Double Up your UE BOOM speakers – Wirelessly Expand the Sound

Double Up your UE BOOM speakers – Wirelessly Expand the SoundUPDATED ON MAY 25, 2014 BY TUAN DONot long ago, I reviewed the UE BOOM speaker and it is still my favorite wireless speaker so far. It is water and stain resistant, it has a portable design that you can bring anywhere, its battery life is almost the longest one and its sound quality is better than all wireless speakers at the price range.In the review, I mentioned an interesting feature that I didn’t have a chance to try. That is the Double Up feature which allows wirelessly connecting two BOOM units to double the sound.Basically, you will need two BOOM speakers to try the feature. I connected the first speaker via Bluetooth and it acts as a master speaker. Then I installed the UE BOOM app which can be found on Google Play or App Store. The app is very clean and easy to use, you can also use this app to change Equalizer settings and set alarm. Here we will just use the Double Up feature. The app will require you to connect to the second speaker by pressing twice on its Bluetooth button. That’s the whole setup process. You just need to set up once, it will remember each other and automatically double up your sound next time. You can check out the video below for more details.The app offers 2 modes in the Double Up feature, which are Double and Stereo. In the Double mode, two speakers will play the same sound, so it will be suitable for large environments like party or outdoor use. The Stereo mode is where you can enjoy stereo sound as two speakers will act as left and right channels. I really love the Stereo mode as it really unleashes power of the wireless speaker. It makes the bass more powerful and the sound stage becomes much wider.

Amazon.com: Customer Reviews: MXL AC404 USB Conference Microphone

MXL AC404 USB Conference Microphone ElectronicsI use this mic to capture the voices from meetings in a conference room. I run Camtasia to capture the video portion of a slide or other computer/projected presentation and the audio portion from the mic and then encode it and store the movie on our corporate file server for future viewing. The conference table is 30′ long. Since the mic has 180 degree coverage, I place the mic close to one end of the table pointing towards the other end. It is very sensitive and has good frequency response. I adjust the record level using the computer audio mixer controls or the audio level control in Camtasia. Due to the wide frequency response range of this mic, it will also pick up AC noise, but I use the filters build into Camtasia to get rid of that frequency range. You could also use any other goood audio editing program such as Audacity no costto do this. Highly recommended.

Flip-Top Dell Inspiron Duo Makes a Terrible Tablet | Gadget Lab | Wired.com

The biggest problem is the price. As specced, you’ll need to pay $550, plus another $100 for the JBL speaker dock (which also adds ethernet and more USB ports). This computer seems little more than a cynical cash-in, a product trying to get in on the current tablet hotness without actually making a proper tablet.

activate more than one core in Mathematica 6.0 (for win)? – comp.soft-sys.math.mathematica | Google Groups

Now in Mathematica 5.2 you could set the number of threads using the

operating system environment variable OMP_NUM_THREADS so I tried

setting this to 2 to see what happened – nothing!  The time stayed the

same.  However if I set it to 1 then the timing came out at 8.9

seconds.  This leads me to the conclusion that Mathematica 6

automatically makes use of multiple cores when it can but you can over-

ride its behavior using OMP_NUM_THREADS,

Asus Eee PC 1015PN review

Battery life will also probably vary depending on whether WiFi and Bluetooth are enabled. And you can improve battery life by using the Asus Super Hybrid Engine to underclock the CPU by enabling “Power Saving Mode,” although in my tests the computer felt much slower when surfing the web with 5 or 6 browser tabs open in this mode — something that I hadn’t really noticed when using the Super Hybrid Engine on other Asus netbooks.

Acer Aspire One 521 review

On the other hand, the extra power comes at the cost of battery life. While the Acer Aspire 521 can run longer on a charge than some earlier notebooks with AMD chips, it doesn’t come close to netbooks such as the Asus Eee PC 1001P and Dell Inspiron Mini 10 in the battery life department. And while it outperforms a typical netbook in most performance tests, the Acer Aspire One still isn’t exactly a speed demon. Most users will probably find it makes more sense to pick one up for use as a secondary computer than as a primary machine.

Intel Atom N550 Notebooks – AnandTech :: Your Source for Hardware Analysis and News

The reason these CPUs weren’t used in netbooks—excepting a few ASUS models like the 1201N and the upcoming 1215PN—is the TDP and lack of power saving features. At 13W the 330 and D510 run too hot and consume too much power for practical implementation compared to the 5.5W N450. Add on to that the lack of SpeedStep, so the CPU runs at a constant 1.6GHz/1.66GHz, and as we measured on the 1201N battery life takes a serious dive. The new N550 fits somewhere between the N450 and D525 at 8.5W, but Intel claims battery life will be unaffected over the N450 thanks to power savings elsewhere—i.e. the use of more power friendly DDR3 RAM compared to DDR2 RAM.

Asus Eee PC 1015PN review

The Asus Eee PC 1015PN may be one of the most powerful 10 inch netbooks with an Intel Atom chip on the market today. Unfortunately with great power comes great less than stellar battery life. While the Eee PC 1015PN can handle 1080p HD video playback and some 3D graphics and gaming tasks, those capabilities come at the expensive of battery life, and you’ll be lucky to get between 4 and 6 hours of run time depending on how you use the laptop.

Intel Atom D510 Review, Performance, Etc. Round-up- Netbooks & Small Form Factor Computers | Small Computing

Intel Atom D510 — dual-core, TDP of 13w

Intel Atom D410 — single core, TDP of 10w

Intel Atom N450 — single core, TDP of 5.5w

All three of the CPUs are hyper-threaded, meaning they can execute on twice as many threads as there are cores, and of the three, only the Intel Atom N450 is the likely candidate for netbooks because of the power consumption (somewhat ridiculous considering they’re all quite low, but for netbooks, you need really low).

However, between the (forgiveable) missing media drive and the (inexcusable) missing TV capture solution, I really can’t recommend this for use as an HTPC, in full or part, because it makes this device pretty limited. Technically, if you have digital cable, you could get a remote dual-tuner (http://www.amazon.com/gp/product/B0010Y414Q?tag=a52-20&ie=UTF8). Otherwise, about all you be able to do is use it more as a media extender for another PC already set up to act as the main media server/TV-capture source. Of course, if you’re only after this unit for use as a media extender, it may just suit your needs perfectly. Be sure to snag a good media-center remote (http://www.amazon.com/gp/product/B00123UGWQ?tag=a52-20&ie=UTF8) if that is indeed the case. From my experience and perspective Zotac is great at making gear *almost* good enough to be used as an HTPC.

Intel Atom D525 vs. D510 – Pineview Processor Battle – D525 vs. N270 vs. ULV | TechPinas : Philippines’ Technology News, Tips and Reviews Blog

To ensure that the full CPU power of a PC system is realized, PerformanceTest runs each CPU test on all available CPUs. Specifically, PerformanceTest runs one simultaneous CPU test for every logical CPU (Hyper-threaded); physical CPU core (dual core) or physical CPU package (multiple CPU chips). So hypothetically if you have a PC that has two CPUs, each with dual cores that use hyper-threading then PerformanceTest will run eight simultaneous tests.
