  • The error correction isn’t enough to overcome a bad background?

    My memories of the early days of designing these things for ad clients (we’re talking 2010-11) were that like 20% “damage” was allowed before scanning became difficult. So of course my art director wanted to put cutesy shit all over them to be “unique”.

    I just didn’t want the client to ask when it didn’t work because their phones didn’t like them.







  • I’d love a PAPR system, but I’m mostly just plug welding body panels on project cars once in a while. I spent a little extra on the welding machine (buy once cry once), but it’s still 1/2 the price of a PAPR.

    They look super nice for switching between welding and grinding though. If I was doing it more than a couple hours a week (if that) I’d start saving for one for sure.


  • Yeah, lack of competition is driving a lot of this. Fixing bugs doesn’t increase their stock value. It doesn’t make the line go up.

    Launching products and bragging about profits makes the line go up (especially just before a quarter or monthly report is due).

    AT&T/Bell Telephone was like this for years until they were finally broken up (nominally). When cellphones came out and provided nationwide competition, long distance suddenly became free.

    We need to bust up google, Facebook, etc. They have nothing to push them to be better, just CEO egos and investors to please.








  • Just looked it up and N95-P100 masks/respirators cover most exposure that welding should create. I’m a hobbyist welder, but wear a P100 respirator 95% if the time (100% indoors).

    From NIOSH:

    RESPIRATOR RECOMMENDATIONS

    NIOSH

    Up to 10 mg/m3
    (APF = 10) Any particulate respirator equipped with an N95, R95, or P95 filter (including N95, R95, and P95 filtering facepieces) except quarter-mask respirators. The following filters may also be used: N99, R99, P99, N100, R100, P100. 
    Click here for information on selection of N, R, or P filters.
    (APF = 10) Any supplied-air respirator

    Up to 25 mg/m3
    (APF = 25) Any supplied-air respirator operated in a continuous-flow mode
    (APF = 25) Any powered, air-purifying respirator with a high-efficiency particulate filter.

    Up to 50 mg/m3
    (APF = 50) Any air-purifying, full-facepiece respirator with an N100, R100, or P100 filter.

    (APF = 50) Any supplied-air respirator that has a tight-fitting facepiece and is operated in a continuous-flow mode
    (APF = 50) Any powered, air-purifying respirator with a tight-fitting facepiece and a high-efficiency particulate filter
    (APF = 50) Any self-contained breathing apparatus with a full facepiece
    (APF = 50) Any supplied-air respirator with a full facepiece
