My boss was trying to do a thing using Windows 10. It wouldn't work. They asked me if <a href="http://ethosdistro.com/kb/#writing-linux">I could do it</a> under Xubuntu. Problem solved in short order.

<p><code>sudo port -v install smartmontools</code></p>
<p>Then run the query on the SSD in question.</p>

It turned out the horrible sounds were rice grains stuck in the fan, rather than a broken fan. I won’t bring up last year’s incident where someone in my household flooded the counter, resulting in my having to place my MBP in a box of rice for two weeks. What I didn’t know is that there were still some rice inside that must have shifted and got in the fan.</p>

Synchrotech lent me a <a href="http://www.synchrotech.com/products-thunderbolt/thunderbolt-sata-6gbps-hdd_ssd-drive-external-enclosure-delock-42513.html">Delock 42513 Bus Powered Thunderbolt External Enclosure for SATA 6Gb/s 2.5-in SSD/HDD</a>. It is billed as one of the first bus powered cases, and I am unaware of any others. I only had a Western Digital WDC WD3200BEKX-00B7WT0 320GB HDD on hand to test it. It mounted no problems, and the speed tests were in line with a hard drive of it's type. Bus power is a long overdue feature, but welcome nonetheless.

<p>
Synchrotech lent us one of their <a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-speaker-mono-m-520.html">M-520 speakers</a> to play with for an afternoon. The first thing that was apparent was that this device's fit and finish belied its under thirty dollar price tag. We were pleasantly surprised at the quality and feel, and the photos really don't do it justice.
</p>
<p>
We needed to charge the unit before using it. The included power adapter allows charging off a USB port, or a power outlet. We opted for the former and let the unit charter for an hour before putting it through the paces.
</p>
<p>
We took turns pairing it with our phones including my with my iPhone 5S, and another tester's HTC One. Connecting speaker was simple and straightforward. We were surprised at the sound quality and volume capabilities. While the <a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-speaker-mono-m-520.html">M-520 speaker</a> didn't output Bose or Klipsch quality audio, it certainly sounded good for a portable monophonic device—even at full volume.
</p>
<p>
What we liked best about the <a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-speaker-mono-m-520.html">M-520</a> was the price. At under thirty dollars, we'd be willing to bring it to the beach or leave it on a busy picnic table in the park, because we wouldn't be heartbroken if something happened to it. Our experience with the speaker made us hope that we'll get a chance to test out its stereo cousin, the M-530.

It's no secret that the bulky and awkward design of 'Micro' USB connectors has long been problematic—especially its unidirectional orientation insertion requirement. While not nearly as elegant as Apple's Lightning connectors, the new USB Type-C connectors promise better than the downright awful existing standard. According to the USB-IF <a href="http://www.usb.org/press/USB-IF_Press_Releases/Type-C_PR_20131203_Final.pdf">press release</a>:
</p>
<p>
Key characteristics of the USB Type-C connector and cable solution include:
</p>
<ul>
<li>An entirely new design tailored to work well with emerging product designs</li>
<li>New smaller size – similar in size to the existing USB 2.0 Micro-B</li>
<li>Usability enhancements – users will no longer need to be concerned with plug orientation/cable direction, making it easier to plug in</li>
<li>The Type-C connector and cable will support scalable power charging</li>
<li>Scalability – the connector design will scale for future USB bus performance</li>
</ul>
<p>
Several trade publications have covered this story.

If you're like me with Macs that have Thunderbolt with no USB 3.0, the <a href="http://www.synchrotech.com/products-thunderbolt/thunderbolt-sata-6gbps-hdd_ssd-drive-adaptor-with-ac-adapter-delock-61971.html">61971</a> is the perfect solution for 7200RPM 3.5 inch drive backups, and running a MacBook Pro off an external SSD. The portability of the 61971 is great for 2.5" HDD/SSD on the road, but it's power supply makes it useful when in a fixed location for backups to spacious 3.5" HDD. Be sure to keep an eye on this space for a future review!

<a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-a2dp-music-receiver-m-510.html"><img alt="Portable Bluetooth A2DP Music Receiver M-510" src="http://www.synchrotech.com/product-misc/img/aud_portable-bluetooth-a2dp-music-receiver-m-510.jpg" style="float: right; margin: 0em 0em 1em 1em;" title="Portable Bluetooth A2DP Music Receiver M-510" width="220"></a>Got a loaner <a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-a2dp-music-receiver-m-510.html">M-510 Portable Bluetooth A2DP Music Receiver</a> to test out over the weekend. We plugged it into a Bose Wave II Radio using the included double male 3.5mm stereo audio cable. Our test devices were an iPhone 3GS and an iPad with Retina display (4th generation). Both devices were running iOS 6.1.3. Getting the M-510 to work with iOS devices was a snap, and the sound quality was surprisingly good for typical mobile device playback.
</p>
<p>
The<a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-a2dp-music-receiver-m-510.html"> M-510</a> Portable Bluetooth A2DP Music Receiver supports the Bluetooth <a href="http://en.wikipedia.org/wiki/Bluetooth_profile#Advanced_Audio_Distribution_Profile_.28A2DP.29">Advanced Audio Distribution Profile (A2DP)</a> utilizing <a href="http://en.wikipedia.org/wiki/SBC_%28codec%29">Low Complexity Subband Coding (SBC)</a>. SBC is applied to existing audio CODECs, in other words transcoding on the fly. This is fine for typical medium to higher quality AAC and MP3 stored on portable devices like iPods, iPhones, and iPads. However, if you're expecting lossless formats like <a href="http://wiki.hydrogenaudio.org/index.php?title=FLAC">FLAC</a>, <a href="http://wiki.hydrogenaudio.org/index.php?title=Apple_Lossless">ALAC</a>, or even high quality lossy formats like lame <code><a href="http://wiki.hydrogenaudio.org/index.php?title=Lame">--preset insane</a></code> encoded files to sound the same, they won't. Highest quality audio is better served over WiFi with AirTunes/AirPlay enabled audio equipment. That said, the <a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-a2dp-music-receiver-m-510.html">M-510</a>'s quality is acceptable for 256 kbps or lower quality iTunes AACs or MP3 files, which is what most people have on iDevices and other portable players. Overall the M-510 is an inexpensive way to add wireless playback ability to devices without that capability. If you're looking for really high fidelity, you're not shopping the under $40 devices market to begin with.
</p>
<p>
The M-510 Portable Bluetooth A2DP Music Receiver's other big plus is that it provides the choice between an AC adapter and running off a single AAA battery. That last option provides a lot of flexibility when you think of portable scenarios. Don't want to lug your expensive audio equipment outside, but have an old boombox with a 3.5mm line in? Add the<a href="http://www.synchrotech.com/product-misc/aud_portable-bluetooth-a2dp-music-receiver-m-510.html"> M-510</a> and now that boombox becomes remote speakers for your iPhone 5.
</p>
<div class="separator" style="clear: both; text-align: center; border: gray thin dotted;">
<p>
Pairing the M-510 with the iOS devices is a simple as visiting Settings > Bluetooth" and then finding <strong>Music Receiver</strong> in the list of devices

They write about it <a href="http://www.everythinghereplus.com/support/biwins300xcompactflashtestedunderxubuntulinuxwithourdelock91694firewirecompactflashreader">here</a> and <a href="http://store-everythinghereplus.blogspot.com/2013/06/testing-biwins-300x-compactflash-under.html">here</a>. The CompactFlash cards they tested aren't of much interest for DSLR folks, so I won't post the actual benchmarks here. Those interested can check out the previous mentioned posts. They used the benchmarking feature of the linux app Disk Utility 3.0.2, and listed their test platform as follows.
</p>
<ul>
<li>Xubuntu 12.04.2 LTS</li>
<li>Intel Core2 6300 @ 1.86GHz with 2GB RAM</li>
</ul>
<p>
For older Linux systems without SuperSpeed USB 3.0, using FireWire 800 or even FireWire 400 is going to provide much better performance reading high end CompactFlash cards. The <a href="http://www.everythinghereplus.com/electronics/delock-91694-firewire-cf-compactflash-reader-firewire-800-ieee-1394b-udma">Delock 91694 FireWire CF CompactFlash Reader FireWire 800/IEEE 1394B</a> is an excellent piece of hardware. I'll try to get them to test some higher speed CompactFlash on their setup soon.

Hi!
</p>
<p>
I've just released <a href="https://github.com/maitria/gambit-objc">gambit-objc
0.1.0</a>. This is the "it has the basics, and the implementation is complete
enough for real projects" release.
</p>
<p>
* It gives you access to Objective-C class objects. The easiest way is:
</p>
<p>
<code> (import-classes (NSString NSDictionary))</code>
</p>
<p>
after which, you can refer to them.
</p>
<p>
* It dynamically dispatches Objective-C methods:
</p>
<p>
<code>(: NSString stringWithUTF8String: "hello, world")</code>
</p>
<p>
* It supports marshaling of native Scheme objects to C/Objective-C types for
parameter and return values, including structures, selectors, all integral
types, and UTF8 strings. It wraps Objective-C objects with foreign.
</p>
<p>
* It has a objc-repl, an extended version of gsi which supports square-brace
syntax, like so:
</p>
<p>
<code>[NSString stringWithUTF8String: "Hello, world!"]</code>
</p>
<p>
You'll find a minimal sample Cocoa app in the distribution as well.
</p>
<p>
There are many cool things that can be added. I'd love to collaborate, help
people use it, and otherwise enable its adoption.
</p>
<p>
I'm really happy with how elegant it ended up (after a couple partial
implementations were scrapped). My next focus will be making it easy to boot on
iOS and bring into iOS projects.
</p>

In <a href="http://synchrotech.blogspot.com/2013/03/automating-x4sd-usb-20-sd-card-reader.html">Automating X4SD USB 2.0 SD Card Reader Four (4) Slot Operations</a> Synchrotech outlines several techniques for automating the copying of files to the device's multiple slots. Here we explore making exact binary copies of media using the device. A common use of this process is duplication.
</p>
<p>
There's various ways to do do device duplication or byte-for-byte copies of media. Whether we're duplicating CD-ROMs, hard drive disks, <a href="http://www.everythinghereplus.com/support/u111-with-unix-like-systems">SRAM PC Cards</a>, or other removable media, the Unix <code>dd</code> is frequently preferred for these types of operations. While we can execute card to card duplications from one <a href="http://www.synchrotech.com/products/card-rw_41_x4sd-usb-2.0-sd-card-reader-four-4-slot.html">X4SD</a> slot to another, the most common use for the reader is to write an existing SD Card image to all four slots simultaneously. To that end we'll create a binary image of a master SD Card and then use that master to write to blank cards.
</p>
<h3>Creating an image of the SD Card</h3>
<p>
<code>dd</code> works with block devices, so we need to unmount the SD Card. To make this simple, we'll be using just one of the <a href="http://www.synchrotech.com/products/card-rw_41_x4sd-usb-2.0-sd-card-reader-four-4-slot.html">X4SD</a> slots at this stage. We'll be using Mac OS X for our example and detail the difference for OpenBSD and Xubuntu. First, we need to identify the mount point of the inserted card. Calling <code>mount</code> in the terminal shows us the information we need (we're leaving out the rest of the output here).
</p>
<pre>
<code>/dev/disk1s1 on /Volumes/NO NAME (local, nodev, nosuid)</code>
</pre>
<p>
We use that information to unmount the mounted device.
</p>
<pre>
<code>[kyoto:~/Desktop] rds% sudo diskutil unmount /Volumes/NO\ NAME
Volume /Volumes/NO NAME unmounted</code>
</pre>
<p>
OpenBSD and Xubuntu would use <code>umount /[devicepath]</code>. Using the block device reference to the <a href="http://www.synchrotech.com/products/card-rw_41_x4sd-usb-2.0-sd-card-reader-four-4-slot.html">X4SD</a> slot, we can copy the card to a binary file using <code>dd</code>.
</p>
<pre>
<code>[kyoto:~/Desktop] rds% sudo dd if=/dev/disk1s1 of=sdcard.bin
1951677+0 records in
1951677+0 records out
999258624 bytes transferred in 1203.276878 secs (830448 bytes/sec)</code>
</pre>
<h3>Writing the image to SD Cards</h3>
<p>
Inserting a new card into the <a href="http://www.synchrotech.com/products/card-rw_41_x4sd-usb-2.0-sd-card-reader-four-4-slot.html">X4SD</a>, then unmounting it, we can create a duplicate of the original. We then test it using <code>cmp</code> to see if it is identical to the binary file.
</p>
<pre>
<code>[kyoto:~/Desktop] rds% sudo dd if=sdcard.bin of=/dev/disk1s1
1951677+0 records in
1951677+0 records out
999258624 bytes transferred in 1203.276878 secs (830448 bytes/sec)
[kyoto:~/Desktop] rds% cmp /dev/disk1s1 ~/Desktop/sdcard.bin
[kyoto:~/Desktop] rds%
</code>
</pre>
<p>
Here we write to all four slots simultaneously on a Xubuntu machine. It's feasible that using hubs and multiple <a href="http://www.synchrotech.com/products/card-rw_41_x4sd-usb-2.0-sd-card-reader-four-4-slot.html">X4SD</a>, we could write to more than four cards at once on a machine with enough CPUs/CPU cores. However, there's a practical limit to the amount of I/O operations one would want to run at the same time. Perhaps writing to each bank of cards sequentially would be the best practice? Since I was only provided a single test unit, that remains an academic question.

Since I don't have a television at home with <acronym title="High-Definition Multimedia Interface">HDMI</acronym>, I borrowed an HDMI monitor as well.
</p>
<p>
I had never used an Android device before, but aside from some interface clunkiness, it wasn't too hard to navigate around on the device. While many people have touted the device's video playback, internet, and gaming abilities, I was far more interested in its potential as a power efficient music server.
</p>
<p>
At home I have a Bose Wave® radio II, but I don't always want to start a computer to use Soundlink—which inevitably requires a time consuming Bluetooth re-pair almost every time I use it. Nor do I always want to use with my iPod, which due to its capacity, has song file bit-rates that sound somewhat flat on the Bose. I've always wanted a reliable, but inexpensive music server with a wired connection to the Bose that had ample storage and a usable interface. Preferably with the capability to play <acronym title="Free Lossless Audio CODEC">FLAC</acronym> or <acronym title="Apple Lossless Audio CODEC">ALAC</acronym>. Synchrotech had already <a href="http://synchrotech.blogspot.com/2012/09/using-large-usb-hard-drive-with-mk802.html">tested the MK802 with USB Hard Drives</a>, so there's no worries about large music collections.
</p>
<p>
While the specifications for the <a href="http://www.synchrotech.com/product-misc/mini-pcs/mk802-android-4.0-mini-pc-smart-tv-player.html">MK802 Android 4.0 Mini PC</a> don't list FLAC as one of its audio <acronym title="coder-decoder">CODEC</acronym>s, the specifications for the Android 4.0 do, so the first thing I wanted to try was FLAC playback. It turns out that FLAC files play just fine on the device. I also tested a variety of MP3 and AAC files with the MK802. Things were looking pretty good at that point.

If there was one issue I had with the native Android audio player was that it didn't display the album artwork for any of the files tested. I asked a friend who has had a variety of Android phones and tablets and he said that he wasn't sure why that was happening, and suggested I try other music players like Spotify and WinAmp for Android. The former has problems with the screen orientation for the MK802 and promptly displayed its interface upside down. No matter what we did, we couldn't get Spotify to display correctly. Hope that's something that will get fixed in the future. We couldn't get WinAmp for Android to run at all on the <a href="http://www.synchrotech.com/product-misc/mini-pcs/mk802-android-4.0-mini-pc-smart-tv-player.html">MK802 Android 4.0 Mini PC</a>, even though we installed it via Google Play (née Android Marketplace). Any other suggestions for a robust music player better than the built in version are welcome. Displaying album cover art is pretty much a must considering it's a unit for TV display. A visualizer like the one in iTunes would be a nice bonus too. What did run well was Pandora, but unfortunately that doesn't give us the option to play our own files.

A frequently asked question about <strong>FireWire</strong> repeater hubs is "do I need the optional power supply?" The answer to this question depends on the types of FireWire 800 or FireWire 400 devices are being used.<br />
<br />
<strong>Quick Definitions: Self Powered vs. Bus Powered</strong><br />
<br />
<strong>Self Powered FireWire</strong> devices are ones that plug into the wall or utilizes internal batteries. One example is FireWire hard disk drives using 3.5in mechanism which come with their own power transformers and AC adapters. Another example are battery powered DV Camcorders. Most <strong>FireWire</strong> based audio equipment like those from Pro Tools is self powered as well<br />
<br />
<strong>Bus Powered FireWire</strong> devices draw current from the <strong>FireWire</strong> bus itself. FireWire hard disk drives using 2.5in mechanisms are typically able to use bus power. Our CFFire800 Pro FireWire 800 UDMA CompactFlash reader requires bus power. Portable devices like the Apogee Duet require bus power as well.<br />
<br />
If you are using self powered devices with a <strong>FireWire</strong> repeater hub, then there isn't a need to purchase an optional power supply. Conversely, if you are using bus powered FireWire products, you almost certainly need the optional power supply. [1]<br />
<br />
Bus Power isn't always enough for multiple devices drawing current off multiple ports at the same time. If you daisy chain several devices, it also may draw more current than available. Further, the total amount of Amps a hub provides needs to divided by the number of ports to find per port current when each port is drawing current. In the case of Unibrain's FireRepeater 3A supply, this would work out approximately as follows:<br />
<br />
<dl><dt><strong>Unibrain FireRepeater-800 Pro FireWire 800 IEEE 1394b Repeater Hub 5 Port</strong></dt>
<dd>(3 amperes) / 5 = 0.6 amperes approximately per port (max)</dd>
<dt><strong>Unibrain FireRepeater-800 Pro FireWire 800 IEEE 1394b Repeater Hub 4 Port</strong></dt>
<dd>(3 amperes) / 4 = 0.75 amperes approximately per port (max)</dd>
<dt><strong>Unibrain FireRepeater 800 FireWire 800 IEEE 1394b Repeater Hub 3 Port</strong></dt>
<dd>(3 amperes) / 3 = 1 ampere approximately per port (max)</dd>
<dt><strong>Unibrain FireRepeater 400 FireWire 400 IEEE 1394a Repeater Hub 3 Port</strong></dt>
<dd>(3 amperes) / 3 = 1 ampere approximately per port (max)</dd>
</dl><br />
Often computer companies will list ports by watts, instead of amps. When a company lists Watts for their <strong>FireWire</strong> ports, divide it by 12 (FireWire is typically 12 Volts) to find the Amperage.<br />
<br />
The calculation above are the worst case scenario, typical application rarely see devices drawing current of each port.<br />
<br />

[1] A notible exception was the CFFire800 Pro FireWire 800 UDMA CompactFlash reader with Unibrain's 3 Port FireWire 800 Hub. We've tested this off a powered Mac port and were able to run two CFFire800 Pro's without the addtional power supply. Here is a quote from our test results.<br />
<br />
<blockquote cite="everythinghereplus@everythinghereplus.com">While our CFFire800 Pro uses <strong>FireWire</strong> bus power, we knew it draws less than 500mA, while the MacBook Pro provides just under 1A of current while running on batteries. One product we offer, Unibrain's extremely portable FireRepeater 800, splits source current between two ports. With that in mind we set out to test two CFFire800 Pro readers with FireRepeater 800 to see if it provided enough power off a single FireWire 800 port to enable both CompactFlash readers; we found it worked flawlessly.<br />

How handy is this photo? It sure makes a lot of prose unnecessary. These adapters cover just about any FireWire 400 or FireWire 800 conversion scenario one could think of.<br />
<br />
<a href="http://www.everythinghereplus.com/electronics/firewire-800-and-firewire-400-cable-converter-and-adapter-plugs">Converter plugs</a> for FireWire cables allow changing the cable plug type at the very end to match that of the port it's being plugged into. For FireWire 400 (IEEE 1394a) ports, there are converter plugs allowing 9-pin cables to plug into 6-pin ports and converter plugs allowing 6-pin cables to plug into 4-pin ports. For FireWire 800 (IEEE 1394b) there is an adapter plug allowing 6-pin cables to plug into 9-pin ports.Robert D.

<a href="http://www.everythinghereplus.com/">EverythingHerePlus.com</a> recently announced a first draft of a document which outlines the use of the BSD and Linux compatible USB reader for PCMCIA PC Card SRAM and ATA Flash memory devices. While the draft isn't complete, experienced users will have no problems using the command line instructions to complete tasks. They tested the device with OpenBSD and Xubuntu Linux.<br />
<br />
<a href="http://www.everythinghereplus.com/support/u111-with-unix-like-systems">Elan's U111-M PCMCIA PC Card reader for SRAM and ATA Flash memory devices</a> is unique in that the reader itself brokers all the interfacing with the PC Card and presents itself to the host computer as a USB mass storage device. In addition to working on The Windows platforms, the device works with various versions of BSDs and Linux. Because of this, the U111-M allows users of Unix-like platforms to perform actions on these cards using common command line tools that usually require specialized and expensive software for The Windows. EverythingHerePlus hopes the document will be helpful to those wanting to deploy the U111-M with Unix-like systems.<br />

Since I usually use NFS instead of samba, I hadn't noticed that <a href="http://www.openbsd.org/">OpenBSD</a> had changed the password back-end for samba. This was with 4.8-current, although they might have changed things earlier without me noticing. In fact, it may well have been a samba change rather than an OpenBSD specific one.<br />
<br />
Regardless, the new configuration isn't any harder than the previous incarnation, just different. Took all of one minute to get things working again.<br />
