Re: I'm too lazy to downvote all the sonar/ultrasonic rangefinder commentards

No difficulty in demodulation of PSK on a 40kHz narrowband carrier. Not a huge o/p from lawnmower at that frequency. 40KHz and 60kHz has been used in extremely noisy environments.

The data rate doesn't need to be high which lowers the SNR needed.

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.

In the 1960s

There was a Hobbit Restaurant in Belfast. I think it was still there in the 1980s. Not really been there since 1983 so no idea if it's still there. I was never in it but I bet they served good 2nd and 3rd Breakfasts though.

Anything a major part of culture should be available under FRAND, like patents incorporated in Standards. Apart from Apple, and occasionally Microsoft and Oracle that works. It's not like these people are a National Franchise. IMO the "loyalty card" is a step too far without talking to the Film company first. Anyone think £200 a year would be reasonable and no photos / images directly from the films or book illustrations?

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.

Re: I have my doubts

3G networks use dedicated licensed spectrum Each operator plans their own spectrum, or with a RAN the Network Manager manages the Pooled spectrum.

The Spectrum isn't shared with a Broadcast service. So called "white space" is an illusion.

The "Database" is a clumsy attempt to solve the "hidden transmitter syndrome". Just because this sounds cool, or allows licence free kit or is very clever doesn't make it a good idea.

SFN

You can't do very large regions with SFN. Go read how it works. The difference of arrival of signal from two transmissions can't exceed symbol guard time.

SFN doesn't enable so called "White space". It just simplifies planning at some locations.

It's a fantasy that will damage TV reception for 100,000s of people.

An evil genie that should never be let out of the box. Apart from the fact that even if done as planned it's a disaster of epic proportions, people will disable the geo database lookup, the data base will be inadequate and people will add too powerful aerials or amplifiers.

We don't need this Yuppie DIY outdoor WiFi. Proper protected dedicated Licensed Spectrum is the only solution that works.

Most of Apple's patent's are either fluff or else really Registered Design (more about Copyright, look and Fell) rather than real engineering as most (all) of the products use no custom parts beyond the case (The Apple CPU is just a variant of Samsung SoC with ARM core).

HD?

1920 x 1200 may be HD on a 24" TV screen but not on Computer.

You need roughly 3000 x 1700 pixels for a 24" Widescreen to have the resolution of 1600 x 1200 15.4" screens ten years ago.

Nice product though. But a trifle pricey for a low resolution computer monitor and resistive panel, though of course it's a bit more than both.

Tick-like banking Trojan drills into Firefox, sucks out info

Re: Correction - firefox on MS's rubbish OS's

You are making assumption that the user doesn't install something that carries this.

Also it uses remote configuration, so likely needs no write access once the user has installed whatever carries it. Assuming it's really a Trojan in original SW sense of the word.

A wasteful pointless gimmick. Probably creates interference too.

What is wrong with

a) A dock (look at DECT phones and most Handheld two way radios)

or

b) Micro USB or mini USB

Unless it's Fixed ...

Nomadic / mobile / indoor / self install on 3.5GHz is rubbish. Only fixed outdoor/roof aerials makes sense.

Google Imagine WiMax and IBB Ripwave.

LTE doesn't fix the problem.

http://www.radioway.info/comparewireless/

Indoor aerials about x8 less capacity / speed than roof top fixed directional aerials.

Really Fixed Wimax or WiDox (DOCSIS over Wireless) makes more sense at 3.5GHz. So either they are clueless or selling self install "nomadic" "windowsill" kit to save on roll out cost.

Bad investment, bad decision.

More proof, not that we need any

All this was designed and discussed 30 years ago.

We called it Gesture based GUI.

The Patents system is obviously broken. Explain to me how much R&D effort there is in this compared with the effort of drawing up the so called "patent"

Apple spends 2% on R&D. How much of that time is spent advising the Patent guys and how much does Apple spend on Patent Paper work?

Death to Office or to Windows - choose wisely, Microsoft

MS Office isn't important

Libre office (the more popular fork of Open Office) now has Intel backing it and for 99.99% people is good enough.

OK I made up the statistic. But seriously iPad doesn't need Office to Succeed and really there are loads of reason to want Windows on a Laptop/Desktop (hardly any on a Tablet and none on a phone), But MS Office is now WAY down the list of reasons.

Lantronix xPrintServer

Mage

But ...

Why doesn't it have a USB port for a printer?

Or did I miss that?

I have Network Printer servers here. They have connections to drive a printer.

My E65 phone via WiFi can print to any printer on the Network configured to appear as LPR. No extra boxes needed. Of course with the "stock" printer driver I have to emulate an HP laser too.

I can make any linux thing (my Router's USB port) or USB, Serial, Parallel make almost the stupidest printer look like a Postcript LPR device. If I'm really in the mood I can do it on NT4 (even for USB via 3rd party USB stack, but parallel is trivial), Win2000, XP or Win7 too.

So why spend £115 to achieve what almost anything you already have that talks to a printer can do for free?

Or what did I not understand?

1500 lines

For 11.6" long document at 133dpI, you need more than 1500 lines.

Widescreen makes 15" screens too poor on vertical. We need 4 x 3 or even square screens.

The obsession with video is really annoying. Besides most cinema is actually NOT 16:9

To replace a 15.5" approx 1600 x 1200 ten year old 4:3 laptop you now need an 18" machine. Crazy.

Ultrabooks/macair/Ultrathin are a pointless luxury format.

An NT-powered Windows Phone? Not so fast...

Mage

Alert

NT3.51 vs NT4.0

In high reliability situations the NT3.51 lived on quite a while after NT4.0. They blew stability for a measly 10% increase in video & game performance. Yet it wasn't until XP that most games really used NT rather than the Win9x platform.

Since Printer Drivers use GDI also and sort of emulate a graphics surface on NT4.0 a bad printer driver could "BSOD" your workstation or Server. Impossible on NT3.1 to NT3.51.

Ironically the WHOLE NT3.1 was release about the same time as ONLY the kernel of GNU/Linux, I think in 1993.

Why NT3.51? Well, MS "invented" largely fake APIs so Win95 Apps wouldn't run on WFWG3.11 (some only really 16bit). In reality WFWG3.11 had 32bit TCP/IP, 32bit Diskmanager option and Win32s to run NT applications (no named pipe creation was only significant lack).

So they had to add these to NT3.5 and give many a free upgrade to NT3.51. Oh, no version of win9x could create named Pipes either. Win95a little more than all the 32bit options for WFWG3.11 with the Explorer shell.

NT4.0 could use Program Manager and Filemanager and there was a "Technology preview" Explorer shell for NT3.51.

I think Win CE was more a cut down NT with very limited thread/process space (a fixed number) done for a Sega console, and not based on WFWG3.11/Win9x. It was designed for very limited memory with no paging, hence small fixed resource limits rather than dynamic structures. The main stupidity of WinCE PDAs and Phones was using a miniature version of the Windows interface instead of something designed for a small screen. 320 x 240 was a LARGE win CE screen for a long time!

ARM rains on x86 as smartphones outship PCs

Mage

Alert

StrongARM

It came from Digital Equipment Corp as part payment in a patent spat.

After a little development they sold most of the ARM stuff to Marvel, though kept a comms SOC with ARM core.

So I wouldn't say they were ever very keen. Their own i960 RISC controller was popular once, but Intel failed to develop it sensibly and do good SOC.

Part of the success of ARM is that it's usually just a small part of an SOC. Even 4 or 5 years ago an ARM SoC might have had the equivalent I/O of an entire laptop motherboard. I used the Samsung 6400 SOC before iPhone and it has the Flash and RAM chips stacked on the ARM SoC all in a 3mm high package. So no Flash or RAM PCB traces or PCB footprint. Intel still don't have an SoC with all the I/O of that part (inc Graphics) low enough power to stack even one other chip on top.
