At my day job, I’ve been doing some Android development. Due to the nature of the application, we’d like to connect the device to larger screens both directly using HDMI and by streaming through a DLNA client/server connection.

Anyway, I ordered a 10 foot HDMI cable off Amazon last week and it arrived today. After connecting the Android tablet to the TV and pressing “play”, I was happy to see the same thing displayed on the tablet show up on the 37 inch HDTV here. Pretty sweet …. until ….

This article is just for me to recall how to print envelopes.

Using LibreOffice, use the Insert —> Envelope menu.

• Addressee is the TO field.
• Set the paper to landscape.
• look at the print preview – move the location box as needed.
• Use the front feed for the Samsung printer.
• Insert the envelope with the print-side up with the normal fold opening from the center and down to the left of the printer. You will read the envelope from the right-hand side of the printer looking left.

If this helps someone else, I’d be shocked. OTOH, I don’t use paper envelopes very often, so having this written down somewhere means fewer throw way envelopes due to failed printing attempts.

This morning I saw an email from a business associate. It contained a link to an article on LinkedIn. That article was actually hosted on mashup. The article was about Social Media Overload; he called it The Sharepocalypse. After reading a fairly long article pointing out all the issues with the different human interactions with the main social media providers, I wanted to add a comment. Oddly, I couldn’t unless I used either a twitter or facebook account to login.

Yesterday, I was told that there was some issue with email here. Messages were bouncing. After a little research, it was determined that the ISP had decided to filter port 25 inbound AND outbound. That began around 1:50am on Wednesday morning. I know this because there are logs. Why did they change this after 12 years? I’ll never know.

About a month ago, an editor at a large blog website followed one of my links in a comment there back here and offered to republish the story. I was already seeing increased traffic from that link on their site – like 10x more than my normal daily traffic – and it scared me. I don’t have the bandwidth to handle that sort of traffic and my Ruby on Rails blog software … er … pretty much sucks from a scalability perspective. What did I do?

Today I was notified by my DNS provider that someone had requested the password be reset. They sent the reset link in the email on file and told me the IP address of the requester – in this case it was from Taipei, Taiwan 112. Good thing the DNS guys have a correct email address for me, huh? I suspect they hacked the ISP email address which I haven’t used in about … 10 years. Sometimes you get lucky. DNS – Domain Name Service is the telephone book of the internet. Learn more about DNS from Wikipedia.

• I won’t be resetting that password anytime soon. It is fairly long and random.
• I will be blocking all access to this blog from that ISP, however.

Subnet Blocked

Enough said?

Almost everyone likes Facebook and Twitter. We reconnect with our friends, they connect with us. People we don’t even know want to know us – that’s pretty cool, until it isn’t.

This will be old news for some folks. Keep reading … Here’s a story about someone named Wigginbottom who tweeted just a few too many details.

Below is the email that we just received concerning the long promised Silicon Dust HD HomeRun Prime Networked QAM cable recorder with CableCARD decryption. It supports Multistream-CableCARDs (m-cards).

It appears this device will only with with Windows7 Media Center due to DRM requirements for CableCARD compatibility. That could be an issue for many Linux users.

Questions

There are a few questions that this email doesn’t answer:

1. Will the CableCARD decryption work with MythTV, GB-PVR, BeyondTV, SnapStream and other non-MS-Windows Media Center solutions?
2. Linux systems supported?
3. Can recordings be archived for playback by non-DRM devices?

Network Upgrade May Be Needed

The tuner does have GigE networking (1000 base-tx), which is needed to stream 3 full HD programs. If you get this device, you’ll need a GigE switch and may need a GigE router to avoid dropped packets on your network. The good news is that GigE switches are $20 and work just fine. Many WiFi routers that support 802.11n include GigE switches, but you’ll want to check yours, since 50% are still only 100base-t. Older wifi routers with 802.11g are are almost always 100base-t. If you don’t know networking, just get a GigE router and it will be easier. No switch needed.

Pricing

3 Tuner Model

I just looked at Newegg and the HDHR3-CC (3 tuner model) is $250 + $7 shipping. It also lists only Windows7 as the supported OS. No others.

6 Tuner Model

NewEgg doesn’t have a page for the 6-tuner model mentioned in the email above.

It seems just like yesterday when the Space Shuttle Endeavour had her first mission in space. That was 1992. Those of you who know me, know that I worked as a NASA contractor from ’89 – ’96 writing GN&C software for the space shuttle fleet, writing applications for the mission control centers around the world and laptops used onboard the shuttles and space station. Thousands of other people have similar, if not closer, connections to Endeavour.

Endeavour was the first shuttle to fly with an upgraded nose-wheel steering. This is particularly personal for me, having spent about 9 months implementing the software to take advantage of those upgrades. Many thousands of lines of code and some Karnaugh mapping to speed the boolean decisions. Many thanks to Henry for pointing this dumb ASE to that logic simplification technique. I recall during the code review at IBM-FS that nobody had checked those lines of code for 100% accuracy due to the complexity. They announced it. A peer on my team had validated it by creating exactly the same equation himself (thanks BW!) and we tested every possible combination of inputs to validate we met requirements 100%. It passed. Running that many tests was a major team effort with all the other coders jumping in to save me from missing the deadline for weeks. I doubt anyone has touched that code ever since.

I have fond memories of walking around building 30, working on the FCR computers, servers and working with the different flight controllers. This week, I found myself re-watching the HBO From the Earth to the Moon series. It brought back more memories even if some of the places aren’t 100% accurate. I also recall watching the Apollo 13 movie on opening day, surrounded by NASA flight controllers at a local movie theater on NASA Rd 1 in Webster, Tx. Yes, we saw it during work hours. Together, we changed the world for the better.

Anyway, Godspeed Endeavour. Here’s wishing that you only exercise the nose-wheel steering and elevon flight control code that I implemented for smooth landings and none of the other code – mostly for when really bad things are happening.

The launch is scheduled for around 3:47 pm today. I always hold my breath (not really) during a launch. Going into space is a dangerous business the way we currently do it.
