"The article explains why this is a bad idea"
James Burke's Connections explained a failover system of the electrical grid in America. One relay tripped because a street was overloaded and it passed the current over to other circuits in a domino effect until the whole state was offline.
If the load is too much for one then it will be too much when added to the next one that's still working.
Re: Giving the vendors a choice will give the users a choice
Most routers do state they are GPL so it should be possible to change the firmware on them. What the makers don't do is keep the hardware of a model consistent meaning you could buy two routers of the same model in the same week with radically different hardware. Not much help if you're trying to build something.
If you really want control of your router then buy a Mikrotik and learn how to configure it.
Re: "Support for open firmware is, arguably, a niche consideration at the moment"
I was a big user and supporter of DD-WRT which is a user friendly take on OpenWRT. However TP-Link routers now contain most of the bits I was using in DD-WRT.
DD-WRT was a replacement for Linksys WRT54GS firmware but an arms race ensued where each hardware release from Linksys would seek to stop people installing DD-WRT.
There are loads of cheap routers that will accept DD-WRT but the last two versions on the TP-Link I use does not accept it. I don't think TP-Link have anything against DD-WRT just that they changed to a cheaper chipset. DD-WRT does support this chipset but someone has to create the version for this router.
Not such a big demand from me for this as the TP-Link does all I want like;
AP Router Mode
Range Extender Mode
which was my initial reason for using DD-WRT in the first place.
As for VPN you really need a more powerful router since these little ones can't do VPN at current high bandwidths.
Exactly, it should be the consequences that the punishment are based on. I suspect that if they had time to chase the drone then the more important job of finding the missing person had been successful. However if they abandoned the search in order to make £460 they have their priorities wrong.
Re: “Oh look, there's a drone”
The police do have a terrible record for air safety. They are supposed to have the pilot concentrate on flying and the policeman concentrate on spotting. Once the pilot joins the search they're in great danger.
If the pilot really did give chase to the drone he would need fighter pilot skills. "Tank I need a fighter pilot program for an EC145 helicopter"
Re: This is good.
Passive Power over Ethernet would make the PI easier to use. You don't need that 48v nightmare. Most home routers run off a 12v PSU and have a little buck circuit to bring it down to 5v. These are very sturdy little circuits allowing 7v to 27v power. The advantage against 5v power is you can run some very long wires such as PoE. Many times I have powered 12v routers over Ethernet with no problems. You simply can't do that with 5v because there is no tolerance for volt drop.
I appreciate why the PI runs off 5v and does not have one of these 12v buck circuits. If there were a way to include a sturdy buck circuit as a hat with options for passive PoE, plug connector and screw terminals then it would mean putting PI in industrial locations much easier. Frankly 5v power is too flaky. With the right capacitors the buck circuit could handle 30v.
Re: Downgrade attack?
Whitepines, that is a good point. People always assume the attack will happen once the machine goes live but tinkering with it before it's delivered would be a powerful attack. We recently had questions about the security of Supermicro machines because they are Chinese. This then changed into someone adding tiny chips to the motherboard. That whole business seemed odd but it did expose the idea that the machines could have been altered on route to the customer.
I think proper physical security of the packaging would help but then the route in would be a customs inspection. Just boot the machines to a a USB stick and insert the firmware changes.
I'm not sure how reliable that would be as a compromise since most people grab the latest firmware before installing the OS. I'm not sure if microcode stays in the CPU or is loaded at boot time. It's obviously the sort of thing very security conscious people would know to check and ordinary computer builders would never think of.
Re: Deinstall parts of W10? Gaming on Mint 19 Steam
Linux gaming took a massive leap forward when Steam included a version of WINE called Proton. I've built a RYZEN system with a decent AMD GPU and installed the latest AMDGPU-PRO which uses Vulkan, the driver which will solve all the Linux gaming problems one day.
Re: I don't...
"I'm surprised Zuckerberg is still even there. With all that money I'd just get out while you still can before it all comes crashing down like MySpace. And I just couldn't be arsed with the aggro. But then that's probably also why I'd never succeed in business.
Exactly. You've gotta be a bit power hungry to want to keep doing that work.
I think the current big boys are arranging legislation to prevent upstarts and so they can carry on with impunity no matter how crap they become.
Deleting FB account is not as easy as you think. Just as deleting a file is really just de-listing it from the directory it's the same with FB. Then when you finally want to scrub it off their system they are suddenly unsure it's really you and need you to register your phone and other methods of ID.
That scary old system with 'do not touch' on it? Your boss very much wants you to touch it. Now what do you do?
Mirroring is looking backwards
If you're going to build a new system don't expect it to produce the same results as the old one. What would be the point?
The new system should be built in stages but those stages must be significant enough to actually do something that's an improvement. If the stage is too small it will fail. It has to be big enough to stand on it's own but small enough that it can be managed.
Let's say you are migrating to Linux, you would first migrate to cross platform programs. Then the move to Linux is just a change of OS.
Re: Drivers ?
I thank that's a fair assumption. If it's aimed at the server market then having network ports is the top requirement. If they use any of the existing network chips then the drivers are already written.
I think if you're not sure what you will use this server for then there is some concern that there is something it might not do. If the only way you can do the job is by running Windows Server then you've bought the wrong hardware. Same would go for running Windows VMs. However if it can be done on Linux then this can do it.
I suspect the only thing stopping people choosing these is lack of experience with non-x86 CPUs. Anyone who has used a Raspberry PI as a server will be quite confident to use this to scale up the project.
I was working in a corporation in the 1990's and they switched from Lotus Notes which the users were very good at creating business apps to MS Outlook and Exchange which could not seem to do much with themselves.
I was puzzled at the time why they did this and I am convinced it was just some sort of corporate conspiracy to get rid of Lotus from the computer industry.
Same sort of thing happened with Flash. Web developers loved it and users enjoyed the fancy animations but no we have to get rid of it, along with wolf whistling and proper light bulbs.
Re: switched from analogue to digital computers 70 years ago
I did some work on a huge machine that converted movie film into video. It was a complex digital and analogue computer. The machine was decades old but still in use because the job could not be handled digitally in 1998 (according to the machine's owner).
Re: So... who pays for the 3G/4G data connection?
" If you don't then holding title to the vehicle is not worth the paper it is written on."
You don't hold the title to the vehicle. The 'log book' document specifically says THIS IS NOT PROOF OF OWNERSHIP. The DVLA own your vehicle, you are simply the keeper and the driver. Driving is illegal which is why the DVLA have to sell you a licence.
