  • What is a good "free-form" ("type anywhere" or canvas-like) text editor? [on hold]

    - by scorpiodawg
    My 5-1/2 y.o. son is starting to use a computer and one of the things he likes to do is to type stuff into an editor. He has used TuxPaint before and is familiar with the idea of a "canvas" for painting stuff (where painting anything anywhere on the canvas is fair game). When he opened the text editor (this was gedit on Qimo Linux), he attempted to do the same thing -- he pointed the text cursor to an arbitrary location within the editor window and expected to be able to type there (like a "text canvas", if you will). I had to explain to him that he would have to press Enter a few times to create new lines, as well as press Space a few times to create columns before he could do that. This is sub-optimal. My question: are there any free-form, canvas-like text editors that I can have him use? Almost like hex editors of yore. I am not interested in getting him to create "text areas" in a paint program.

  • Is Learning C++ Through The Qt Framework Really Learning C++

    - by user866190
    The problem I have, is that most of the C++ books I read spend almost forever on syntax and the basics of the language, e.g. for and loops while, arrays, lists, pointers, etc. But they never seem to build anything that is simple enough to use for learning, yet practical enough to get you to understand the philosophy and power of the language. Then I stumbled upon QT which is an amazing library! But working through the demos they have, it seems like I am now in the reverse dilemma. I feel like the rich man's son driving round in a sports car subsidized by the father. Like I could build fantastic software, but have no clue what's going on under the hood. As an example of my dilemma take the task of building a simple web browser. In pure C++, I wouldn't even know where to start, yet with the Qt library it can be done within a few lines on code. I am not complaining about this. I am just wondering how to fill the knowledge void between the basic structure of the language and the high level interface that the Qt framework provides?

  • Microphone on a Dell Vostro 3360

    - by Pilb
    After upgrading my vostro 3360 on Ubuntu 12.04, I saw that drivers were not available for this version (notably for network). So I decided to install 11.10 but the mic still doesn't work (notably on Skype, Gtalk etc.) I join the model of the audio device and the drivers which were installed before I upgraded to ubuntu 12.04 (I succeeded only in installing the network one) Can you help me to find the solution to this problem with my microphone? Thanks , Pilb. Message in French : Bonjour, Après que je me sois rendu compte d'une anomalie dans la gestion du micro (sous Gtalk), j'ai essayé différentes solutions sans succès (1 2 et 3) Mon ordinateur dell vostro 3360 m'a été livré sous ubuntu 11.10, j'ai voulu le mettre sous 12.04 mais les drivers n'étaient pas compatibles. Je suis donc revenu sur Oneiric mais sans les drivers installés par Dell en usine. néanmoins, j'ai pris soin de noter leurs références (sans toutefois savoir si le micro fonctionne avec ces pilotes, mais cela me semble possible).

  • ¿Acaso el CFO necesita convertirse en un tecnólogo?

    - by RED League Heroes-Oracle
    La tecnología actual está afectando las funciones de toda la empresa. El CIO debe buscar nuevas maneras de ser un socio estratégico para el negocio y el CMO constantemente se enfrenta con decisiones acerca de la tecnología que hagan la función de marketing más eficiente a través de los datos. Incluso el papel CFO no es inmune. "El CFO en realidad no tiene que ser un tecnólogo, pero tienen que entender cómo el poder de la tecnología puede ayudarle a hacer su trabajo ", dice Nicole Anasenes, CFO de la empresa especialista en soluciones de software Infor. "Las presiones sobre el CFO no son tan diferentes de lo que siempre han sido, pero la interconexión del mundo y la tasa de cambio se suman a ellas" En el mundo empresarial actual, Anasenes dice , el CFO se preocupa por la reducción de costes, velocidad y flexibilidad - todo de una manera segura . La tecnología, en particular el cloud computing, es la clave para mejorar en esas tres áreas. Es importante tener en cuenta que el CIO y la línea de los líderes empresariales a menudo defienden diferentes puntos de vista. En general, el CIO tiende a ver el mundo a través de una lente de la contención de costos y seguridad y buscará almacenamiento de precios accequibles. El resto de los líderes empresariales , en cambio, se centran más en los proyectos de generación de ingresos en el espacio de análisis . En ese contexto , los directores financieros deben tratar de fortalecer las relaciones en toda la empresa y tomar ventaja de la tecnología Tomado de: http://www.cio.com/article/753147/Does_the_CFO_Need_to_Become_a_Technologist_?page=2&taxonomyId=3157

  • Social Engineering approach to collecting from deadbeat ebay winners

    - by Malcolm Anderson
    You just sold something on e-bay and now the winner won't pay up.  What do you do?  I'm not sure what the legality of this kind of Social Engineering hack is, but I believe you've got to give it points for elegance.   Here's the link to the lifehacker.com post (I can't find the original Reddit post.) Reddit user "BadgerMatt" (we'll call him Matt for short) recently posted a story about how he tried to sell tickets to a sporting event on eBay, but when the auction was won the winning bidder backed out of the deal. In some cases this is mainly an inconvenience and you can re-list the item, but Matt was selling tickets to a sporting event and no longer had the time to do that. With the losing bidders uninterested in the tickets, he was going to end up stuck with tickets he couldn't use and a deadbeat bidder who was unwilling to honor their contract. Rather than give up, Matt decided to trick her into paying: I created a new eBay account, "Payback" we'll call it, and sent her a message: "Hi there, I noticed you won an auction for 4 [sporting event] tickets. I meant to bid on these but couldn't get to a computer. I wanted to take my son and dad and would be willing to give you $1,000 for the tickets. I imagine that you've already made plans to attend, but I figured it was worth a shot." The woman agreed, but for $1,100. She paid for the auction, received the tickets, and then Matt (of course) never re-purchased them. Needless to say, the woman was angry. Perhaps it was the wrong thing for the right reasons, but I'm mostly jealous I never thought of it back when I still sold things on eBay.

  • Does a 77 Year Old Person Like To Use iPhone Siri? Of course!

    - by Gopinath
    When Apple releases any product, they just work irrespective of age, capability and ability of the users. It’s in the DNA of Steve Jobs and his colleagues at Apple to build products that just work with out any learning curve. The recent iPhone is loaded with Siri, an intelligent personal assistant. But can a 77 year old person quickly learn to use Siri for his day to day activities? Lets hear from a son who trained his 77 year old dad to use Siri on iPhone He caught on much faster than I thought he might. I was feeling proud of him and believed Siri would be a real productivity help in his life — seeing that, at 77, my dad still works full time as a realtor. I was encouraged that he really liked and would use his new personal assistant. Or at least I was until my mom called later that night. "Your father and I were just practicing with his new phone," Sigh. Well Siri will be great for my dad…if and when he remembers how to find her. Apple products are not for just techies like Android mobiles, they are for everyone. You can read the full story over here This article titled,Does a 77 Year Old Person Like To Use iPhone Siri? Of course!, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

  • Code Generation and IDE vs writing per Hand

    - by sytycs
    I have been programming for about a year now. Pretty soon I realized that I need a great Tool for writing code and learned Vim. I was happy with C and Ruby and never liked the idea of an IDE. Which was encouraged by a lot of reading about programming.[1] However I started with (my first) Java Project. In a CS Course we were using Visual Paradigm and encouraged to let the program generate our code from a class diagram. I did not like that Idea because: Our class diagram was buggy. Students more experienced in Java said they would write the code per hand. I had never written any Java before and would not understand a lot of the generated code. So I took a different approach and wrote all methods per Hand (getter and Setter included). My Team-members have written their parts (partly generated by VP) in an IDE and I was "forced" to use it too. I realized they had generated equal amounts of code in a shorter amount of time and did not spend a lot of time setting their CLASSPATH and writing scripts for compiling that son of a b***. Additionally we had to implement a GUI and I dont see how we could have done that in a sane matter in Vim. So here is my Problem: I fell in love with Vim and the Unix way. But it looks like for getting this job done (on time) the IDE/Code generation approach is superior. Do you have equal experiences? Is Java by the nature of the language just more suitable for an IDE/Code generated approach? Or am I lacking the knowledge to produce equal amounts of code "per Hand"?

  • Hablamos de Formación en la Conferencia Total Training en Lisboa

    - by Julio Rodriguez
    El pasado 22 de Octubre se celebro en Lisboa la 2ª Edición del Total Training Conference, la feria de la formación en la empresa de Portugal. Este año contó con la participación de cerca de 90 profesionales de los Recursos Humanos y se trataron los temas de mayor interés para los departamentos de formación de las empresas. ¿De qué se habló en la conferencia? Los ejes principales de las ponencias estuvieron centrados en la combinación de formación presencial y elearning, para sacar el máximo provecho de los presupuestos de formación y utilizar el medio adecuado para impactar de la manera más efectiva en los alumnos, ya estemos tratando de inculcar valores o comportamientos o simplemente transmitiendo una serie de conocimientos que tienen que ser utilizados en el día a día. Tambien se trato de los aspectos de aprendizajes informales, también conocidos como social learning, o cómo podemos transformar a nuestros empleados en profesores de sus compañeros resolviendo necesidades puntuales, pero a veces críticas. En la última ponencia se explicó y trató el novedoso tema de la gamificación o cómo introducir en la generación de contenidos formativos elementos lúdicos del juego para aumentar la efectividad de los mismos, concretando las definiciones y aclarando que formación no es una gamificación aunque por su similitud pueda confundirse. ¿Qué aportó Oracle a esta jornada? Desde Oracle quisimos aportar nuestro granito de arena, explicando los beneficios de una solución de formación en la nube, dónde, desde el punto de vista de funcionalidad no se renuncia a nada que pueda ofrecer una solución onpremise, con una serie de ventajas adicionales, como son: Pagar por uso y no hay que hacer desembolsos iniciales importantes como el pago de licencias o la compra de servidores o la contratación o asignación de personal informático para mantener un sistema en la casa. Así mismo al ser mantenida por el propio fabricante, el sistema es actualizado de forma constante, de forma transparente para el propio cliente sin los quebraderos de cabeza típicos de esos proyectos de implantación. Aprovechamos la ocasión para comentar algunos de los proyectos transformacionales de algunos de nuestros clientes para ilustrar como un sistema de formación puede por ejemplo convertir a un departamento que es un centro de coste en un centro de beneficio, o cómo un despliegue adecuado de la formación puede reducir la rotación, aumentar la satisfacción de los empleados y ayudar en el despliegue de nuevos productos. En definitiva una jornada de lo más provechosa si eres un profesional de la formación en Portugal Si quieres conocer las soluciones de elearning de Oracle las encontrarás aquí

  • Teach Your Kid to Code (&hellip;and Vote early!)

    - by Steve Michelotti
    Next Tuesday I will be at the CMAP main meeting presenting Teach Your Kid to Code. Next Tuesday is of course Election Day so you have to make sure you vote early in order to get over to CMAP for the 7:00PM presentation. I will be co-presenting this talk with my 5th grade son. Here is the abstract: Have you ever wanted a way to teach your kid to code? For that matter, have you ever wanted to simply be able to explain to your kid what you do for a living? Putting things in a context that a kid can understand is not as easy as it sounds. If you are someone curious about these concepts, this is a “can’t miss” presentation that will be co-presented by Justin Michelotti (5th grader) and his father. Bring your kid with you to CMAP for this fun and educational session. We will show tools you may not have been aware of like SmallBasic and Kodu – we’ll even throw in a little Visual Studio and Windows 8! Concepts such as variables, conditionals, loops, and functions will be covered while we introduce object oriented concepts without any of the confusing words. Kids are not required for entry! I promise this will be an entertaining presentation! We hope to see you (and your kids) there. Click here for details.

  • How do I get same scrollbar style for gtk-2.0 and gtk-3.0 apps?

    - by David López
    Sorry for my English mistakes, I'm Spanish. I'm using Ubuntu 11.10 in a tablet. I've removed overlay-scrollbars and I have increased the scrollbars size to use them with fingers. In /usr/share/themes/Ambiance/gtk-2.0/gtkrc I've changed: GtkScrollbar::slider-width = 23 GtkScrollbar::min-slider-length = 51 and added: GtkScrollbar::has-backward-stepper = 0 GtkScrollbar::has-forward-stepper = 0 In /usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css I've changed: GtkScrollbar-min-slider-length: 51; GtkRange-slider-width: 23; (in .scrollbar item) Now my scrollbars are usable with fingers, but they seem different for gtk-2.0 and gtk-3.0 apps. In the picture the left scrollbar is a gtk-2.0 app and the right one is a gtk-3.0 I want to setup gtk2.0 bar to be exactly the same as gtk3.0, that is Make upper and lower extremes empty (oranges circles in the picture) Reduce the length of the 3 horizontal lines (black ellipse) Can somebody help me? Thanks. Hola. Uso ubuntu 11.10 en una tableta; he quitado overlay-scrollbars y he incrementado el tamaño de las barras para poder usarlas con los dedos. Concretamente en /usr/share/themes/Ambiance/gtk-2.0/gtkrc be cambiado GtkScrollbar::slider-width = 23 GtkScrollbar::min-slider-length = 51 y añadido GtkScrollbar::has-backward-stepper = 0 GtkScrollbar::has-forward-stepper = 0 En /usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css he cambiado GtkScrollbar-min-slider-length: 51; GtkRange-slider-width: 23; (en el apartado.scrollbar) Mis barras son manejables con dedos, pero se ven muy distintas para aplicaciones gtk-2.0 y gtk-3.0.

  • Full Circle

    - by capgpilk
    Things have been a little bit hectic these past 6 months hence the lack of posts. My excuse is a good one though, my wife gave birth to our first son Tom back in September and it has been one hell of a rollercoaster ride since then. Things have settled back down now thank hevens.My last development gig didn't quite work out so now I have took the plunge and started contracting. It turns out my first contract is with the NHS trust that I started my development career with, which seems a bit wierd as that was 10 years ago. A lot has changed in the techniques and tools the NHS now use to develop with, there is a lot more .net with a slant towards the web side of the spectrum (at least in this NHS trust). They are really getting to grips with the MVC platform, so you will hopefully see some MVC posts coming up. The really suprising thing is that the Intranet I developed back in 2001 (classic asp migrated to .net 1.0) is still up and running and will finally be fazed out these coming weeks (to Sharepoint). It is like seeing an old friend all grown up.

  • Thank you South Florida for a successful SPSouthFLA

    - by Leonard Mwangi
    I wanted to officially thank the organizers, speakers, volunteers and the attendees of SharePoint Saturday South Florida. Being the first event in South Florida the reception was phenomenon and the group of speakers from keynote by Joel Oleson to session’s speakers from well renowned speakers like John Holliday, Randy Disgrill, Richard Harbridge, Ameet Phadnis, Fabian Williams, Chris McNulty, Jaime Velez to organizers like Michael Hinckley amongst others. With my Business Intelligence (BI) presentation being on the last track of the day, I spent very quality time networking with these great guys and getting the insider scope on International SharePoint Community from Joel and his son which was mesmerizing. I had a very active audience to a point where we couldn’t accommodate all the contents within the 1hr allocated time because they were very engaged and wanted a deep dive session on news features like PowerPivot, enhancements on PerformancePoint, Excel Services amongst others in order to understand the business value and how SharePoint 2010 is making the self-service BI become a reality. These community events allows the attendees experience technology first hand and network with MVPs, authors, experts providing high quality educational sessions usually for free which is a reason to attend. I have made the slides for my session available for download for those interested http://goo.gl/VaH5x

  • My Windows 8 App in Windows Store

    - by Stephen.Walther
    Finally, you have a good reason to upgrade to Windows 8! My Brain Eaters app was just accepted into the Windows Store. Just in time for Halloween! The Brain Eaters app is a sample app from my soon to be released book Windows 8 Apps with HTML5 and JavaScript. The game illustrates several important programming concepts which you need when building Windows 8 games with JavaScript such as using HTML5 Canvas and the new requestAnimationFrame() method. If you are looking for Halo or Call of Duty then you will be disappointed. If you are looking for PAC-MAN then you will be disappointed. I created the simplest arcade game that I could imagine so I could explain it in the book. All of the code for the game is included with the book. The goal of the game is to eat the food pellets while avoiding the zombies while running around a maze. Every time you get eaten by a zombie, you can hear my six year old son saying “Oh No!”. Here’s the link to the game: http://apps.microsoft.com/webpdp/app/brain-eaters/e283c8d0-1fed-4b26-a8bf-464584c9de6d

  • Ch-ch-ch-changes...

    - by Lou Vega
    The last few months have been pretty crazy. Just before the MVP summit in February I was approached about changing to a different project with my (then current) employer, and right after the summit I was approached by another company. Eventually I went with the new company and a new role in the Information Assurance field. More to come on that as things progress. All that being said I've not been as active in the .NET community as I once was and I miss it - so I'm looking to dive back in especially as Windows Phone 7 draws nearer and nearer. Speaking of the community - many of you may not recognize me if you see me now :) I had told my son for the last couple years that I would cut my hair before he turned 5 (he always asked how come he didn't have long hair) and he turns 5 (time has flown!) on June 19th so May 30th I cut my long hair down pretty short and donated the hair to Locks of Love. As Chris said to me on Twitter, "pics or it didn't happen" - well fortunately my wife was there to document the whole thing so I'll get a picture or two posted here soon.

  • Is there a command-line utility app which can find a specific block of lines in a text file, and replace it?

    - by fred.bear
    UPDATE (see end of question) The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :) UPDATE: ..(sub-update) My following comment about reasons when not use sed are only in the context of; don't push any tool too far beyond its design intent (I use sed quite often, and consider it to be invaluable.) I just now found an interesting web page about sed and when not to use it. So, because of all the sed answers, I"ll post the link.. it is part of the sed FAQ on sourceforge Also, I'm pretty sure there is some way diff can do the job of locating the block of text (once it's located, the replacement is quite straight foward; using head and tail) ... 'diff' dumps all the necessary data, but I haven't yet worked out how to filter it , ... (I'm still working on it)

  • Ubuntu 12.04 LTS won't install - never finishes please help

    - by Richard Higgins
    Want to try Ubuntu after using Windows for 30 years. Tried to install it 5 times on a Lenovo X120e notebook and twice on a Lenovo M57 desktop. No luck, worse than what Microsoft puts you through. I burned 12.04 LTS to disc. It installs up to the "Who Are You?" screen, then stops. Accepted the recommended computer name and lower case user name. I chose "log me in automatically." After that there is no progress bar, no rotating or pulsing button, nothing to indicate the Ubuntu has not died or fallen asleep. Is that how it is written? Never heard of a program that would take a long time to install while a user looked at a locked, dead screen. I just bought the M57 desktop for my son. It came with Ubuntu 10 something. I wanted to upgrade to 12.04 but it crashed, twice, to a DOS screen saying the pc lacked a certain "init" file. Various help screen commands did not help. On the X120e, I thought a partial-failed Ubuntu install was causing the problem, so I removed the drive and deleted the Ubuntu partition and replaced it. But same result. After I fill in my name, accept computer and user name, the "continue" button does not appear to work. I can go "back" but not forward. I have waited torturous hours. It doesn't take more than two hours to install, does it?any It is my own fault because of the high expectations I had for a sensible, hassle-free installation, but I am immensely disappointed. Thank you for any response

  • Is it possible to to have all pre-unity effects in latest ubuntu?

    I've been an Ubuntu dilettante for a long, long time. It is not my primary OS but I've always had it on all my laptops and desktop machines for over 8 years now. What I really, really like(d) about ubuntu (or linux, for that matter) was the effects - desktop cube, wobbly windows and other such "cool" effects. Needless to say, I was heartbroken with Unity. I gave it the benefit of doubt and tried to like it, tried to love it. Stuck with it for over a year. But I recently came to the conclusion that unity is really not for me. I want my old ubuntu back, with all it's eye candy effects. I tried messing around with ccsm but it only seemed to make the matters worse. Now, I could just install the old version of ubuntu - but getting my bamboo pen and Nvidia to work with it is a son of a.. anyway, the point is, old version of ubuntu is outdated to work with my newer machines. I'd rather have a new version of ubuntu but without unity- I don't know what the eye candy stuff is called - and so my question is this - Is it possible to rid ubuntu of unity and get all the eye candy stuff and if it is not possible, can you please advice me what other linux supports all the effects, please? I've searched high and low for unity alternatives but didn't find any satisfactory solutions; so I think my question is mainly about what other linux flavour is better suited for the task - sorry if it is out of topic.

  • Lubuntu 12.04 on Acer laptop boots to blank blue screen

    - by WGCman
    My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

  • ALPS touchpad stops working after reboot

    - by user58289
    I recently upgraded to 12.04 LTS. My Compaq Presario CQ-40 324la touchpad worked after first restarting after installation. But after restarting a second time, the touchpad is completely disabled, without having changed anything in the system. I've tried solutions but haven't had good results. The applications I've installed (fro "solutions" are: Pointing Devices Synaptiks Dconf-Tools I've also tried updating GRUB, adding this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux") I tried these commands in a terminal. Neither has worked. sudo modprobe -r psmouse sudo modprobe psmouse proto=imps El Touchpad ALPS se desactiva al reiniciar Recién he actualizado a Ubuntu 12.04LTS y a mi parecer ha mejorado mucho con respecto a 11.10... Pero ese no es mi punto ahora. El Touchpad funcionó correctamente luego del primer reinicio después de la instalación. Pero luego de volver a reiniciar, el Touchpad queda totalmente deshabilitado sin haber hecho cambio alguno en el sistema. He probado las soluciones en su mayoría y no he tenido buenos resultados. Las aplicaciones que he instalado (de las "soluciones") son: -Dispositivos apuntadores. -Synaptiks -DConf-Tools Y he intentado también actualizando el grub (añadiéndole una linea así: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux") Intenté en la terminal con el comando: sudo modprobe -r psmouse sudo modprobe psmouse proto=imps Ninguno me ha resultado bien. La laptop es Compaq Presario CQ-40 324la

  • Interview questions for programming tutor?

    - by Emmett Gear
    My family is looking for a programming/computer science tutor. Personally, I want to learn Java or some other brand of web programming. I am best described as a PC "power user." I have never programmed in the past and would like a good jump start. I am a very quick learner and do not expect the tutor to have to teach me the ultra basic stuff that I can learn myself. My son also needs a programming tutor. He just got into Carnegie Mellon as a computer science major. Having done only robotics and mathematics in the past he is very nervous that he does not have the same level of knowledge as his future classmates. I need some help coming up with a list of questions to ask potential tutors and some criteria to judge them by. Thanks! Edit: So far I have come up with just the obvious... Where did you receive your education? What languages are you familiar with? How long have you been tutoring? What made you decide to become a tutor? What software projects have you worked on? What work references can you give me? How much do you charge?
