Weather Service launches early warning system

Filed under
Sci/Tech

Tornado Alley may sound like a theme-park ride, but in reality, it's the L-shaped strip of land winding from Texas to Minnesota that hosts some of the deadliest twisters in the country.

It's there--and in the midst of what meteorologists predict to be an "extremely active" hurricane season--that the National Weather Service's Dallas-Ft. Worth forecast office on Tuesday will launch a new way of coordinating with widely dispersed emergency personnel.

Let's say that meteorologists detect the signs of a storm brewing. It's weather service practice to give an early heads-up to local first responders and storm-spotting teams before the agency issues a public warning about impending weather dangers. Those few minutes of lead time can give emergency personnel time to get their operations centers in order before a possible deluge of calls and requests from the public.

Since last year, the Dallas-Ft. Worth office had been looking for a way to expedite that prenotification process across its bustling 49-county area, which counts about 7 million residents, according to a press release.

Before, staff at the busy office had been using a wide variety of manual notification methods, ranging from picking up a phone and calling small volunteer fire departments to sending out mass e-mail notifications with no automatic assurance that the messages had been received.

The office decided to implement AlertFind, a system developed by an Austin, Texas-based company called MessageOne, which also specializes in tools for backing up and restoring e-mail in the event of power outages or disasters. It began testing the system several months ago, said Michael Rosenfelt, MessageOne's executive vice president.

  • OpenVZ 7.0 Becomes A Complete Linux Distribution, Based On VzLinux
    OpenVZ, a long-standing Linux virtualization technology and similar to LXC and Solaris Containers, is out with their major 7.0 release. OpenVZ 7.0 has focused on merging the OpenVZ and Virtuozzo code-bases along with replacing their own hypervisor with that of Linux's KVM. Under OpenVZ 7.0, it has become a complete Linux distribution based upon VzLinux.
  • OpenVZ 7.0 released
    I’m pleased to announce the release of OpenVZ 7.0. The new release focuses on merging OpenVZ and Virtuozzo source codebase, replacing our own hypervisor with KVM.
  • Announcing git-cinnabar 0.4.0 beta 2
    Git-cinnabar is a git remote helper to interact with mercurial repositories. It allows to clone, pull and push from/to mercurial remote repositories, using git.
  • FreeIPA Lightweight CA internals
    In the preceding post, I explained the use cases for the FreeIPA lightweight sub-CAs feature, how to manage CAs and use them to issue certificates, and current limitations. In this post I detail some of the internals of how the feature works, including how signing keys are distributed to replicas, and how sub-CA certificate renewal works. I conclude with a brief retrospective on delivering the feature.
  • Lightweight Sub-CAs in FreeIPA 4.4
    Last year FreeIPA 4.2 brought us some great new certificate management features, including custom certificate profiles and user certificates. The upcoming FreeIPA 4.4 release builds upon this groundwork and introduces lightweight sub-CAs, a feature that lets admins to mint new CAs under the main FreeIPA CA and allows certificates for different purposes to be issued in different certificate domains. In this post I will review the use cases and demonstrate the process of creating, managing and issuing certificates from sub-CAs. (A follow-up post will detail some of the mechanisms that operate behind the scenes to make the feature work.)
  • RcppArmadillo 0.7.200.2.0
    The second Armadillo release of the 7.* series came out a few weeks ago: version 7.200.2. And RcppArmadillo version 0.7.200.2.0 is now on CRAN and uploaded to Debian. This followed the usual thorough reverse-dependecy checking of by now over 240 packages using it. For once, I let it simmer a little preparing only a package update via the GitHub repo without preparing a CRAN upload to lower the update frequency a little. Seeing that Conrad has started to release 7.300.0 tarballs, the time for a (final) 7.200.2 upload was now right. Just like the previous, it now requires a recent enough compiler. As g++ is so common, we explicitly test for version 4.6 or newer. So if you happen to be on an older RHEL or CentOS release, you may need to get yourself a more modern compiler. R on Windows is now at 4.9.3 which is decent (yet stable) choice; the 4.8 series of g++ will also do. For reference, the current LTS of Ubuntu is at 5.4.0, and we have g++ 6.1 available in Debian testing.

  • Debian LGBTIQA+
    I have a long overdue blog entry about what happened in recent times. People that follow my tweets did catch some things. Most noteworthy there was the Trans*Inter*Congress in Munich at the start of May. It was an absolute blast. I met so many nice and great people, talked and experienced so many great things there that I'm still having a great motivational push from it every time I think back. It was also the time when I realized that I in fact do have body dysphoria even though I thought I'm fine with my body in general: Being tall is a huge issue for me. Realizing that I have a huge issue (yes, pun intended) with my length was quite relieving, even though it doesn't make it go away. It's something that makes passing and transitioning for me harder. I'm well aware that there are tall women, and that there are dedicated shops for lengthy women, but that's not the only thing that I have trouble with. What bothers me most is what people read into tall people: that they are always someone they can lean on for comfort, that tall people are always considered to be self confident and standing up for themselves (another pun, I know ... my bad).
  • [GSOC] Week 8&9 Report
    This particular week has been tiresome as I did catch a cold ;). I did come back from Cape Town where debconf taking place. My arrival at Montreal was in the middle of the week, so this week is not plenty of news…
  • Debian on Jetson TK1
    I became interested in running Debian on NVIDIA's Tegra platform recently. NVIDIA is doing a great job getting support for Tegra upstream (u-boot, kernel, X.org and other projects). As part of ensuring good Debian support for Tegra, I wanted to install Debian on a Jetson TK1, a development board from NVIDIA based on the Tegra K1 chip (Tegra 124), a 32-bit ARM chip.
