Atlassian really needs to work on its validation practices. The last few HipChat client updates have been disasters as well.
Downstream Power Level

The downstream power is on the high side, and -7dBmV to +7dBmV is the ideal range for cable modem, so I have found 2 way signal splitter and added to the the line leading to the modem hoping that extra attenuation will knock that power down. And it worked, the downstream power level went down. For the last few days my Xfinity Comcast connection works like a charm and there is no No Ranging Response received - T3 time-out in the log files.
I have started to work on dashboard for my team to display Pingdom, Jenkins and Jira metrics using Dashing by Shopify that could suite the Agile team needs. The initial setup on Apple MacBook Pro was a breeze, but I was able to see on localhost:3030/sample page the layout I expect, but none of the widgets have any data. I waited a a few minutes and eventually hit Ctrl+c to shutdown Dashing, and magically the data were updated and displayed. I tried Firefox on the same machine, but got the same result - nothing changes on the website, no data is shown just the headings. Same thing is happening to the dashingdemo.herokuapp.com/sample demo page set up by Shopify. The Chrome Developer Tools shows the /events resource as "pending" and it seems to hang on this indefinitely without receiving any data. Surprisingly the demo page worked fine on Windows 7 machine with Google Chrome 35.0.1916.153, but Google Chrome and Firefox on Mac displayed no data.
After digging around I have found that the issue is with a Ruby web server - Thin. As soon as I tried another web server WEBrick instead of Thin everything started to work on my Apple MacBook Pro, but of course I’m not able to restart hanging dashingdemo.herokuapp.com/sample with WEBrick.To make Dashing working I run this
rackup -p 3030 -s webrick
The modem was extremely easy to install. Plug in, call Comcast to register, navigate to www.comcast.com and you are good to go in the less than 15 minutes. Once I upgraded to Motorola SB6141 I couldn't believe it, it works like a charm for almost a month now. The only downside to this modem are those damn blue LED light. I taped over them with black electrical tape, but because the device is covered with ventilation holes, the LEDs blare through them. I would recommend installing the modem outside your my peripheral view.
