XMPP Operators Begin Requiring Encryption, Google Still Not Allowing TLS

DdJ Re:Google is dropping XMPP and Talk/Chat anyway (121 comments)

Or can you give me one good, solid reason why an ordinary person would want to use a non-Google XMPP server?

Some employers provide on-site supported XMPP servers. Until recently, I've been able to use ours to collaborate with external partners on GTalk, using federation.

Some vendors provide built-in XMPP servers as part of other products. I'm aware of one telephony platform that does so and one IT helpdesk service that does so. Using their servers enables certain useful features, like "they look like text messages to phone users" and "customers can open issues with the help desk by sending them IMs". Those are more useful when federation works.

Some web service providers have XMPP support in their service platforms. I used to be able to have IFTTT send messages to me, due to federation. Google's announcement about turning off the service has caused them to remove the channel from their service entirely. Now I can't use it anymore.

(Those are just the ones that have been impacting me personally as of late. I'm sure others could think of more. No, they're not mainstream. Yes, they're real.)

Ask Slashdot: Minimum Programming Competence In Order To Get a Job?

DdJ Re:As a Sr. Analytics Manager... (466 comments)

As an analytics manager you want to see Excel? Why? If someone on your team can do everything else that you list, plus maybe Python, Octave or MATLAB then why would you want to dirty yourself with Excel?

At a guess; because a ton of the data you receive will come by default in Excel format, and because a ton of the recipients your'e going to be asked to deliver data to will want it in Excel format.

I've begun doing some analytics in my current job (which is pretty much all Unix, all server-side), and I'm finding this to be the case surprisingly often.

Ask Slashdot: Minimum Programming Competence In Order To Get a Job?

DdJ Nope. (466 comments)

And perhaps we can agree that a level 2/10 would not likely get hired anywhere.

I'm not prepared to concede that. I'm also not prepared to concede that it should be the case.

If there are a large number of 2/10 programmers out there not getting hired, then more value can be extracted from the workforce if someone can come up with a sandbox or somesuch in which they can actually be used productively.

Maybe you get four of them and have them keep swapping off in pair-programming pairs. Maybe you only let them write code that goes into a continuous-integration server. Maybe you only let them write social games. (Heck, maybe you use them as living, breathing "fuzzing" tools for toolchain developers to use in debugging.) I don't know.

But the economy is better off if we can figure out how to extract value from them. (They should be paid very poorly compared to better programmers, however.)

Mathematical Model Suggests That Human Consciousness Is Noncomputable

DdJ Re:Memories do decay (426 comments)

it's not the act of recollection that causes the memory to decay.

What's your basis for saying so?

(I mean, it's trivially true that it's not the only thing that causes memory to decay. I'm not asking about that. Do you have a basis for saying that it's not a thing that causes memory to decay?)

The act of recollection might very well cause the memory to decay. Our brains may "wrap" it in a "macro" that "re-writes" it as we recollect it, so that it does not seem to decay as a side-effect of recollection. I'm not aware of data we have that would let us rule this out.

Based on that, I find the whole article suspect.

Apple, Google, and Amazon's Quest For One Remote Control Is Futile

DdJ Re:Damn you, Amazon and your bluetooth! (130 comments)

So you're uninterested in turning things on and off, and adjusting the volume?

I'm uninterested in "just one remote for everything". (Volume is not a problem.) I have seen that work out so rarely that I prefer to avoid situations where people attempt it.

Apple, Google, and Amazon's Quest For One Remote Control Is Futile

DdJ Re:Damn you, Amazon and your bluetooth! (130 comments)

Archaic. None of the "remotes" that I use in my living room are keyboards.

When I hear "remote," I think "something simple and dedicated that I can hold in one hand to easily control remotely-located things." I don't think "something with at least 60 buttons, some of which are actually useful, that takes up too much room on the coffee table, and functions only as a basic input for a single device."

Huh? I'm not talking about the remote being a keyboard, I'm talking about the remote identifying itself as a keyboard. It's the equivalent of bar-code scanners that you plug into a keyboard port and that "type" whatever you scan with them.

Keyboards have some buttons that are very good for remote control functions, like "up" and "down" and "left" and "right" and "enter" and "escape" and "pause/play" and "fast forward". Make a handheld stick with just those buttons, and have it pair over bluetooth as a keyboard, and that remote would then work with an Apple TV, an Ouya, a Fire TV, a Linux box running MythTV, a Windows box running Steam in big picture mode, et cetera, et cetera. That's what I'm talking about.

Neat. Now how easily does it switch between presentations, AppleTV and Ouya? Does it change inputs on the TV and/or AVR? Turn things on and back off again? Turn the volume up and down?

No? Oh. I'd consider that a lousy remote, then.

I see. There are features in a remote that I'm so uninterested in that I don't even think of them, that you consider absolutely essential. (Though a subset of those are easy. They could all be easy given specific device choices which I'm not going to assume.)

You and I will not like the same remotes.

Apple, Google, and Amazon's Quest For One Remote Control Is Futile

DdJ Re:Damn you, Amazon and your bluetooth! (130 comments)

Is there any such thing as a "standard" Bluetooth remote?

Well, the device presents itself as bluetooth using the HID profile. That's a start.

Given that, I'd consider any remote that presents itself as a keyboard with well-defined keys to be extremely standard. (Remember, media control keys like "play/pause" and "fast forward" are well-defined and widely supported on keyboards already.)

Further, I'd consider any remote that presents itself as a gamepad with well-defined buttons to be extremely standard.

A remote that presented itself as a trackpad with standard buttons wouldn't be too bad either.

(I in fact often carry a bluetooth device that's remote-sized and is a full keyboard with integrated two-button trackpad and built-in laser pointer. It's hard to beat for presentations, and also controls my AppleTV and my Ouya very nicely.)

That said...if you want custom integration, Bluetooth is overkill. These things are implicitly already on the network. Just use IP.

That would currently require a bunch of one-off solutions, as there isn't a "standard wifi HID profile" to use. Myself, I'd rather have an app on my phone that presented itself to the world as a bluetooth keyboard or gamepad that I could then use even with devices that didn't have IP at all.

Apple, Google, and Amazon's Quest For One Remote Control Is Futile

DdJ Re:Damn you, Amazon and your bluetooth! (130 comments)

I know this isn't what you meant by "not wanting to give up our remotes," but am I the only one annoyed by Amazon for going with a bluetooth remote?

I don't know enough to answer that yet.

I would not really prefer IR.

If the bluetooth in use is extremely standard, so that other devices and even software can be used to "emulate" it, then I'm delighted, as I'll (eventually) be able to integrate the box with other stuff.

If it's doing something grossly nonstandard, that just happens to be implemented on top of bluetooth, then I'll be annoyed.

Are DVDs Inconvenient On Purpose?

DdJ They don't. (490 comments)

Specifically: Why do movie studios allow Netflix to send out DVDs to their subscribers by mail, but not to allow the same option in the form of "virtual DVDs" that you could "check out" through their website, and stream them while they're checked out to you?

As far as I know, they don't "allow Netflix to send out DVDs". Content owners have in the past tried to forbid media rentals, but failed. They don't "allow" Netflix to do this -- they simply have no legal standing to prevent it. They likely would if they could.

At least that's my understanding of things.

Linux May Succeed Windows XP As OS of Choice For ATMs

DdJ They using winelib? (367 comments)

If these systems are still using XP today, my bet is that they only rely on a small, stable, well-established subset of what we consider today's Windows API. It really wouldn't surprise me at all if a whole bunch of the software involved built flawlessly with winelib.

Anyone know if that's how they're going about it?

Linux May Succeed Windows XP As OS of Choice For ATMs

DdJ Re:Here's what I don't get (367 comments)

What's a desktop operating system doing on an ATM anyway?

The same thing a desktop CPU is doing in both servers and embedded applications.

Economies of scale and network effects (eg. huge development tool ecosystem) provide some advantages that grow over time, and eventually overcome the advantages of other solutions.

The same thing relates to why an Android phone runs (essentially) the same kernel as an OS Oracle sells to run their database servers on, and why an iPhone runs the same kernel as a Mac Pro.

Time Dilation Drug Could Let Heinous Criminals Serve 1,000 Year Sentences

DdJ The reverse? (914 comments)

What about doing the reverse, for life sentences?

Sometimes someone innocent is given a life sentence, and that fact comes out later. They can be freed, but the amount of damage done to them is still high. Could the reverse of the proposed idea be used to lessen that damage?

(The idea would be to use it on everyone. If they're guilty and never released, so what? But might it be a way to minimize damage when mistakes are made?)

Lies Programmers Tell Themselves

Bitcoin Inventor Satoshi Nakamoto Outed By Newsweek

DdJ Re:Protection from what? (390 comments)

It's like, imagine you're a bank robber and you've got two banks in town. One is an old-school bank that has thwarted dozens of bank robbers in the past and routinely. They hire people specifically to worry about bank robbers. On the other side of town, there's this new hip young bank that's getting money thrown at them like mad. They used to just take all the money home with them at the end of the night, but now they've got this new "cold storage" place to put money they're not using at the moment. They're known to be idiotic fools, everything thinks the whole thing is a fly-by-night operation, and they don't even have a safe.

You intended this to be a metaphor for attacking traditional financial institutions versus attacking Bitcoin exchanges, right?

(It certainly works as a metaphor for that.)

Apple Drops Snow Leopard Security Updates, Doesn't Tell Anyone

DdJ Re:Is anyone actually stuck on Snow Leopard? (241 comments)

I think that you'll find that Windows 8.1 will perform like shit on those machines... Not only because all of the rendering will be software-based.

Huh. Windows 7 certainly runs very well on some of them, with hardware-accelerated rendering and everything. Why would the rendering in Windows 8.1 switch to software-based?

Apple Drops Snow Leopard Security Updates, Doesn't Tell Anyone

DdJ Re:Is anyone actually stuck on Snow Leopard? (241 comments)

If someone is still using Snow Leopard for software purposes, it's probably best done in a VM now. Lots of new features and performance in Lion and later assuming you have at least a 5 year old machine or later.

I agree, but the normal release of Snow Leopard is not licensed for running in a VM. If you run it in a VM, you're violating your license. (This is the reason I own a copy of Snow Leopard Server -- that is licensed for running in a VM.)

Further: not all apps that run under Snow Leopard will run in on a VM -- for one example, some that depend on OpenGL will refuse to run. (Diablo 2 happens to be an example. I tried it out of curiosity, using the latest release of VMWare Fusion.)
