side of the line between the Transmitters it's on, it knows it's location. if it has a pair of separated sensors it can use the phase between them to calculate orientation.

Put the two Ultrasound TX at two corners of the boundary.

WTF is... White Space radio networking?

Mage
Silver badge

Re: White Space...WTF?

No, the vacated spectrum is NOT "White space", that's the "Digital Dividend".

So called "White space" is the effect caused by the fact that if C23 for example is used for a Station, it can't be reused at the next city, but at a further city. At the intermediate location you are not ensured any reception on C23. But SOME people may have larger poles and Aerials and get either C23 depending which way it's pointed. The Fantasy of "White Space" radio is the idea that at certain locations you can re-use the in use channel because

a) No-one here is using it.

b) you won't interfere with the further off places that do use it.

Both assumptions are false.
