I give you http://pom.ianchanning.com. Pomodoros with a Lock Stock film quote at the end of each one.
I’m a little obsessive about timers (see bottom) and the other pomodoro timers I’ve tried failed on different counts.
I’ve tried to cram everything I find useful about a timer.
Firstly spacebar to start/stop. The timer should be something that sits in the background and requires minimal attention. So a quick ctrl+tab to get the the pomodoro tab and then hit space and then back to your work.
Secondly the timer appears in the title bar and it appears first. Then you can easily see that it’s running so that you can still see the timer when you have lots of tabs open.
Thirdly there’s a start and stop. Possibly this flies against what a Pomodoro timer should do. However any timer I have I want to be able to start/stop/reset. That’s just what a timer should do, it’s annoying if it doesn’t.
Fifthly a count of the pomodoros is useful to know how many you cranked out in the day.
Sixthly, a bit of browser responsiveness goes a long way.
And that’s it. No more please.
Well except I needed to put something in the notification so I jazzed things up with quotes from Lock Stock and Two Smoking Barrels. If you can’t take the ‘c’ word at least once then this timer is not for you.
For those who got this far. I started with the most basic timer I could think of that still had a simple start-stop mechanism. Then after staring at the jquery code I’d copied I realised I could make a generic jquery ticker function. So I can tick 25 minutes down and then tick the pomodoro count up 1 each time. The rest is a codged together front end on top of that.

I’ve been reading into Scrum closer recently and it just seems like a horrible corruption of an inspirational idea, that could much more easily be integrated into normal project practices.
I love the agile principles. I’m repeating them here for my own benefit, I like a good list as much as the next.
- Customer satisfaction by rapid delivery of useful software
- Welcome changing requirements, even late in development
- Working software is delivered frequently (weeks rather than months)
- Working software is the principal measure of progress
- Sustainable development, able to maintain a constant pace
- Close, daily cooperation between business people and developers
- Face-to-face conversation is the best form of communication (co-location)
- Projects are built around motivated individuals, who should be trusted
- Continuous attention to technical excellence and good design
- Simplicity—the art of maximizing the amount of work not done—is essential
- Self-organizing teams
- Regular adaptation to changing circumstances
Each principle makes sense, even if, perhaps, it isn’t attainable.
Their manifesto is harder to figure out, but still has a great aspirational feel to it.
|We value this||Over this|
|Individuals and interactions||Processes and tools|
|Working software||Comprehensive documentation|
|Customer collaboration||Contract negotiation|
|Responding to change||Following a plan|
However importantly note that the second column is still valued, but just not as much as the first.
I realised I’d already got it wrong with what a sprint was – I thought it was two weeks work. They suggest that it should be a month’s worth of work – which makes sense, but why not just call it a month’s worth of work – or if it’s going to be less just call it an increment.
Anyway I read through the Scrum Guide and here’s my unsucked version of their main concepts.
|Scrum Guide™||Unsucked agile guidelines™|
|The Scrum Team||The Team|
|The Product Owner||The Client|
|The Development Team||The Developers|
|The Scrum Master||The Project Manager|
|The Sprint||The Sprint (it isn’t actually that bad a word) / Increment|
|Sprint Review||Sprint Update|
|Sprint Retrospective||Sprint Review|
|Sprint Backlog||Sprint Issues|
|Definition of “Done”||Happy Client|
Can I have a word…
“Shall we go over the Sprint Review later? I’m not convinced that the Product Backlog contains all that we require for the definition of done. The Daily Scrum this morning wasn’t great as the Scrum Master had to get the Development Team to better explain their progress to The Product Owner. We need to make the Sprint Backlog artifact more transparent as The Product Owner feels we haven’t followed what we agreed at the last Sprint Retrospective.”
“Shall we go over the Sprint update later? I’m not convinced that the issues contain all that we require for the client to be happy. The talk this morning wasn’t great as the Project Manager had to get the developers to better explain their progress to the business. We need to simplify the Sprint’s issues as the client feels we haven’t followed what we agreed at the last Sprint review.”
Please let the first type of conversation cease.
New Relic offers completely free server monitoring (CPU, RAM, Network I/O etc) and limited (24 hour retention) PHP application performance monitoring (detailed error logs, PHP vs MySQL load times etc). Its far better than monitoring tools I’ve seen and very useful for trying to figure out any problems with WordPress which can be quite heavy in different areas CPU vs RAM vs Database.
New Relic have excellent docs on the server installation, but this is a summary of the commands, N.B. the
YOUR_LICENCE_KEY needs to be changed:
sudo sh -c 'echo deb http://apt.newrelic.com/debian/ newrelic non-free > /etc/apt/sources.list.d/newrelic.list' wget -O- https://download.newrelic.com/548C16BF.gpg | sudo apt-key add - sudo apt-get update sudo apt-get install newrelic-sysmond nrsysmond-config --set license_key=YOUR_LICENCE_KEY /etc/init.d/newrelic-sysmond start
There’s again useful New Relic installation notes:
sudo sh -c 'echo deb http://apt.newrelic.com/debian/ newrelic non-free > /etc/apt/sources.list.d/newrelic.list' wget -O- https://download.newrelic.com/548C16BF.gpg | sudo apt-key add - sudo apt-get update
This is all repeated from the Server section, so the only actual line required is:
sudo apt-get install newrelic-php5
This asks you to give an Application Name – the best format to use is
[vhost domain];[server domain] where the server domain is used as a kind of parent filter for all vhost domains.
PHP vhosts applications
This doesn’t quite work for Plesk installations as we want a per-directory application performance indicator. This assumes that we’re using the Apache php mod rather than FastCGI as we’re putting PHP ini settings in apache config files.
This guide (http://blogs.reliablepenguin.com/2015/02/11/plesk-new-relic) was the perfect starting point. The application names they suggest are really useful e.g.
[vhost domain];[server domain]
Changing the application name
If you make a mistake with the application name you can change it. Just follow this document (https://docs.newrelic.com/docs/apm/new-relic-apm/maintenance/renaming-applications).
Apache Virtual Hosts
I have a manual setup on a dev server – so I needed to modify the
/etc/php5/conf.d/newrelic.ini file to comment out the appname.
I could then add the variables into the
/etc/apache2/sites-available/* apache config files with
php_value newrelic.appname "vhost.example.com;server.example.com"
WordPress W3 Total Cache
W3 Total Cache offers a basic integration with New Relic through its API.
There’s a couple of links for this:
W3 Total Cache assumes that you’ve setup the PHP application. What is non-obvious is that you need an API key and not your licence key. Via a WordPress SE answer, you can then enable API access (Select (account name) > Account settings > Integrations > Data sharing > API access) and use the generated API key in WordPress Admin > W3 Total Cache > General Settings > Monitoring section (wp-admin/admin.php?page=w3tc_general#monitoring).
In response to a blog post ‘Why I keep fixing my bike‘ about the risks of buying a dodgy second hand bike, I wrote the following comment. It’s something I’m quite passionate about so worth storing on my own blog…
I have bought at least 7 bikes second hand through either ebay or gumtree all without problem. Every bike has been exactly what I was looking for. I wouldn’t buy off an ebay seller with only a small repuatation – and almost all sellers I have seen when searching ebay have 100+ reputation.
I think the chances of getting a lemon are quite small, but you always have to be careful.
With a bicycle you are predominantly paying for a decent frame as the rest can be replaced. Its fairly unlikely that the frame will have been damaged. So buy bikes that have well made frames e.g. Cannondale. I’ve purchased a Specialized, Cannondale, Merkx, Orange, Klein and Marin bikes. Most of the bikes I bought would have had a new value in excess of $1000. I’d be most wary of buying a Specialized bike as they are the most common and the current Specialized bikes I’ve seen have very poor welding on the frames.
Certainly don’t go buying cheap branded bikes new bikes e.g. and shop’s own brand. If you’ve got very little money you can pick up old retro racing bikes for less than $100.
Limit your search to only bikes that are near buy (i.e. 30 minute drive) so that you don’t waste much time.
There are many things you can look for:
- Has the bike been stored inside – if you see a photo of it hanging up in a garage on its own rack its a pretty good bet that it has
- Buy ‘fixed’ bikes without suspension as the suspension can be expensive to replace
- Look at the type of gears that it has
- Check how detailed the spec of the bike is – does the person list exactly all the components – this gives an indication of how much the person cares about the bike
- Do they state where they bought it from
- Do they display high quality images of close ups of the gears, the joins of the frame where cracks appear
- What have they been using the bike for
- How often do they clean the bike
- Ask what year the bike is from as well as the exact make and model – then hopefully you can find a reference to how much the bike was when it was new.
- Check the welding on the bike frame – how clean are the welds. You shouldn’t be able to see the welds – as that means it was a cheaply made bike by machines and never finished off.
One of the nice things of Linux is the command history – it stores typically the last 1000 commands or so and its saved every time you log out.
DOS does have this through the
doskey /history command and you can relatively easily append this to a file:
The tricky bit is having this done for you on log out.
This only works for the current session though so you need to create a shortcut that runs the command each time with the following Target:
Then you just have to remember to type
exit each time…
I also found three useful commands – but they’re only for your current session. Hat tip to Nifty Computer Tricks:
- get last command
- current list (use left/right arrow keys to paste to the command line)
- auto-complete (type the first few letters)
Update 2 – Some extra love for the DOS prompt…
If you’ve got this working then I’ve added some extra basics. First you need to install Git (and I suggest you do it using the Chocolatey package). This includes the best versions of gnu commands compiled natively for Windows.
Then download my bang.bat / history.bat gist:
history.bat into the Git bin directory e.g.
C:\Program Files\Git\usr\bin. These assume you are saving the history to
Then you’ll be able to do commands like
history | grep mysql to list all your mysql commands in
history.log with their line numbers. Then call
! 123 to execute the specific line of the
For those stumbling down a similar path…
tldr; Check that your Windows Firewall is turned off.
- OS: Windows 8.1 64-bit laptop
OpenVPN 2.3.4 x86_64-w64-mingw32
My OpenVPN has been working for at least 4 months without problem.
First thing to remind yourself is: When you get the VPN working – copy the OpenVPN log of a successful connection and the
ipconfig /all to file so that you know what to compare when it breaks next time.
- The VPN connection stopped working yesterday 17/10/2014
- Not exactly sure when
- It had been working at my office
- My Windows 7 desktop has a working VPN setup so I can compare the settings
- The OpenVPN gui suggests a connection has been made but no sites can be pinged (see commands below)
- All attempts at
ipconfig /flushdnsnothing worked
- Only differences between Desktop/Laptop I could find in
ipconfig /alland OpenVPN logs was that laptop had IPv6 for the WiFi connection turned off and the following extra fail message
UDPv4: No Route to Hostin the log
- I tried turning IPv6 back on but that didn’t change anything
- Now the UDPv4 message disappeared – but didn’t reappear when I turned off IPv6 again – so that was a red herring
- Possible suggestion from my history when first setting up my VPN (http://www.rickygao.com/troubleshooting-general-failure-in-ping-or-tracert/) was to turn off IPv6 which is what I’d probably done before – but IPv6 is no problem on my Windows 7 desktop
- Pinging even a specific IP address does not work – this confirms its not a DNS issue
- Pinging localhost
- Pinging the IP Address of the connected VPN does work
C:\Users\Ian>tracert google.com Unable to resolve target system name google.com. C:\Users\Ian>ping google.com Ping request could not find host google.com. Please check the name and try again.
Eventually found a solution that was to turn off the windows firewall, which came from this unbuntu forums post which eventually spotted that it was an
iptables firewall issue.
- I thought I’d turned off my firewall and it doesn’t explain why the VPN stopped working
- Best guess is a Windows update changed something in the firewall the caused the problem
- The only Windows updates I received on 17/10/2014 were
- A failed update for
Windows Malicious Software Removal Tool for Windows 8, 8.1 and Windows Server 2012, 2012 R2 x64 Edition - October 2014 (KB890830)– this was successfully installed the next day but didn’t help
- A successful
Definition Update for Windows Defender - KB2267602 (Definition 1.185.3528.0)
