  • Little PM side post...

    - by edgaralgernon
    When adding new team memebers... off set the ramp up time by 1) having pre built machines ready and and easy method of getting the lastest tools, code base etc. I'm fortunate enough to be at a client that has a machine ready built and loaded when the dev arrives, all they have to do is grab the code. 2) have tasks broken down so that dependencies are as minimal as possible. In other words, to over come the mythical man month issue (as recently mentioned on slashdot) make sure the tasks you hand out have few dependencies on each other. That way the new dev is able to be productive fairly quickly. Here's our historical lead time... the bump in Jan is due to added work, by 2/18 we had added 4 new people over the last two weeks. And amazing the time starts coming down: Here's our averag work time: again time ramps up as we are adding more tasks, but then starts inching back down through out Feb and March. It's not that we beat the Mythical Man Month, and in fact I still believe the book and idea are highly relevant. But if you can break the tasks down and reduce the dependencies between the task then you can mitigate the effect. The tool used in this case is from AgileZen.com and some of the wild swings are due to inexperience with the system initially... but our average times as measured by the tool are matching real life. Also the tool appearst to measure in 24 hour days and 7 day weeks. so it isn't as bad as it looks. :-)

  • How to make sysctl network bridge settings persist after a reboot?

    - by Zack Perry
    I am setting up a notebook for software demo purpose. The machine has 8GB RAM, a Core i7 Intel CPU, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit. The notebook is used as a KVM host and runs a few KVM guests. All such guests use the virbr0 default bridge. To enable them to communicate with each other using multicast, I added the following to the host's /etc/sysctl.conf, as shown below net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 Afterwards, following man sysctl(8), I issued the following: sudo /sbin/sysctl -p /etc/sysctl.conf My understanding is that this should make these settings persist over reboots. I tested it, and was surprised to find out the following: root@sdn1 :/proc/sys/net/bridge# more *tables :::::::::::::: bridge-nf-call-arptables :::::::::::::: 1 :::::::::::::: bridge-nf-call-ip6tables :::::::::::::: 1 :::::::::::::: bridge-nf-call-iptables :::::::::::::: 1 All defaults are coming back! Yes. I can use some kludgy "get arounds" such as putting a /sbin/sysctl -p /etc/sysctl.conf into the host's /etc/rc.local but I would rather "do it right". Did I misunderstand the man page or is there something that I missed? Thanks for any hints. -- Zack

  • More Retro Games

    - by Matt Christian
    Last week I made 2 stops to my local game stores and spent a load of cash on a bunch of new retro games for my collection.  Here are the recent additions: NES - Mega Man 2 - The Adventures of Bayou Billy - Ducktales - Metal Gear - Super Mario Bros / Duck Hunt - Firestorm - Dragon's Lair - Bartman Meets Radioactive Man N64 - Superman 64 - Zelda: Ocarina of Time (in original box, box is in poor condition) Atari - Superman - Adventure - Donkey Kong - Raiders of the Lost Ark Dreamcast - Memory card with view screen - Space Channel 5 Genesis (all in case) - Jurassic Park - Sonic Spinball - Sonic the Hegehog 3 (missing manual) - Spiderman (also called Spiderman vs. The Kingpin) GameGear - Bart vs The Space Mutants Quite a large haul given it was all purchased in 2 days.  Although, Metal Gear I got for a great deal and almost considered buying their other copy simply to resale for more though I decided against it to let another lucky soul find it.  I may need to run over there again because I think they had TMNT 2 (NES) for around $6 and it usually sells for more than that.  I could have sworn I grabbed it and bought it but my receipt tells me differently. I also found my copy of Super Mario 3 and added that to my collection.  Unfortunately one of the corners of the label has begun to peel up pretty badly which sucks although it's still a good item for the collection. In other retro news, this weekend was Easter and while at my grandparents the cousins wanted to play on their NES which was not working.  Me being the retro NES nerd I am, grabbed a screw driver, some Windex, a few toothpicks, and a few cotton swabs and had it up and running under an hour (that includes eating dinner!).  The NES holds the games tighter, has a better connection, and works almost instantly.  I should do THAT for a living!

    @pevansgreenwood: People don’t like change. (Or do they?) "Creating a culture that embraces change, means changing the way we think about and structure our organisations and our careers. It means rethinking the rules of enterprise IT." -- Peter Evans Greenwood (tags: enterprisearchitecture change innovation) Karim Berrah: After IRON MAN 2 "Nice demo of a robot serving a cup of coffee, from a Swiss based engineering company, NOSAKI, I visited last week. This movie is not a fiction (like IRON MAN 2) and is really powered by an Oracle Database." -- Karim Berrah (tags: oracle solaris ironman2 nosake) @myfear: Spring and Google vs. Java EE 6 "While Spring and Rod Johnson in particular have been extremely valuable in influencing the direction of Java (2)EE after the 1.4 release to the new, much more pragmatic world of Java EE 5, Spring has also caused polarization and fragmentation.

  • Welcome to JavaOne!

    - by marius.ciortea
    Welcome to this year's JavaOne conference! We are glad you dropped by. We want to keep you informed of all the happenings around JavaOne: all the events leading up to the conference and all the events during the conference week itself. We'll cover announcements, news, planning (but we won't make you go to any meetings), and snafus (nothing that makes us look too bad, of course). We'll even throw in a contest or two to make sure you are paying attention. We'll post a couple of times a week, and then more frequently as we get closer to September. There's a group of us, and we cover the Java beat, JUGs, Oracle Technology Network, Oracle Solaris, and lots more. What do you want to hear about? Let us know.A group of us from the office went to see the movie Iron Man 2 (it just debuted in the United States) last week and it reminded us of Java, the Java community, and JavaOne. In all three cases, from many disparate (and sometimes seemingly incompatible) parts and people, something comes together that works, is cool, and helps make a better world. Right now, there are hundreds of little islands of planning, all busy answering questions for JavaOne: What sessions get selected? What goes in the Mason street tent (until a few weeks ago, Will there be a tent on Mason street?), What do the JUGS need? Which Oracle ACEs will be there? Can we do a surf theme at the OTN party? And, somehow, like an Iron Man suit, they all come together and work to make a great event. At least, we hope it will be great. That's for you to decide. Please don't be shy--give us your comments and suggestions. We'll be listening.P.S. You can attend Stark Expo online at Oracle.com/ironman2, where you can train to become a "Master Cloud Operative." I got my MCO certification. I wish I had a card to put in my wallet.

  • Future Air Plane – A new world

    - by Rekha
    For the first time in my life, I wished I had more number of years to live. The world has evolved from the cave man life to the man who is almost The Creator. When I was about 12 years old, I was taken to Chennai Planetarium for my school excursion. That day we were made to lie down in a dark room and the ceiling was full of stars and planets. All those were just videos but the day still stands in my mind. Same kind of experience in real is waiting for our future generations.Even though the English movies have gone beyond imaginations, we still have chances to bring those imaginations to real. You must be wondering why all these hype. Recently Airbus unveiled a news on transparent Airplane in 2050. This Airplane will have a body transparent to view the sky from all sides of the airplane when we are flying high above the grounds. And it will have all possible technologies under one roof that would give immense pleasure for the passengers. The journey would be an unforgettable one for each one of us. Image and News Credit: Daily Telegraph This article titled,Future Air Plane – A new world, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

  • Daten versionieren mit Oracle Database Workspace Manager

    - by Heinz-Wilhelm Fabry (DBA Community)
    Wie können extrem lange Transaktionen durchgeführt werden, also Transaktionen, die Datensätze über Stunden oder Tage exklusiv sperren, ohne dass diese langen Transaktionen 'normale' Transaktionen auf diesen Datensätzen behindern? Solche langen Transakionen sind zum Beispiel im Spatial Umfeld keine Seltenheit. Wie können unterschiedliche historische Zustände von Produktionsdaten online zeitlich unbegrenzt vorgehalten werden? Die UNDO Daten, die das gesamte Änderungsvolumen einer Datenbank vorhalten, gewährleisten in der Regel nur einen zeitlich sehr limitierten Zugriff auf 'ältere' Daten. Und die Technologie der database archives, auch bekannt unter dem Namen Total Recall, erlaubt einerseits keine Änderungen an den älteren Daten und steht andererseits ausschließlich in der Enterprise Edition der Datenbank zur Verfügung. Wie kann man die aktuellsten Produktionsdaten für WHAT-IF-Analysen verändern und währenddessen andere Benutzer ungestört auf den Originaldaten weiterarbeiten lassen? Ein SET TRANSACTION READ ONLY erlaubt keinerlei Änderungen und ist ebenfalls begrenzt auf die 'Reichweite' der UNDO Informationen. Zwar könnte man für derartige Analysen eine Datenbankkopie aus dem Backup aufbauen oder eine Standby Lösung implementieren, aber das ist doch eher aufwändig. Es gibt eine verblüffend einfache Antwort auf diese scheinbar komplizierten Fragen. Sie heisst Oracle Database Workspace Manager oder kurz Workspace Manager (WM). Der WM ist ein Feature der Datenbank seit Oracle9i, das sowohl in der Standard als auch in der Enterprise Edition zur Verfügung steht. Anders als in den ersten Versionen ist er längst auch Bestandteil jeder Installation. Um so erstaunlicher ist es, dass so wenige Kunden ihn kennen. Dieser Tipp soll dazu beitragen, das zu ändern.

  • Ein Vortrag für die DOAG 2012?

    - by Franz Haberhauer
    Vom 20. bis 22. November findet in Nürnberg wieder die DOAG 2012 statt, die jährliche Konferenz der Deutschen Oracle Anwendergruppe e.V. - mithin die größte Veranstaltung rund um Oracle in Europa. Seit zwei Jahren ist dort auch Solaris ein Kernthema.Während in den ersten beiden Jahren Sprecher von Oracle den überwiegenden Teil der Vorträge zu Solaris gehalten haben, ist der Grundgedanke der Konferenz - und sicher ein wesentlicher Grund für viele der über 2000 Teilnehmer nach Nürnberg zu kommen - der Austausch von Erfahrungen zwischen Anwendern ergänzt durch Beiträge seitens Oracle. Dazu bedarf es natürlich der Anwender, die über ihre Erfahrungen berichten Der Call for Presentations ist gerade erschienen und offen bis zum 30. Juni. Man kann sich also in aller Ruhe Gedanken über mögliche Themen machen und vielleicht während eines Projektes die eine oder andere Notiz machen, um dann bei der Konferenz über Erfahrungen zu berichten. Solaris ist Teil des sogenannten Streams Infrastruktur und auf der Seite dazu findet sich vielleicht auch noch die eine oder andere Anregung für mögliche Themen. Erfahrungen rund um Solaris 11 sind sicher ein dankbares Themenfeld. Ein Vorteil für Referenten besteht im freien Eintritt zur gesamten Veranstaltung. Für Consultants und Partner mag es auch eine Motivation sein, im eigenen Spezialgebiet Kompetenz zu zeigen und sichtbar zu werden. Und wer keinen Vortrag einreichten will, mag sich vielleicht als Konferenzbesucher schon mal den Termin notieren: 20. bis 22. November 2012 in Nürnberg - man sieht sich

  • Flashback Database

    - by Sebastian Solbach (DBA Community)
    Flashback Database bezeichnet die Funktionalität der Oracle Datenbank, die Datenbank zeitlich auf einen bestimmten Punkt, respektive eine bestimmte System Change Number (SCN) zurücksetzen zu können - vergleichbar mit einem Rückspulknopf eines Kassettenrekorders oder der Rücksetztaste eines CD-Players. Mag dieses Vorgehen bei Produktivsystemen eher selten Einsatz finden, da beim Rücksetzten alle Daten nach dem zurückgesetzten Zeitpunkt verloren wären (es sei denn man würde dieser vorher exportieren), gibt es gerade für Test- oder Standby Systeme viele Einsatzmöglichkeiten: Rücksetzten des Systems bei fehlgeschlagenen Applikations-Upgrade Alternatives Point in Time Recovery (PITR) mit anschließendem Roll Forward (besonders geeignet bei Standby Systemen) Testdatenbank mit definiertem, reproduzierbaren Ausgangspunkt (z.B. für Real Application Testing) Datenbank Upgrade Test Einige bestehende Datenbank Funktionalitäten verwenden Flashback Database implizit: Snapshot Standby Reinstanziierung der Standby (z.B. bei Fast Start Failover) Obwohl diese Funktionalität gerade für Standby Systeme und Testsysteme bestens geeignet ist, gibt es eine gewisse Zurückhaltung Flashback Database einzusetzen. Eine Ursache ist oft die Angst vor zusätzlicher Last, die das Schreiben der Flashback Logs erzeugt, sowie der zusätzlich benötigte Plattenplatz. Dabei ist die Last im Normalfall relativ gering (ca. 5%) und auch der zusätzlich benötigte Platz für die Flashback Logs lässt sich relativ genau bestimmen. Ebenfalls wird häufig nicht beachtet, dass es auch ohne das explizite Einschalten der Flashback Logs möglich ist, einen garantieren Rücksetzpunkt (Guaranteed Restore Point kurz GRP) festzulegen, und die Datenbank dann auf diesen Restore Point zurückzusetzen. Das Setzen eines garantierten Rücksetzpunktes funktioniert in 11gR2 im laufenden Betrieb. Wie dies genau funktioniert, welche Unterschiede es zum generellen Einschalten von Flashback Logs gibt, wie man Flashback Database monitoren kann und was es sonst noch zu berücksichtigen gibt, damit beschäftigt sich dieser Tipp.

  • Http handler for classic ASP application for introducing a layer between client and server

    - by JPReddy
    I've a huge classic ASP application where in thousands of users manage their company/business data. Currently this is not multi-user so that application users can create users and authorize them to access certain areas in the system. I'm thinking of writing a handler which will act as middle man between client and server and go through every request and find out who the user is and whether he is authorized to access the data he is trying to. For the moment ignore about the part how I'm going to check the authorization and all that stuff. Just want to know whether I can implement a ASP.net handler and use it as middle man for the requests coming for a asp website? I just want to read the url and see what is the page user is trying to access and what are the parameters he is passing in the url the posted data. Is this possible? I read that Asp.net handler cannot be used with asp website and I need to use isapi filter or extensions for that and that can be developed only c/c++. Can anybody through some light on this and guide me whether I'm in the right direction or not?

  • How to choose how to store data?

    - by Eldros
    Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime. - Chinese Proverb I could ask what kind of data storage I should use for my actual project, but I want to learn to fish, so I don't need to ask for a fish each time I begin a new project. So, until I used two methods to store data on my non-game project: XML files, and relational databases. I know that there is also other kind of database, of the NoSQL kind. However I wouldn't know if there is more choice available to me, or how to choose in the first place, aside arbitrary picking one. So the question is the following: How should I choose the kind of data storage for a game project? And I would be interested on the following criterion when choosing: The size of the project. The platform targeted by the game. The complexity of the data structure. Added Portability of data amongst many project. Added How often should the data be accessed Added Multiple type of data for a same application Any other point you think is of interest when deciding what to use. EDIT I know about Would it be better to use XML/JSON/Text or a database to store game content?, but thought it didn't address exactly my point. Now if I am wrong, I would gladely be shown the error in my ways.

  • two thoughts about career excellence

    - by john.rose
    I love Dickens, warts and all. Sometimes he is sententious, and (like the mediocre modern I am) at such points I am willing to listen non-ironically. This bit here struck me hard enough to stop and write it down: I mean a man whose hopes and aims may sometimes lie (as most men's sometimes do, I dare say) above the ordinary level, but to whom the ordinary level will be high enough after all if it should prove to be a way of usefulness and good service leading to no other. All generous spirits are ambitious, I suppose, but the ambition that calmly trusts itself to such a road, instead of spasmodically trying to fly over it, is of the kind I care for. It is Woodcourt's kind. (John Jarndyce to Esther Summerson, Bleak House, ch. 60) Woodcourt is, of course, one of the heroes of the story. It is a heroism that is attractive to me. Here is a similar idea, from the Screwtape Letters. In the satirically inverted logic of that book, the “Enemy” is God, the enemy of the devils but the author of good: The Enemy wants to bring the man to a state of mind in which he could design the best cathedral in the world, and know it to be the best, and rejoice in the, fact, without being any more (or less) or otherwise glad at having done it than he would be if it had been done by another. (C.S. Lewis, Screwtape Letters, ch. 14) Though I will be happy with a good Bazaar, I also dream of Cathedrals. Put whatever name you like on it, as long as I get some part in the fun of building a good one.

  • Very basic beginner Ruby question to do with elsif and ranges [migrated]

    - by MattKneale
    I've been trying to get to grasps with Ruby (for all of an hour) and this is my first language. I've got the following code: var_comparison = 5 print "Please enter a number: " my_num = Integer(gets.chomp) if my_num > var_comparison print "You picked a number greater than 5!" elsif my_num < var_comparison print "You picked a number less than 5!" elsif my_num > 99 print "Your number is too large, man." else print "You picked the number 5!" end Clearly the interpreter has no way of distinguishing between accepting the rule 5 or 99. How do I make it so that any number between 6-99 returns "You picked a number greater than 5!", but a number 100 or greater returns "Your number is too large, man!"? Do I need to specifically state a range somehow? How would I best do that? Would it by the normal range methods e.g. if my_num 6..99 or if my_num.between(6..99) ?

Also, see firsthand several new enhancements we are adding to SQL Azure based on the feedback we&#x2019;ve received from the community since launching the service earlier this year.</summary> <published>2010-01-25T00:00:00-05:00</published> <updated>2010-03-05T01:07:05-05:00</updated> <author> <name /> </author> <link rel="edit" title="Session" href="Sessions(guid'816995df-b09a-447a-9391-019512f643a0')" /> <link rel="http://schemas.microsoft.com/ado/2007/08/dataservices/related/Speakers" type="application/atom+xml;type=feed" title="Speakers" href="Sessions(guid'816995df-b09a-447a-9391-019512f643a0')/Speakers"> <m:inline> <feed> <title type="text">Speakers</title> <id>http://api.visitmix.com/OData.svc/Sessions(guid'816995df-b09a-447a-9391-019512f643a0')/Speakers</id> <updated>2010-03-25T11:56:06Z</updated> <link rel="self" title="Speakers" href="Sessions(guid'816995df-b09a-447a-9391-019512f643a0')/Speakers" /> <entry> <id>http://api.visitmix.com/OData.svc/Speakers(guid'3395ee85-d994-423c-a726-76b60a896d2a')</id> <title type="text">David-Robinson</title> <summary type="text"></summary> <updated>2010-03-25T11:56:06Z</updated> <author> <name>David Robinson</name> </author> <link rel="edit-media" title="Speaker" href="Speakers(guid'3395ee85-d994-423c-a726-76b60a896d2a')/$value" /> <link rel="edit" title="Speaker" href="Speakers(guid'3395ee85-d994-423c-a726-76b60a896d2a')" /> <link rel="http://schemas.microsoft.com/ado/2007/08/dataservices/related/Sessions" type="application/atom+xml;type=feed" title="Sessions" href="Speakers(guid'3395ee85-d994-423c-a726-76b60a896d2a')/Sessions" /> <category term="EventModel.Speaker" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" /> <content type="image/jpeg" src="http://live.visitmix.com/Content/images/speakers/lrg/default.jpg" /> <m:properties xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices"> <d:SpeakerID m:type="Edm.Guid">3395ee85-d994-423c-a726-76b60a896d2a</d:SpeakerID> <d:SpeakerFirstName>David</d:SpeakerFirstName> <d:SpeakerLastName>Robinson</d:SpeakerLastName> <d:LargeImage m:null="true"></d:LargeImage> <d:SmallImage m:null="true"></d:SmallImage> <d:Twitter m:null="true"></d:Twitter> </m:properties> </entry> </feed> </m:inline> </link> <link rel="http://schemas.microsoft.com/ado/2007/08/dataservices/related/Tags" type="application/atom+xml;type=feed" title="Tags" href="Sessions(guid'816995df-b09a-447a-9391-019512f643a0')/Tags" /> <link rel="http://schemas.microsoft.com/ado/2007/08/dataservices/related/Files" type="application/atom+xml;type=feed" title="Files" href="Sessions(guid'816995df-b09a-447a-9391-019512f643a0')/Files" /> <category term="EventModel.Session" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" /> <content type="application/xml"> <m:properties> <d:SessionID m:type="Edm.Guid">816995df-b09a-447a-9391-019512f643a0</d:SessionID> <d:Location>Breakers L</d:Location> <d:Type>Seminar</d:Type> <d:Code>SVC07</d:Code> <d:StartTime m:type="Edm.DateTime">2010-03-17T12:00:00</d:StartTime> <d:EndTime m:type="Edm.DateTime">2010-03-17T13:00:00</d:EndTime> <d:Slug>SVC07</d:Slug> <d:CreatedDate m:type="Edm.DateTime">2010-01-26T18:14:24.687</d:CreatedDate> <d:SourceID m:type="Edm.Guid">cddca9b7-6830-4d06-af93-5fd87afb67b0</d:SourceID> </m:properties> </content> </entry> I want to print the: Session Title (Building Web Applications with Microsoft SQL Azure) The Author (David Robinson) The Location (Breakers L) And display the speakers image (http://live.visitmix.com/Content/images/speakers/lrg/default.jpg) I presume I can use filegetcontents and then transform to simplexmlstring, but I dont know how to get the deeper items in I want, like Author, and image. Any chance of a bit of coding genius here?

  • Recursive TreeView in ASP.NET

    - by waqasahmed
    I have an object of type list from which I wish to use to populate a treeview in asp.net c#. Each object item has: id | Name | ParentId so for example: id | Name | ParentId ------------------------- 1 | Alice | 0 2 | Bob | 1 3 | Charlie | 1 4 | David | 2 In the above example, the parent would be Alice having two children Bob and Charlie. David is the child of Bob. I have had many problems trying to dynamically populate the treeview recursively in c# ASP.NET Does any one have a simple solution? Btw: you can use People.Id, People.Name and People.ParentId to access the members since it is an object belonging to list. I can post you my code so far (many attempts made) but not sure how useful it will be.

  • SQL Count Query with Grouping by multiple Columns

    - by Christian
    I have a table with three filled columns named "Name", "City" and "Occupation". I want to create a new column in the same table that contains the number of people who have the same occupation. "Name" | "City" | "Occupation" ------------------------------ Amy | Berlin | Plumber Bob | Berlin | Plumber Carol | Berlin | Lawyer David | London | Plumber I want to have a table that contains: "Name" | "City" | "Occupation" | "Number" --------------------------------------- Amy | Berlin | Plumber | 2 Bob | Berlin | Plumber | 2 Carol | Berlin | Lawyer | 1 David | London | Plumber | 1 How does the SQL Query that creates the new columns have to look like? I want to actually create a new column in the database that I can access later.

  • How to compare the output of serializeArray using qunit

    - by dorelal
    I am using qunit and jquery. Latest version of both. In my code when I submit the form I have the event as e. I call e.serializeArray() Here is my test. equals(args.data, [ { "name": "user_name", "value": "john" } ], 'input data'); And this is the error message from qunit. expected: [ { "name": "user_name", "value": "david" } ] result: [ { "name": "user_name", "value": "david" } ] As you can see to the naked eye the expected and result value is same but qunit is not liking it. I guess I am missing something.
