Re: Anyone repair anything today?

Had the dryer vent freeze closed yesterday late afternoon. Problem is we have an upstairs laundry so that means borrowing the neighbour's 20ft ladder, setting it up in the middle of a snow bank down the side of our house, on quite a slope where I need blocks of wood under it to keep it level. Of cou...

Re: Winter weather

Seeing as it was too cold to ski we went in the hotel pool, then we noticed the outdoor hot tub. Ended up with totally crazy frozen hair.

Getting out and putting the cover back on was painful.

Re: Winter weather

At a ski resort for a wedding. Sitting here watching the empty chair lifts going up the hill and almost nobody skiing. It's -23C and with the windchill -28C. It's actually too cold for Canadians

Re: Recommend a Chromebook

I ended up going with the Asus I linked above. It does have an SD card slot, and while I agree that the CPU looks anaemic on paper, it is responsive enough and does wonders for the battery life.

Re: Anyone repair anything today?

Had an issue with the gas fireplace, the pilot was fine but when we turned on the main burner then sometimes that would drop out every now and then. The fireplace is one with a remote switch on the wall that's driven by a thermopile so it still works if the power is out. I was worried that the therm...

Recommend a Chromebook

This is for my son who is in grade 8. All the school work these days seems to be on Google Classroom and they have a mad rush for those without laptops to grab the chromebooks at school. He's got access to the desktop PC in the family area at home, so I want to go with a Chromebook rather than a mor...

Re: Cisco ASA keeps killing my SSH connections

I still have my money on a TCP window scaling issue as JBI and I suggested back in July. Broken setup is on a redundant pair of ASA's. If the TCP flow switches from one to the other then the window scale factor gets lost and now the packets are being sent outside the TCP window as far as the ASA and...

Re: Best wireless printer

The answer used to be an HP small business laser, the old Laserjet 4si being a notorious tank of a printer (although from the days before wifi!). These days I'm not so sure about HP, but no matter which company I would tend to look at the small business offerings rather than the home stuff.

Re: GCC errors with compiling C code.

It's best if you do just to help in avoiding doing something boneheaded, but I think Buub was referring more to the kind of "micro-optimizations" that may shave a some CPU time off the program, but do so at the expense of readability. Yes, this too. Make the code correct, first, then opti...

In fact my car will actually charge at 175A - just that there are no 100kW CHA...

Executive retention bonuses. If they wind up the company now then the poor execs don't get lots of fat retention bonuses and the workforce may still have money in the benefits pot. See Sears Canada for reference.

Re: GCC errors with compiling C code.

It's also really surprising that no matter how many hours you have spent staring at a bit of code trying to work out where the bug is, if you start explaining it to someone else the bug often becomes obvious.

vi isn't a "What You See Is What You Get" (WSYWIG) editor, it's more like "You Get What You Asked For, Even When You Didn't Mean It!"
