Today I went to the Black Hat Sessions 2017 in Ede (NL). I must say that the overall quality of the sessions was a bit less appealing than last year, but there was some interesting stuff out there. Especially the keynote by Bill Cheswick on the subject of “data”, and a session by Duncan Campbell called “A century of data stealing”, gave me a lot food for thought. Recordings of the videos will become available at https://www.

The first victims of the new owner of Vancis (a Dutch cloud company) have fallen? Investors … I never know what to think of them. Our society relies too much on them, that’s for sure. 19 people laid off. That is just one short of a complex redundancy procedure. Coincidence? I think it’s just a way of doing business. I wish all the people fired luck finding a respectful employer.

After shipping, a month ago from the UK, today my Raspberry Zero finally arrived. Besides the Rzero I also ordered a Zero Essentials Kit because of the HDMI converter and some nice 90 degrees header. I’m not a huge fan of the Raspberries, but I had to buy this one because of the formfactor. Normally I prefer the Banana Pros a lot more than the Raspberries. Not sure what the thing will be used for, but it looks nice.

If you want to automaticly clear the PXE advertisements of a certain age, you can use the Powershell script below to clear them. The script determines what advertisements are OK to clear, using a WQL query. Please note…timing logic works accurate if you keep $minutesBeforeAction < 60. Otherwise you might need to alter the logic a bit. Have fun Import-Module"C:\Program Files (x86)\Microsoft\Configuration Manager\AdminConsole\bin\ConfigurationManager.psd1"$siteServer="localhost"$siteCode="SITECODE"$minutesBeforeAction=15$query="select lastPXEAdvertisementTime, NetbiosName from SMSLastPXEAdvertisement"$formattedTime=bigint.ToString("yyyyMMddhhmmss")cd"$($siteCode)="$PXEAdvertisements=Get-WmiObject-Query$query-Namespace"ROOTSMSsite$siteCode"-ComputerName"$siteServer"foreach($PXEAdvertisementin$PXEAdvertisements){$simpleLastPXEAdvertisementTime=[bigint]$PXEAdvertisement.LastPXEAdvertisementTime.Split(".")[0]if($formattedTime-$simpleLastPXEAdvertisementTime-gt($minutesBeforeAction*100)){Clear-CMPxeDeployment-DeviceName$PXEAdvertisement.NetbiosName}}

Today Eloísa Romero sent me an email presenting me her EzTemp&RH crowdfunding project. I really like it. It takes away a lot of the hassle you encounter when measuring temperature and humidity. It also features some quite precise components, including an auxiliary connection for an additional sensor of your choice. Great for a Raspberry Pi! Take a look at the projectsite. https://www.indiegogo.com/projects/easy-temperature-and-humidity-for-raspberry-pi

Cresta TX320 longer antenna

Fixing a better transmission on a TX320

Last week I bought 5 sensors of the type Cresta TX320 for my Domoticz system. Unfortunately they have a very weak transmitting signal strength. One HR++ glass pane and a concrete floor is too much to reach the RFXTRX433e transceiver. I removed the old internal antenna and exchanged it with a solid wire matching the length of 1⁄4 of the wavelength of the 433Mhz band. That is 17,3 cm from the PCB to the end of the wire.
