  • Re: Modern browsers on legacy PC's (Split thread from PSU hall of shame)



    Exactly so! ART is a big improvement, even if a pre-compiled copy of your app takes up more storage. Storage is cheap, CPU is not. ART is still a compromise though. 7.0 looks promising with its re-profiling/recompile gimmick. Gimmick. Lipstick on a pig.

    I would like to see changes to Play Store and the Android presentation layer that allows for native software installs that don't burden the end user with knowing what silicon their device uses. I could provide software that targets...

    Uh huh. Java and JavaScript are two completely different things. Their only commonality is that they're both interpreted (byte compile requires an interpreter - the DVM).

    So, you have byte-compiled Java, and a VM using that to outright interpret JavaScript. That's a guaranteed pig, no testing required. Don't believe me? Write a loop timer in JS that performs enough matrix multiplication to be quantifiable on a given HW device. Measure it accurately, to the microsecond. Write the...

  • Re: Database of UPS inverter output waveforms @ HWI



    Nice!

    I never EVER look at the output of any inverter, unless it bears a Pure Sine Wave claim and I'm running inductive loads, for the same reasons that I don't routinely examine septic tank efficiency. Cuz eww.

    If you're looking for a decent UPS: my UPS is a Xantrex PROsine 2500 with 0/1 cables running through the wall to an outdoor steel cabinet full of Walmart truck batteries. It outputs a sine wave (if it's isolated during measurement) even at its safety trip point of 118VAC 29+...

    Oddly related to OP: If anyone does mobile apps on the side, avoid those 'We Work On Android OR iOS' crap tools like Telerik.

    If you have an app that seems ridiculously slow for what it's supposed to do, it's probably a Telerik or other JS-based app.

    JavaScript has ruined everything. Why do I need to download, then cache, the entire Dojo v2.0.3.2.1.14.64.1 toolkit, just so a web site can display a pie chart of "Major Causes Of Web Performance Issues"?

    Moore's Law is over w/ regard to PC CPUs. A Rizen chip will buy very little noticeable performance over an old rusty 2700K Sandybridge. 50% tops, and that on stuff no one does.

    The biggest bang for buck these days are the PCIe FLASH SSDs. Nothing will work with mechanical drives any more except backups. Why? Because you start your 40K .EXE program, it pulls in 400,000 200MB .DLLs spread all over the disk drive. A mech drive spends the next 30s to 2m seeking and waiting for the...

    Windows performs badly on an i7 and no, it doesn't get better as you subtract hardware.

    I was using a browser on an old i386 box running SCO Unix, X11R5 and Konky last week. It works fine. CNN's JavaScript-overload main page loads in a couple of seconds. I checked Weather.com. It was a pig, but it's a pig on anything. That's a 386. 16MHz. 8MB of RAM.

    Use Firefox. Install NoScript and AdBlock Plus. When a page says "You're Using AdBlock, Please Disable It", just say "Good...

  • Re: Motherboard Gigabyte H110M-S2H

    Or it's overclocked incorrectly, has the wrong multiplier, has the wrong voltage, a missing voltage, spaghetti + marinara on the motherboard, a loose DRAM stick, or a few dozen other possibilities.

    Or, the CPU might be gone. That wouldn't be my first guess though.

  • Re: DIY smart TV or replace tv main board with newer model

    Hang a Roku off your TV. Especially if you aren't electronically and mechanically inclined.

    That said, I stuck a Roku3 and HDMI->VGA converter inside an old Panasonic plasma 50. I added two USB-A jacks, a coax audio jack, and an RJ-45 Ethernet jack, all where the VGA jack used to be. The metal case hosed up wifi reception, so I stuck a pigtail antenna out the vent and taped it.

    Note that WiFi is adequate for most stuff, but MKV movies encoded w/ DTS-MA need Ethernet.

    This bought...

  • Re: Acer 8930g random reboot

    I tested those caps. Yup! Two of them are dodgy. 990K on one of them. Initial ESR is supposed to be 4M ohm.

    This might not be THE problem, but it is definitely A problem.

    For the sake of future folk, I'm going to replace the four 330uf 2.5V caps under the NEC / Tokin 0E907 plastic lid with four Panasonic 2R5TPE330M7 caps. I'll put the NEC / TOKIN cover back on as it likely eases the thermal shock that these caps endure when power is removed.

    Excellent call, guzica. Thanks again.

    Good plan! I'll order some Panasonics. That's a solid 3 days I won't have to stare at this board!

    I'll post back in 3-5 days.

    Thanks!...

  • Acer 8930g random reboot

    32-bit Debian boots, runs great. It'll run for days on Debian.

    Minimal system: mobo has PCIe cards pulled off. Just ssd, ram, keyboard, and display.

    Any other OS, or even 64-bit Debian, starts to boot, then reboots the laptop just as the drivers load. It's not a specific driver that causes the reboot: sometimes one, sometimes another, but it is guaranteed to reboot before all the drivers are loaded. DRAM swap doesn't change it. CPU swap doesn't change it. And, I don't have a donor nVidia board.

    BIOS doesn't provide for disabling SpeedStep.

  • Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

    The IP you think the router has is NOT that IP.

    Find out what IP it [U]does[/U] have, e.g., try command: ‎[B]nmap 192.168.1.0/24[/B]

    This assumes you have a PC with the nmap command, which is not a given in this crazy mixed up world.Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

  • Re: Cap replacement




    I stopped using Digikey. They held up EEVBLOG's Dave Jones' order because his name was flagged by DHS as "suspicious". I understand Digikey's position in that silliness, but the bureaucratic weasels who create such lists will listen to Digikey long before they'll listen to an individual, and Digikey won't push back against anything unless their bottom line takes a hit.

    Feedback signals prevent runaway behaviors. That's true in every system....

  • Re: Electronic/computer repair for profit?

    I won't do the IT stuff (AV/Malware). There's no money in that, and that type of cust is already a proven idiot, possibly an entitled douchenozzle, or worst of all: both.

    MacBook mobos will net you around $300 ea after costs (you charge $325). Your main costs being donor boards, equipment, solder/flux, and the occasional NOS ribbon connector, space, utilities, accounting, etc.

    There's money in phone data recovery. People are always dunking them w/o a backup. They always worsen things by tossing them in rice. That's...

  • Re: Detecting A Bullet

    Tech is not usually the best answer for downrange systems. It's easy to damage anything on the far side of the trigger, so it's best to stick with Cheap/Easy.

    I do what you're talking about frequently, for 5.7x28 practice. I buy the electric yellow day-glow paper, stack it, and cut it to a size that will patch my targets' impact marks. Even a pellet gun hit shows up instantly on that stuff.

    Bonus: I save money by closing up my groups.

    Tech people? Socializing?? With EACH OTHER???

    End times, my friends. End times.

    So, hello from the woods! Yeah, I'm out in the woods fixing motherboards. OK, sometimes fixing motherboards. They're not all fixable, and the hardest part is figuring out which boards to give up on.

    I have one right here that has what I'm pretty sure is a piece of spaghetti, a dab of marinara, and even a splash of wine, all embedded in the ICH9 heat spreader fins. The best part: it doesn't look like the case...
