Is there an equivalent of this with an http front end, so the client doesn't need to install anything?

I have used such apps before, but it seems they have gone unmaintained and don't work anymore.

> something many of us do not live in today.

As a good portion of the US population is self-sorting into two warring tribes, both bent on screwing each other over by passing laws whose sole purpose is to harass the other tribe and obstruct their ability to live the life they choose. Not to mention folks in other countries caught in wars they didn't ask to be a part of.

There's plenty of "cruel and domineering" to go around these days, and plenty of people who probably feel they have little to no ability to stop someone else from forcing their preferences on them.

both tribes are doing this? What laws are the Democrats passing that are specifically targeted at the Republican demographic? especially with the goal of harassing them?

Although his style would seem off putting, I would not discount him so readily. He is an economist with many published papers under his belt and has worked for the WEF. Whatever happens, hope the outcome is positive for Argentinians.

Edit: bio from WEF website

Licentiate in Economics, Universidad de Belgrano, Argentina; two Master's in Economics, Universidad Torcuato Di Tella and CEDES/IDES. Former: Head Economist, Estudio Broda and Máxima AFJP; Senior Economist, HSBC, Argentina; Adviser of the Argentine Government, ICSID. Currently, Head Economist, Corporación América. B-20/G-20 Adviser and Member, Group of Economic Policy, ICC/G-20. Since 2012, leads the division of Economic Studies, Fundación Acordar, a think tank of national scope. For more than 20 years, University Professor of Macroeconomics, Economics of Growth, Microeconomics and Mathematics for Economists. Has written over 50 academic papers.

This is a video that does a deep dive on some of his writings: https://www.youtube.com/watch?v=MgBKSjtmahs

If anyone is interested on knowing more about his views as an economist.

One thing I didn’t find adequately reflected in this article is how expensive it is being poor. If you can’t afford the more expensive, but more durable version of X, where X is something you really need, means that over time you will spend much more on this than you would have if you could have afforded the more durable option.

At one part of my life I could only afford the cheapest pair of shoes for 10€, and since it was the only pair I owned I needed to buy a new pair every few months. Of course, I quickly paid more on shoes than I would have if I’d been able to afford one good pair of shoes.

> File systems dedupe now

Huh? is there a citation to that assertion perhaps for a particular instance?

pvik · 4 years ago

as far as I know zfs[1] and btrfs[2] support dedupe.

With your setup, is there a convenient way to flip back and forth between which GPU is used by the Linux host vs. which GPU is used by the Win10 guest?

I'd still like to use Windows 10 only for those games that I can't make work on Linux.

pvik · 5 years ago

I use a separate GPU for my linux host and the windows VM.

I am 99.9% sure you can not passthru a GPU to a VM that is being used by the host.

edit: I think I misunderstood your question. The GPU that gets passed thru to the VM, never gets initialized by the host system during boot. So, if you want to change which GPU you want to passthru to the VM, you will have to reboot to allow your host to use the other GPU (and not init the on you want passed thru to the VM).

I would suggest you look at a youtube video where they run thru setting this up, so you get a better idea of what this entails!

DoofusOfDeath · 5 years ago

So IIUC your approach, you're exposing the actual GPU to the guest OS via PCI-passthrough. And in practice that means you'll want two GPUs: one for the host and one for the guest.

But looking at the online docs for VMWare Workstation, it sounds like they take a different approach: the guest VM has a virtual device driver that lets both host and guest OSs use the same GPU at the same time.

I would think the VMWare Workstation-like approach is preferred, because it avoids the hassle of using two graphics cards. I know that Workstation is expensive ($250) and not OSS. Besides those two reasons, are there still reasons to prefer the PCI-passthrough approach?

pvik · 5 years ago

I did not try VMWare Workstation, but I did try VMWare Player and VirtualBox to see if I can get away with running Fusion 360 on a plain VM, and both had extremely horrible performance.

I remember even SketchUp wouldn't start in VirtualBox. I was able to get SketchUp running in VMWare Player, but the performance was very bad.

edit: this was also about 1.5 years ago, not sure how much improvements VMWare and VirtualBox have made in that time in terms of virtualizing GPU calls.

That is why I decided to end up setting up a VM with GPU passthru. It works extremely well for my usecase. I was able to score a cheap GPU for my Linux host (since I do not do anything graphically intensive on Linux, just need to drive 3 monitors), and was able to passthru my more expensive GPU over to the Windows VM. I would assume if you have integrated graphics on your CPU, you could use that for your host OS and get away with having only a single GPU.

Slightly off-topic:

I'm getting ready to build a new Linux gaming PC. I'm considering installing Windows 10 in a guest VM so I can run a few modern games that do poorly under Steam / Proton.

Anyone suggestions for good sources of info regarding which software stacks (e.g., Ubuntu 19.10 + VMWare) are likely to provide a good experience? Graphics performance matters.

I'm unwilling to run Windows 10 as the host OS because of personal feelings about telemetry.

pvik · 5 years ago

My main desktop runs Linux, I do have a Windows VM (on qemu/libvirt) that I use primarily for Fusion360 and some gaming.

I had to setup GPU passthrough with a second GPU for this.

It is not that hard, you will however need to make sure your motherboard supports proper IOMMU grouping. This however, is the tricky part since most motherboard manufacturers do not really provide this information.

platz · 5 years ago

I use emacs for two primary use cases:

- Niche programming languages tend to have invested resources into building an emacs mode for their language. Importantly, these emacs modes tend to be maintained by core language contributors. In contrast, VSCode or other editors tend to be community contributions which are discarded over a period of months/years.

- markdown editing

- that's it (I've tried magit (too clunky/sensitive), org-mode (too much lock-in), etc

On windows i find Emacs horribly slow to render text/buffer updates.

On linux it is blazing fast.

pvik · 5 years ago

I find it weird that your point against org-mode is "too much lock-in".

It is a plain text format, which looks good even wherever it is viewed.

Pandoc even supports org-mode[1], which should let you convert an org-file to say markdown if you want.

You could also try Firefox Color which provides customizable theming for Firefox, I've had good results with it https://color.firefox.com

Firefox Color is great!! It lets me seamless blend firefox with my doom-themed i3wm and emacs.
