Last month I mentioned that to help me develop further as a programmer and to be motivated that I would be working on a new project every month.
In October I decided to create a Crossword creation script that has now been completed (with some bugs still so still stuff to do). I have posted the outcome on a public BitBucket Repository. Feel free to download and play with the script. I have created some bugs and feature enhancement requests myself so there is stuff to work on.
As many people know it can be very easy to make plans however harder to action them. I seem to be very good at procrastination and less so of removing things from my to do list.
To help me focus and get into the swing of programming I have decided that I need to set myself proper tasks with a set time for completion. To make sure that I carry through I am also going to be posting updates on my blog.
The plan is to start a new project on the 1st of every month, once the end of the month arrives I should have a project that I can then release. This does not necessarily mean the product will be perfect but in a state that I am happy to show others and essentially gives me something to build upon in future. Some of these may remain proof of concepts therefore will never be in a finalised state.
I have now set myself a bucket list, over time I will mark off those that are completed and add new tasks and projects to the list.
For my first month I am working on a simple Crossword Maker. This will not necessarily be something that will result in a finalised project but aims at getting me back into the swing of programming again.
The requirements of this are quite simple. For creating the crossword we have:
User decides on the grid size for the crossword and this is output to the browser
Like many as soon as the Apple music service started I immediately jumped on to the trial.
If you did the same please remember that the trial will end on the 30th of September. I have not utilised the service so it would be a waste to actually continue the service. Continue reading “Cancelling Apple Music”
As developers we can face some difficult choices. Do we make life easier for the user or do we err on the side of security which can detract from the usability of our applications?
Make Use Of recently ran an article that highlights issues caused when usability is given too high a priority over reliability and security.
The article explains that the twitter account of Roger Ebert recently started to post after a long period of quiet. The problem? Roger Ebert died 2 years ago.
Clearly Roger Ebert had not been posting himself. It was thought that his wife had started to post as she retweets using the account at times (why???) but this soon became clear that this was not the case. Make Use Of appears to have come to a good conclusion as to the cause. Roger Elbert appears to have posted Twitter updates using SMS. As Roger no longer has an active phone the number had been recycled and given to another customer in the meantime. As the phone number had been registered for Twitter this remains in place. The new owner can now post as Roger.
Now is this an issue for Twitter or the cellular network. In an ideal world there would be no need to recycle numbers but of course there are a limited number available and inevitably these do have to get reused. Therefore such issues fall upon us as developers (in this case Twitter) to make sure that we consider the failure points of our features and how we can overcome issues.
In Twitters case it would seem that once validated a mobile number can be used with impunity to post with no consideration of this being passed onto someone else. This could easily be overcome. For example for the end-user to have to verify the number on a periodic basis, if an app on the mobile device is also used maybe the app could do this on behalf of the user if they are logged in. This may not stop all occurrences of such issues but will help reduce this greatly. Not only this, but it would give the new owner of the number an easy way to opt out and stop receiving nuisance communications etc.
This issue is not restricted to mobile numbers. 2 years ago Yahoo announced that they would be freeing up dormant email accounts. An account was considered dormant if the user had not logged in to Yahoo for over a set time period. I do not disagree with Yahoo’s decision in doing so however this poses a problem for service providers. Consider the things we do over email. For example if you reset a password on most services you simply require access to the email account in question. This might be easy to use but how secure is it? Also consider some of the private information that we may send over email. Would we or the user be happy if such information was given to other people?
WordPress is currently (and has been for a long time) 1 of the most popular tools for creating blogs and web sites on the internet. Due to the level of popularity that WordPress has gained it has been a target for hackers looking to deface the website, send spam or make the site a part of a bot net (and of course many other things).
The attackers use vulnerabilities that are found in the core code, plugins and yes even themes.
Recently there have been many SSL certificates revocated due to the heartbleed issue. Yesterday, for the first time, I came across a warning advising the information for a certificate was not available. Once reading and accepting the revocation I continued on my merry way.
Today however I received another revocation notice when using the java updater.
Has Java forgotten to remove a revocated certificate from their servers?
Interestingly I had carried out a search simply for sjremetrics.java.com (the certificate was created for this URL) and lo and behold the very first response was for a post on the Oracle Forum which detailed Java having exactly the same issue back in 2010.
Side note. On looking at the details of the SSL certificate I see that it was issues on 17th September 2013 and was due to expire on the 17th November 2014. A 14 month certificate? I did not know that was possible. Or was it revoked in 2013 as well?
I have tried to submit a bug for this issue however Oracle’s bug reporting process is atrocious.
I have received an email stating that the report “will be evaluated”. Don’t think I will bother next time.
Recently I updated the Better WP Security plugin. The developers have decided to rename it to iThemes Security. After a while I kept getting banned from the blog (I just kept getting a page stating “error”.
After doing some digging I found that the problem had been caused by the “default-user-image.png” image that was set in the All In One SEO Pack. I had changed the name of my wp-content folder (as per 1 of the recommendations in iThemes) however the links to this file were still leading to wp-content.
After installing iThemes make sure that you modify the location of the default user image in “All In One SEO” >> “Social Meta”. The setting you are looking for is “Default OG:Image”. Simply change wp-content to the new name that you have given the folder.
On a side note when looking for the issue I came across a red herring. In the main plugin script (all_in_one_seo_pack.php) a couple of constants are defined to state the name of the wp-content folder. When questioning this in the support forum I was advised they are not used any more. Begs the question why are they still there?
