Computers / Re: Reliable free file hosts in 2019?
« Last post by James Daniel Marrs Ritchey on October 13, 2019, 10:18:00 AM »
The best one I know of currently is Mega.nz (https://mega.nz). It started out good, but it has made changes over the years which negatively affect free users. Originally it provided 50GB of free storage. I think they did this to popularize the site, because no one else was offering anywhere near that to free users at the time. Then they changed it to 15GB. Now they've made it so that you start with 15GB, but you can earn up to 50GB, but the additional earnings are only valid for certain time periods (eg: 30 days, 180 days, etc). Also now, they crack down more on deleting "inactive" accounts so they can free up storage. I wouldn't call Mega a good option anymore for free users, as the changes in storage space prove them to be less reliable than I once thought, but they are still a decent option.

One thing to keep in mind with Mega is that the company is based in New Zealand, but not all of their servers are there, and they don't state where their servers are. This is important, because how much legal control over your data you have is dependent on which countries you're storing it in. However everything you upload to Mega is encrypted so that only you (and anyone else with the decryption key) can access it. Mega itself doesn't have access to your files which helps protect your control regardless of where in the world your content is physically hosted.

Computers / Reliable free file hosts in 2019?
« Last post by James Daniel Marrs Ritchey on October 13, 2019, 10:00:53 AM »
Each year there are fewer and fewer file hosts period, let alone free files hosts, let alone free file hosts which don't require registration. Many of the hosts available now in 2019 are small services which disappear after a year or two. The few bigger services still in the game have long since rebranded as cloud backups, but they typically have the ability to create download links for things you wish to share. Basically, it has all been downhill since the Megaupload seizure in 2012.

Enceladus appears it could have the ingredients needed for life to arise, but at this time it isn't known if life has, or if Enceladus has the conditions necessary

Back in 2005 the Saturn probe determined the planet has water which all known forms of life need.

Windows 10 / Re: Windows 10 Is 4 Years Old
« Last post by James Daniel Marrs Ritchey on October 03, 2019, 09:05:15 PM »
It appears Windows 10 doesn't follow the old lifecycle form. Each release has it's own short term support cycle. Keep your system updated, and Windows 10 forever I guess?

Windows 10 / What Is The "lifetime of the device"?
« Last post by James Daniel Marrs Ritchey on October 03, 2019, 09:04:05 PM »
One thing that has been unclear since the beginning of Windows 10 is how long you will receive updates for. Microsoft has always stated you can update for the lifetime of the device, but what is the "lifetime of the device"?. Does Microsoft determine the life of the device, or do the component/computer manufacturers? As far as I can tell it's both, but mostly the manufacturer.

According to the System Requirements page you may not be able to update anymore if there are no drivers compatible with the updated version of Windows. So this would mean if the manufacturer doesn't provide updated drivers, and if there aren't any suitable generic Microsoft drivers, you might not be able to update anymore.

It also states that the system requirements for Windows may change over time. Though it does appear you can install Windows 10 even if you don't meet all the "requirements" I would imagine there are limits to how far you can push this, and it might prevent you from updating.

Space / Is there life on Mars?
« Last post by James Daniel Marrs Ritchey on September 11, 2019, 10:27:07 AM »
Mars's soil is full of Perchlorates. On Earth some microbes eat these, but it is also toxic to many forms of life including humans. They are also explosive when heated (reminds me of that Star Trek episode where Kirk visits a planet with exploding rocks). If there is life on Mars it's probably below the surface, or just microscopic life if it's on the surface.

Space / Why do people want to colonize Mars?
« Last post by James Daniel Marrs Ritchey on September 11, 2019, 10:07:03 AM »
I can understand why people want to examine Mars, even visit it. Who knows what might be found there. But I don't get why anyone would want to live there permenatnly when it's a barren inhospitable wasteland. I suppose the l lack of mosquitoes would be a plus, also no crowds, and you get to wear cool space suits all the time. Never mind, sign me up :P. In all seriousness though, unless there's a secret garden underneath the surface you'd be completely dependent on importing food, medical, and building supplies from Earth much like living in Antarctica, and no-one lives there. It's just researchers visiting for the purpose of doing research.

Space / Are There Any Known Earth-like Habitable Planets?
« Last post by James Daniel Marrs Ritchey on September 11, 2019, 09:54:34 AM »
Back around 2014 there was a lot of talk about Kepler-186f. As far as I know, it's the best candidate to date, but mostly because it's so far away that little can be determined about it aside from it being in the habitable zone of it's star. Just this year the planet GJ 357 d was discovered which might be a better candidate as it's significantly closer to Earth, but not much is known about it yet either. Hopefully the next-generation telescopes Large Synoptic Survey Telescope (LSST) and the Giant Magellan Telescope (GMT) will be able to provide more insight into GJ 357 d?

Computers / Re: Comparing CPUs
« Last post by James Daniel Marrs Ritchey on September 05, 2019, 03:08:23 PM »
From what I can see, it doesn't seem like CPU manufacturers provide the IPC on CPU specification documents. Apparently IPC is also somewhat variable between different instructions (basically some software is easier for the CPU to run than others). It is possible for the end user to calculate IPC, and by doing so with many different instructions derive measurements which are useful in comparing CPUs. To accomplish this you have to divide the number of instructions in the program code by the number of clock cycles it takes to complete them. Not sure how to accomplish that.
