Firefox 33 Integrates Cisco's OpenH264

emblemparade Re:bad for standards (194 comments)

This has nothing to do with the "tag" itself, which does not specify codecs. Yes, this is still a compromise, but many of us have been compromising for years on various aspects of freedom and openness. Choose your battles carefully and you can win the war: Mozilla has already achieved so much for the open web, and I'm confident the upward slope will continue.

MicroxWin Creates Linux Distribution That Runs Debian/Ubuntu & Android Apps

emblemparade Move along (42 comments)

No software downloads, and apparently not open source nor free software. And also their hardware is not yet available.

Who tagged this "Ubuntu"? No relation.

Android Needs a Simulator, Not an Emulator

emblemparade Genymotion (167 comments)

I agree: indeed Genymotion fills in this gap perfectly, and I recommend it strongly for any Android dev. I also found Genymotion devs to be amazingly prompt in responding to bug reports. (I have no connection the company, am just a fan of their work.)

But it's still surprising the that official Google toolkit doesn't have anything like it. Google, get on board! Just buy up Genymotion or license their tech.

By the way, emulation still has its uses in some cases... it's of course best to have both.

Misogyny, Entitlement, and Nerds

emblemparade Re:Stupid Blame Game (1198 comments)

Why not read TFA?

Chu is using the opportunity that mysogyny is in the spotlight to discuss the problem of mysogyny in his own community, through his own personal experience.

He is not saying that Rodger is a nerd.

Seriously, read TFA, it's a thoughftul piece.

Ask Slashdot: Which NoSQL Database For New Project?

emblemparade Re:Short Intro (272 comments)

I agree, entirely. Even more interesting are the recent "noSQL" features added to Postgres. The fervor of the "noSQL" is too often "anti-SQL," in a ridiculously technically uninformed way.

Ask Slashdot: Which NoSQL Database For New Project?

emblemparade Short Intro (272 comments)

It's a mistake to think that "NoSQL" is a silver bullet for scalability. You can scale just fine using MySQL (FlockDB) or Postresgl if you know what you're doing. On the other, if you don't know what you're doing, NoSQL may create problems where you didn't have them.

An important advantage of NoSQL (which has its costs) is that it's schema-free. This can allow for more rapid iteration in your development cycle. It pays off to plan document structures carefully, but if you need to make changes at some point (or just want to experiment), you can handle it at the code level. You can also support older "schemas" if you plan accordingly: for example, adding a version tag or something similar that can tell your code how to handle it. So, even ignoring the dubious potential of better scalability, NoSQL can still be beneficial for your project.

More so than SQL, NoSQL database are designed for different kinds of applications, and have different strengths:

MongoDB is a really good backend engine that gives programmers lot of control over performance and its costs: if you need faster writes, you can allow for eventual integrity, or if you need faster reads, you can allow for data not being the absolute freshest. For many massive multiuser applications, not having immediately up-to-date data is a reasonable compromise. It also offers an excellent set of atomic operations, which from my experience compensate well for the lack of transactions. Furthermore, MongoDB is by far the most feature-rich of these, supporting aggregate queries and map-reduce, which again can make up for the lack of joins. It also offers good sharding tools, so if you do need to scale, you can. Again, I'll emphasize that you need a good understanding of how MongoDB works in order to properly scale. For example, map-reduce locks the database, so you don't want to rely on it too much. The bottom line is that MongoDB can offer similar features to SQL databases (though they work very differently), so it's good for first-timers.

Couchbase is very good at dispersed synchronization. For example, if parts of your database live in your clients (mobile applications come to mind), it does a terrific job at resynching itself and handling divergences. This is also "scalable," but in a quite different meaning of the term than in MongoDB.

I would also take a look at OrientDB: it's not quite as feature rich as MongoDB (and has no atomic operations), but it can work in schema-mode, and generally offers a great set of tools that can make it easy to migrate from SQL. It's query language, for example, looks a lot like SQL.

The above are all "document-oriented" databases, where you data is not opaque: the database actually does understand how your data is structured, and can allow for deep indexing and updating of your documents. Cassandra and REDIS (and Tokyo Cabinet, and BerkeleyDB) are key-value stores: much simpler databases offering fewer querying features: your data is simply a blob as far the engine is concerned. I would be less inclined to recommend them unless your use case is very specific. Where appropriate, of course simpler is better. With these kinds of databases, there are actually very few ways in which you can create an obstacle for scalability: simply because they don't do very much, from a programming perspective.

There are also in-between databases that are sometimes called "column-oriented": Google and Amazon's hosted big data services are both of this type. Your data is structured, but the structure is flat. Generally, I would prefer full-blown "document-oriented" databases, such as MongoDB and OrientDB. However, if you're using a hosted service, you might not have a choice.

It's also entirely possible to mix different kinds of databases. For example, use MongoDB for your complex data and use REDIS for a simple data store. I've even seen sophisticated deployments that very smartly archive data from one DB to another, and migrate it back again when necessary.

Ubuntu 14.04 Brings Back Menus In Application Windows

emblemparade Re:Change for change's sake is annoying (255 comments)

I want to point out that Unity is a very keyboard-friendly UI. The team has gone to extra lengths to make sure keyboard shortcuts exist for just about everything.

And I'm saying this a Xubuntu user! I've decided against using Unity for now (I feel it's still "beta" quality), but I appreciate the efforts of the Unity team. Perhaps one day in the future it will match my needs. Until then, Xfce is a "good enough" daily driver for me.

And Xubuntu = Ubuntu. I'm exceedingly grateful to the Ubuntu community for the extremely high quality repository of software they maintain.

PC Makers Plan Rebellion Against Microsoft At CES

emblemparade You mean, doomed like iPads? And ChromeBooks? (564 comments)

Everytime I see "doomed" in Slashdot these days, I expect a big hit around the corner...

Actually, it seems, many home users don't need full-blown MS Office and Photoshop, and are very happy with modest apps and casual games. If not more happy, because the full-blown desktop OSes give them headaches. An antivirus? System update that takes 45 minutes? My mom doesn't see how that helps her. These people love their iPads and the ChromeBooks are selling like hotcakes.

And MS is scared of ChromeBooks, enough that they've released a series of anti-ChromeBook ads.

Selling a laptop dual-booting Ubuntu is pointless (and I say that as a 100% Ubuntu supporter): but dual-booting Android indeed gives the laptop a different experience, with superfast boot and simple use, that many users will enjoy. If the laptop does touch, too, then you get a nice Android tablet, too, which is far more functional than a Win8 tablet: indeed, PC+.

Also, let me educate you: Android *is* a Linux distro.

PC Makers Plan Rebellion Against Microsoft At CES

emblemparade CrossOver (564 comments)

The MS Office requirement used to be a big deal for me, until I recently gave CrossOver a whirl. It supports "only" Office 2010, not 2013, but I found that it works perfectly well, no bugs yet (and I use it a lot). So, for me, CrossOver solved the last hurdle requiring Windows.

Ask Slashdot: Easy Wi-Fi-Enabled Tablet For My Dad?

emblemparade Re:Get an iPad (370 comments)

I guess YMMV. I suggest the iPad, strongly.

I got my parents each an iPad as a gift, and it was life transforming, especially for my mom. She never got a hang of computers, even though she even tried to take some computer classes. The mouse, the overlapping windowing interface, dialogs that pop up... a constant source of frustration. Desktop OSes require so much knowledge to just do basic things: we who were raised with them take it for granted. But the iPad somehow made sense to her. She never stops thanking me for it! She emails every day, looks up things in Google, and has recently started to use Facebook (although she is very confused by the interface... heck, I'm a programmer and I can barely understand FB's interface...). We also use Skype a lot, and it works great! Though she often forgets that she needs to "see my name in green" to know that I'm actually have Skype open. She thinks of the whole device as "also a telephone" and still doesn't quite understand that an "app" has to be open.

Related: my mom had a Galaxy phone at the time, and of course couldn't make heads or tails of it. But, once she "understood" the iPad, she also understood that the iPhone is just a "small iPad", and got one for herself. I'm so proud of her. :) It's also really interesting for me to see how she is exploring this new world in pretty much the opposite direction of what I expected: tablet first, smartphone later. Also interesting, I thought she might find the iPad Mini better, because she carries her iPad around all the time. But she told me she saw one that a friend of hers had, and thought it was ridiculously small and pointless!

For the record, I'm the ... opposite of an Apple fanboi. I have a Nexus 10 tablet myself, rooted with CynaogenMod. I use Ubuntu exclusively for my desktop and traveling netbook. For my needs, those are definitely the better choices. But for my mom, I must concede that iOS is simply easier to use. Fewer menus, fewer options, and that's all good for someone who is confused by even one option. I've learned that my mom not only has different needs, but also views these technologies from an entirely different, and I would say fresher perspective than mine.

Trust me: get you dad an old iPad, it may change his life. You definitely don't need an iPad 2 in terms of power, although consider the iPad Air. I'm thinking of upgrading my mom to it, I think she might appreciate the lighter weight.

Also: I don't know how old your dad is and how his vision is, but also look into increasing the font sizes, and show him how to use the click-zoom feature. It's built into the iPad, and can definitely help older folks.

The Desktop Is Dead, Long Live the Desktop!

emblemparade Re:Loss of economies of scale (453 comments)

You're right: I think the category of "budget computers" will pretty much disappear. But is it going to be such a loss? Our phones are already more powerful than most budget computers. Once OS convergence happens (Ubuntu Phone, please), for many of us there won't be any reason to carry around a laptop.

The Desktop Is Dead, Long Live the Desktop!

emblemparade Workstations (453 comments)

You're right: desktops will become workstations (if they're not that already). They will continue to be very powerful devices suited for very particular work, that either requries a lot of computational power or is ergonomically sutied for a desk-and-chair.

Until quite recently, desktops were multipurpose devices: they did all that but also browsed the web, did word processing, and other lighter tasks. They'll still be able to do that, for sure, it's just that unless people need the workstation stuff, there are simply better devices than desktops.

The desktop isn't dying, it's just narrowing its mission.

The Burning Bridges of Ubuntu

emblemparade Re:No it is not kvetching. (346 comments)

I agree with your idea, but you got it a bit wrong: Xubuntu it still Ubuntu. I think many people hate Unity (I don't; I just treat it as an "early beta" of an idea that one day might work), but don't realize that things like Xubuntu and Kubuntu are very much still Ubuntu.

The desktop interface is a *very tiny* part of the OS, really. But it's the first thing most users see, and is crucial for PR.

I love Xubuntu. Hence, I also love Ubuntu (if not the Unity package) and the great work done by everyone involved.

Ubuntu should follow the openSUSE way: when you install it, it asks you which desktop you want. There's no realy need for separate distros, IMO.

OpenSUSE 13.1 Released and Reviewed

emblemparade Excellent installer! (113 comments)

openSUSE's brilliance is that it allows to choose the desktop you want during installation. This is vastly preferable to Ubuntu's requirement of downloading different flavors (Kubuntu, Xubuntu, Lubuntu, GNOME Remix). I also imagine that it's easier for devs, because it involves less packaging and distribution work.

I'm sticking with Xubuntu myself, because I much prefer the Debian way of doing things. Still, it's heartwarming to see that some things *can* be done better.

Battlefield Director: Linux Only Needs One 'Killer' Game To Explode

emblemparade They *do* want an open platform (410 comments)

You're plain wrong.

Gabe constantly says that his business model thrives on free competition, and that he doesn't believe that a walled garden would be good for Valve. And technically, too, Valve made open choices for SteamOS and Steam Machines, where they didn't have to.

Consider that Apple took a free OS as its base and have closed it: Valve makes it clear that it has no intention in restricting you from sideloading applications on SteamOS or installing whatever you want on your Steam Machine.

Valve might change in the future, but for now they are absolutely pushing an open platform.

First Bay Trail Windows 8.1 Convertible To Start At $349

emblemparade Re:This is what the Surface RT should have been (151 comments)

Yes, good point. But at least but they still render web sites properly, not something I can say about mobile Chrome. I would add a caveat, though, that browsing with touch is often a pain even with Android and iOS. So when I say "perfectly fine" I really mean "comparable," I'm looking forward to Metro support for Firefox coming soon, hopefully it won't be too dumbed down. I *need* AdBlock plus! Even mobile Firefox has a nice AdBlock add-on.

First Bay Trail Windows 8.1 Convertible To Start At $349

emblemparade This is what the Surface RT should have been (151 comments)

I'll repeat my title: this is what the Surface RT should have been. I would be happy to trade in my netbook + Nexus 10 tablet for one of these. And the price is very right, especially as it includes basic MS Office capability.

The Windows 8 interface is perfectly fine for a tablet. Worse in some ways than Android, better than others. The real advantage over Android is that you have a full web browser, none of those dumbed-down mobile versions that can't handle standard web sites. If you're really wedded to the Android app-world it's probably not so good for you, but remember that there's so much free Windows software that would do the job just fine. Android has been wanting full VLC and smoothly working Flash for years...

And as a netbook, it's the real deal. You can install *any* Windows software on it, unlike the Surface RT. And Bay Trail makes it that much more capable that the netbooks of old, that cost about the same, couldn't turn into tablets, etc.

People complaining about this being "slashvertisement" need to chill. This is news for nerds: a new category of consumer device that could really shake things up.
