Again, I reiterate, because this is important! When writing blog articles, it is very important to try to target smaller sized articles. Why? Because with larger articles, the probability that another user coming upon it, but finding that only a sub-portion of the writing is useful is higher. This makes more work for subsequent users who only plan on using small subsets at a time. The solution, of course, is to try to break up your writings into smaller articles from the start. This way, it will be much easier for subsequent users to navigate to only the chunk that they want to use and provide exactly that.

So, the verdict? Extreme adventurers will prefer to also take a paper map and compass with them in addition to a GPS device. Some may even go without a GPS device, but most will not. For sure, non-extreme adventurers will prefer to use a GPS device over a paper map and compass, and they may opt not to carry around a paper map.
So, wondering about the HTML 5 standard and the World Wide Web Consortium (W3C)? Has the W3C since fallen out of favor compared to direct cooperation between Apple, Microsoft, Google, and Mozilla on web standards? Not so. Here’s what happened? For a short period of time, HTML 5 development shifted away from the W3C and toward the Web Hypertext Applications Technology Working Group (WHATWG), but then another shift occurred. The W3C resumed involvement, but under a different initiative than was used by WHATWG: the W3C focused on taking the newer features, and “drawing a line in the sand” to set a specific version of the HTML 5 standard, HTML 5.0. Whereas, in the case of WHATWG, they wanted to continue to evolve a “Living Standard,” without declaring official standard versions. As conditions appear, it seems that WHATWG has since fallen out of favor for the use of “living standards,” where the standard evolves progressively, in favor of more direct cooperation between the leading browser vendors. However, for solidly built and clearly defined standards, the W3C is still the champion in this respect.

Having trouble with HDMI displaying from your Raspberry Pi on your old HDMI TV?
-
The Pi outputs a relatively weak HDMI signal. Some devices may not immediately notice the Pi’s HDMI or may not do the negotiation.
-
Set
hdmi_force_hotplug=1makes sure the Pi believes the monitor/TV is really there. -
config_hdmi_boost=4or higher, up to 9, if your display needs a stronger signal. Alternatively, use a shorter HDMI cable if possible. -
If the display is a computer monitor, use
hdmi_group=1and if it is an older TV, tryhdmi_group=2. -
Do not set
hdmi_safe=1as that overrides many of the previous options. -
Make sure your Pi’s power supply delivers 1A and not 500mA.
-
If you see a problem with the red colour - either absent, or interference - then try a boost. However it might simply be that the display requires a stronger signal than the Pi can give.
-
See the embedded Linux Raspberry Pi troubleshooting guide.
-
Try setting
hdmi_drive=2if you are still having trouble connecting to your TV.

Cannon LCR-5001? DCU? What are those?
Okay, DCU = Diesel Control Unit. Actually it is said to just be the enclosure. So, the actual device inside is just the other part, which the acronym stands for something like load control receiver.
And this is what we’ve found on Wikipedia.

Important! Having problems with clients not getting the latest
version of page updates? Here’s the solution. Make sure your server
is sending the Expires and Cache-Control headers. These will
indicate to the browser that it should send an HTTP request to
revalidate the cache entry when a user accesses the page. If it is
still valid, you still save bandwidth. Otherwise, you guarantee that
the user is seeing a fresh page. You can set this to zero to always
require revalidation every time the user visits the page.

Wondering about garage door torsion springs? The second link in particular is a great resource.
Garage door springs are normally manufactured to last for 10,000 cycles. However, it is possible to have a high cycle count conversion on a stock garage door spring to bring it up to 20,000 cycles. However, it’s important to consider the relative life of the other components, the bearings, the rollers, the track, the cable, the torsion tube, and so on. Also, if your garage does not have a steady foundation, the shifting garage foundation can cause you trouble with those other components going out of alignment and getting damaged at an earlier date. When that happens, excess stress is placed on the garage door torsion spring, effectively reducing its lifetime. Likewise, having an insulated garage to regulate the temperature inside can improve the life of the garage door spring too: great stress can be placed on the spring when used in the cold.
So, one thing to consider is that maybe only the best springs are suited to the best built garages.
Interesting. Atlassian is selling their HipChat and other weird new chat product to Slack. (What was it called? Oh, it was called Stride!) A migration path to Slack will be programmed, and the old systems will be retired. These systems predated Slack, but Slack added more features faster and grew more customers faster.
Slack and Atlassian will make it easy for customers to move, but they won’t be forced to switch, Butterfield said. He expects most will transition, though, adding “single digits” in percentage of market share to Slack.
Important! So, the point in hand here. In the long run, it doesn’t matter how long your product was established and how old it is. It matters how many people adopt it.
Meanwhile, Microsoft is still aggressively trying to play its marketing tactics to keep people from buying Slack. Microsoft Teams, this cheap product that looks like it’s barely written by one person, is still around and boasts a large number of users. It is being given away for free, understandably considering the lack of quality and development effort put forth for it.

Now you’re wondering about smoke detector electrical signaling and communications system. Indeed, the picture is quite a complicated one. Is there a standard? Sort of, BACnet may be the lowest common denominator standard. It is mainly a protocol, with many different choices for the physical media and electrical signaling standard: RS-232, coaxial cable (ARCNET), RS-485, Ethernet, LonTalk (twisted pair, fiber optic, powerlines, etc.), and so on. Still, there are many proprietary protocols in use too, and other semi-standard protocols and wiring styles.
Note that BACnet is also widely used for HVAC control.

Ah, great design here! You can also apply a graphical display system into your fire control panel, no need to rely on weird codes only. The LEDs can be built into the graphics diagram.

Interesting, so RS-485 is like RS-422 but with amendments to switch off receivers, which enables two-wire straight line shared bus topology.

Mylar? Does that contain metal or not?
Now, this is quite an interesting trick going on here. Principally, indeed the material is a plastic, one that is related to polyethlene terphthalate. However, there are “metalized” versions where a thin film metal (aluminum) additive is placed within to provide 99% reflectivity and a shiny metallic effect.
So, the point here is that although there still is metal, it is dramatically less metal that aluminum foil. So, your metal detector might either not detect such materials as metal or only barely detect the metal within them.
