At the lower end of the market, the main competition (Google, Bing, Apple) are totally free. The emphasis on QGIS support suggests that they're hoping to capture "prosumer" and smaller business applications that would get val

That's exactly what this proposal addresses. Consider the paper they cite, in part, for the proposal: "It is a matter of surprise that important documentary records, such as the Fujitsu Known Error Log (KEL), were disclosed only i

If you scroll down to page 3, there is a concrete proposal. The citations for this are worth reading as they expand on the idea, e.g. https://journals.sas.ac.uk/deeslr/article/view/5240/5083 The proposal

I think you're on a reasonable path with your thinking there. Something I learned a couple of years ago is that table saws are particularly popular in the US. It varies from country to country, but in some places circular saws on track

There are quite a few vehicles that do this without an electric door release, for example the Dodge Challenger. I think the whole idea was pioneered by the domestic automakers over a decade ago.

That's the problem though - $0.05 is a LOT to a grocer, that's all they keep on a lot of products. Barcodes are free since they mostly go on labels that are being printed anyway. They could push for source tagging, but the vendor

audio coming right off the TDM phone network will be 8-bit samples, 8 kHz sampling rate, companded. Doing anything else requires direct IP peering (e.g. with a cellular carrier) which is out of reach of your typical inexpensive VoIP trunkin

The cost-per-unit on RFID product tags (EPCs) has tended to limit them to products with a relatively high margin and a relatively high theft potential---clothing being the most obvious example and the most common application of EPCs, with r

I wouldn't characterize the history that way. First, there are multiple reasons that SDI was not pursued, beyond concerns around its feasibility. Most notably, bilateral agreements were signed with the Soviet Union to cease development

The term "fine" seems confusing here. If you look at the form sticker, it seems apparent that £5 is just the on-delivery postage rate for an unpaid item. Different postal services handle this differently, but it's not unusual

Have you been able to perform testing? I think the quality of these Chinese radios has actually improved quite a bit over the years, and the reports I see of testing UV-K5s shows them within FCC limits (well within for 2M, closer to the lim

The locks don't have network connectivity, so they have no way to check. Access has to be managed by key expiry and replacement. There are network-connected systems but they can be considerably more expensive to install.

I don't think the requirement for printed output requires any appeal to military applications. They would have been exchanging navigation information with mission control over the radio. That's all mission critical and needs to be

ATC is used to working with military aircraft without ADSB since it's been the status quo (and keep in mind that ADSB is not required on aircraft in general, although the set of airspace situations in which it's required has been

by jcrawfordor 3y ago
So I'm a little skeptical on that front because military aircraft are still not that often broadcasting ADSB even during routine flights, at least in my (also close to the border) region. In theory the Air Force was supposed to have co

The calculation of a fix from GNSS is actually rather complex and the potential complexity is almost unlimited. The most accurate GNSS fixes are obtained from offline solvers that analyze long-duration (e.g. 24 hour) recordings of the GNSS

Over nine hundred nuclear weapons, many of larger size, were detonated in Nevada from the early 1950s to 1992. The way the article presents that aspect is odd and suggests an author surprisingly unaware of the history of Nevada and the weap

More satellites is mostly better. Multi-constellation receivers for example can obtain higher precision by using some combination of different GNSS. There is a minimum error you can practically achieve this way that has a fair amount to do

This paper is about detecting the connection between the VPN client and the VPN server---the first segment of the connection you describe. It's unsurprising that OpenVPN can be fingerprinted, as like most VPN protocols, it was not desi

There are celestial sources of RF energy but not generally of narrowband signals. The fact that the signal would be described as "unmodulated" is actually one of its interesting features, in that the narrow bandwidth rules out man

They spun out their whole calculator division to a company called Royal. I think Royal is just manufacturing HP designs so hopefully quality held up, but I'm not sure.

It wasn't that uncommon for residential burglar alarms to use polarity reversal on dry leased lines, but it was quite expensive. In a series circuit like this, I'd more likely guess that it was dedicated wiring owned by the alarm

ShotSpotter's own public statements say that audio is retained for 30 hours, see e.g. https://www.soundthinking.com/faqs/shotspotter-privacy-faqs/ . In the past they provided Albuquerque with a document that s

Let me follow up, and maybe I should write this up on CAB but I don't really want to get too much into police reform there, what I know factually about the ShotSpotter system. Most of this comes from discussions with APD leadership and

Hello all, occasionally I write what I consider "Albuquerque content" and I do not expect it to become broadly popular. This article is something I put together very quickly and it probably assumes a certain degree of familiarity

Not at all unique to Japan either, I was confused by the Japan-centric focus of the discussion. I've worked for two different US corporations that observed a company-specific holiday, either founding day or IPO day. It feels to me like

Yeah, magnetic tape is almost as old as the programmable computer, with the UNIVAC notably featuring magnetic tape drives. The main downside was that paper tape could be hand-punched using commodity equipment (often teletypes), while magnet

It's not at all a clean separation, but in early computers, paper tape is more common for loading programs than punched cards. The paper tape readers were faster, and the flexible length made more sense for software before compilers we

Yes, and there has been pretty extensive reporting that based on analysis of the wreckage the balloon was determined to be an ELINT (electronic intelligence) collection platform with a real-time C2 connection using a commercial US ISP (I as

The large balloon was definitely from China, China never denied that. The dispute was over its intention, which China maintains was meteorological research. For example, here is a BBC article that takes a skeptical tone but correctly summar
