The result was I paid $200 for an FX-8350, which probably wasn't AMD's fastest chip at the time

Maybe not, but close - the FX-8370 is just a slightly better binning of the same part.

I remember all of the benchmarks compared it to the i7, which of course trounced it.

Funny thing about that - there were some pretty major discrepancies at the time between benchmarks done using Intel's compiler and those done using GCC. When using GCC, the FX smoked the i7 - it wasn't until the next generation (or possibly the one after that) that the FX started to lag behind. Even today it's reasonably competitive (if not faster than) against Haswell i5s.

The FX-9590 doesnt seem to be a significant step up in performance from the 8350.

The FX-9590 isn't even a step-up - it's the exact same part, overclocked ridiculously (hence the 220W TDP). It's a stop-gap measure by AMD to try and disguise the fact that the FX line-up hasn't been updated in years.

I'm planning an upgrade myself atm, and as much as I prefer AMD, they're literally a non-option to me (even with the sticker shock from i7 prices). I hope Zen goes well for them, because otherwise Intel has a monopoly on high-end CPUs...

You don't need pressure to write with a fountain pen -- at all. (The modern competitor is a rollerball, not a ballpoint; rollerballs don't give you amount of flexibility on nib grind or opportunities for flex and shading effects that you get with a fountain, but at least you're not forced to use tons of pressure). Allows different, more comfortable grips.

I'll second this - using a fountain pen is worth it just for the ergonomics alone. Before I used (not inexpensive) rollerballs, and even then my hand would be hurting after a test or exam, but with a fountain pen I could easily write for more than double the time. It also worked out cheaper too - a $10 bottle of ink with a $20 pen lasted me the duration of my 6 year course, and the bottle is only half-empty.

Comment: Re:App Permissions ring hollow (Score 1) 83

The App Permissions seem to be missing the crucial ability to deny internet access to an app. There are apps where network data connectivity is the problem. Similarly, I wonder if Google will have this permission setting capability on its internal applications. I know that I have a rather tightly worn tin foil hat when it comes to Google and the information they get, but the Xprivacy 'deny' list on my phone is a mile long, and that's with most of their apps frozen or forcibly pulled out, I find that Google's data access on the platform demands a tight leash, leading the 'privacy' and 'permissions' charge to ring of hypocrisy - "we'll make sure that only we have your location" doesn't mean much to me :/

The ability to block internet access would effectively block ads. On the plus side, there are plenty of firewall apps in the Play store (though they do require you to have a rooted device).

If they actually overloaded the Knowledge Graph it would appear in a special box at the top of the results. In this instance it's still just a link.

I just googled it, and it absolutely does appear in that special box. (Interestingly, this is despite it being the #2 result, with #1 being the PBS website.)

Comment: Re:C++ Template Syntax (Score 1) 414

by rdnetto (#49788063) Attached to: The Reason For Java's Staying Power: It's Easy To Read

The syntax isn't what makes C++ templates hard. They're hard because they're templates.

However, they're powerful because of it. There's no "generics meta programming" because generics don't offer any sort of comparable power. That said, the reason template meta programming is so useful is because C++ lacks reflection.

I disagree. Take a look at D templates (and compile-time function evaluation) - that syntax will be easily readable to anyone familiar with a C family language, because it's the same syntax (just with 'static' or 'pure' peppered everywhere).

C++ template meta-programming is hard for two reasons. The first is that templates use a syntax of their own, which is one more thing to learn. The second is that the template language is functional, which is quite alien to most C++ programmers. D uses native D syntax to do the same thing (with the requirement that functions be pure), and that's much easier to read.

by rdnetto (#49766405) Attached to: Choosing the Right IDE

Seriously IDEs are great! I don't understand people on Slashdot who think if its not hard, its not worthy!

That's a bit of a strawman. IMO, the real issue is that people see it as a false dichotomy between a good text editor (Vim, Emacs, etc.) and a kitchen sink of tools attached to something little better than Notepad with syntax highlighting + autocompletion (e.g. Visual Studio). In that comparison, the text editors win because the vast majority of programming comes down to text editing (and possibly thinking, but you don't need a computer for that), and typical IDEs are pretty mediocre at that.

Note that it's a false dichotomy - you can get the benefits of both, either by integrating a proper text editor into your IDE (e.g. Eclim adds Vim to Eclipse) or by adding many plugins to your text editor - I use Vim with 53 plugins, and I have every feature on your list (although hovering over a variable is replaced with typing a shortcut while the cursor is over it). You only need about 10 to get most of the benefits though, especially if you only work with one or two languages.

Comment: Re:Let's hope that Plasma 4 is kept as an alternat (Score 1) 60

by rdnetto (#49761993) Attached to: KDE Plasma 5 Becomes the Default Desktop of OpenSUSE Tumbleweed

- Plasma 4 had the best systray in all the linux ecosystem, allowing KDE native, "new" Unity-style indicators, and old tray icons. Now neither of those work in Plasma 5, leaving empty space or not showing at all. Even Unity has ways to show old tray icons such as Pidgin. When asking about it, was instructed to install stuff like stalonetray...are we in FVWM now?

I've got a pretty good idea why this is happening. The old API for tray icons didn't handle the case where you had multiple systrays correctly (e.g. dual monitors) - the icon would only appear on one of them. The new API fixes this, but as you have noticed not everything supports it. The best solution is probably for someone to go around submitting patches to all the projects using the old API, but that's obviously going to take some time...

Comment: Re: SystemD added? (Score 1) 494

by rdnetto (#49588047) Attached to: Ubuntu 15.04 Released, First Version To Feature systemd

The overarching problem is that systemd can decide to rearrange the boot sequence at any moment.

If a admin has set a sequence to be XYZ they have a very good reason for doing so. So why should the init suddenly decide that YZX is the way to go?

Because parallelism is good for performance, or so the argument goes.

The real issue is that there's no way to reproduce that partial-ordering. IMO, there should be some kind of debug facility to restrict it to sequential startup, then try all possible orders. (Yes, factorial complexity is never fun, but at least it would provide a means to debug this kind of problem. Making open source software easy to debug (or at least capture logs for) is hugely important, because that's where most of your drive-by patches come from.)

Time to start masculanism movement, because anti-male gender discrimination hit mainstream.

It exists, but isn't particularly well known.

IMO, feminism and masculinism are both inherently flawed, in that they only focus on one set of symptoms and don't try to fix the underlying issues. Both genders have issues, but the moment you try to draw attention to this people tend to take it as a competition / zero sum game. The real solution is something like egalitarianism, where the focus is on not discriminating against people regardless of their gender, etc.

KDE 4 broke a lot of the functions I used on 3 (like, for instance, email. KMail was great, now I'm stuck with the inferior but functional Thunderbird). And they never did fix them. Still broken and worse with every revision.

So I'm dreading the day when the only supported KDE will be the still-not-fully-functional version 5. What have they broken now, never to fix?

Speaking as someone who only started using KDE after 4 had stabilized, what did they break in Kmail?

The reasons are clearly described here

I read through that and didn't see anything about "We're all idiots".

Their reasons involve context switching and interprocess communications. Context switching has got to happen (unless they run IE in kernel space) so just get it over with. Interproces communication has always been a weakness in Microsoft systems. Since day one. Multitasking OSs are here, folks. Get over DOS.

If your context switches are too slow, the correct solution is to fix the kernel or add syscalls to reduce the overhead (see sibling post). Moving parts of your application into kernel-space is bad design no matter how you look at it. (Besides, wasn't it only a few years ago they had a vulnerability in their kernel-mode font driver?)

Comment: Re:Never consumer ready (Score 1) 229

by rdnetto (#49483453) Attached to: 220TB Tapes Show Tape Storage Still Has a Long Future

It's usually cheaper to use consumer drives and some better software to manage the inevitable failure than to use enterprise drives.

There is NO difference in reliability between "consumer" and "enterprise" drives. The only reason to buy enterprise drives is because you have excess money that you are too stupid to keep. All the big storage companies use consumer grade drives, and several of them, including Google and Backblaze, have published data that clearly show there is no reliability or performance reason to buy "enterprise" drives. They are a scam.

IIRC, there is one difference: how they respond to read errors. Consumer drives will keep trying to maximise the likelihood of a successful read, while the enterprise ones will just fail immediately since they're expected to be RAID, so there's another copy of the data and taking longer to reply just kills the throughput.

Serious question: how does one meaningfully distinguish between hardware and software patents? As I understand it, software is supposed to be unpatentable because it is just math, but the same could also be said of Widlar's negative feedback amplifier, since the mathemathical models by which transistors function were well established at that point.

The best argument I've heard against software patents is that they inhibit interoperability (e.g. the MPEG patents), but that's not specific to software - the same is true of Apple's magsafe connector.

OK, so let's see. Other than the network card, mouse, 2D graphics, sound, CPU, 3D graphics, battery and the fact that normal usage melted it, it works awesome. I think I'll stick with Windows 10 TP on my laptop, where I've only had minor network issues requiring a reboot to get it back sometimes.

To be fair, Arch is a distro for people who are fine with things breaking all the time, which is what you'd expect of a bleeding edge rolling release distro. A review of someone who spent a year running Ubuntu on their laptop would be far more realistic in terms of what a casual user would experience.
