Ask Slashdot: Hardware Accelerated Multi-Monitor Support In Linux?

bartoku Re:Get a Mac, it just works ... (278 comments)

The MacBook Pro Retina 15" can drive 3 external monitors.
I regularly have two 2560x1440 cinema displays through the thunderbolt/displayports and a 1920x1200 monitor through the HDMI port.

I wanted more though, and for less than $2K you can get a powerful multi-monitor Mac setup today.
With the hope of improved multi-monitor support in Mavericks and the 2013 Mac Pro months away and disappointing I bought a Mac Pro.
Got a good deal on eBay for a used Mac Pro 2009.
Two ATI Radeon HD 5770 and a NVIDIA GeForce GT 120 give me 8 displays in OS X.
I was hoping I could use my AMD FirePro W600 given the new Mac Pro will be using a variant of that GPU line, but could not get it to work in OSX.

White House: Use Metric If You Want, We Don't Care

bartoku Base 10 is gimp (1145 comments)

10 is only divisible by 2 and 5. Everything should be like time, divided into 60. 60 is divisible by 2, 3, 4, 5, 6, 10, 12, 15, 20, 30. That is why feet and inches are superior to meters and centimeters. Dividing a foot by 2, 3, 4, and 6 inches is much better than 2 and 5.

The Days of Cheap, Subsidized Phones May Be Numbered

bartoku Re: an interesting perspective... (329 comments)

Free to use any carrier.

Except two of the four largest carriers, Verizon and Sprint, and only the gimp part of the AT&T (no LTE).
Sure HSPA+ is lovely and more than an enough, but at best you can really only use 1.75/4 carriers, not any.
Not to mention all the second tier carriers and most the virtual carriers are not an option either.

The Nexus 4 upgrade needs LTE for AT&T (700/AWS), T-Mobile(AWS), and Verizon(700 C Block).
Sprint LTE is useless since they do not provide a SIM card.
Then at least you could claim 2.5/4 carriers, Verizon is only a half until they retire CDMA and proprietary drivers that come with it.
Thank you FCC for the C block being forced open.

Plus your Nexus 4 lost its home, back, and menu buttons to the concept of taking up my big beautiful screen with stupid navigation buttons taking us back to the dark ages of iOS interfaces.
The Nexus 4 also lost its removable battery and expandable storage.
The camera on the Nexus 4 is not even worth talking about.
There is a reason the device only costs $299, it is gimp.

Unfortunately the Nexus line peaked with the Nexus One it seems, I am still cradling both of mine with all the same carrier options as your Nexus 4.
Sorry I am just bitter, Google could have done so much better. The bar was set so high after the Nexus One and each year I am further disappointed.

iOS 6.1 Leads To Battery Life Drain, Overheating For iPhone Users

bartoku Re:Upgrade to 6.1? (266 comments)

I am pissed that the Nexus 4 does not support LTE.

I concur.

While I think it is great that Google released a high end phone for $300, I would gladly have paid the normal Nexus retail price of $650 for a Nexus 4 LTE.
Instead I have gone with the Galaxy SIII and a custom ROM to get an AOSP and LTE experience on 2012 hardware.

The inclusion of AWS Band 4 LTE the requires some hacking is interesting.
I was hoping for LTE 700MHz Band 17 personally.
What LTE frequencies would you want supported?

"There's Always Next Year", when the Nexus 5 will have:
4/17/13/7/3/12/25 band LTE and Penta-Band HSPA+
A high quality 16MP CMOS camera sensor with O.I.S and Xenon flash.
A 5" 1080P IPS screen.
A physical QWERTY keyboard as well as physical home, menu, back, accept call, end call, and camera shutter buttons.
Dual EasyPoint Joysticks.
Hey, I can dream!

It will be interesting to see if Google can pull off a multi-band LTE device at the $300-$350 price point later this year.
It seems LTE cannot be ignored given the inclusion on the iPhone 5 and the backlash of complaints (although Nexus 4 sales exceeded supply expectations still).

But if Google "must" include LTE, how will it do it?
Penta-band HSPA+ has been a great feature of the last two Nexus Devices (only took two next years to get that).
In addition to the GSM support, the inclusion of LTE Bands 17/4 would cover AT&T and T-Mobile.
Throw in LTE Band 7 and Canada carriers covered.
The CDMA/LTE Verizon Galaxy Nexus was a headache for Google due to the proprietary CDMA binaries.
But including LTE Band 13 and counting on the 700MHz C Block FCC open rules would allow Verizon LTE coverage.
However, that would be data only on the Red Devil Carrier.
Including LTE Band 25 is tempting, but Sprint does not offer up SIM cards for its LTE device since it has no 700MHz C Block rules to comply with like Verizon.
Looking outside of North America, including LTE Band 3 and Band 20 would complete LTE coverage in handful of Asian, European, African, and the Middle Eastern locations.

I could not find the exact seven bands that the Nexus 4 Qualcomm WTR1605L chip supports.
The WTRL1605L supported bands may reveal what the Nexus 5 would support.

Of course there are rumors that Google is creating an experimental wireless network in Mountain View.
Perhaps like Google Fiber we will see Google's own wireless network rolled out...

As 4G Seeps In, Verizon Offers Cheap(er) No-Contract 3G Plans

bartoku Re:I'm still grandfathered in on Unlimited Data (67 comments)

I did not know you could hop between Verizon phones so easily now.

Do the Verizon LTE SIM cards carry the credentials for the CDMA network transfer as well?
Or do you need to go in or call Verizon and tell them to transfer the CDMA provisioning to a new device?

Are there any LTE devices that operate on Verizon frequencies but are not from Verizon? CDMA devices?
Is that technically possible, or would Verizon block such a device despite the device accepting the Verizon LTE SIM and frequencies?

US Wants Apple, Google, and Microsoft To Get a Grip On Mobile Privacy

bartoku Re:Also... (103 comments)

Bummer you did not take the time to log in and defend your whining.
I am so far off topics it cannot hurt to keep feeding he trolls now.

Yes, because it's Google's core principle to help the struggling American economy.

Of course not, Google's core principle is help Google. A strong American economy helps Google.
Throwing away tax money on programs that stunt the economy by teaching the lower class to be dependent does not help the economy.

Please... Big companies don't give a damn about economy of any country - they only care about the economy of their business.

The economy of their business is tied to the economy of every country they operate it, they care whether they want to or not.
Again, they help the economy best by keep as much of their money as possible instead of wasting it on taxes.

If you offer them incentives to get out of tax heavens, they'll thank you dearly and start thinking of ways to import Chinese workforce into the US.

Lower minimum wage so that Chinese workforces are not so appealing.

Trickle-down economy means the rich and powerful pissing on everyone and everything below them.

If you lie on the ground with your hands out to the government then it is no surprise a little urine trickles down on you.

The happiest day in any CEO's life would be the day slavery is reinstated. Do you know why the minimum wage is the most common pay grade in Europe? It's not because the people are uneducated. It's because the companies can't lawfully make their wage any lower than that, and they would if they could.

Supply and demand, if you are not worth more than slave wages, what good does paying you an artificially higher wage do?
Nothing, it teaches you that less effort gets you more gain, sucking the tit of the government like a good little baby.

There's just no work here in the UK - the people are fighting for the PRIVILEGE of having a job. And that means a company can open a position for a minimum wage and not worry about people not showing up for the interview. Even better, they can open an "internship" position and get people flocking to their doorstep by simply saying "At some point in the future we might even offer you a paid job - depends on how long we can milk the current economic climate".

Then leave the UK or create your own job opportunities.
Why go work for the man if you are worth more?
In the states there are more job opportunities falling in my lap daily than 100 of me could do.
I can only imagine how many I can find if I looked.
Those who cannot find work are just plain lazy, expecting hand outs.

I say, if having a job is a privilege in itself, then there is something fundamentally wrong with the system.

Having a job is a privilege, has always been aprivilege, and should always be a privilege.
Those who believe they are entitled to anything automatically are the drain on system and the problem themselves.

And unfortunately you can't blame the clueless government on this one, even if it was a contributing factor.

You are correct, a culture of entitlement is to blame; those who think they deserve something for nothing have formed the government and the system that they complain about and bleed dry.

I love working with immigrants from countries such as China, Korea, Japan, India, Pakistan, Syria, Lebanon, and the like.
I have heard stories of them escaping horrible conditions, even wars, living on things as awful as cat food while working through school.
They work extremely hard and never complain for a moment about their hardships.
Instead they are just abundantly grateful that they have opportunity and liberty.
As a result I see them produce, create wealth, and become very successful.
Meanwhile spoiled little Europeans and Americans whine that they are not handed more.

Microsoft's Future of the Living Room Starring SuperTuxKart

bartoku Re:they needed source. (82 comments)

BUT.. if you had a projector, why the fuck use the tv.

Simple, the pixel density and picture quality from the LCD display will be better than the projector.

If you had a nice projector screen and a projector with a crazy resolution then by all means ditch the LCD display, but it will cost you a good amount and is not really novel.
However this solution can combine a sub $500 projector and sub $500 LCD display and provide a novel new display that increases immersion without compromising the current image quality.

I agree it is not exactly mind blowing, this is today tech, if not yesterday tech.
It is simply a matter of software support, the hardware is sitting at your local electronics store waiting to be purchased and setup in your living room.
However, it is clever, no one else bothered to do it that I have seen. Furthermore, I would be interested in seeing it in person or setting up my own version.
That being said, I would love for them to take this a minor step forward.
I would love to see four cheap projectors combined and strapped to the ceiling with an LCD in front.
Now the entire virtual world is around me, I am immersed in it; and still a potentially affordable solution.
Heck, I am going to Amazon.com right now to buy me some cheap projectors to build this setup and trump Microsoft!

Slashdot Asks: What would you like to see at CES?

bartoku Re:A phone running Ubuntu Mobile (102 comments)

We need carrier killing hardware and a carrier agnostic data radio tower setup.

The hardware would have an open boot loader ready to take on Android, Ubuntu, Jolla, and any other open sourced ROM available.
The hardware would include the five major HSPA+ bands (850, 900, AWS, 1900, 2100), and LTE bands (4, 17, 13, 7, 3, 25) to cover a majority of the spectrum used by carriers in the Americas, Europe, and the rest of the world.
The hardware would also support a USB dongle for additional carrier data support for carriers who do not provide SIM cards.

Beyond that the hardware will support a protocol for carrier agnostic mobile accounts.

Cell towers would run like WiFi access points, and the mobile device would handle the hand off between towers.
Each tower can even be run by an individual entity if desired, no national or regional carrier system would be needed.
Instead there would be entities that sell data credit to end users.

A mobile device would have an account with a data credit reseller.
The mobile device can scan for access in its area and connect to a tower based on how the user priorities (cost, speed, signal strength...)
The tower would then charge the data credit reseller for the user's usage.

This setup allows for each cell tower to compete for users in an area.
This would allow start-up wireless companies to compete immediately.
Once enough individual towers went up then it would compete with the big carriers and force them to change and join the carrier agnostic system further driving down the price for data for consumers.

Ask Slashdot: Do Coding Standards Make a Difference?

bartoku Re:After 42 yrs programming I say... (430 comments)

I'm not seeing the issue.

You are missing the point of the post by man_of_mr_e and the reply from casing.
man_of_mr_e wanted to dismiss formatting issues as not a big deal to diff in the version control, claiming diff is smart enough to handle it; an interesting assertion.
However, casing cleverly pointed out that man_of_mr_e was missing the issue of case formatting and how diff would probably choke on it.

If a dude is changing variable names, then I would want to know about it as that is less trivial than whitespace changes. This seems like another productivity issue. If I have a guy focusing on changing variable names from myVar to my_var, then he's either going to be talked to and told to wisen up or canned as he's not doing anything productive.

I agree that if productivity is in question then it would be nice to know. However I would disagree that productivity issues should clutter a version diff though.

Imagine the scenario where my IDE can quickly switch code from camel case to snake case and give me the white spacing I am most comfortable with. If with a key stroke Bill can alter Joe's code to be more readable for Bill and that in turn improves his efficiency, then why not? Correspondingly then Joe should be able to flip it write back when he has to work on Bill's code.

Now you are worried about the situation where Bill picks up Joe's code and spends his morning moving curly brackets to a new line and converting camels to snakes manually. Probably not the best use of Bill's time for you, and even if arguably the time spent converting Joe's code manually makes Bill more productive it was not a total time well spent. Now surely Bill is good enough to read Joe's formatting, but if it pisses him off, well then perhaps a few hours is worth keeping Bill happy? I mean Bill is a good guy, a great programmer, he is just set a bit in his ways and opinionated. Bill is still making his deadlines, no worries.

Ask Slashdot: Do Coding Standards Make a Difference?

bartoku Re:After 42 yrs programming I say... (430 comments)

Personally if you have a coder using myVar and my_var for two different variables in the same code, I think you have more to worry about that coding style.

I believe he was referring to Joe using camel case, myVar, and then Bill later fixing it to snake case, my_var. As a result the diff would mark this change as a difference since it was more than a white space change. This is as opposed to Joe placing his curly brackets on the same line as his if statements and Bill moving them to the line below white space changes.

White spacing changes are no longer a big deal with modern IDE's able to reformat to your desired white spacing, but I have not seen an IDE option to correct camel case to snake case.

Nokia Dethroned As Top Phone Maker By Samsung

bartoku Re:Should have peed their pants (134 comments)

Nokia was big enough to bet multiple horses...

Agreed, if they truly believe in not selling out to something like Android they would have stuck with MeeGo which was just as far along as Windows Phone.

I really wonder what the thought process was behind dumping MeeGo and going with Windows Phone, if they truly saw it being a winner.
Unfortunately it seems there best bet now is to stay the course with Windows Phone.

I would kill for a 41MP PureView camera coupled with updated N950 hardware and running Android.
The smartphone market is so crowded, but a super phone is still waiting to be released.

I really hope the smart phone hardware market turns more toward a PC model of separating the hardware from the software.
Unfortunately Apple is trying to destroy that in both markets, and even more unfortunate it is a sound business plan.

I am putting together an electronics hardware lab and looking for suggestions on everything from equipment to furniture for the lab. My aim is for a professional grade setup, not just a hobby lab. The goal is to be able to test and debug modern electronic device prototypes. I would love to see money is no objective suggestions along side more economically practical solutions. Links or contacts for good distributors to acquire the equipment and furniture is also welcome. Also commentary on renting versus buying new or used higher end equipment to be economical and keep up with equipment that will become obsolete quickly."
