  • Why do "Joke" programming languages exist? [closed]

    - by ThePlan
    First of all please be aware this post contains some abusive language but I hope it will not bother anyone. I apologize for the bad language but that's what the name is. As I've been doing documentation on existing programming languages attempting to make a complete list of them I stumbled across terrible programming languages, which were clearly not made for actual use and implementation due to their insane difficulty. Languages such as Brainfu*k and LOLCODE or Whitespace are fool languages because they have no real use. For example, a "Hello world" program written in BrainFu*k. Taken from Wikipedia: The following program prints "Hello World!" and a newline to the screen: +++++ +++++ initialize counter (cell #0) to 10 [ use loop to set the next four cells to 70/100/30/10 > +++++ ++ add 7 to cell #1 > +++++ +++++ add 10 to cell #2 > +++ add 3 to cell #3 > + add 1 to cell #4 <<<< - decrement counter (cell #0) ] > ++ . print 'H' > + . print 'e' +++++ ++ . print 'l' . print 'l' +++ . print 'o' > ++ . print ' ' << +++++ +++++ +++++ . print 'W' > . print 'o' +++ . print 'r' ----- - . print 'l' ----- --- . print 'd' > + . print '!' > . print '\n' or another example taken from LOLCODE language: HAI CAN HAS STDIO? PLZ OPEN FILE "LOLCATS.TXT"? AWSUM THX VISIBLE FILE O NOES INVISIBLE "ERROR!" KTHXBYE These languages are very difficult to learn/read/work with. My question is - Why do they exist? What is the purpose of them? Also, is there an official "name" for these type of languages?

  • Software development stack 2012

    A couple of months ago, I posted on Google+ about my evaluation period for a new software development stack in general. "Analysing existing 'jungle' of multiple applications and tools in various languages for clarification and future design decisions. Great fun and lots of headaches... #DevelopersLife" Surprisingly, there was response... ;-) - And this series of articles is initiated by this post. Thanks Olaf. The past few years... Well, after all my first choice of software development in the past was Microsoft Visual FoxPro 6.0 - 9.0 in combination with Microsoft SQL Server 2000 - 2008 and Crystal Reports 9.x - XI. Honestly, it is my main working environment due to exisiting maintenance and support plans with my customers, but also for new project requests. And... hands on, it is still my first choice for data manipulation and migration options. But the earth is spinning, and as a software craftsman one has to be flexible with the choice of tools. In parallel to my knowledge and expertise in the above mentioned tools, I already started very early to get my hands dirty with the Microsoft .NET Framework. If I remember correctly, I started back in 2002/2003 with the first version ever. But this was more out of curiousity. During the years this kind of development got more serious and demanding, and I focused myself on interop and integrational libraries and applications. Mainly, to expose exisitng features of the .NET Framework to Visual FoxPro - I even had a session about that at the German Developer's Conference in Frankfurt. Observation of recent developments With the recent hype on Javascript and HTML5, especially for Windows 8 and Windows Phone 8 development, I had several 'Deja vu' events... Back in early 2006 (roughly) I had a conversation on the future of Web and Desktop development with my former colleagues Golo Roden and Thomas Wilting about the underestimation of Javascript and its root as a prototype-based, dynamic, full-featured programming language. During this talk with them I took the Mozilla applications, namely Firefox and Thunderbird, as a reference which are mainly based on XML, CSS, Javascript and images - besides the core rendering engine. And that it is very simple to write your own extensions for the Gecko rendering engine. Looking at the Windows Vista Sidebar widgets, just underlines this kind of usage. So, yes the 'Modern UI' of Windows 8 based on HTML5, CSS3 and Javascript didn't come as any surprise to me. Just allow me to ask why did it take so long for Microsoft to come up with this step? A new set of tools Ok, coming from web development in HTML 4, CSS and Javascript prior to Visual FoxPro, I am partly going back to that combination of technologies. What is the other part of the software development stack here at IOS Indian Ocean Software Ltd? Frankly, it is easy and straight forward to describe: Microsoft Visual FoxPro 9.0 SP 2 - still going strong! Visual Studio 2012 (C# on latest .NET Framework) MonoDevelop Telerik DevCraft Suite WPF ASP.NET MVC Windows 8 Kendo UI OpenAccess ORM Reporting JustCode CODE Framework by EPS Software MonoTouch and Mono for Android Subversion and additional tools for the daily routine: Notepad++, JustCode, SQL Compare, DiffMerge, VMware, etc. Following the principles of Clean Code Developer and the Agile Manifesto Actually, nothing special about this combination but rather a solid fundament to work with and create line of business applications for customers.Honestly, I am really interested in your choice of 'weapons' for software development, and hopefully there might be some nice conversations in the comment section. Over the next coming days/weeks I'm going to describe a little bit more in detail about the reasons for my decision. Articles will be added bit by bit here as reference, too. Please bear with me... Regards, JoKi

  • My treeview Data is Not changing.

    - by Vibin Jith
    Hai , I am trying to display the user permission in a treeview.For each user permissions are stored in the database as xml file. In the page, a Combo box used to list the users and a treeView used to bind the Permission xml. When the user get selected in the combo box , i took the xml from the database and connect with xmlDatasource and bind with the treeView. What happening is , First time the TreeView fill with the xml nodes and another time it will not work. For the first selection it's ok. Anothers selections are not effected by the treeview. The code is debugging. No problem. Can you just tell ,why the treeview datasource is not updating. I used this code .. Dim permissionRoot = From permissionNode In MyUser.UserPermissionXml.Root.Elements("menuNode") XmlTreeViewSource.Data = permissionRoot(0).ToString trvPermission.DataSource = XmlTreeViewSource trvPermission.DataBind() SetPermission(trvPermission.Nodes(0)) The markups <asp:TreeView ID="trvPermission" runat="server" ExpandDepth="2" ShowCheckBoxes="All" ShowLines="True" ForeColor="#005782" > <DataBindings> <asp:TreeNodeBinding DataMember="menuNode" TextField="title" ValueField="value" /> </DataBindings> </asp:TreeView>

  • My Codemash 2011 Retrospective

    - by Greg Malcolm
    I just got back from Codemash yesterday, and still on an adrenaline buzz. Here's my take on this years encounter: The Awesome Nearly everybody in one place Codemash is the ultimate place to catch up with community friends. This is my 3rd year visiting and I've got to know a great number of very cool people through various conferences, Give Camps and other community events. I'm finding more and more that Codemash is the best place to catch up with everybody regardless of technology interest or location. Of course I always make a whole bunch more friends while I'm there! Yay! Open Spaced I found the open spaces didn't work so well last year. This year things went a lot smoother and the topics were engaging and fresh. While I miss Alan Steven's approach of running it like an agile project, it was very cool to see that it evolving. Laptops were often cracked open, not just once but frequently! For example: Jasmine - Paired on a javascript kata using the Jasmine javascript test runner J - Sat in on a J demo from local J enthusiast, Tracy Harms Watir - More pairing, this time using Ruby with the watir-webdriver through cucumber. I'd mostly forgotten that Cucumber runs just fine without Rails. It made a change to do without. The other spaces were engaging too, but I think that's enough for that topic. Javascript Shenanigans I've already mentioned that I attended a Jasmine kata session. Jasmine is close to my heart right now every since I discovered it while on the hunt for a decent Javascript testing framework for a javascript koans project earlier this year. Well, it also got covered in the Java Precompiler and Pillar's vendor session, which was great to see. Node.js was also a reoccurring theme. Node.js in a nutshell? It's an extremely scalable Event based I/O server which runs on Javascript. I'd already encountered through a Startup Weekend project and have been noticing increasing interest of late. After encountering more node.js driven excitement from my peers at codemash I absolutely had to attend the open space on it. At least 20 people turned up and by the end we had some answers, a whole ton of new questions and an impromptu user group in the form of a twitter channel (#nodemash). I have no idea where this is going to go or how big it is going to become, but if it can cross the chasm into the enterprise it could become huge... Scala Koans I'm a bit of a Koans addict, and I really need more exposure to functional languages so I gave the Scala Koans precompiler a try. Great fun! I'm really glad I attended because I found I had a whole ton of questions. Currently the koans are available here, and the answers are here. Opportunities While we're on the subject can we change the subject now? Hai Gregory, You really need to keep the drinking for later in the day. I mean seriously, you're 34 and you still do this every single time! Sure, you made it to Chad Fowler keynote ok, but you looking a rather pale weren't you? Also might have been nice to attend 'Netflicks in the Cloud' instead of 'Sleeping It Off For People Who Should Know Better'. Kthxbye PS: Stop talking to yourself Not that I entirely regret it, I've had some of my greatest insights through late night drunken conversations at the CodeMash bar. Just might be nice to reign it in a little and get something out of the next morning too. Diversity This is something that is in the back of my mind because of conversations at Codemash as well as throughout the year; I'm realizing more and more how discouraging the IT profession is for women. I notice in the community there has been a lot of attention paid to stamping out harrasment, which is good, but there also seems to be a massive PR issue. I really don't have any solutions, but I figure it can't hurt to pay more attention to whats going on... And in Other News I now have a picture of Chad Fowler giving me more cowbell! Sadly I managed to lose the cowbell later on. Hopefully it's gone to a Better Place. The Womack Family Band joined in with the musicians jam this year. There's my cowbell again! Why must you hide from me? I also finally went in the water for the first time in all the I've been coming to codemash. Why did I wait so long?!?

  • Problem in understanding connectSlotsByName() in pyqt???

    - by Jebagnanadas
    Hi all, I couldn't understand the connectSlotsByName() method which is predominently used by pyuic4.. As far the class is single in a PyQt file it's ok since we can use self which will be associated with a single object throughout.. But when we try to use various classes from different files the problem and the need to use connectSlotsByName() arises.. Here's what i encountered which is weird.. I created a stacked widget.. I placed my first widget on it.. It has a button called "Next ". On clicking next it hides the current widget and adds another widget which has the "click me" button.. The problem here is the click event for "click me" button in second is not captured.. It's a minimal example that i can give for my original problem.. Please help me.. This is file No.1..(which has the parent stacked widget and it's first page). On clicking next it adds the second page which has "clickme" button in file2.. from PyQt4 import QtCore, QtGui import file2 class Ui_StackedWidget(QtGui.QStackedWidget): def __init__(self,parent=None): QtGui.QStackedWidget.__init__(self,parent) self.setObjectName("self") self.resize(484, 370) self.setWindowTitle(QtGui.QApplication.translate("self", "stacked widget", None, QtGui.QApplication.UnicodeUTF8)) self.createWidget1() def createWidget1(self): self.page=QtGui.QWidget() self.page.setObjectName("widget1") self.pushButton=QtGui.QPushButton(self.page) self.pushButton.setGeometry(QtCore.QRect(150, 230, 91, 31)) self.pushButton.setText(QtGui.QApplication.translate("self", "Next >", None, QtGui.QApplication.UnicodeUTF8)) self.addWidget(self.page) QtCore.QMetaObject.connectSlotsByName(self.page) QtCore.QObject.connect(self.pushButton,QtCore.SIGNAL('clicked()'),self.showWidget2) def showWidget2(self): self.page.hide() obj=file2.widget2() obj.createWidget2(self) if __name__ == "__main__": import sys app = QtGui.QApplication(sys.argv) ui = Ui_StackedWidget() ui.show() sys.exit(app.exec_()) Here's file2 from PyQt4 import QtGui,QtCore class widget2(): def createWidget2(self,parent): self.page = QtGui.QWidget() self.page.setObjectName("page") self.parent=parent self.groupBox = QtGui.QGroupBox(self.page) self.groupBox.setGeometry(QtCore.QRect(30, 20, 421, 311)) self.groupBox.setObjectName("groupBox") self.groupBox.setTitle(QtGui.QApplication.translate("self", "TestGroupBox", None, QtGui.QApplication.UnicodeUTF8)) self.pushButton = QtGui.QPushButton(self.groupBox) self.pushButton.setGeometry(QtCore.QRect(150, 120, 92, 28)) self.pushButton.setObjectName("pushButton") self.pushButton.setText(QtGui.QApplication.translate("self", "Click Me", None, QtGui.QApplication.UnicodeUTF8)) self.parent.addWidget(self.page) self.parent.setCurrentWidget(self.page) QtCore.QMetaObject.connectSlotsByName(self.page) QtCore.QObject.connect(self.pushButton,QtCore.SIGNAL('clicked()'),self.printMessage) def printMessage(self): print("Hai") Though in both the widgets(i mean pages) QtCore.QMetaObject.connectSlotsByName(self.page) the clicked signal in second dialog isn't getting processed.

  • Base de Datos Oracle, su mejor opción para reducir costos de IT

    - by Ivan Hassig
    Por Victoria Cadavid Sr. Sales Cosultant Oracle Direct Uno de los principales desafíos en la administración de centros de datos es la reducción de costos de operación. A medida que las compañías crecen y los proveedores de tecnología ofrecen soluciones cada vez más robustas, conservar el equilibrio entre desempeño, soporte al negocio y gestión del Costo Total de Propiedad es un desafío cada vez mayor para los Gerentes de Tecnología y para los Administradores de Centros de Datos. Las estrategias más comunes para conseguir reducción en los costos de administración de Centros de Datos y en la gestión de Tecnología de una organización en general, se enfocan en la mejora del desempeño de las aplicaciones, reducción del costo de administración y adquisición de hardware, reducción de los costos de almacenamiento, aumento de la productividad en la administración de las Bases de Datos y mejora en la atención de requerimientos y prestación de servicios de mesa de ayuda, sin embargo, las estrategias de reducción de costos deben contemplar también la reducción de costos asociados a pérdida y robo de información, cumplimiento regulatorio, generación de valor y continuidad del negocio, que comúnmente se conciben como iniciativas aisladas que no siempre se adelantan con el ánimo de apoyar la reducción de costos. Una iniciativa integral de reducción de costos de TI, debe contemplar cada uno de los factores que  generan costo y pueden ser optimizados. En este artículo queremos abordar la reducción de costos de tecnología a partir de la adopción del que según los expertos es el motor de Base de Datos # del mercado.Durante años, la base de datos Oracle ha sido reconocida por su velocidad, confiabilidad, seguridad y capacidad para soportar cargas de datos tanto de aplicaciones altamente transaccionales, como de Bodegas de datos e incluso análisis de Big Data , ofreciendo alto desempeño y facilidades de administración, sin embrago, cuando pensamos en proyectos de reducción de costos de IT, además de la capacidad para soportar aplicaciones (incluso aplicaciones altamente transaccionales) con alto desempeño, pensamos en procesos de automatización, optimización de recursos, consolidación, virtualización e incluso alternativas más cómodas de licenciamiento. La Base de Datos Oracle está diseñada para proveer todas las capacidades que un área de tecnología necesita para reducir costos, adaptándose a los diferentes escenarios de negocio y a las capacidades y características de cada organización.Es así, como además del motor de Base de Datos, Oracle ofrece una serie de soluciones para optimizar la administración de la información a través de mecanismos de optimización del uso del storage, continuidad del Negocio, consolidación de infraestructura, seguridad y administración automática, que propenden por un mejor uso de los recursos de tecnología, ofrecen opciones avanzadas de configuración y direccionan la reducción de los tiempos de las tareas operativas más comunes. Una de las opciones de la base de datos que se pueden provechar para reducir costos de hardware es Oracle Real Application Clusters. Esta solución de clustering permite que varios servidores (incluso servidores de bajo costo) trabajen en conjunto para soportar Grids o Nubes Privadas de Bases de Datos, proporcionando los beneficios de la consolidación de infraestructura, los esquemas de alta disponibilidad, rápido desempeño y escalabilidad por demanda, haciendo que el aprovisionamiento, el mantenimiento de las bases de datos y la adición de nuevos nodos se lleve e cabo de una forma más rápida y con menos riesgo, además de apalancar las inversiones en servidores de menor costo. Otra de las soluciones que promueven la reducción de costos de Tecnología es Oracle In-Memory Database Cache que permite almacenar y procesar datos en la memoria de las aplicaciones, permitiendo el máximo aprovechamiento de los recursos de procesamiento de la capa media, lo que cobra mucho valor en escenarios de alta transaccionalidad. De este modo se saca el mayor provecho de los recursos de procesamiento evitando crecimiento innecesario en recursos de hardware. Otra de las formas de evitar inversiones innecesarias en hardware, aprovechando los recursos existentes, incluso en escenarios de alto crecimiento de los volúmenes de información es la compresión de los datos. Oracle Advanced Compression permite comprimir hasta 4 veces los diferentes tipos de datos, mejorando la capacidad de almacenamiento, sin comprometer el desempeño de las aplicaciones. Desde el lado del almacenamiento también se pueden conseguir reducciones importantes de los costos de IT. En este escenario, la tecnología propia de la base de Datos Oracle ofrece capacidades de Administración Automática del Almacenamiento que no solo permiten una distribución óptima de los datos en los discos físicos para garantizar el máximo desempeño, sino que facilitan el aprovisionamiento y la remoción de discos defectuosos y ofrecen balanceo y mirroring, garantizando el uso máximo de cada uno de los dispositivos y la disponibilidad de los datos. Otra de las soluciones que facilitan la administración del almacenamiento es Oracle Partitioning, una opción de la Base de Datos que permite dividir grandes tablas en estructuras más pequeñas. Esta aproximación facilita la administración del ciclo de vida de la información y permite por ejemplo, separar los datos históricos (que generalmente se convierten en información de solo lectura y no tienen un alto volumen de consulta) y enviarlos a un almacenamiento de bajo costos, conservando la data activa en dispositivos de almacenamiento más ágiles. Adicionalmente, Oracle Partitioning facilita la administración de las bases de datos que tienen un gran volumen de registros y mejora el desempeño de la base de datos gracias a la posibilidad de optimizar las consultas haciendo uso únicamente de las particiones relevantes de una tabla o índice en el proceso de búsqueda. Otros factores adicionales, que pueden generar costos innecesarios a los departamentos de Tecnología son: La pérdida, corrupción o robo de datos y la falta de disponibilidad de las aplicaciones para dar soporte al negocio. Para evitar este tipo de situaciones que pueden acarrear multas y pérdida de negocios y de dinero, Oracle ofrece soluciones que permiten proteger y auditar la base de datos, recuperar la información en caso de corrupción o ejecución de acciones que comprometan la integridad de la información y soluciones que permitan garantizar que la información de las aplicaciones tenga una disponibilidad de 7x24. Ya hablamos de los beneficios de Oracle RAC, para facilitar los procesos de Consolidación y mejorar el desempeño de las aplicaciones, sin embrago esta solución, es sumamente útil en escenarios dónde las organizaciones de quieren garantizar una alta disponibilidad de la información, ante fallo de los servidores o en eventos de desconexión planeada para realizar labores de mantenimiento. Además de Oracle RAC, existen soluciones como Oracle Data Guard y Active Data Guard que permiten replicar de forma automática las bases de datos hacia un centro de datos de contingencia, permitiendo una recuperación inmediata ante eventos que deshabiliten por completo un centro de datos. Además de lo anterior, Active Data Guard, permite aprovechar la base de datos de contingencia para realizar labores de consulta, mejorando el desempeño de las aplicaciones. Desde el punto de vista de mejora en la seguridad, Oracle cuenta con soluciones como Advanced security que permite encriptar los datos y los canales a través de los cueles se comparte la información, Total Recall, que permite visualizar los cambios realizados a la base de datos en un momento determinado del tiempo, para evitar pérdida y corrupción de datos, Database Vault que permite restringir el acceso de los usuarios privilegiados a información confidencial, Audit Vault, que permite verificar quién hizo qué y cuándo dentro de las bases de datos de una organización y Oracle Data Masking que permite enmascarar los datos para garantizar la protección de la información sensible y el cumplimiento de las políticas y normas relacionadas con protección de información confidencial, por ejemplo, mientras las aplicaciones pasan del ambiente de desarrollo al ambiente de producción. Como mencionamos en un comienzo, las iniciativas de reducción de costos de tecnología deben apalancarse en estrategias que contemplen los diferentes factores que puedan generar sobre costos, los factores de riesgo que puedan acarrear costos no previsto, el aprovechamiento de los recursos actuales, para evitar inversiones innecesarias y los factores de optimización que permitan el máximo aprovechamiento de las inversiones actuales. Como vimos, todas estas iniciativas pueden ser abordadas haciendo uso de la tecnología de Oracle a nivel de Base de Datos, lo más importante es detectar los puntos críticos a nivel de riesgo, diagnosticar las proporción en que están siendo aprovechados los recursos actuales y definir las prioridades de la organización y del área de IT, para así dar inicio a todas aquellas iniciativas que de forma gradual, van a evitar sobrecostos e inversiones innecesarias, proporcionando un mayor apoyo al negocio y un impacto significativo en la productividad de la organización.

It isn't detected on ubuntu natty 64bit, 2.6.38-8-generic. fdisk -l cannot see it at all: Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x1bed746b Device Boot Start End Blocks Id System /dev/sda1 1 1689 13560832 27 Unknown /dev/sda2 * 1689 1702 102400 7 HPFS/NTFS /dev/sda3 1702 19978 146805760 7 HPFS/NTFS /dev/sda4 19978 60802 327914497 5 Extended /dev/sda5 25555 60802 283120640 7 HPFS/NTFS /dev/sda6 19978 23909 31571968 83 Linux /dev/sda7 23909 25555 13218816 82 Linux swap / Solaris Partition table entries are not in disk order lsusb can see it: Bus 003 Device 003: ID 059b:0070 Iomega Corp.

(2.6.38.4-pmagic), the drive was detected fine, I could mount it and got usb 3.0 speeds (at least they double the speeds I got from plugging same drive in usb 2 ports). dmesg in partedmagic did say something about no SuperSpeed endpoint which was an error I saw in a previous dmesg of ubuntu: Jun 27 15:49:02 (none) user.info kernel: [ 2.978743] xhci_hcd 0000:04:00.0: PCI INT A -> GSI 18 (level,

A number of unanswered threads with people with similar error messages and problems only. Hopefully someone here can help or point me in the right direction?!
