I ask this question every time and I will ask it again. Produce some packet captures of Chrome exhibiting this behavior. I'm waiting.
I can do that for Windows 10 even after I have opted out of the so-called "help"?? features. How can anyone trust an operating system that can spy on them?
I have never had a problem with Chrome (it's easy to turn off tracking if you want) or any of the other web browsers (e. Firefox, QupZilla, Konqueror) I use.
Laptops can be problematic with Linux distributions and it is always a good idea to do a search to confirm the Linux distribution will work. I personally have found HP laptops do work although I would still recommend a check. A base desktop (check your graphics card compatibility though) will normally run Linux but it does not hurt to check.
It should go without saying but please image or backup your laptop first. I strongly suggest replacing the disk if you are unsure and even if you get a cheap 120GB SSD you will find that your operating system will take up less then 8GB of data (allocate 30GB to 40GB though) and that will allow you about 80GB to 90GB of user filesystem. Even a 240GB SSD is not that much more expensive and you will get blazing speeds.
Once you have confirmed your particular laptop will run a Linux distribution get a LIVE version on a USB stick or CD-ROM and boot off it. If it boots and brings up the particular window (ie. Gnome, KDE, Xfce,... etc) manager and run any tests that you require. Only after you are confident that all tests work then you can install.
Installation (assuming no dual boot which I don't recommend) of most Linux distributions especially if you just accept the defaults should take less then twenty minutes.
My Desktop supports 7.1 sound although I only have a 2.1 sound system which if I turn it up will annoy my wife and neighbors. My motherboard supports up to 4K and I have tested it with a 1440p monitor without any issues.
If you are really into the latest games then please ignore what I have said and stick to MS Windows. There are over 5,000 games (see Steam) that will run natively under Linux but they are usually not the latest games. Anyway, I have a PS4 and a backward compatibility PS3 for games so that is not an issue for me.
I run Fedora (latest is 27) however I don't recommend that distribution for novice Linux users although I have not had any issues with it for over three years (Fedora 22) and even then the issues I had were minor. I even have Fedora 26 on an eleven year old HP laptop although it chugs when playing H265 video (H264 is fine). A good distribution for the novice upwards is Mint. If you have a problem or question check out the appropriate forums they are all very good.
"I'll be installing Linux when I have a week of downtime."
And that is precisely why Linux isn't a good desktop OS.
Time to upgrade from Fedora 26 to Fedora 27 for me was about an hour and I actually do an install upgrade since that gets rid of any rubbish that I have not documented. People document their important desktop requirements - don't they?
Of course, I could do an update process which takes less time and is easier but since I do install some programmes for testing purposes a fresh install does get rid of them unless I have documented that I wish to keep them.
If you take more than three hours to do an upgrade and most of the time you are waiting then you are doing something wrong. Even a fresh install should take no more than one hour (normally about 20 minutes if you use the automatic install and that includes distributions like Mint as well).
So I spend about one to one and half hours every half year on an upgrade is that a problem? I do backup but rarely have to go through a recovery since I don't reformat my data filesystems when doing an install upgrade although I do reformat all system filesystems.
It should be noted that even the stable version of Fedora distribution is not really for the novice since you will be basically on the dull bleeding edge but that said it is still a very good distribution. I would recommend waiting at least a week before installing/upgrading to the latest version unless you are confident in your abilities, although for the last six releases I have not had any issues and issues prior to that have normally been minor.

I fully agree with what you said since my mother suffered from Alzheimer's. Still, she was fairly fit up until her death.
What is interesting is that Bill Gates (born 1955) is now 62 years of age and as you get older the chances of getting some sort of dementia increases. In fact, the reference I provided makes the following statement "Starting at age 65, the risk of developing the disease doubles every 5 years."
Of course, Bill Gates could be unselfish and I do commend him for the donation although I really do have to ask why did he wait for so long?
I already have 4.13.10-200 which was from a Fedora 26 update on the 3rd November 2017 (Australian time zone).

4.13.11-200.fc26.x86_64 #1 SMP Thu Nov 2 18:28:35 UTC 2017
It must be noted that I am running the stable version of Fedora 26 not the developer's version, however, I do have a tenancy to get a new incremental release of the kernel once a week as part of the normal update process.
Of course like most Linux distribution updates I have the choice of a graphical update or command line update or a combination and except for initializing the update process (I could automate the process if I wish) I have full control as to when I reboot (kernel updates only) which only takes about a minute (SSD's are great).
BTW. If you don't have the 4.13 kernel then you will have to wait for your distribution maintainer to make it available in the repository or you could download (not recommended unless you know what you are doing) it and install it.
Your argument would be a little more persuasive if you expressed it using correct English grammar.
Which English? UK English or US English?
If you wish to correct my grammar then fine but please point out where my grammar is incorrect and why so I may learn from what I have incorrectly said.
That percentage was the average for the number of rocket launches for the world. So far Elon Musk has done ok but there may be problems ahead with his proposal for heavy lifting items into orbit. So far Space X has had 10 successful launches of their Falcon 9 rockets.
No, I don't hate Elon Musk since I don't know him, all I am interested in is feasibility and not hype. If I am wrong then fine I don't mind and I have learned something new but just believing the hype without valid evidence is plain stupid.
Of course by then you'll insist that, even though Hyperloop turned out to work after all and the BFR seems to take off and land like clockwork, everything else that will be in the pipeline at that point will be bound to fail because it can't possibly work
See there you go jumping to conclusions. Where is your evidence for what you just said? I personally don't have any evidence for success or failure although I have pointed out concerns. So far you seem to think that everything is going to work fine. I am sorry but science is not in the business of miracles otherwise we would all have jetpacks and flying cars by now.
Well, he's still as annoyingly smug as when he first started laughing at the idea. I find it slightly amusing that he's seemingly unaware of the irony of pooh-poohing the idea of hyperloop while mocking the Kitty Hawk comparison.
There is a huge difference between heavier than air flight by the Wright Brothers and the so-called Hyperloop proposal. For starter people like Leonardo da Vinci (1452 to 1519) knew about flight structures well before the first powered flight. From then on aircraft developed quickly and surprisingly the Wright Brothers never got any patent money from it.
When discussing a vacuum container at sea level the pressure on the container will be one atmosphere which is 101kPa or 15psi and not equivalent to 10 meters of water. Sure a decently prepared vacuum container will be able to take these pressures but what has been proposed is a vacuum tube that is well over 100km long and is capable of taking a shuttle or multiple shuttles with human passengers that are supposed to be traveling at around 1100kph (700mph) and all it takes is a minor fault or rupture and you have human salsa. It must be noted that no country in the world has ever come close or has even considered what has been proposed.
"Modern engineer solutions turn the miraculous into the mundane?" If you look at electronics then sort of yes but I was using computers with decent graphics back in 1983 and while computers have got more powerful and smaller they still have not changed that significantly since the 1980's. Do you know that in the late 1950's the worlds first hovercar was built Curtiss-Wright Model 2500 Air Car however even today I don't see any hover or flying cars on the road. You can even look at the Concord and I will leave it up to you to find out why we don't have supersonic passenger jets anymore.
As an Engineer, I am all for science and advancement but I also like to see the evidence (you know the Scientific Method) before I agree or disagree. Jumping on-board for the hype is plain stupid and can be expensive.
As for annoyingly smug, I don't find Thunderfoot that way since he always provides evidence and that is what I care about.
OK, you're an EE with 35 yrs of experience, and Elon Musk is a real-world Tony Stark who builds rockets and electric cars. I choose not to underestimate Mr Musk / Stark.
Oh, I am still waiting for my flying car or cost-effective jetpack.
It's very easy to compare Elon Musk to Tony Stark but I have yet to see a flying suit that can take a hit from the Hulk much less fly at Mach speed. Yes, Elon Musk has got his Engineers to build the Tesla electric car which is not that cheap although I will admit it does have an EPA-rated range of 335 miles (540 km) on a full charge compared to other electric cars which have half that range but at a third of the price.
Yes, rockets are great but they are expensive and not that reliable (about 92%) however I notice that Elon Musk's rockets have yet to be manned. I am discounting Space X since that did not achieve orbital velocity.
Therein lies the problem when confronted by hype if you are a sub-professional, professional or a scientist you should always choose not to believe until you can see the evidence. In fact the more hype (especially on media) the more skeptical you should be. There is a saying "If something sounds too good to be true it most likely is". Taking all into account I chose not to overestimate Elon Musk.
C'mon, the "landing fuel" is miniscule since the great mass of the rocket at launch is the "lift fuel" which is gone after the rocket does its primary function. The thing that lands is a hollow, comparatively lightweight tube requiring a slight amount of fuel to accomplish the landing.
Really. Have you done the calculations?
Here is a fairly simple calculation to reach the international space station which is 408 km above the earth. Plugin the number 408 into the Orbit of a satellite Calculator and you will get an Orbital radius of 6,786.14 km, a Flight velocity of 7.66 km/s and an Orbital period 01:32 (Yes I have rounded the numbers).
Now consider you have to get your rocket from an orbital velocity of approximately 7.66 km/s through the Earth's atmosphere which will heat any exposed surface to incandescence and at the same time hoping you have enough fuel to slow the rocket down to a point where it can land tail first. This is not to say it can't be done since it can but the chance of failure is significantly higher than if it landed as the space shuttle did or by parachute.
Yes, I am aware of Elon Musk's proposal for a rocket flight from the US to other countries. It does sound great if you don't think it though hence hype but that type of hype is going to cost ridiculous amounts of money and somehow I think a 10 to 15 hours comfortable flight in a reliable aircraft is not a bad price to pay.
Also while we are considering rocket space flight how about a simple calculation of the "g-forces" on the human body since the so-called rocket plane will have to achieve near orbital velocity while at the same time being careful of fuel consumption. For acceptable human comfort, you would have to allow for 3g (Space shuttle) or less although you could go higher I very much doubt that you would get the average passenger to accept that.
Yes, it does get more complicated but when human lives are at stake I do have a tendency to err on the side of caution and until we develop anti-gravity where a Nobel prize, fame and money is waiting for the first person to develop this, although "cold-fusion" proponents need not apply.
Do you have any Engineering proof that Elon Musk's proposed Hyperloop is feasible? There seems to be a lot of hype and little real Science and Engineering. You know the disciplines that get things done in reality.
I have not looked at the proposed solar battery installation in South Australia but since I am well aware of power systems design and of Elon Musk's hype I think it will most likely be a lemon although I am open to changing my mind. Basically, the SA Government screwed up big time and I am thankful I don't live in that state. When designing an electronic grid everything is up for grabs in the feasibility stage but you also have to be practical and look at the economics as well. Just going solar using photovoltaic cells is plain stupid since you then will have to consider how the store the energy when the sun goes down and batteries just can't cut it at least not economically. Although if you can show an Engineering proof I am amenable to a change of mind.
Landing a rocket tail first? You do know that any rocket can be designed to land tail first it is just not economically viable to do that especially when you consider that the chances of a failure are so much higher than if you came to land like an aircraft or use a parachute. Like it or not rocket flight is expensive and the chance of getting into orbit is reasonably high at 92% but landing is a totally different matter. I will let you research that since us dinosaurs are incapable of using a four-function calculator much less run a Google search.
Personally, I don't mind admitting I am wrong and taking it on board if you can show I am wrong but calling someone a dinosaur and name calling when you don't even know them that is the sort of thing an SJW would say and for your sake I would refrain from saying things like that in the boardroom where us raptors reside.
I still fail to see how this can Hyper-stuff can make a profit. ok, you can move up to 16 people between points at a very fast speed, yet the cars would need to be spaced far enough apart from each other to provide a save emergency stop if something went wrong with car up front.
If the tube was not evacuated then the cars in the tube could be stopped safely which is not that much different to underground trains that many major cities use. The problem you have is the Hyperlink tube is basically a vacuum tube which if ruptured (and it does not take much to do that) will send out a shock wave which would effectively pulverize pretty much all cars in the tube.
Rather than me waffle on try a simple Google search using "hyperloop flaws" and then decide for yourself. Don't believe the hype.
Making a huge rupture in a 1" thick steel tube will require a large quantity of explosives. Such a quantity of explosives won't harm a bus full of passengers unless they're right next to it, in which case everyone could be killed. We don't take that as an argument for eliminating buses.
What makes you think it will be a 2.54cm (1") thick steel pipe. Have you any idea the tech and subsequent cost that would go into making that type of pipe? Not only that but you have to join the pipes with "O" rings (it is a vacuum tube after all) and you also have to take into account the thermal expansion coefficient of steel.
Remember that what has been proposed is a very long vacuum tube so there would be normal air pressure outside so even with a slight deformation you are going to have a rupture which would send out a shockwave traveling at the speed of sound and anything in the tube would be pulverized.
Rather than me waffle on here is a Hyperloop debunked video. There are others on the Hyperloop as well as other popular but impractical pseudo science Snake Oil.
The tech isn't practical, nor will it be preferred to air travel if similarly delayed by security. However the "abandoned tunnels" will become brand new state of the art bunkers for the military.
How can Musk get so much government subsidies? This is how.
But the tech is practical if you have the mind of a troglodyte. What are they teaching people in the schools nowadays can't people detect the Snake Oil?
Okay, I am an Electrical Engineer with well over 35 years experience so what would I know when there is so much pseudo-science associated with the Hyperloop project. No country and I repeat no country has ever built a vacuum tube that even comes close to the length and diameter that is proposed for the Hyperloop when all you need is one rupture in the tube and you have human jelly jam. Snake Oil sale at it's best especially when you consider that the "laughable" Hyperloop test winner was a 200 mph (320kph) electric car that could not carry any passenger since it was too small and did not depend on the vacuum.
Rather than me go into details why the project is stupid please view (there are others) the following YouTube Hyperloop debunk. In case you think the guy is a crackpot he does have a Ph.D. in science but then again human gullibility knows no bounds especially when something sounds attractive (ie. Solar Freaking Roadways) but can be proven by Science and Engineering that they are impractical.
What next for Elon Musk? A proposal for "Tourist trips to mars using cold-fusion powered flying saucers?"
KDE works just fine if you have enough RAM... typically 32G or more
I call BS on that, have you ever run a Linux distribution with KDE?
I run a Linux desktop (Fedora 26 - KDE Spin) which has 16GB of DDR4 RAM and I am not overclocking. I have never once seen memory usage approach 8GB (the average is under 3GB) much less 16GB and I do run many different types of applications over multiple desktops.
In fact, most applications open in less than one second although there are some that do take five seconds (ie. The Gimp), SSD's are great. My system is coming up for its second year and I have the latest Fedora distribution with KDE and I have never had a performance issue.
In addition, I also have a ten-year-old HP Celeron laptop that I use for testing purposes. It has 4GB of memory and it also runs Fedora 26 - KDE spin. I have not noticed any performance issues with regard to KDE but have found that playback of H265 files (H264 is fine) is problematic but that has nothing to do with KDE.
BTW. I prefer KDE's graphical interface to Windows 10's graphical interface.
Logging does not equal security. Logging enables forensic analysis after the fact.
Cameras don't prevent the bank robbery, but they may help you find the robber.
Well said.
The main problem with logs is how long do you keep them. Normally this is set by company policy but as per usual Governments (usually ill-informed or draconian) seem to want companies to keep logs forever which is stupid since logs do take up storage space.
A very import part of company policy with respect to logs is a statement of who has the right to view them and the reasons for this. Obviously, you cannot stop a System Administrator so there has to be some trust but you can dictate that any external access can only be allowed when the appropriate legal documents are produced.
I have noticed many of my friends have laptops that they spent ridiculous amounts of money on and all they do is surf the web. Some have even justified their purchase saying that they need it for work which IMHO is a really stupid reason unless their work subsidises them. Even purchasing Office applications for basic home use is a waste unless you are running a business and even then LibreOffice is usually fine.
I find that a good desktop and a cheap but functional laptop is the best mix of computing hardware but obviously this depends on what you want your computers for and like you have said too many people want to justify their purchase even though they may not be satisfied.
Not sure how true that is - my linux laptop is having all sorts of issues with skylake especially in the power department
My Intel Core i7 Skylake Desktop has never had a problem with Fedora and I built it in December 2015. Now running Fedora 26 KDE spin without any problems and the machine is up 24/7 except when I get a new kernel then a reboot takes about a minute (SSD's are great).
It is important selecting "Other OS" in the BIOS and Fedora works perfectly with UEFI although you can turn it off if your OS does not support it.
BTW. I have a base Skylake Core i7 6700 since I didn't want the "k" (overclock) version and at idle my machine runs at 40W and if I do video translation (ie. Handbrake) it can draw about 80W with my core temperatures getting as high as 70 degrees C although most of the time my core temperatures (there are four cores) range between room temperature and 30 degrees C depending on what I am doing.
2 words. Star Wars. A large chunk of us don't like going to theaters anymore and would stream it if possible.
/ me? Wait till it comes out on DVD// get it from the library/// get a week to watch it.
I think you find that new releases on DVD/Bluray/UHDBluray are going to cost more than a months subscription to Netflix.
You must have a really interesting Library that allows you to borrow (for free) movies.
Well, you do need an hour or two to watch most movies.
A cheaper solution would be to organise with your friends a purchasing and sharing plan which is surprisingly legal until the content providers try to restrict their movies to a registered device. If that becomes the case well all I have to do is feed my green parrot whilst taking the odd swig of rum and singing "Yo Ho Ho".
Of course, if the movie companies take draconian measures to restrict their content then it is perfectly legal for me not to watch their content. Somehow I don't think I am going to miss most of the "rinse repeat" movies that are vomited out every year.
I can't wait to see the Slashdot users to line up to defend this criminal.
I am one person who hopes this guy get the full weight of the law thrown at him since I was one of the people affected by the DDoS attack but in my case, I could see what this scumbag was doing but could not legally do anything.
The actual DDoS attack did not affect my machine although it made any outside communication pretty slow to the point where it was just pointless surfing the WEB. I am not just blaming the idiot (why waste grey matter on remembering his name) but the people who let their PC's be taken over to be used in a botnet and it is not that difficult tracing those infected PC's back to their respective ISP's although it would be difficult do anything about them since some were in different countries including Russa, Germany, Thailand... etc just to name a few.
However, I would never put a Linux in the hands of my mom.
My wife uses Fedora 26 (ie. latest release - took about an hour to install from 25) and she does not have any problems with it.
Yes, I do know that there are people that you should not let within two meters of any electronic device but most people are very capable of running most applications under a Linux distribution although to be proficient in any application you still have to learn it and even if you use Microsoft Windows you still have to learn a particular application either by teaching yourself or getting someone to train you.
The main reason why people use Microsoft Windows is the fact that most PC's (laptops and desktops) are shipped with it (ie. The Microsoft Tax) and most people don't know or care that there are alternatives since it usually is either too hard to grasp or they have locked themselves into a Microsoft ecosystem.
Maybe he is trolling, but he's got a point. In a number of ways, Linux is slowly converging toward Windows, while leaving behind the original Unix philosophy. For ordinary users, Linux in the desktop is making less and less sense, when compared to Windows or Mac.
Take a look at Free/OpenBSD, HP-UX, Solaris and AIX they are all Unix and they all do things differently. Things change over time get used to it.
As for Linux converging towards Microsoft Windows, I think it is the other way around since what I was doing in the early 1980's is not much different from what I do today when using Linux and I was using Windows on Unix (all types) before Microsoft thought it was a good idea. Also having tested Microsoft Windows 10 in a virtual machine I doubt I would trust it with my personal data.

No they run under vi but don't tell Richard that. Now let the flame wars of the 1980's begin again. :-)

Do you know that in the late 1950's the worlds first hovercar was built Curtiss-Wright Model 2500 Air Car however even today I don't see any hover or flying cars on the road. You can even look at the Concord and I will leave it up to you to find out why we don't have supersonic passenger jets anymore.
As an Engineer, I am all for science and advancement but I also like to see the evidence (you know the Scientific Method) before I agree or disagree. Jumping on-board for the hype is plain stupid and can be expensive.
As for annoyingly smug, I don't find Thunderfoot that way since he always provides evidence and that is what I care about.
OK, you're an EE with 35 yrs of experience, and Elon Musk is a real-world Tony Stark who builds rockets and electric cars. I choose not to underestimate Mr Musk / Stark.
Oh, I am still waiting for my flying car or cost-effective jetpack.
It's very easy to compare Elon Musk to Tony Stark but I have yet to see a flying suit that can take a hit from the Hulk much less fly at Mach speed. Yes, Elon Musk has got his Engineers to build the Tesla electric car which is not that cheap although I will admit it does have an EPA-rated range of 335 miles (540 km) on a full charge compared to other electric cars which have half that range but at a third of the price.
Yes, rockets are great but they are expensive and not that reliable (about 92%) however I notice that Elon Musk's rockets have yet to be manned. I am discounting Space X since that did not achieve orbital velocity.
Therein lies the problem when confronted by hype if you are a sub-professional, professional or a scientist you should always choose not to believe until you can see the evidence. In fact the more hype (especially on media) the more skeptical you should be. There is a saying "If something sounds too good to be true it most likely is". Taking all into account I chose not to overestimate Elon Musk.
C'mon, the "landing fuel" is miniscule since the great mass of the rocket at launch is the "lift fuel" which is gone after the rocket does its primary function. The thing that lands is a hollow, comparatively lightweight tube requiring a slight amount of fuel to accomplish the landing.
Really. Have you done the calculations?
Here is a fairly simple calculation to reach the international space station which is 408 km above the earth. Plugin the number 408 into the Orbit of a satellite Calculator and you will get an Orbital radius of 6,786.14 km, a Flight velocity of 7.66 km/s and an Orbital period 01:32 (Yes I have rounded the numbers).
Now consider you have to get your rocket from an orbital velocity of approximately 7.66 km/s through the Earth's atmosphere which will heat any exposed surface to incandescence and at the same time hoping you have enough fuel to slow the rocket down to a point where it can land tail first. This is not to say it can't be done since it can but the chance of failure is significantly higher than if it landed as the space shuttle did or by parachute.
Yes, I am aware of Elon Musk's proposal for a rocket flight from the US to other countries. It does sound great if you don't think it though hence hype but that type of hype is going to cost ridiculous amounts of money and somehow I think a 10 to 15 hours comfortable flight in a reliable aircraft is not a bad price to pay.
Also while we are considering rocket space flight how about a simple calculation of the "g-forces" on the human body since the so-called rocket plane will have to achieve near orbital velocity while at the same time being careful of fuel consumption. For acceptable human comfort, you would have to allow for 3g (Space shuttle) or less although you could go higher I very much doubt that you would get the average passenger to accept that.
Yes, it does get more complicated but when human lives are at stake I do have a tendency to err on the side of caution and until we develop anti-gravity where a Nobel prize, fame and money is waiting for the first person to develop this, although "cold-fusion" proponents need not apply.
Do you have any Engineering proof that Elon Musk's proposed Hyperloop is feasible? There seems to be a lot of hype and little real Science and Engineering. You know the disciplines that get things done in reality.
I have not looked at the proposed solar battery installation in South Australia but since I am well aware of power systems design and of Elon Musk's hype I think it will most likely be a lemon although I am open to changing my mind. Basically, the SA Government screwed up big time and I am thankful I don't live in that state. When designing an electronic grid everything is up for grabs in the feasibility stage but you also have to be practical and look at the economics as well. Just going solar using photovoltaic cells is plain stupid since you then will have to consider how the store the energy when the sun goes down and batteries just can't cut it at least not economically. Although if you can show an Engineering proof I am amenable to a change of mind.
Landing a rocket tail first? You do know that any rocket can be designed to land tail first it is just not economically viable to do that especially when you consider that the chances of a failure are so much higher than if you came to land like an aircraft or use a parachute. Like it or not rocket flight is expensive and the chance of getting into orbit is reasonably high at 92% but landing is a totally different matter. I will let you research that since us dinosaurs are incapable of using a four-function calculator much less run a Google search.
Personally, I don't mind admitting I am wrong and taking it on board if you can show I am wrong but calling someone a dinosaur and name calling when you don't even know them that is the sort of thing an SJW would say and for your sake I would refrain from saying things like that in the boardroom where us raptors reside.
I still fail to see how this can Hyper-stuff can make a profit. ok, you can move up to 16 people between points at a very fast speed, yet the cars would need to be spaced far enough apart from each other to provide a save emergency stop if something went wrong with car up front.
If the tube was not evacuated then the cars in the tube could be stopped safely which is not that much different to underground trains that many major cities use. The problem you have is the Hyperlink tube is basically a vacuum tube which if ruptured (and it does not take much to do that) will send out a shock wave which would effectively pulverize pretty much all cars in the tube.
Rather than me waffle on try a simple Google search using "hyperloop flaws" and then decide for yourself. Don't believe the hype.
Making a huge rupture in a 1" thick steel tube will require a large quantity of explosives. Such a quantity of explosives won't harm a bus full of passengers unless they're right next to it, in which case everyone could be killed. We don't take that as an argument for eliminating buses.
What makes you think it will be a 2.54cm (1") thick steel pipe. Have you any idea the tech and subsequent cost that would go into making that type of pipe? Not only that but you have to join the pipes with "O" rings (it is a vacuum tube after all) and you also have to take into account the thermal expansion coefficient of steel.
Remember that what has been proposed is a very long vacuum tube so there would be normal air pressure outside so even with a slight deformation you are going to have a rupture which would send out a shockwave traveling at the speed of sound and anything in the tube would be pulverized.
Rather than me waffle on here is a Hyperloop debunked video. There are others on the Hyperloop as well as other popular but impractical pseudo science Snake Oil.
The tech isn't practical, nor will it be preferred to air travel if similarly delayed by security. However the "abandoned tunnels" will become brand new state of the art bunkers for the military.
How can Musk get so much government subsidies? This is how.
But the tech is practical if you have the mind of a troglodyte. What are they teaching people in the schools nowadays can't people detect the Snake Oil?
Wow so much hype with this project.
Okay, I am an Electrical Engineer with well over 35 years experience so what would I know when there is so much pseudo-science associated with the Hyperloop project. No country and I repeat no country has ever built a vacuum tube that even comes close to the length and diameter that is proposed for the Hyperloop when all you need is one rupture in the tube and you have human jelly jam. Snake Oil sale at it's best especially when you consider that the "laughable" Hyperloop test winner was a 200 mph (320kph) electric car that could not carry any passenger since it was too small and did not depend on the vacuum.
Rather than me go into details why the project is stupid please view (there are others) the following YouTube Hyperloop debunk. In case you think the guy is a crackpot he does have a Ph.D. in science but then again human gullibility knows no bounds especially when something sounds attractive (ie. Solar Freaking Roadways) but can be proven by Science and Engineering that they are impractical.
What next for Elon Musk? A proposal for "Tourist trips to mars using cold-fusion powered flying saucers?"
KDE works just fine if you have enough RAM... typically 32G or more
I call BS on that, have you ever run a Linux distribution with KDE?
I run a Linux desktop (Fedora 26 - KDE Spin) which has 16GB of DDR4 RAM and I am not overclocking. I have never once seen memory usage approach 8GB (the average is under 3GB) much less 16GB and I do run many different types of applications over multiple desktops.
In fact, most applications open in less than one second although there are some that do take five seconds (ie. The Gimp), SSD's are great. My system is coming up for its second year and I have the latest Fedora distribution with KDE and I have never had a performance issue.
In addition, I also have a ten-year-old HP Celeron laptop that I use for testing purposes. It has 4GB of memory and it also runs Fedora 26 - KDE spin. I have not noticed any performance issues with regard to KDE but have found that playback of H265 files (H264 is fine) is problematic but that has nothing to do with KDE.
BTW. I prefer KDE's graphical interface to Windows 10's graphical interface.
Logging does not equal security. Logging enables forensic analysis after the fact.
Cameras don't prevent the bank robbery, but they may help you find the robber.
Well said.
The main problem with logs is how long do you keep them. Normally this is set by company policy but as per usual Governments (usually ill-informed or draconian) seem to want companies to keep logs forever which is stupid since logs do take up storage space.
A very import part of company policy with respect to logs is a statement of who has the right to view them and the reasons for this. Obviously, you cannot stop a System Administrator so there has to be some trust but you can dictate that any external access can only be allowed when the appropriate legal documents are produced.
Marketing is a sleazy business.
Well said.
I have noticed many of my friends have laptops that they spent ridiculous amounts of money on and all they do is surf the web. Some have even justified their purchase saying that they need it for work which IMHO is a really stupid reason unless their work subsidises them. Even purchasing Office applications for basic home use is a waste unless you are running a business and even then LibreOffice is usually fine.
I find that a good desktop and a cheap but functional laptop is the best mix of computing hardware but obviously this depends on what you want your computers for and like you have said too many people want to justify their purchase even though they may not be satisfied.
Not sure how true that is - my linux laptop is having all sorts of issues with skylake especially in the power department
My Intel Core i7 Skylake Desktop has never had a problem with Fedora and I built it in December 2015. Now running Fedora 26 KDE spin without any problems and the machine is up 24/7 except when I get a new kernel then a reboot takes about a minute (SSD's are great).
It is important selecting "Other OS" in the BIOS and Fedora works perfectly with UEFI although you can turn it off if your OS does not support it.
BTW. I have a base Skylake Core i7 6700 since I didn't want the "k" (overclock) version and at idle my machine runs at 40W and if I do video translation (ie. Handbrake) it can draw about 80W with my core temperatures getting as high as 70 degrees C although most of the time my core temperatures (there are four cores) range between room temperature and 30 degrees C depending on what I am doing.
2 words. Star Wars. A large chunk of us don't like going to theaters anymore and would stream it if possible. / me? Wait till it comes out on DVD // get it from the library /// get a week to watch it.
I think you find that new releases on DVD/Bluray/UHDBluray are going to cost more than a months subscription to Netflix.
You must have a really interesting Library that allows you to borrow (for free) movies.
Well, you do need an hour or two to watch most movies.
A cheaper solution would be to organise with your friends a purchasing and sharing plan which is surprisingly legal until the content providers try to restrict their movies to a registered device. If that becomes the case well all I have to do is feed my green parrot whilst taking the odd swig of rum and singing "Yo Ho Ho".
Of course, if the movie companies take draconian measures to restrict their content then it is perfectly legal for me not to watch their content. Somehow I don't think I am going to miss most of the "rinse repeat" movies that are vomited out every year.
I can't wait to see the Slashdot users to line up to defend this criminal.
I am one person who hopes this guy get the full weight of the law thrown at him since I was one of the people affected by the DDoS attack but in my case, I could see what this scumbag was doing but could not legally do anything.
The actual DDoS attack did not affect my machine although it made any outside communication pretty slow to the point where it was just pointless surfing the WEB. I am not just blaming the idiot (why waste grey matter on remembering his name) but the people who let their PC's be taken over to be used in a botnet and it is not that difficult tracing those infected PC's back to their respective ISP's although it would be difficult do anything about them since some were in different countries including Russa, Germany, Thailand ... etc just to name a few.
However, I would never put a Linux in the hands of my mom.
My wife uses Fedora 26 (ie. latest release - took about an hour to install from 25) and she does not have any problems with it.
Yes, I do know that there are people that you should not let within two meters of any electronic device but most people are very capable of running most applications under a Linux distribution although to be proficient in any application you still have to learn it and even if you use Microsoft Windows you still have to learn a particular application either by teaching yourself or getting someone to train you.
The main reason why people use Microsoft Windows is the fact that most PC's (laptops and desktops) are shipped with it (ie. The Microsoft Tax) and most people don't know or care that there are alternatives since it usually is either too hard to grasp or they have locked themselves into a Microsoft ecosystem.
Troll troll troll your boat....
Maybe he is trolling, but he's got a point. In a number of ways, Linux is slowly converging toward Windows, while leaving behind the original Unix philosophy. For ordinary users, Linux in the desktop is making less and less sense, when compared to Windows or Mac.
Do you even know what Unix philosophy is?
Take a look at Free/OpenBSD, HP-UX, Solaris and AIX they are all Unix and they all do things differently. Things change over time get used to it.
As for Linux converging towards Microsoft Windows, I think it is the other way around since what I was doing in the early 1980's is not much different from what I do today when using Linux and I was using Windows on Unix (all types) before Microsoft thought it was a good idea. Also having tested Microsoft Windows 10 in a virtual machine I doubt I would trust it with my personal data.
