IP Networking Unix Open source Linux storage

shared by David Corking on 25 Apr 09 - Cached
  • this datacenter systems market is more than $150b annually. And in this datacenter market we build exceptional systems
  • storage, from our new flash based platforms to eco-efficient tape and archive solutions.
  • more than just naked components, they're engineered with remote management and monitoring, component redundancy, integrated virtualization, and on board storage and networking. That's why our margins are higher than the industry's
  • ...7 more annotations...
  • we now build our entire line of storage systems from general purpose server parts, including Solaris and ZFS, our open source file system.

      So, can anyone build a Sun storage device, or are Sun's "general purpose server parts" better (with better management and redundancy ...) ?
  • using a general purpose OS allows us to easily embrace specialized components (from flash memory to GPU's)
  • why am I paying you a million dollars?" I responded, "You can absolutely run it for free. You just can't call me on Christmas day, you'll be on your own." He gave me the PO.

      Schwartz gives the strong impression of an IT company _without_ its hand in your pocket. It is a similar attitude and reputation, though with proprietary software, rather than services (for free software), that seems to have made Microsoft so wealthy in the late eighties and nineties.
  • Solaris OEM agreements with IBM, Dell, Intel, Fujitsu and HP are so important to our end customers - they know they'll never be locked in.
  • These open source platforms generate, alongside the services attached to them, over a billion dollars a year, making Sun by far and away the world's largest open source software company.

      Hundreds of millions of dollars a year from open source Java alone!
  • Fighting free and open software, like fighting free news or free search, is like fighting gravity - and btw, gravity gets a lot stronger during economic downturns.

  • There is a robust, well-designed open source PBX Server called SipX that is primarily backed by Nortel (due to their acquisition of the creators, Pingtel).

  • The industry stewards have countered Apple's move with their own application stores, so there's a huge opportunity to write the "killer app" for one of several smartphone platforms.
  • 40 MB to less than 4 MB of free RAM
  • one-app-at-a-time requirement complicates any implementation of a copy-and-paste mechanism.
  • ...45 more annotations...
  • As a security sandbox, the iPhone OS permits only one third-party application to run at a time, and not in the background.
  • adding some useful Bluetooth profiles that supported stereo headsets, data synchronization, or the ability to implement multiplayer games would be usefu
  • iPhone OS 3, that provides some of the missing features mentioned here, such as the A2DP profile for Bluetooth, voice recording, and copy-and-paste.
  • Have to learn Objective-C; is only smartphone platform that uses it.
  • Competitors will soon catch up on the UI.
  • embed navigation and GPS plotting into applications.
  • provide their own map content
  • The OS now supports the use of accessories connected to the iPhone either through its 30-pin docking connector or wirelessly via Bluetooth. Now that the device has been "opened", you can expect an entire ecosystem to build up around the device, much like the iPod has.
  • peer-to-peer connectivity using Bonjour
  • developers can now allow users, from within the application, to purchase and obtain new content
  • No voice dial.
  • A client-server mechanism provides access to low-level system resources, and in fact the kernel itself is a server that parcels out resources to those applications that need them. This transaction scheme allows applications to exchange data without requiring direct access to the OS space.
  • C/C++ for porting existing UNIX applications, and Java to port Java ME MIDlets. As mentioned previously, the software stack offers several run-times that offer application development using WRT widgets, Flash, and Python. The primary programming language for the platform is Symbian C++,
  • Handango has managed the wide-scale distribution of Nokia applications. In February, Nokia announced plans to launch its Ovi Store, which sells applications, videos, games, pod-casts and other content, similar to Apple's App Store. The store will be accessible by Nokia S60 smartphones in May.
  • Non-standard Symbian C++ has steep learning curve, with special idioms to master. Large number of Symbian APIs to learn, since it contains hundreds of classes and thousands of member functions.
  • BlackBerry Device Software executes multiple applications simultaneously
  • Manages multiple e-mail Exchange e-mail accounts, along with support for POP3 and SMTP, and e-mails can have file attachments
  • FIPS 140-2 compliant, and supports AES or Triple DES encryption sessions via BlackBerry Enterprise Servers
  • BlackBerry Device Software has enhanced the capabilities of the platform with its own Java virtual machine (JVM), along with new Java classes that offer multitasking capabilities and UI enhancements to go beyond the capabilities of Java ME.
  • You can also take existing Java ME code and add specific BlackBerry classes to make a hybrid Java ME application
  • don't intermix MIDP 2.0 and BlackBerry API calls that perform either screen drawing or application management.
  • The catch to writing an application that uses BlackBerry API extensions is that it ties the application this smartphone. However, this is no worse than using the unique Java classes found in Google's Android.
  • Apple promotes the design goal that applications should accomplish one purpose.
  • no Flash support, and you can't download files.
  • For non-Exchange users, Apple's MobileMe online service, after some fits and starts in 2008, now supports the push of e-mails and changes to the calendar and contacts.
  • The iPhone 3G can work in tandem with Microsoft Exhange Server 2003 and 2007 to support enterprise operations.
  • Cocoa Touch is a subset of Apple's Cocoa,
  • Cocoa Touch components manage most of the writing to the screen and playing media, yet there are APIs exposed that let you access the accelerometer and camera.
  • Quartz engine is identical to the one found in Mac OS X
  • Only a select few higher-level frameworks have access to the kernel and drivers. If necessary, an application can indirectly access some of these services through C-based interfaces provided in a LibSystem library.
  • the SDK provides Dashcode, which is a framework based on a Web page composed of HTML and Javascript. You can use DashCode's simulator to write and test your web application. You can also use several other third-party frameworks to write web applications, and debug these with Aptanna Studio's tools.
  • Made by HTC, the G1 is the first smartphone using the Android platform.
  • e-mail program (which makes use of Google's Gmail), a mapping program (using the company's Google Maps), and a browser that uses WebKit, not Google's Chrome web browser
  • Android is not Java ME, nor does it support such applications
  • ability to both browse and manage multiple IM conversations. On the other hand, such heavy use of the smartphone's CPU shortens battery life significantly. Maybe Apple is on to something in limiting the number of applications that the platform can run.
  • On the positive side, the Android APIs support a touch interface (and the G1 has a capacitive touch screen), but not any multi-touch gestures.
  • copying text from the web pages is the browser isn't allowed
  • The advantage to Android's use of a different bytecode interpreter is that the DVM was designed so that multiple instances of it can run, each in their own protected memory space, and each executing an application. While this approach offers stability and a robust environment for running multiple applications, it does so at the expense of compatibility with Java ME applications.
  • Seasoned Java programmers will find the Android SDK an amalgam of Java SE and Java ME methods and classes, along with unique new ones
  • compile the Java code to generate Dalvik bytecode files, with an extension of .dex. These files, along with the manifest, graphics files, and XML files, are packaged into an .apk file that is similar to a Java JAR file.
  • The certificate that you use to generate the private key does not require a signing authority, and you can use self-signed certificates for this purpose.
  • The Developer Phone provides access to a shipping Android device without the cash outlay or contract contortions required when developing for the other platforms.
  • in February the site began supporting priced applications. Google allows developers to take seventy percent of the proceeds.
  • it's possible that you might pick up a malicious application before it is detected by the user community.
  • Open source, open platform: if you hate the mail program, some third-party is writing a better one.

    Lengthy developer's overview of Symbian, Mac OS X iPhone, Blackberry, Android. This talks about the leading app platforms except Java ME and Windows Mobile, though it does explain how Blackberry and Symbian support Java ME.

Design Patterns: 15 Years After the Revolution, by Danny Kalev @ InformIT [2009-10-30] - 1 views

  • by defining a description template that included among the rest: Known uses. Sample code (as opposed to a typical algorithm which were often described in plain English and perhaps a few sketchy lines of pseudo-code). Collaboration (A description of how classes and objects used in the pattern interact with each other). Consequences (results and side-effects). Related patterns.
  • Would a 2009 catalog of the 23 classic design patterns look much different? According to the authors of Design Patterns: Elements of Reusable Code, the answer is no.
  • The authors would reclassify certain patterns and omit a few of the original patterns but the design and implementation would remain pretty much the same: "We have found that the object-oriented design principles and most of the patterns haven't changed since then" says Erich Gamma. You can't escape the feeling that patterns are frozen in time
  • ...2 more annotations...
  • In the meantime, in the C++ world the tide has turned towards a completely different paradigm known as generic programming (and to some extent, functional programming). Instead of plain classes and a complex inheritance chain, C++ these days uses templates, meta-programming and static type checking. The C++ Standard Library is the most prominent showpiece of the generic and functional programming idioms.
  • Over-engineering is another source of criticism. Programmers who become acquainted with patterns are often tempted to solve every problem using a pattern, even when a much simpler solution would probably be a better choice.
