oVirt 3.4 Means Management, VMs Can Live On the Same Machine
Common inexpensive server machines are very powerful today. Many cores, many GB of RAM. It becomes a management and flexibility nightmare to host all the desired servers on a single operating system.
For example, group A needs a web app hosted in a Tomcat environment; B needs a a JBoss based app; C and D need two different Django apps; E and F need Rails apps.. All of those apps together still only need 10% of the resources of the server. So, you can also host 20 other services on it. Good luck managing the dependencies across all the apps. Try upgrading libraries used by multiple servers. You're stuck with the lowest common denominator. Now add in the fact that group J and K want an app supported in Windows Server 2003, and L and M want Windows Server 2012.
In a VM environment, you can isolate each server into its own OS, with its own minimal set of needed libraries, and you need only manage and test how it works with the single hosted app. You can also bolt on more resources by throwing another server in the cluster and distributing the load.
TL;DR: Servers today are really powerful. You can be very resource inefficient to gain a ton of operational efficiency.
US Navy Strategists Have a Long History of Finding the Lost
They mention looking at the causes "terrorism, pilot error, sudden depressurization and engine failure" to estimate likely search locations. Of course, that's true.. But, if the cause is a rogue pilot who doesn't want to be found (as evidenced by the manual disabling of communications) things get tough really quick.
I guess at that point you're working with the fuel radius and removing areas covered by some form of tracking that would have definitely detected them.
Intel Rolling Out 800Gbps Cables This Year
This tech looks cool. But, it's a bit surprising to me that we've not had any leaps in basic networking for a long time. Everything is gigabit ethernet. I thought 10Gbps Ethernet would have trickled down to some home usage by now.
A 10Gbps connnection to my NAS, hypervisor, or server would be very useful. Or, just an uplink between switches.. But, I've not seen anything available.
Ford Dumping Windows For QNX In New Vehicles
I have an aging '08 Ford, and the Sync system is quite impressive. It has good bluetooth integration with smartphones, voice control of everything and works quite well even compared to new systems in cars sold today.
But, not long after the early success, they added more infotainment bells and whistles and started having reliability problems with Sync. This is at the time that they were releasing new models that had really good reliability ratings mechanically, but they were getting dinged badly for the Sync problems. I'm surprised it took them this long to move on to a new partner.
I like QNX, but given all the uncertainty about Blackberry's viability, it's surprising that Ford would choose them as the partner.
Electric Cars: Drivers Love 'Em, So Why Are Sales Still Low?
98% of the driving I do work great with a basic EV. My daily commute is no problem. The vast majority of other common trips fit comfortably in its range. But, the other 2%.. a round of golf two hours away or a weekend ski trip are dealbreakers. Keeping an EV plus a basic gasoline vehicle is an option, but creates a lot of logistical issues for parking, storage, insurance, etc.
Mountain View To Partially Replace Google Wi-Fi
Yes, I would also like Google Fiber. But, to say they never give back is a bit harsh.. Google wireless was an attempt to give free WiFi. It sucks, and I never use it. But, it was a legitimate attempt. I'm sure they discovered that to do it right it would be prohibitively expensive, and so they let it languish. But, they're not a charity.
Mountain View To Partially Replace Google Wi-Fi
I can confirm. There is an AP on a light post just across the street from my house. When I first moved in in 2008, I tried to use it and found it to be very poor. Trouble getting an IP, trouble authenticating. It was slow at low times. In the evening, it was unusable - I'm guessing because of overload at some point in the network.
Why Apple Went 64-Bit With the iPhone 5s
Why would this be power inefficient? They're not running ESX underneath iOS, it would be more akin to a microkernel doing low level memory segmentation. It shouldn't make much difference in CPU/Power. But, it will be less memory efficient.
I don't think jailbreak protection was the big driver. But, there IS a huge push in the enterprise realm for split devices. A tablet/phone that has a hard separation between personal use and corporate use solves a lot of issues. Keep data separate. Enforce cumbersome security requirements only on the corporate side. Allow remote policy enforcement, data deletion, encryption mandates, on the corporate side. In other words, make the corp side hard to use without effecting my personal experience. If the new architecture enables this, it will be a huge win for business use.
Tiny $45 Cubic Mini-PC Supports Android and Linux
This looks like it would make a great DVR frontend device IF it has usable video acceleration. The summary says that it does, but there is a huge difference between hardware capable of a feature and functioning Linux support for it.
What video formats does it support? Only H.264, like most recent devices? Or, will it do MPEG2 (the U.S. broadcast HDTV standard)?
Does it have Linux drivers for the video acceleration? VDPAU API support?
There are tons of devices out there that look great on paper, but very few that are usable in reality. If this turns out to work, I'll buy a few of them. But, I'll wait for that to be proven before jumping in.
First California AMBER Alert Shows AT&T's Emergency Alerts Are a Mess
My phone made an awful, loud, startling noise. I had never heard it before, and it scared the crap out of me. It sounded like a fire alarm. Once I realized it was my phone, my first thought was some sort of disaster requiring evacuation. Once I saw the message, it was only confusing. No real information, no linkage to details.
A google search turned up more about the Amber alert, which I discovered was several hours away from me in Southern California. I'm in Northern California. The details on the web mentioned that they were suspected of escaping to Texas. So, it was absolutely irrelevant to me. I immediately looked into how to disable it, and had it disabled in a couple minutes. 75% of the others I talked to today also disabled there Amber alerts.
1. The alarm should be more moderate, or at least adjustable. It was very startling. If I had been driving when it went off, I think the effect would have been dangerous. I would have left it on if I could disable the audio alarm and just get the message.
2. It needs more information, or at least a simlpe click-through to details, location radius / distance from me, pictures of the people involved, etc.
Ask Slashdot: Setting Up a Wireless Catch-and-Release
Get a new wireless access point. Many new models include what you're looking for. They appear as if they are multiple Access Points. Make two networks:
ChurchBusiness: WPA2 security, user accounts or strong password; full access to internal network
ChurchGuest: Security either as WPA2 password, or no wireless encryption and web redirect to authentication page; has only access to Internet, no church net access.
Many new routers under $200 have the ability to do the above. The Apple Airport Extreme can do the above, as can various Netgear or Linksys. Pick one up at a local retailer, give it a try.
DigiTimes Lends Credence To Apple-Branded TVs For 2012
Apple is not going to enter a market that is already in an aggressive price reduction war. Just look back at their same reasoning for not messing with Netbooks. If they can come in with a way to redefine the market, they would do that. But, not a "me too" television. Many/most other TVs have competitors to TV + Apple TV. Most suck, but they are still close enough to not allow Apple to price the TVs how they want, meaning they won't get in the market.
In the past, I thought they might do a next-gen Apple TV with integrated HD DVR. But, that's another fully saturated market bundled with cable/satellite services. Tivo has been unsuccessful in exploiting that market, so Apple will probably not go there. They could do iOS integrations, like auto-converting content to iPod/iPad/Mac friendly format. But, that would compete with iTMS purchased content. So, it's a no-go.
So, I think that this, like most Apple rumors, is rubbish. It's just someone's "how can I drive traffic to my www site? I'll make up the next possible step for existing apple technology."
Mozilla Contemplating Five Week Release Cycle
Mozilla gets money from advertisement, a well documented example of this is the $$ from google searches via Mozilla's search bar.
So, it's like TV advertisement. It's only worth money if you get a lot of eyeballs. Keep pissing off your users, and they will go elsewhere. As your market share decreases, advertisers willingness to pay you goes with it.
Ask Slashdot: Good Gigabit 802.11N Home Router?
I also use the RT-16. It was at the top of the list in terms of CPU Speed, RAM size, and Flash size when I bought it. It has a gigabit switch, which not all the devices in this class do. It also has 2 USB ports, for storage, printer, etc.
The one drawback was that it only does N at 2.4GHz, no 5GHz support. But, I already had a 5GHz N WAP, so I was just looking for a new switch/router.
Best Buy Releases Their Own Music Cloud
I hope they offer some sort of product replacement plan, so that if anything happens to my mp3 they'll give me the latest model of the bits as a replacement. That would really set them apart from Apple.
Flight 447 'Black Box' Decoded
Nova had a program on Flight 447, which I watched several months ago. I am not a pilot, and I'm going from memory.. but what I recall seems quite close to the new black box data. Their theory focused on the Pitots freezing up, making the computer unable to fly the plane.
A difference from most comments here: I believe they said the Pitots were heated (wouldn't ALL pitots have to be? It's always freezing at altitude), but there was a super-cooling possibility with very pure water which could surpass the heating ability. The comments here sound like the pitots were not heated and/or known bad.
They also put a pilot in a flight simulator in that scenario -- lost air speed data, stall warnings -- and he had no problem controlling the aircraft and maintaining level flight.
Working Toward a Universal Power Brick For Laptops
Even simpler, use a silver Sharpie.
But, I have two other issues:
- I have devices I am no longer using because the P/S failed and I cannot get replacements. Some have odd currents/voltages, and are impossible to find. If the device is not being made any more, it's really hard to find replacements.
- Too many wall warts. A universal Power Supply with configurable tips & voltage/current that could power multiple devices would simplify many things.
Open Source Router To Replace WRT54GL?
I had a WRV54G, which I always hoped would get DD-WRT support. There were some attempts, but it never really got off the ground. The WRV54G had hardware IPSec support in the Broadcom chip it was based on.
I've never located another home wifi router which supported Linux and some form of VPN. IPSec or SSL-VPN would be nice. Anyone know of devices that can do this?
Netflix Streaming Arrives For the Wii
Netflix seems to count streaming views similarly to physical disc rentals, so they de-prioritize your disc rentals the same way as many have reported for people who run through a lot of discs.
I picked up a Samsung Blu-Ray player which supports Netflix streaming. I found the selection to be fairly poor, but because of the easy access I ended up sampling a lot of material. After digging a lot, I turned up some good options, like some Showtime series, and PBS Frontline episodes.
During this time I had actually decreased the amount of the Netflix mailed discs I was watching. Partly due to having the streaming, but mostly just form being too busy. Despite the low usage of discs, all the top 15 movies in my queue were in the "Very Long Wait" state. Comparing my queue to co-workers queues showed that theirs did not have anywhere near the same delays shown.
I've completely stopped using streaming. It's okay as filler material if it's a "free" service. But, it's definitely not worth it if it means no access to decent movies.
If iTMS gets a little better selection, I will gladly stop my Netflix subscription. I'm sick of the gaming of the queue.
iPad Will Beat Netbooks With "Magic"
"Magic" is a stupid way of phrasing it. But, all he's really saying is that a touch interface is a fundamentally different way of interacting with the device. Apple is hoping that this will be enough to get it to catch on.
I am among the skeptics on whether it will really be a better way to work. I think it will be a fantastic device for frequent travelers (not as a laptop replacement, but as a compact email/music/video/browsing/etc. device for use while in-transit). But, I don't know if it will be very useful outside that realm. My laptop serves me fine in most cases, my phone is great for others, I'm not sure the gap between is big enough to need filling.
But, I am totally onboard with Apple on the iPad being better than netbooks. These have always seemed like junk to me. Other than being cheap, they don't offer much. Poor performance, poor screen, poor keyboard. No thanks. If I want a laptop, I'll stick with a real laptop.
