Enterprisersproject: Four tips for women in tech to rise above career stereotypes and succeed in the workplace.
I decided to setup a DHCP & DNS server on my Ubuntu Server 14.04 at home. Primarily just for educational purposes, but it is useful, albeit a bit overkill, for my home network.
After spending 2 nights working through some stupid permissions issues related to our buddy apparmor, I finally got to where there are no errors and everything looks as it should:Mar 23 21:24:38 ubuntu-gateway dhcpd: DHCPDISCOVER from 44:85:00:4d:49:37 via eth0 Mar 23 21:24:39 ubuntu-gateway dhcpd: DHCPOFFER on 192.168.10.119 to 44:85:00:4d:49:37 (MMMM- LENOVO) via eth0 Mar 23 21:24:39 ubuntu-gateway named: client 192.168.10.22#56110/key rndc-key: signer "rndc-key" approved Mar 23 21:24:39 ubuntu-gateway named: client 192.168.10.22#56110/key rndc-key: updating zone 'linux.xxxx/IN': adding an RR at 'MMMM-LENOVO.linux.mxxxx' A Mar 23 21:24:39 ubuntu-gateway named: client 192.168.10.22#56110/key rndc-key: updating zone 'linux.xxxx/IN': adding an RR at 'MMMM-LENOVO.linux.xxxx' TXT Mar 23 21:24:39 ubuntu-gateway dhcpd: DHCPREQUEST for 192.168.10.119 (192.168.10.22) from 44:85:00:4d:49:37 (MMMM-LENOVO) via eth0 Mar 23 21:24:39 ubuntu-gateway dhcpd: DHCPACK on 192.168.10.119 to 44:85:00:4d:49:37 (MMMM-LENOVO) via eth0 Mar 23 21:24:39 ubuntu-gateway dhcpd: Added new forward map from MMMM-LENOVO.linux.mxxxx to 192.168.10.119 Mar 23 21:24:39 ubuntu-gateway named: client 192.168.10.22#56110/key rndc-key: signer "rndc-key" approved Mar 23 21:24:39 ubuntu-gateway named: client 192.168.10.22#56110/key rndc-key: updating zone '10.168.192.in-addr.arpa/IN': deleting rrset at '188.8.131.52.10.168.192.in-addr.arpa' PTR Mar 23 21:24:39 ubuntu-gateway named: client 192.168.10.22#56110/key rndc-key: updating zone '10.168.192.in-addr.arpa/IN': adding an RR at '184.108.40.206.10.168.192.in-addr.arpa' PTR Mar 23 21:24:39 ubuntu-gateway dhcpd: Added reverse map from 220.127.116.11.10.168.192.in-addr.arpa. to MMMM-LENOVO.linux.mxxxx
However, when checking the actual zone files, I don't see the records, though dns operations do seem to work. I see that it creates the .jnl files and I assume that is where the DNS is getting its info from?
After researching, I see that I can basically write the jnl info into the zone files by the freeze, reload, thaw method on rndc.
That being said, how should this whole process work?
Is the jnl file where I should keep my entries?
What is the difference in leaving them here and writing them to the zone file?
If a lease expires and no longer needs to be in DNS, will the freeze, reload, thaw process clear it out of the DNS zone file?
Does this DDNS update no happen automatically? Thus, if not, do I need to set up a chron for the freeze, reload, thaw every so often? If so, recommendations on how often?

Leap is a solid performer. I had no trouble installing it on MBR and EFI systems. Secure Boot tends to be buggy with some configurations, but it was incident-free with this installation.
The bootloader handles multiboot with other Linux distributions or Windows fairly trouble-free. Installation is routine, thanks to the graphical format used.
Only 64-bit versions are available for x86 computers, which limits access to legacy hardware in the 32-bit machines. ARM ports are available if you can track them down through the project's wiki.
Plugg.ee Labs’s Cortex-M3 based “JuicyBoard” robotics kit is designed for building stepper motor controlled devices like 3D printers or CNC routers.
The JuicyBoard has surpassed its modest funding goals on Crowd Supply, providing a modular, open source development kit for stepper motor oriented devices such as 3D printers and CNC routers. Built around an NXP LPC1769 Cortex-M3 MCU, the kits are available starting at $179, with shipments due June 15.
Reddit: My graphic design buddy is looking to make some new logos for any and all open source projects!
My friend is wanting to create a few logos for open source projects as a donation of sorts. His styling is modern and slick and best part is: no strings attached!
If you are interested in getting a logo for your open source project, PM me and link me to your project and we can make you one. :)

Are Low-Code Platforms a Good Fit for Feds?
Open-source code platforms — in part, because they’re often free — have long been a popular choice for digital service creation and maintenance.
In recent years, however, some agencies have turned to low-code solutions for intuitive visual features such as drag-and-drop design functionality. As Forrester Research notes, low-code platforms are "application platforms that accelerate app delivery by dramatically reducing the amount of hand-coding required."
Crunchy Data Brings Enterprise Open Source POSTGRESQL To U.S. Government With New DISA Security Technical Implementation Guide
Crunchy Data — a leading provider of trusted open source PostgreSQL and enterprise PostgreSQL technology, support and training — is pleased to announce the publication of a PostgreSQL Security Technical Implementation Guide (STIG) by the U.S. Department of Defense (DoD), making PostgreSQL the first open source database with a STIG. Crunchy Data collaborated with the Defense Information Systems Agency (DISA) to evaluate open source PostgreSQL against the DoD's security requirements and developed the guide to define how open source PostgreSQL can be deployed and configured to meet security requirements for government systems.
Democratizing IoT design with open source development boards and communities
The Internet of Things (IoT) is at the heart of what the World Economic Forum has identified as the Fourth Industrial Revolution, an economic, technical, and cultural transformation that combines the physical, digital, and biological worlds. It is driven by such technologies as ubiquitous connectivity, big data, analytics and the cloud.
Meteo-Qt – An Elegant Weather App for Linux Desktops
Meteo-qt is a Python 3 and Qt 5-based application for Linux desktops that displays weather information in desktop panels and desktop notifications, and a 6-day weather forecast in its own window.
Chemistry on the Desktop
For this article, I thought I'd introduce another chemistry application—specifically, BKChem, a free chemical drawing program. As opposed to many other chemistry applications, BKChem provides both a nice GUI for constructing molecules and a set of chemical analysis tools to look at the properties of the newly constructed molecule.

Devops embraces security measures to build safer software
Devops isn’t simply transforming how developers and operations work together to deliver better software faster, it is also changing how developers view application security. A recent survey from software automation and security company Sonatype found that devops teams are increasingly adopting security automation to create better and safer software.
This Xfce Bug Is Wrecking Users’ Monitors
The Xfce desktop environment for Linux may be fast and flexible — but it’s currently affected by a very serious flaw.
Users of this lightweight alternative to GNOME and KDE have reported that the choice of default wallpaper in Xfce is causing damaging to laptop displays and LCD monitors.
And there’s damning photographic evidence to back the claims up.
