ARRIS SURFboard SB6141 End Of Life

There is absolutely nothing wrong with my ARRIS SURFboard SB6141, but today after an another Comcast outage in my area, my Blast! 150Mbps internet service came back in a new mode. I was having excruciatingly slow internet speed on Comcast. After a short chat with Comcast representative I figured out that SB6141 does not support their new standard. After checking for a list of currently approved DOCSIS 3.0 cable modems I ordered ARRIS SURFboard SBG6400. For now I hope for easy install and fast speed. Will I be able to plugged right in and would it work perfectly?

SourceTree 2.2 Major Release - DO NOT UPGRADE

SourceTree 2.2 is not stable at all. DO NOT update to the latest version of SourceTree. I guess this release needed a bit more time in the oven. May give GitKraken a proper look now.

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

No Ranging Response received - T3 time-out SOLVED

No Ranging Response received - T3 time-out, I have had this error for the past few weeks looking through the event logs in my Motorola SB6141 and saw this message is popping in the logs several times every day. Apparently this error occurs when the upstream connectivity is lost between my cable modem and the Xfinity Comcast server. Checking my modem signal levels I have found the following data

Downstream Power Level
12 dBmV 13 dBmV 11 dBmV 10 dBmV 10 dBmV 11 dBmV 11 dBmV 12 dBmV

Downstream Signal to Noise Ratio (SNR)
38 dB 37 dB 37 dB 37 dB 37 dB 38 dB 37 dB 38 dB

Upstream Power Level 42 dBmV 43 dBmV 42 dBmV 41 dBmV

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.

Shopify Dashing not updating

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 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 with WEBrick.

To make Dashing working I run this

rackup -p 3030 -s webrick

instead of

dashing start

Motorola SurfBoard SB6141 review

Motorola SurfBoard SB6141 DOCSIS 3.0 Cable modem came to my house as a replacement for Netgear CMD31T modem which was barely working for almost three weeks. Once installed I had a problem with Netgear CMD31T dropping Comcast/Xfinity Internet connection once or more per day. It was not hard to get the connection back, the Netgear modem has easy to understand lights that let me know what is going on with my connection. It usually it takes just a few minutes to get the connection back. but it doesn't work for me. I often work from home and recently dropped my land line phone service replacing it with Ooma Telo Free Home Phone Service. That's why I decided to give a try to Motorola SB6141

Motorola SurfBoard SB6141

The modem was extremely easy to install. Plug in, call Comcast to register, navigate to 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.
