PyPyのインタプリタを実装する目的で策定されました。 面白いのは処理系実装の方で、RPythonのプログラムをC(など)に変換するコンパイラになってます。 この説明だとPythonをコンパイルする夢の処理系かと早合点する人が多いですが、Cに変換できる程に制限したサブセットなので実際はPython風に書ける小さな言語処理系記述DSL程度です。 RubyのJIT処理系を目指して作られたTopazもこのRPythonで書かれていたので色々勘違いされて「Rubyはあまりに遅くて、RubyインタプリタをPythonで書き直したら5倍速くなった」なんて冗談じみた話も出回ってましたが完全に誤解です。

Install Virtualbox Without Admin Privileges On Pc
Tumblr media
Let’s consider an easier way to force any program to run without administrator privileges (without entering the admin password) and with UAC enabled (Level 4, 3 or 2 of the UAC slider). Let’s take the Registry Editor as an example — regedit.exe (it is located in the C: Windows folder). Notice the UAC shield next to the app icon.
Installing VirtualBox Without Administrator Rights. Google Chrome installs without admin privileges, but it's only available for the user. STEP 2 Press “F8” three times at the first screen after the computer begins rebooting. Then select “Safe Mode” from the “Boot Options” menu that appears. STEP 3 Select the.

Portable software as a general rule is written in poor languages. AutoHotkey, AutoIt and NSIS are the three main languages in use, because they allow people to moderately easily produce not enormous binaries and have a surprisingly low initial learning curve (though later on you hit plenty of walls with them; none of them is suited as a general purpose programming language).

I speak this as the developer of the PortableApps.com Launcher, which I did in NSIS as the launchers already in use were NSIS, and as size matters a lot (that killed things like Python outright, though using the RPython parts of PyPy with the garbage collector ripped out would have worked---I checked it out and was able to successfully compile <100KB executables; D was disqualified for some reason I do not recall, Go for its heavy runtime even after ripping out the Unicode tables, &c.), and as I was not at all comfortable in C or C++ at the time.

I rather suspect that a large part of the reason for the apparently poor language choice is that the people that develop and use such things are strongly predominantly young people who are having to rove from computer to computer; as they get older, they tend to end up with a machine of their own and so no longer need portable apps. I don't any more, for example (and I don't use Windows any more either). The developers of these things are in consequence similarly young and have not yet learned good sense in programming (I include myself in that category, though I reckon the PortableApps.com Launcher to contain best-of-class engineer in the portable software space---five years later, at age 22, I am surprisingly unashamed of it, though now I would write it in Rust; I should try that one of these years).

Introduction to Python Programming: Beginners’ Guide to Choosing the Best Language
Have you ever wondered why most programmers are using Python instead of other programming languages? Let this introduction to Python Programming enlighten you and enable you to understand the importance of using the right language to ace in your chosen field.
How Python Came About
During the late 1980s, a programming language was created. It was named after Monty Python, but its impact on today’s IT sector is by no means a joke. This language has a range of applications — from microchip testing to building video games. Python was considered as a scripting language due to the historical blur between general purpose programming languages and scripting languages.
The idea of creating a unique programming language came about when Guido van Rossum had to deal with the shortcomings of the ABC language. Rossum began developing a language that is capable of integrating all the good features of the ABC language with added features like exception handling and extensibility.
In 1994, Python 1.0 was released. This language borrowed its system from the Modula-3 and it had the capacity to interact with the Amoeba operating system. Python 1.0 was also packed with various functional programming tools. When Python’s core development team had to move to Beopen.com in the year 2000, many improvements have already been added, thus, the birth of Python 2.0. The new language included support for Unicode and the Garbage Collector.
By the end of 2008, Python 3.0 has been released. This upgrade finally eradicated the idea of backward compatibility. This language possessed the latest design to prevent duplicative modules and constructs. However, it remained to be a multiple paradigm language which offers developer options for structured programming, functional programming, and object orientation.
In February 2015, the Python 3.4.3 version was released. This program offers rapid improvement in Unicode support. New features were also added to Python 3.5 which was released in September 2015.
Python Today
Today, Python offers multiple implementations which include Jython, a script in Java for the Java Virtual Machine; the Pypy version which was translated into C and written in RPython; and the IronPython which was written in C# purposely for a Common Language Infrastructure. CPython which was developed by the Python Software Foundation and written in C is considered as the most popular and default implementation of the language.
Python implementations work well in the native language with which they were written, and at the same time, capable of being used together with other languages through the use of various modules. Most of the modules used on community development models are free and open-source.
Python is an object-oriented, interpreted, and high-level programming language that’s packed with dynamic semantics. Python programming has built-in data structures and packed with dynamic binding and typing. This made the language extremely useful for rapid application development. It’s also used as a glue or scripting language to join existing components together.
Python is relatively easy for beginners to get into because it’s simple to use and easy to learn. Using Python can easily reduce the costs of program maintenance. Another important thing is that python is supporting various packages and modules which encourage code reuse and program modularity. You can conveniently utilize the Python interpreter as well as the extensive library which were made available in binary or source form without any charge for major platforms. These tools are also freely distributed.
Many programmers love Python due to the increased productivity that it can provide. There’s no compilation step. The test, edit, and debug cycle is amazingly fast. Debugging the Python program is also easy. Bad or bug inputs won’t generate a segmentation fault. When the Interpreter finds errors, an exception will be raised. The moment the program does not catch an exception, a stack trace will be printed.
The source level debugger permits the inspection of global and local variables, sets breakpoints, evaluates an arbitrary expression and steps through codes one line at a time. Even the Debugger was written in Python, testifying to the program’s introspective power. In most cases, the easiest way to fix a program is simply to incorporate several print statements to a source. The test, edit, and debug cycle is making this simple approach extremely effective.
Python has a design philosophy that emphasized code readability. It also used whitespace indentations to delimit the code block rather than keywords or curly braces. The program includes a syntax that permits a programmer to conveniently express various concepts in fewer code lines unlike when using other languages such as Java or C++.
Benefits of Using Python

Even a novice developer can easily handle Python. The code can be read and a lot of things can be done by simply looking at the language. In addition, the user can even execute lots of complex functionalities due to the existence of the standard library functionality.
Python supports multiple platforms and systems.
This programming language is object-oriented.
Python has extended its reach to exceptional heights with the introduction of a card-sized micro-computer known as Raspberry Pi. Users can conveniently build radios, games, and cameras with ease. If you learn Python, it would open a new avenue for you to generate extraordinary applications and even gadgets.
With a plethora of frameworks which made web programming flexible, Python is the best deal for every programmer. Django is a well-known Python framework that’s used for web development.
Using Python gives rise to fast development through the application of fewer codes. Small teams can effectively handle Python.
Using Python would allow you to scale many complex applications with ease.
Many resources are made available for those who are using Python.
This programming language provides a built-in testing structure to set timely debugging as well as enable fastest workflows.
Even IT giants such as Google, Yahoo, NASA, IBM, Disney, and Nokia prefer Python over other programming languages.

Python – A Diverse Programing Language
Python has such diverse application, which resulted from the combination of various features that gave this particular language the edge over others. Here’s why you should take advantages of this diversity:
Extensive support libraries
A large standard library is provided for users and this includes areas such as string operations, internet protocols, operation system interfaces and web service tools. Numerous high use programming tasks were already incorporated into the standard library. This greatly reduced the length of the code that’s supposed to be written.
Presence of 3rd party modules
The PyPI or Python Package Index is packed with numerous 3rd party modules which made Python capable of working with other platforms and languages.
Ease of learning and availability of support
Another important thing that most programmers appreciate about Python is its uncluttered syntax and excellent readability. This helps a beginner effectively utilize the language. In addition, the PEP 8 code style guideline provides rules to facilitate formatting of codes. A long list of active developers and users serves as an internet resource bank that encourages development and incessant adoption of the Python language.
Open Source/Community Development
This language was developed under an open source license. It’s also OSI-approved. This would mean that Python can be used and distributed freely, even for commercial purposes. The development of this programming language came about because of the need of the community. This is why mailing lists and hosting conferences are also provided.
User-friendly data structures
With a built-in list as well as dictionary data structures that can be utilized to form a fast runtime data structure, Python is definitely the best choice. The language also provides an option of high level and dynamic data typing that reduced the length of needed support code.
Speed and productivity
Programmers enjoy using Python’s clean and object-oriented design, enhanced process control capability, and strong text processing and integration features. Python is also packed with its very own unit testing framework that contributes to the increase in productivity and speed. For many users, Python remains to be a viable alternative when it comes to building complex and multiple protocol network applications.
Python’s dynamic and object-oriented features can be compared with that of .NET-based languages and Java. It’s a general purpose substrate which is compatible with various types of software development. Python offers strong support that can be used for higher programmer productivity in all phases of the development life cycle. If you want a programming language that is well-suited for complex and large projects with changing requirements, then Python is the best choice.
According to InfoWorld, Python is considered as one of the most rapidly growing programming language with a user base that was doubled in 2004. Almost 14% of the total number of programmers is into using Python. This programming language plays a key role in mission critical applications in stock exchanges, cell phones, high-end newspaper websites, ship building, movie animation and even air traffic control.
All things considered, there are very good reasons why Python has remained one of the more ubiquitous programming languages today.

Hy: The joke just got pretty serious
(btw, the source is on github)
During the sprints at PyCon in a spare moment after some awesome OpenGov hacking, I ended up doing the unthinkable:
rpython support in Hy.
Yes. That’s right. Lisp —> Python —> C —> x86 instructions.
The thanks here goes to Romain Guillebert - who is a really funny rpythonista and took the time to sit down and help me with this frankly insane idea.
It works, though. I filed a bug on shipping rpython bits from PyPy’s Debian package (hi, tumbleweed!), which should make building this a skitch easier.
Finally, and unrelatedly, I also just got a .hy —> .pyc compiler working (huzzah!) which means no one will ever know we wrote anything in Lisp, ever.
As always, play with the REPL, star the code or have a laugh with it.
Let me know what you hack up!
I’ll post the lightning talk I gave after it’s posted :)

Hello world!
I have set up this page to have a place to do some blogging. I intend to write some blogs to get some publicity for the [Haskell-Python](http://bitbucket.org/cfbolz/haskell-python) project. Haskell-Python is an attempt to implement Haskell with RPython, to see if purely functional and lazy languages, e.g. Haskell, can benefit from just-in-time compilation. This site is created with [Syte](http://rigoneri.github.com/syte/), but I have added everything except the GitHub page. These can be found as the following branches on [my Syte fork](https://github.com/eventh/syte): * Projects page: [ohloh-integration](http://github.com/eventh/syte/tree/ohloh-integration) * Bitbucket page: [bitbucket](http://github.com/eventh/syte/tree/bitbucket) (merged upstream) * Documents page: [documents](http://github.com/eventh/syte/tree/documents) * About page: [about-page](http://github.com/eventh/syte/tree/about-page) I have modified Syte to enable memcache and serve static content from Amazon S3. In the near future I might write a blog post explaining how you can do so yourself. Any other changes I have made to Syte can be found in the [eventh branch](http://github.com/eventh/syte/tree/eventh).

adventures in hy, part III
Over the last few days, I've made some incremental improvements to Hy, but I've been mostly preparing it for a small talk later on this next week. I am, however, already considering a bit of a rewrite -- there is a lot of code sitting in the Hy tree that was intended to use the old "modfaker" method of Python module generation (which sucked) I'm most interested (I think) in bootstrapping Hy in Hy (no small task) and getting macros in early (really really needed), so, dear lazyweb: Has anyone split rpython out of PyPy yet? Are there any sort of docs on this? The idea of rHy is pretty intriguing, I'd like to make it happen. More to come soon (including the slides!)
