content: This sort of stuff does tend to work at least slightly and to start with. Windows is a dire shitstorm of mess inside from WinSxS to the whole registry mess which everything hooks into and it crawls to a halt. Everything from shell extensions to screwed up COM registrations slowly shaft the entire platform. Most professionals know not to fight the battle and just reinstall the damn thing. I spent enough years fighting it.Unfortunately the usual story is that the company sells a legit cleaner product onto the market, finds they can't compete with the 2 million other products out there doing exactly the same thing, find they have several pissed off VCs on their ass and proceed to ship malware and toolbars with it to break even. Then it joins the slurry of PC fix utilities that people install ten different copies of after googling it and then bring it to me because it's even worse.Genuinely these things start with good intentions but ignorance of the whole state of affairs.

Contacted the seller, he apologized and resend what happened to be again 11/16. Scratching my head, today I went back to the listing and noticed that the picture has a ruler and it is obvious the feet aren't 1/2". Here is the listinghttp://www.ebay.com/itm/122052050336?euid=5e2836ba488742af8d0e3d99741997ab&bu=43194328704&cp=1&sojTags=bu=buwhere you can see what I mean. I have attached a picture with one from each received lot and one from the instrument. You can see there is a big difference.I will contact the seller again, but in the mean time, are there any good sources for rubber feet ?

It's like the current affairs of old, you know, when you used to watch current affairs.Anyway, this particular episode looks at the state of online security from an offensive and defensive perspective with a nod to this years Black Hat. It is a relatively unsensationalised overview for the average Joe, presented to be easily digestable by the general public. If you know a lot about the topic you won't learn anything, but you might know someone who will.I should point out that some content from the ABC is geo-blocked.

content: PV-Installation is actually my main Job and we switched over to Benning or SolarEdge.Mainly because of the quality of the service. SMA has become really picky about warranty things (At least here in Germany). Benning is mostly known for their meters but also makes big industry UPS for Telco and other high reliability stuff. Before we started to install them they invited us to visit their production facility and it looks top notch (Compared to SMA for example). They run a complete 5 hour full load test on the inverters not just individual board test like other manufacturers.SolarEdge is great because of their module based power optimization. You can litterally throw the modules in east south and west direction on the roof connect them up all in series and the inverter makes the best of it. The SolarEdge systems make about 2-4kWh more than other systems per day. They also have a very good online monitoring system which is really esay to set up.This doesn't mean i don't recommend SMA they still make very good inverters this is just a preference i devloped over the past 5 years and when you have to deal with the devicec nearly every day you start to look at other thing like ease of installation,support,weight,featuresHopes this helps and greetings from GermanyDennis

content: I remember reading various reasons why engine oil cannot be used in a HVAC system, from waxes hardening at low temperatures to the oil breaking down over time. (HVAC oils are designed to last the lifetime of the system.) What would make a good assembly lube is Nylog, specifically designed for HVAC systems.Also, the vacuum test is not that effective since it only puts a maximum of 15PSI pressure difference. Compare that to the standard of 150PSI or more using nitrogen or CO2.Nowadays, HVAC compressors are welded metal cans that are simply thrown away if they fail. Which is almost never in a well maintained system.

content: I have never looked into cell phone tracking but right off the bat I would think of just interfacing with the wireless transceiver(s) of the victim's cell phones and using the raw signal to do things like calculate signal strength in order to get an idea if you are getting closer/farther to the source. If you had multiple sensors then you could also triangulate position. In addition, there are likely to be command queries where the search system can ask the cell phone for information such as cell ID, round trip time/ping, and so on that may be useful in helping improve accuracy.As far as Bluetooth, I'm reminded of Apple's iBeacon implementation. I think there were a few crowd-source projects in the past which implemented this to find stuff with phones utilizing tags.

content: Hi guys, I'm almost with EE school and have been proficient in some areas and not so much in others, what I do very well in is VHDL/FPGA programming, although the material that I dealt with was rather basic having taken a required Intro to VHDL class. Interestingly, that is the only VHDL class offered at my university, I guess it hasn't taken a important place in the industry just yet. So, I decided to dial up some course providers namely Doulos which provides courses with a signed certificate and everything from Intermediate VHDL to SoC design. The courses come in series and are in other states which travel and overnight stays are necessary. They cost around 2 grand for 40 hours of courses/instruction which doesn't seem too bad compared to college tuition. It's very fast pace and more set in a boot camp style for coders kind of way. If I take these courses and be out of thousands of dollars, would you think it'd be beneficial for me in the process of landing a VHDL/Digital Logic Engineer or FPGA Engineer Job? let me hear your thoughts and thank you in advance.

It's good you went out and got some more training but what was the level of the training? I don't think 'for pay' schools are highly regarded at the engineering level. My own feeling is that they cater to technicians. I am probably completely wrong!Maybe there's a grand project as part of the training, something you can use for "show and tell". If not, I would think you should create something of significance and bring both the project and the code to the interview. I have no idea what a 'significant' project might be. My choice, were I to do something like this, would be to create a CPU and some peripherals, something for which an operating system might be available, or write a trivial OS like CP/M, and package the whole thing up in a briefcase. Maybe a little 80x25 display with keyboard, perhaps a compact flash for the disk drive, something like that. It probably wouldn't be a Z80 because that has been done. I don't know...At the undergrad level, I wouldn't expect to see more than a semester dedicated to FPGAs and that would probably include both Verilog and VHDL. I doubt that it would include a significant project but maybe...

They lost something like $1.5B that year.The sales people from every major MCU maker spent 2013 and 2014 visiting Renesas's customers, many of whom were eager to find an alternative to the Renesas MCU's they used. Maybe they are getting their act together now, but spending $3B on an acquisition seems a bold move only 3 years later.

I'll do it again.They were originally called Renesas Technology, a joint venture between Hitachi and Mitsubishi, and later merged with NEC Electronics. Supposedly now one of the top 5 in semiconductors.They are probably only interested in really big business, though I think they used to advertise in Nuts and Volts.

timestamp: August 21, 2016, 06:47:14 pm
content: I worry about the long-term safety of a CRT that has had this procedure done.The entire purpose of the bonded faceplate is for implosion protection. Removing the resin layer eliminates this safety feature, even if the glass faceplate is reinstalled over the tube. Before the bonded faceplates were introduced, a separate safety glass panel was used in front of the CRT. The removed and reinstalled faceplate is NOT made from safety glass, and, without the resin bonding layer, offers little more than added shrapnel in the event of a screen implosion.Some vintage TV collectors have had the tube implode while attempting this "cataract surgery", as well.

content: I'd built a couple LED light panels for video work using 10m of LED strips per panel and picked up some relatively cheap buck converters from Drok at Amazon. I'm now working on a smaller LED light to go above my work bench and am using 3 strips of 750mm LED's. I tested the power/current loading with my bench supply and found that when I apply exactly 12VDC to the three strips in parallel the total current was, after giving it time to soak, about 3.07A or about 36.8W.Actually, since there's voltage drop in the wire going to the panel and I'm actually outputing 12.37VDC to get 12.00VDC at the strips the actual power output from the supply is closer to 38W. I then put one of the Drok buck converters in the loop and am using the bench supply to feed it with 19VDC and adjusted the output to be 12.37VDC and the bench supply is reporting 2.09A and 39.7W. The puts the little Drok at nearly 96% -- pretty impressive. I was expecting to maybe need a small 40mm fan to keep the PS cool, but as it's only dissipating about 2W I may not need one. After an hour it's barely warm...I looked at the output with my scope and I see peaks about every 2.2us so that would put the switching speed right at 450KHz.The Drok unit I'm playing with is over spec for this task and I have another smaller one that might just be a tad under spec so maybe I'll give that a look and see how it does.Brian

To be sure these little PS's are not going to have much in the line of input or output filtering but in the LED application that's makes little difference.Brian

I had a small 40mm fan blowing directly on it at 12V and the PS was well over 55C at 2.4A. So, I won't be using that one for the job.Brian
