If you own an iPod, you will know that other than storing music, you can also use it as an external hard disk. You simply connect your iPod to your computer and you can easily transfer files over via drag and drop. When it comes to the iPhone however, Apple sells you a larger hard disk, gives you more functionality, yet does not allow you to use it as an external hard disk. Come to think of it, the iPhone is the gadget that you are more likely to carry with you wherever you go and it is the more likely candidate to become a portable hard disk, yet you can’t do anything to it. If you are interested in knowing how you can use your iPhone/iPod Touch as an external hard drive, here are some ways that you can get it done.

One of the biggest problems still plaguing the environment today are the mass amounts of electronics being tossed out on a daily basis

Redis is a key-value database. It is similar to memcached but the dataset is not volatile, and values can be strings, exactly like in memcached, but also lists and sets with atomic operations to push/pop elements.

“Redis is a key-value database. It is similar to memcached but the dataset is not volatile, and values can be strings, exactly like in memcached, but also lists and sets with atomic operations to push/pop elements. “In order to be very fast but at the same time persistent the whole dataset is taken in memory and from time to time and/or when a number of changes to the dataset are performed it is written asynchronously on disk. You may lost the last few queries that is acceptable in many applications but it is as fast as an in memory DB (beta 6 of Redis includes initial support for master-slave replication in order to solve this problem by redundancy).”

I spent more time working on SSDs that weren’t the X25-M than the Intel drive itself. The Intel drive just worked as it should, the rest of them didn’t.

Fascinating article on SSDs. Until now, I have been aware of SSDs but largely ignored them due to cost-per-gigabyte for this heavy-duty data user. They're starting to get interesting. I doubt my _next_ drive will be an SSD, but the one after that probably will be. Given these sequential read/write numbers, I do look forward to putting my Aperture library on an SSD.

Best article about SSD technology ever written.

We are on the edge of two potent technological changes: Clouds and Memory Based Architectures. This evolution will rip open a chasm where new players can enter and prosper. Google is the master of disk. You can't beat them at a game they perfected. Disk based databases like SimpleDB and BigTable are complicated beasts, typical last gasp products of any aging technology before a change. The next era is the age of Memory and Cloud which will allow for new players to succeed. The tipping point is soon. Let's take a short trip down web architecture lane: # It's 1993: Yahoo runs on FreeBSD, Apache, Perl scripts and a SQL database # It's 1995: Scale-up the database. # It's 1998: LAMP # It's 1999: Stateless + Load Balanced + Database + SAN # It's 2001: In-memory data-grid. # It's 2003: Add a caching layer. # It's 2004: Add scale-out and partitioning. # It's 2005: Add asynchronous job scheduling and maybe a distributed file system. # It's 2007: Move it all into the cloud. # It's 2008: Cloud +

What makes Memory Based Architectures different from traditional architectures is that memory is the system of record. Also discussed Jim Starkey NimbusDB

article about data architecture for facebook's photo system. Seems interesting

The Photos application is one of Facebook’s most popular features. Up to date, users have uploaded over 15 billion photos which makes Facebook the biggest photo sharing website. For each uploaded photo, Facebook generates and stores four images of different sizes, which translates to a total of 60 billion images and 1.5PB of storage. The current growth rate is 220 million new photos per week, which translates to 25TB of additional storage consumed weekly. At the peak there are 550,000 images served per second. These numbers pose a significant challenge for the Facebook photo storage infrastructure. NFS photo infrastructure The old photo infrastructure consisted of several tiers: * Upload tier receives users’ photo uploads, scales the original images and saves them on the NFS storage tier. * Photo serving tier receives HTTP requests for photo images and serves them from the NFS storage tier. * NFS storage tier built on top of commercial storage appliances. Since each ima

Since each image is stored in its own file, there is an enormous amount of metadata generated on the storage tier due to the namespace directories and file inodes. The amount of metadata far exceeds the caching abilities of the NFS storage tier, resulting in multiple I/O operations per photo upload or read request. The whole photo serving infrastructure is bottlenecked on the high metadata overhead of the NFS storage tier, which is one of the reasons why Facebook relies heavily on CDNs to serve photos. Two additional optimizations were deployed in order to mitigate this problem to some degree:

I'm quite happy with that fact that the first piece of furniture I built is a bookshelf. I wanted to make something large enough to keep all my books, and stylish at the same time. The design I like is somewhat futuristic, with plenty curved lines and you can see that in this shelf. Generally it looks as if it was a part of the wall, or came out of the wall.

If you're looking for some budget-friendly shelving, this DIY solution will definitely look more elegant in your living space than some shop shelves from the hardware store. This particular mortise style shelving unit requires less wedging but a finer use of a saw blade—assuming, of course, you want the really cool wave in your vertical braces. The entire project requires nothing more than a few boards, long screws, a drill, and a jigsaw. Paint or varnish is optional, depending on the cut and quality of wood you use a simple clear coat might suffice. The entire affair is held against the wall with only three screws, the bottom of the braces rest on the floor to distribute the load, and the screws are hidden within the mortise joints. In regard to the stability and strength, the author of the Instructable SimonF notes that since he wrote the tutorial and took the photo you see here he has loaded even more stuff on the shelves without any issues.

The first one is to use an in-memory data store, and communicate using the memcached protocol. This is, of course, *exactly* comparable to Memcached — behaviorally indistinguishable! — and it does worse. The second option is to do that, except switch to an on-disk data store. It’s pretty ridiculous that that’s still the same speed — communication overhead is completely dominating the time. Fortunately, Tyrant comes with a binary protocol. Using that substantially improves performance past Memcached levels, though less than a direct in-process database. Yes, communication across processes incurs overhead. No news here, I guess.

No to SQL? Anti-database movement gains steam

The meet-up in San Francisco last month had a whiff of revolution about it, like a latter-day techie version of the American Patriots planning the Boston Tea Party. The inaugural get-together of the burgeoning NoSQL community crammed 150 attendees into a meeting room at CBS Interactive. Like the Patriots, who rebelled against Britain's heavy taxes, NoSQLers came to share how they had overthrown the tyranny of slow, expensive relational databases in favor of more efficient and cheaper ways of managing data. "Relational databases give you too much. They force you to twist your object data to fit a RDBMS [relational database management system]," said Jon Travis, principal engineer at Java toolmaker SpringSource, one of the 10 presenters at the NoSQL confab (PDF). NoSQL-based alternatives "just give you what you need," Travis said. Open source rises up The movement's chief champions are Web and Java developers, many of whom learned to get by at their cash-strapped startups without Ora

No, not SHARED lessons, I mean SHARD lessons. I have to admit that until about a year ago I didn't really know the term shards in relation to databases. Now don't confuse that with not understanding how databases can be horizontally scaled. I was introduced to that concept and helped to define the various ways it can be done but we just called it splits. Regardless of what you call it, there are some interesting challenges that are introduced. The well known challenges of consistency are discussed ad nauseam, even by me, so I'm not going there with this article. But besides that, there are some other lessons to learn when applying the pattern to your data.

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business. Amazon RDS gives you access to the full capabilities of a familiar MySQL database. This means the code, applications, and tools you already use today with your existing MySQL databases work seamlessly with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period. You also benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your relational database instance via a single API call. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources you use.

There's one simple rule about backups that everybody needs to fully understand: Your files should exist in at least Two places, or it's no longer a backup—and your data is at risk.

500 Internal Server Error

At Directi, we are taking a hard look at the way our applications need to store and retrieve data, and whether we really need to use a traditional RDBMS for all scenarios. This does not mean that we will eschew relational systems altogether. What it means is that we will use the best tool for the job – we will use non-relational options wherever needed and not throw everything at a relational database with a mindless one-size-fits-all approach. ... ... This post covers the current landscape of the NoSQL space. In a subsequent post, I intend to cover in more detail the various problem areas addressed by NoSQL systems and the specific algorithms used.

この記事をもっと早くに知りたかった。SkyDriveは容量的に問題はないが、接続にやや難がある。他のサービスに手を出すにしても、データの飛散が進んで逆に管理しきれなくなるのではないか?と危惧してみたり。

今回ピップアップするサービスは「Oosah」「Dropbox」「SkyDrive」「quanp」「firestorage」の５種類。

ワードやエクセルの軽いファイルならば、メールに添付して送れっても問題ないが、画像をふんだんに使ったＰＤＦやパワーポイントのファイルは数十メガバイトの大容量になることも珍しくない。社内や社外の人と共有したくても、メールでそのまま送るのは迷惑だし、そもそも受け取れないかもしれない。そんな時に便利なのが「オンラインストレージ」だ・・・

いまさら感たっぷりですが、Dropboxがいい感じです。「このフォルダの中身は、どのPCから見てもいつでも一緒」という安心感がたまりません。メインのPCで作業をしつつ、ノートPCを持ってイベントに行けばさきほどまで作業していたファイルにすぐにアクセスできます。 今までこうしたファイルはUSBメモリに移して（もしくはGmailで自分に送る）いたのですが、最近はめっきりUSBメモリを使わなくなりましたよ！ 複数のPCを持っている人じゃないとあまりピンと来ないかもしれませんが、メインPCとノートPCなんかを使い分けている人は是非導入してみてはいかがでしょうか。 db_files.gif ↑ 普通のフォルダと同じように使えます。同期が終わっているファイルはこのように緑のチェックマークがつきます（同期中のものは青いアイコンになります）。 その他にもいいことたくさんありますよ！個人的にぐっと来たポイントをつらつらと。 * 履歴が残る 昔のバージョンもまとめて管理しておいてくれるので「あの古いバージョンに戻したい！」というときに便利ですね。プレゼンファイルとかに威力を発揮するのでは。 db_revision.gif ↑ 保存するたびに履歴が。 * ウェブからも見れる ウェブにも同じファイルが残るので、バックアップ的な意味合いで安心です。最悪ウェブにあるでしょ、という安心感があれば、「同期作業きちんといっているかな・・・」というストレスが減るというものです。 * 削除したファイルやフォルダも見れる 削除されたファイルやフォルダも復元可能っぽいです。今のところすべての削除されたファイルを保管しているようですね・・・。 db_delete.gif ↑ いざというときに便利っす。 * フォルダ単位で他の人と共有できる あるフォルダだけ他の人と共有することもできますよ。共同作業をしているときに便利。 * Public Linkもあるよ フォルダを共有する場合はDropboxユーザーに限られますが、非Dropboxユーザーとも共有したい場合がありますよね。そうした場合はウェブから誰でもアクセスできる「Public L

"RAID" is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. The different schemes/architectures are named by the word RAID followed by a number, as in RAID 0, RAID 1, etc. RAID's various designs all involve two key design goals: increased data reliability or increased input/output performance. When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk.

Google Drive, or Gdrive as it is better known, has to be the most anticipated Google product so far. When it arrives, Gdrive will likely cause a major paradigm shift in how we use computers and bring Google one step closer to dethroning Windows on your desktop.

Apple has promised similar desktop, mobile and web file syncing between Macs, PCs and iPhones via a MobileMe cloud service, but the feature was delayed due to ongoing MobileMe difficulties - even though Apple built it into its desktop. Called "Back to my Mac," this OS X Leopard feature pairs with MobileMe online storage to let you search, access and edit files stored on a remote Mac. Besides such offerings from industry heavy-weighs, there are similar free or low-priced online storage services from others that let you do more or less the same.

Do we really want to store private data with a third party, even if it is Google?

Google Storage for Developers is a RESTful service for storing and accessing your data on Google's infrastructure. The service combines the performance and scalability of Google's cloud with advanced security and sharing capabilities. Highlights include:

"Getting a NAS set up as a simple file share is mostly a plug-and-play process. (More on that here.) And in raw form, it's a dead-simple concept: Here's a bunch of storage space that you can share among your home computers, over the network. But with a little work, you can do so much more than that, converting your NAS from a begrudging purchase in the name of caution to a vital piece of your very computing existence. Here are some of the best tips:"

The jQuery offline plugin provides an easy mechanism for retrieving JSON data from a remote server, and then caching it. Subsequent requests for the same URL will retrieve the data from the cache, rather than the remote server. If the user is online, the plugin will transparently request new content from the remote server, firing the callback again if the content has changed. If the user is offline, the plugin will request the data from the remote server for the most recent request when the user comes back online.

Web applications that wish to work robustly in flaky or offline scenarios can use client-side persistence to serve stale data while transparently trying to reconnect for more up-to-date data if possible. In a mobile scenario, the user may consider himself “connected” when in fact he has dropped out of connectivity for a moment (for instance, he may have gone under a tunnel). Because of this, and because latency on mobile devices can be quite high, a well-behaved mobile web application (or even simple website) will serve up content out of a local cache, so the user can see it quickly, before trying to make a connection to retrieve new content
