Clean Code

Clean Code (A Handbook of Agile Sortware Craftmanship) by Robert C. Martin is a must-read. Here are a few notes about it (filtered).

Regasm : insufficient system resources

Got this error at work :

Regasm : error RA0000 : Insufficient system resources exist to complete the requested service

I played a little with procmon (Thanks a lot Mark !) I looked for "INSUFFICIENT RESOURCES" in the events. This event was due to a RegCreateKey in HKCR/Wow6432Node/CLSID. It turned out that it was not possible to create a subkey with regedit. HTH

How To Really Reset Folder Settings in Windows 7

Sometimes, Windows 7 automatically updates explorer's columns. For example, if a folder has a mp3 file, columns headers will be artist, song, etc. This is really annoying for all other files of the same folder. Configuration is stored in registry. Deleting and creating again such a folder will not reset its configuration. You have to delete keys in registry. Here is the .reg file found on sevenforums.com :

Windows Registry Editor Version 5.00

Windows 7 sp1 [Solved]

Windows update fails to install service Windows 7 sp1. After downloading the 900 MB of windows6.1-KB976932-X64.exe (I also downloaded Windows_Win7SP1.7601.17514.101119-1850.AMD64CHK.Symbols.msi and Windows_Win7SP1.7601.17514.101119-1850.AMD64FRE.Symbols.msi, almost 300 MB each but I am still not sure about the requirement of these two), I tried to update manually. But this failed again : "L'installation n'a pas réussi", "l'assembly n'a pas pu être trouvé". "Détails" do not give a lot more info : "Erreur : ERROR_SXS_ASSEMBLY_MISSING(0x80073701)". There is a link to get more info ("Se connecter pour en savoir plus sur ce problème"), but this does not help me solve this problem.

Found the same problem here and here.

Looking deeper in C:\Windows\Logs\CBS\CBS.log (>250 MB) :

I think the important part is Package_43_for_KB976098~31bf3856ad364e35~amd64~~6.1.1.1. So I tried to download KB976098 for x64 and install it manually, but windows tells me it is already installed.

• sfc /scannow found nothing.
• System Update Readiness Tool (KB947821 [v14]) does not help either (cannot install).

I eventually managed to install SP1 thanks to Kris post : I had to remove 4 KB : KB976098, KB979306, KB981793 and KB979916. Problem solved !

Argotic Syndication Framework Desillusion

When I discovered Argotic Syndication Framework a few hours ago, I thought : One to rule them all. They say on their web site that I don't have to speak the syndication langage. But, I failed to make it work on the first syndication feeds I tried : blog.free.fr atom feeds generated with dotclear raise the following exception :

   at Argotic.Common.Guard.ArgumentNotNullOrEmptyString(String value, String name)
   at Argotic.Syndication.AtomPersonConstruct.set_Name(String value)
   at Argotic.Syndication.AtomPersonConstruct.Load(XPathNavigator source)
   at Argotic.Syndication.AtomPersonConstruct.Load(XPathNavigator source, SyndicationResourceLoadSettings settings)
   at Argotic.Data.Adapters.Atom10SyndicationResourceAdapter.FillFeedCollections(AtomFeed feed, XPathNavigator source, XmlNamespaceManager manager, SyndicationResourceLoadSettings settings)
   at Argotic.Data.Adapters.Atom10SyndicationResourceAdapter.Fill(AtomFeed resource)
   at Argotic.Data.Adapters.SyndicationResourceAdapter.FillAtomResource(ISyndicationResource resource, SyndicationResourceMetadata resourceMetadata)
   at Argotic.Data.Adapters.SyndicationResourceAdapter.Fill(ISyndicationResource resource, SyndicationContentFormat format)
   at Argotic.Syndication.AtomFeed.Load(XPathNavigator navigator, SyndicationResourceLoadSettings settings, SyndicationResourceLoadedEventArgs eventData)
   at Argotic.Syndication.AtomFeed.Load(Uri source, ICredentials credentials, IWebProxy proxy, SyndicationResourceLoadSettings settings)
   at Argotic.Syndication.AtomFeed.Create(Uri source, ICredentials credentials, IWebProxy proxy, SyndicationResourceLoadSettings settings)
   at Argotic.Syndication.AtomFeed.Create(Uri source, SyndicationResourceLoadSettings settings)
   at Argotic.Syndication.AtomFeed.Create(Uri source)

It fails to parse publication dates in Univers Freebox syndication feeds or Slashdot feeds. Well, it seems I have to learn this langage anyway... Edit : After failing again on slashdot feeds with .NET 3.5 classes, I found Peter's blog. Actually my code was getting closer to his solution.

Merci à la TVA !

Les opérateurs profitent de la hausse de la TVA pour augmenter les tarifs des téléphones. Il y a deux semaines, on pouvait avoir un forfait Bouygues Telecom Evasio 1h+1h à 34 € (engagement d'un an), avec un HTC Desire pour :

• phoneandphone : 1 € - Aujourd'hui : 169 €
• BT : 59 € - Aujourd'hui : 180 €

Voleurs ! Mais bon, il suffit de se détendre ! 51 € en blanc :^( chez Virgin Mobile avec le code promo DESIRE et le forfait E-Devine à 31 €.
