If you wanna make your own open-source chip, just Google it. Literally. Web giant says it'll fab them for free

If you use low powered IR leds and IR camera eye tracking becomes a lot easier as the iris shows up better . Just need to make sure the eye does not heat up too much. This was the basis of an eye tracking system used in the early 90's in the R&D department I worked in at the time. It worked quite well except the issue around the eye feeling slightly warmer.

Re: @bazza - @martinusher - It's not an OS

You missed the announcement from Lenovo about first line support for Linux preinstalled with upstreaming of all of the drivers.

Just saying... Kernel updates require a reboot.

Everything OK with Microsoft? Windows giant admits it was 'on the wrong side of history' with regard to open source

It's the 'not invented here' and 'nobody will pay for the open source we are using' philosophy of senior and middle managers. Personally you are paying for my time. If I can get the job done quicker and cheaper by using open source I will use it (as long as the licence permits me too)... especially as it will give me more time to spend on the value part of the project rather than reinventing the wheel yet again...

Re: Disappointingly

I've used my low light 48mega pixel phone camera with an attachment to fit on my telescope. I've had some really stunning photos as good as those using SLR cameras fitted to the same telescope. Only issue is light bleed around the edges but that's easy to fix.

It was cheaper to buy a mesh system then get halo 2 from BT.

The point of containers is they aren't VMs, yet Microsoft licenses SQL Server in containers as if they were VMs

Re: Licencing is easy

Or you pay for a postgres developer fulltime to work for you on postgres and then ask oracle for a very deep discount because look you can jump ship anytime you want too... Know a company that's doing this....

Collabora working on making any DirectX 12 driver able to support open graphics and parallel programming APIs

Re: back in the 90's when DirectX first became "a thing"

M$ also pushed Direct2D as a replacement for GDI... Took ages to convince management it was a lost cause. We ended up producing a modern OpenGL/ES rendering engine. We never did a DirectX engine as it was wasted effort as the OpenGL drivers are good enough from Intel/AMD/Nvidia on Windows.

Re: On the cheap

NoMachine... If you install was free last time I installed. Commercial is reasonable.

damiandixon

NoMachine is a decent option

It's fast... Works on Windows and Linux.

OpenGL/DirectX work.

Low bandwidth. Hardware compression supported.

Your desktop is as if you logged in, unlike RD.

However if you do RD in on Windows hardware acceleration of 3D gets disabled and you have to physically login.

IMHO it's a decent option to access a work machine remotely especially if you use apps that use OpenGL/DirectX/Vulcan...

Use our stuff for free and sell your application? That's Qt. Time to give something back

damiandixon

The cost of the commercial licence for small projects/companies was prohibitive especially if you are just using Qt for the GUI. Just compare the cost against Visual studio on a yearly basis...

damiandixon

Some libraries, especially in QML, are now only GPL when you use the OSS version.

Makes it painful to ensure compliance with LGPL.

I'm sure its been done on purpose in an attempt to sell commercial licences.

Re: Licence

QT OpenSource Licence is pretty much LGPL. Some libraries or parts are GPL but these can be avoided if you carefully review what you are using. Most of the GPL issue is around QML libraries.

Mostly its fud from the current company developing QT in an attempt to get people to pay quite a lot of money.

Better insulation standards would bring down the heat generation capacity of a boiler.

However builders keep lobbying against better build standards for insulation, energy saving and energy reduction.

Re: Eh?

I run clamav on my NAS box (running Linux) and some of my linux boxes as they provide backup space for my windows boxes... So far I've only picked up viruses from email backup and backups of Windows boxes.

OpenGL implementation status & personal experience

Personally I've had way too many problems with the nouveau drivers to even consider using them. I've still got one laptop that I need to sort out after an upgrade where everything points to this driver. I just can't get the desktop to start. Really need to find the time to do a backup and clean install.

I'm having no issues with the i965 drivers with Mesa on my fallback laptop.

I use the NVIDIA drivers on Linux when I need to do GPU debugging and performance analysis.

The following is a great site to see the state of Mesa support for OpenGL version and the different drivers:

Any professional programmer will test on all the supported targets. If you have set up your build & test system correctly then the overhead should not be unmanageable.

When I did development for Java I also test on the target JVM (developed on the Sun/Oracle JVM, deployed on the IBM z/OS JVM with some interesting bugs too).

Hello 'WOS': Windows on Arm now has a price

Re: Intel sueing in 3... 2... 1...

Almost everything I compile is targeted at i5 or newer running Windows 7 SP1 or newer (ignoring Windows 8/8.1) depending on what the customer asks for. If they want something older or a different processor it costs extra.

damiandixon

Re: How much?

Picked myself up a returned Dell Inspiron 13 a couple of months back for ~£230. Usual price is > £500.

The laptop has a touch screen, tablet mode, full windows 10, 1TB drive, 4GB of memory. Absolutly nothing wrong with it at all. Did not look like it had even been turned on.

Installed Ubuntu on half the disk, as I need both OS's. I manly needed the laptop for testing software with an Intel GPU.

Ubuntu runs well. Windows not so well.

Chrome on both struggle after you have 5 or 6 tabs open.

Could do with at least 8GB of memory though!

Eight months after Equifax megahack, some Brits are only just being notified

damiandixon

Who was the data collated for

Having had my fingers burnt with this one I would like to know who the data was collated for.

So far Equifax has been very quiet on this.

The identity monitoring tool of thiers is not particularly good. It keeps emailing me to tell me that its found something. I'm reluctant to sign up for the more intrusive monitoring as you have to give them even more personal information and given that they have already lost a load of personal information it does not bode well for trusting them to keep the data safe.

Busted Windows 8, 10 update blamed for breaking Brits' DHCP

Re: Use Google DNS

I believe I never said that DHCP had anything to do with DNS.

You do however get your DNS setup via DHCP unless you set your DNS addresses locally.

damiandixon

DHCP and DNS may be the issue

I had a neighbour with this problem last weekend.

They had been sent a replacement router from BT but still had problems.

I changed their Windows 10 PC to use google's DNS servers and everything started working again.

All my windows PC's use fixed DNS servers and I've not run into this problem so far.

I've not had any real issues with my HH4 and FTTC. The only real issue I have with the HH4 is the complete lack of being able to configure them to my liking, such as pointing at a set of DNS servers that are not BTs. Any suggestions?

damiandixon

Re: Use Google DNS

I've been using Google's DNS on all my Windows PCs at home for ages.

I've been changing my neighbours to use Google DNS when they have been having connection issues.

My first assumption was a DNS server issue at BT.
