leave a comment »

Some good papers and solutions

  1. Oracle Application Express Deployment http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-deploy-installation-1878444.html
  2. Oracle Application Express 4.2 Downloads http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html
  3. Thread: help to upgrade to version 4.1 of apex
    1. In my 10g XE installation (upgrade from 4.0.2 ) I did ( in this order ):  https://forums.oracle.com/forums/thread.jspa?threadID=2273952
      install SQL> @apexins SYSAUX SYSAUX TEMP /i/
    2. upgrade img folder SQL> @apxldimg.sql c:\oraclexebe sure about correct location for image files in ..\apex\img
      old 1: create directory APEX_IMAGES as ‘&1/apex/images’
      new 1: create directory APEX_IMAGES as ‘/mnt/hgfs/vm_share/apex/images’ — make sure here is the right directory….
      https://forums.oracle.com/forums/thread.jspa?threadID=2358765if you need to change admin user password.
      SQL> @apxchpwd
      Enter a value below for the password for the Application Express ADMIN user.
    3. removing prior installationsfinding old installations
      SELECT username FROM dba_users
      WHERE (username LIKE ‘FLOWS_%’ OR USERNAME LIKE ‘APEX_%’)
      AND USERNAME NOT IN ( SELECT ‘FLOWS_FILES’ FROM DUAL
      UNION
      SELECT ‘APEX_PUBLIC_USER’ FROM DUAL
      UNION
      SELECT SCHEMA s FROM dba_registry WHERE comp_id = ‘APEX’);removing old installations. DROP USER APEX_040000 CASCADE;—-
      Notes:My installation – apex 4.1 unzipped – resides in:c:\oraclexe\apex — no empty apex folder in apex main folder

      always loggin in as :

      sqlplus system/password as sysdba

      Final Result: works fine. Elapsed: 00:39:38.50

…Real world code sucks…

leave a comment »

Some citations from “What Compsci textbooks don’t tell you: Real world code sucks” By Dave MandlGet more from this author Posted in Developer, 21st December 2012 10:19 GMT @ http://www.theregister.co.uk/2012/12/21/financial_software_disasters/?utm_source=dlvr.it&utm_medium=linkedin&goback=.gde_35521_member_199777473  :

“There’s a kind of cognitive dissonance in most people who’ve moved from the academic study of computer science to a job as a real-world software developer. The conflict lies in the fact that, whereas nearly every sample program in every textbook is a perfect and well-thought-out specimen, virtually no software out in the wild is, and this is rarely acknowledged.”

… — it’s outright terrible by any number of measures.

“Of course there are many exceptions, but they’re just that: exceptions. In my experience, software is, almost as a rule, bad in one way or another. And lest I be accused of over-generalising: in more than 20 years I’ve done work for maybe a dozen companies, almost all of them in the banking industry and many of them household names.”

“Complex systems + borked code = beelllions down the drain: In the financial business there have been several software-related blowups in the last few years that were big enough to make it onto the evening news. To name just three, there were: the Nasdaq failure that wreaked havoc with Facebook’s IPO; a trading fiasco at Knight Capital in August that led to widespread market disruption and a $400m drop in Knight’s market value; and the “flash crash” of May, 2010, which caused market losses of at least $1 trillion in a matter of minutes.”

“…startups can’t find people with even basic coding skills…”

Few quotes only from the

UHLENHUTH: Making Yale comp sci relevant

“The department’s decision has repercussions outside of the Yale bubble as well. By failing to provide practical programming classes, Yale is contributing to New Haven’s economic irrelevance. When startups can’t find people with even basic coding skills, they leave New Haven for the greener pastures of Boston and Silicon Valley. As former president of the Yale Entrepreneurial Society, I saw countless Yale student startups sputter and die without because they couldn’t find a technically proficient co-founder. Less than 10 percent of ventures had founders that could actually build a product.””The good news is that there’s an easy first step that Yale computer science could take to start addressing this issue. It pains me to say it, but we could learn a thing or two from a certain institution in Cambridge. One thing that Harvard has absolutely gotten right is its introductory CS50 class that teaches students of all majors the practical scripting and Web programming skills they need to apply tech to their other interests. My sister — who chose Harvard over Yale partially because of classes like CS50 — started the semester knowing almost nothing about programming and finished with a job offer from a tech startup. She might not even end up being a computer science major, but the class gave her a solid set of skills that she’s already putting to work.”

Think about it!

Businesses Worry About Christmas Day Attacks by By Fahmida Y. Rashid December 24, 2012 – PCMag.com

leave a comment »

“In an online survey of 270 security and IT professionals, about 57 percent said their companies may be more vulnerable to security attacks during major holidays such as Christmas or New Year’s. Breaking down by job function found that 61 percent of security professionals were concerned, compared to 54 percent of business stakeholders. The survey, which was conducted between Nov. 8 and Nov. 19, was commissioned by nCircle and conducted by Dimensional Research.” http://www.pcmag.com/article2/0,2817,2413540,00.asp
