@Kazander said in Scientists ‘reverse time’ with quantum computer:
Hmmm. I think popular media has over-hyped things again.
They reversed a time-reversible process...this isn't the same thing as actually reversing time.
This I thought at first also, but reading the essay in the PDF I have seen that the flow of time has actually been reversed at the quantum level, although I think it is a phenomenon not transferable to this, given the strange behavior of the physical laws at this level.
But if it can mean an important advance in the terrain not only of the computer science, but also in the communications, as I mentioned in the previous message.
Some time ago I thought, reading about another experiment about the speed of light, which in some way is related to the flow of time, the objective relativity that it really has, when they seized to stop the speed to zero.
Let's write it down clearly: SMS and call log permissions can only be accessed by apps that have been chosen as default apps for calls or messages. If an app hasn't been selected as default, it loses these permissions. Apps that don't ask to be default handler cannot have these permissions. This is more babysitting from google, to protect the stupid average user from themselves. Nothing more, nothing less. They do the same thing on Chrome. It's old news. Personally I really don't care, I don't want any app to read my messages or phone logs, if I don't make phone calls or message with it – I welcome the change. Now, some people might rely on an app that needs these permissions without being the default app – for those that sucks. We will see how this plays out.
I have in my PC enough software which is considered essential, such as free Office, Gimp and others.
But I have an old PC and not very powerful and they are quite slow and heavy and therefore I use less and less these applications, using excellent applications online, much more simple to use, quick and covering almost 99% of what I need,
I think that there are many users who do not need much of the functions that incorporate modern applications and makes them unnecessarily heavy and slow, without offering significant advantages for it...
I don`t need 5000 functions and formats to write a letter and not 8000 templates, filters and brushes, if I am not a professional designer.
I mentioned before the MS Works, version Light of the MS Office, Windows included free to XP and that was a real delight, offered the same applications of MS Office (wordprocessor, spreadsheet, database, etc) with fewer features but sufficient for the vast majority of user. It was quick and very light, but died hidden within the system, while many users were aware of its existence, MS promoted its MS Office in first line and not mentioned this small and free beauty.
@duarte.framos If that's got you convinced to switch to Linux, this should have you sold:
and lastly, www.kmfms.com/alternatives.html
On the last site, it does look a little old, but it's still pretty relevant. Bttom line, I just think that Microsoft makes products that are really not great at all, and they've taken up a pretty big monopoly of the industry and held it back. I think the Surface Studio looks decent, so I'm surprised they actually made a decent-looking rounded piece of hardware, which contrasts their squared off UX design, but it looks nice and I hear it works well. Other than that, I find MS software to be a lot worse than the competition. It just doesn't work, it's buggy, unstable, and resource-heavy. As an OS, I find Linux far superior, which I use more and more lately.
As for the other alternatives, like email, I've used Outlook and it's a nightmare, so I switched. I still use Gmail, which I don't love, and I want to use Protonmail, but at least both are better than Outlook by far.
For office suites, I haven't used MS Office in years, and I'm sure it's alright, but other than compatibility, it doesn't sound like it has things I absolutely need. LibreOffice has everything I need, it's very compatible with MS Office, and it just works. I don't feel the need for anything else.
I never used IE, and I don't use the new Edge, but there's not much that is really different from Chrome and Firefox.
As for gaming consoles, I never had an Xbox, and besides Halo and maybe some other exclusives, I just find Sony and Nintendo more appealing and unique.
As for PC gaming, that's the only thing Windows seems to be better at than the other OSs. Steam still needs to catch up on Mac and Linux, and until then, it's best to play Steam on Windows. Though there are still some popular games on Steam for Linux, so you might not be exclusively playing on Windows. And you might want to use W10 instead of W7 for that, since W10 has DX12.
These days, it just looks like the only thing that Windows has over the competition is gaming, and in other areas it doesn't outshine Mac and Linux in. I just find that MS makes really mediocre products, and have always done so. That's my 2 cents on the matter.
The only OS for desktops work that comes close to Windows is Linux and FreeBSD but you can always look at alternatives like AmigaOS, MorphOS, SailOS and hopefully others. We all need to get away from Windows and fast.
So, do you have "optimal parameters" for video, audio or anything compression ?
If your problem is the space occupied on the data HDD or partition you should look at the deduplication, not compression.
You can enable it on win8/win8.1/win10 and is pretty effective.
I have freed over 600GB of spaceover 3.6GB of data (1/3 videos, 1/3 Iso, 1/3 generic documents)
Does the keyboard have to be removable? I've seen a few laptops with either a 360 degree hinge so the keyboard folds under, or with a pivot so the keyboard twists around behind the screen. Obviously such a thing would weigh more, but you can't forget or lose the keyboard that way.
Searching on Walmart.com comes up with 24 "2 in 1 laptops", including some by Lenovo and HP. Conversely, Logitech does make a nice Bluetooth keyboard you could use with any Bluetooth-enabled tablet - be it Android, Windows 8.1, or even iOS. (I have one and use it with my Nexus 7.)
