A tip for relatively sized Html input elements using `em` units

And why I use Yahoo! (YUI3) Reset CSS Now

For better or worse when doing front end development I prefer to use percentages and em as the unit of size when styling. This approach could be a bit tricky but with proper experience and the use of css screen size conditionals does allow for one rendering base for multiple screen sizes.

As base I set px font-size only on the <body> html element and then afterwards use em to style all other elements; of course using pixel based units where it makes sense. This allows for example the quick changing of the font-size just on the body tag and having all the header resize accordingly.

One annoyance that I experienced was that input radio and check buttons didn't honour the font-size of the body and I always just worked around the issue by explicitly styling the input radio or checkbox buttons height to a em value that made it look good.

However, today by pure accident I discovered that adding font-size: inherit to the input styling fixed the problem: the height of the element is the font-size of the body element which equates to a proper effective 1em.

This to me is something that should be in a reset style, but the Eric Meyer's reset style sheet at meyerweb.com that I have been using for years dosen't have it. After reviewing all the other options at CSS Reset site the only one that addressed this issue is the Yahoo! YUI 3 Reset Sheet – and so with confidence that is the one I use now.

Duplicate value found: duplicates value on record with id: <unknown>.

System.DmlException: Insert failed. First exception on row 0; first error: DUPLICATE_VALUE, duplicate value found: <unknown> duplicates value on record with id: <unknown>. The above error is triggered in the database layer and caused by a trigger or workflow outside of your main code of block that is bubbling this exception. This is rather difficult to track down especially if you are unfamiliar with the code, I am sharing my procedure in the hopes this saves you time - if you find this helpful drop me a line or follow me on twitter @danielsokolows . This error is caused by unique field constraint on the object, so the first step is to examine the object and locate the API names of all unique fieds. You can do this through SF direclty 'Setup < Customize &lt <object being inserted> &lt Fields' or by downloading the `src/objects` metadata information and searching for <unique> ; I preffer the latter and actually download ALL matadata i...

Softeher 'Error occurred. (Error code: 2)' sollution

Protocol error occurred. Error was returned from the destination server. The Softether server by default to run on port 443 , if you server also hosts normal https then 443 is already taken and so Softether can't bind to it. When you run `vpncmd` it attempts to connect, find an active port, but of course fails with 'Protocol error occurred. Error was returned from the destination server.' because it's not actually connecting to the vpn server. By default Softether also listens on 992 , 1194 , and 5555 so the sollution is to modify specify `localhost:5555` when executing the `vpncmnd`. If this has helped you feel free to comment or follow me on twitter @danielsokolows .

How to child proof a fireplace

DIY - Do it yourself fireplace child guard Our wonderful 8.5 month old Sofia has become a crawling race car with an untamed thirst for exploration. And so with the cold nights approaching we needed to child proof the fireplace. This however proved to be more difficult than would reasonably expect, I've checked the local Toys "R" Us, Walmart, and even a Canadian Tire with no success for a ready to use product. Internet search was more fruitful and returned a few online stores one could order from, however in all honestly they didn't look too sturdy to me. So I build my own relatively quickly and inexpensively. Materials needed is a privacy plastic lattice - the smallest hole pattern - a few screws and anchors; tools needed are a drill, and a handsaw if you don't have the lattice cut at the store - that’s it. The construction consits of screwing the lattice into the wall and the final product is easiest explained through following pictures. ...
