The following activities are subject to restrictions in the district of Stevenage: Drive at excessive speed, or otherwise dangerously Driving in convoy Racing against other motor vehicles Performing stunts in or on motor vehicles Sounding horns or playing radios Dropping litter Supplying or using illegal drugs Urinating in public Shouting or abusing, threatening, or otherwise intimidating another person Obstruction of any other road user 1 Link to post Share on other sites More sharing options...

I mean, introduce full autopilot into a car and what's stopping the driver having a snooze or reading a book instead of paying attention. Bad enough people already mess about with phones and do their makeup behind the wheel. You could test that theory by looking at aviation. in 25 years computers have gradually increased their role exponentially to todays modern cockpit which is mostly automated.

KeithMacdonald Posted July 22 Share Posted July 22 Quote In the YouTube video below, retired software engineer and Windows developer Dave explains the cause of the recent CrowdStrike IT outage. Dave discusses the significance of CrowdStrike being on machines in the first place and the consequences of a kernel driver failure. He also shares his experience as a Microsoft developer in the 1990s and the importance of understanding the differences between kernel mode and user mode. He then delves into the concept of kernel mode and user mode, explaining that only a few things, such as thread scheduling, Heap manager, and device drivers, run in kernel mode due to its access to hardware. 1 Link to post Share on other sites More sharing options...
GrumpyPenguin Posted July 22 Share Posted July 22 I had never heard of Crowdstrike before this current issue. I don't watch overpaid people drive similary powered computers with four wheels chasing each other round & round either so why would I know about Crowdstrike. 2 Link to post Share on other sites More sharing options...

You can lock NT down at least as much as Linux but most Windows users will scream and throw their computer out of the window rather than put up with it. Hello, I'm afraid that I can't agree that Windows NT based systems can be as secure as a Linux system, the fundamental design of Linux ensures that it is virtually impossible for malware to do any system wide damage (anti virus/ malware software is very much an optional extra on Linux but is essential on Windows). When combined with all the tools that Linux has "out of the box" (eg SELinux), system security is much better. Even if you could add all these levels of security to a Windows system it would be unusable. My basic point is that Windows is fundamentally flawed (from a security point of view) by bad design/implementation decisions taken many years ago whereas Linux/Unix systems were designed to be multiuser and networked from the start. If you accept that proposition then there would be no Crowdstrike to create problems if the systems had been designed differently. As an aside, I'm a computer scientist (well computational biologist) and my research career began on VMS machines and I think a lot of their much vaunted security was due to how obscure it was to manage and use them ! Nice to hear that you're a VMS person too, I've got a collection of VAX and Alpha VMS machines (along with SGIs and Sun's etc) that I saved from skips when universities threw them out that I like to play with every so often, useful for teaching too.

RMweb Premium jjb1970 Posted July 23 RMweb Premium Share Posted July 23 Consumers embraced computers when they became a tool which didn't require expertise to use. Most people aren't interested in computers, they're interested in the services they provide. Many years ago I read an article which compared computers with electric motors. Few people want or buy an electric motor, most want the functionality provided by a machine powered by an electric motor. People want to use the Web, apps, do word processing, digital imaging, content creation etc. For most a computer is a tool, how it works is not their interest no more than a typical airline passenger understands how aeroplanes and engines work or a typical driver really understands what's under the skin of their car. In that context it's entirely understandable why typical users just buy commercially available devices using Windows, Android or Apple alternatives. 6 1 Link to post Share on other sites More sharing options...

My basic point is that Windows is fundamentally flawed (from a security point of view) by bad design/implementation decisions taken many years ago whereas Linux/Unix systems were designed to be multiuser and networked from the start. Firstly Windows NT was (as my post indicated) designed to be a secure, multi-user system from the start the same as Linux was. Secondly Linux is not immune to malware. A significant reason for the relative lack of malware has been lack of interest by the attackers. Most attackers are (or have been until relatively recently) been attacking 'users' and as a niche operating system Linux just didn't make for a juicy target. As that article says such attacks are rapidly increasing likely due to the move toward the cloud. But the problem with Windows these days is the basic dichotomy between usability and security. Some of that is due to the nature of ecosystem that Microsoft has fostered. Users are used to being able to do anything they want with their computer and dislike being nannied. They also dislike having to understand how their computer works. Windows can be configured to be a lot more secure and in the hands of a knowledgeable and sensible person is a very low risk environment. Unfortunately that doesn't suit most of its customer base. So it depends whether you consider that to be a fault of the OS or not. I don't. I blame the users rather than the OS. Link to post Share on other sites More sharing options...
DY444 Posted July 23 Share Posted July 23 Fairly predictable that this has descended into the usual ios/linux good, windows bad partisan pile on from enthusiasts of IBM (Imperative to Blame Microsoft). Blaming Microsoft for the consequence of applications run on its OS is like blaming a car manufacturer when bad driving causes a crash of one of its vehicles. As to the "windows shouldn't allow it" argument, it is being widely reported today that the EU forced MS to make the windows kernel more accessible to third party vendors thus preventing a tight policing of its use. If MS had defied the EU then two things would have happened; it would have been heavily fined and the self-same IBM enthusiasts would have piled on about law breaking and abuse of market position. No. This issue is down to CrowdStrike's unbelievable incompetence in pushing out this fatally flawed update and a regulatory environment that allowed them to be in a position to do so. 1 5 Link to post Share on other sites More sharing options...

You can lock NT down at least as much as Linux but most Windows users will scream and throw their computer out of the window rather than put up with it. I recall the Windows 2000 / ME era. I upgraded my home PC from 98 to 2000, so from the 9x architecture to NT. I loved Windows 2000, it didn't have the fancy toys and funkyness of ME, but ME was an unstable POS. 2000 could stay booted for days with minimal impact. Most decent games still worked on 2000 fine, and it just felt like a more solid system. ME required regular reboots and was stuck with <512mb memory. Look where we are now, the NT based system developed further and 9x rightfully went the way of the Dodo. I'm not a dev, sysadmin or otherwise, just a support guy who likes gaming, but I thought 2000 was streets ahead of its ME 'successor'. 2 Link to post Share on other sites More sharing options...

RMweb Gold AndrueC Posted July 23 RMweb Gold Share Posted July 23 Windows has the potential to be more secure through more draconian configuration although the constant trickle of bug reports is concerning and begs questions about Microsoft developer's skills. The repeated bugs introduced through updates is more worrying and begs further questions about their QA skills. To be fair a lot of security issues relate to applications rather than the OS but are in some case allowed to become a problem because the OS has to retain compatibility and allow things it perhaps shouldn't. 2 hours ago, GrumpyPenguin said: If everyone was running Linux like we run Windows then you could be sure that the hackers would be targeting it For me that's at the heart of the debate. What would it be like if Linux displaced Windows. Could it displace it? My feeling is that Linux is just not compatible with the 'common user' ecosystem we have today. Either Linux would have to change to become more like Windows or else the average user would have to become more technically aware and more sensible. The first is possible but would be a technology crime. The second I fear is never going to happen. My conclusion is: Windows is not a bad operating system. It's actually a pretty good one and certainly one that is 'good enough' for the markets it serves. 1 Link to post Share on other sites More sharing options...

The systems generically known as TCAS provides a warning to the flight crew, they then act upon the warning. My understanding is that the Automatic Pilot will obey a TCAS Resolution Advisory if Automatic Pilot is engaged. This would usually be the case for most of a long-haul flight - the boring bit when the pilots might as well be reading a book. Though they would be expected to put their book down if TCAS or any other monitoring systems suddenly starts shouting at them! The crew would have to react if it were not engaged (more likely at take-off/landing) . And of course only larger airliners are fitted with these systems - light aircraft typically don't have TCAS, but can of course present a collision risk to bigger aircraft. TCAS should be still able to detect such aircraft as long as they are fitted with working transponders. 1 Link to post Share on other sites More sharing options...
RMweb Premium MJI Posted July 25 RMweb Premium Share Posted July 25 Windows problems is that they keep fiddling with the UI, and forcing their own choices. My work PC changed itself to 11 and getting it half usable was a nightmare, stuck with a worse version of notepad, and paint. And THREE different styles of scroll bars all looking different. 10 was not bad, but no 7. 2000 to 7 was the high spot of MS Windows, to be honest the main use for it is running anything WIN32 or WIN64. Anyway it drove me so mad I put Linux Mint onto a new PC, and it runs lovely. I did put a 10VM on as well, for those odd programs WINE will not cope with, or the Linux version will just not install (Chitubox), but it is locked down, no updates, VirtualBox configured to show not trusted boot. And does not need the internet. 2 Link to post Share on other sites More sharing options...
