IEEEXtreme: What Did The Penalty Bracket Mean?

The penalty (per challenge), is the time in minutes between the initial release of a challenge and the time at which a team submitted their best answer to that challenge.

For example, the challenge named “Crafting Wooden Tables” was released on the 5th hour of the 14.0 IEEEXtreme competition (05:00 UTC +0).

If a team had their best solution to this challenge submitted at 19:59 (UTC +0), which gives us almost a 15 hour delay, then the penalty for that challenge would be 899 point (14 hours * 60 minutes + 59 minutes = 899 minutes since the release of the challenge.)

Each teams’ total penalty is the sum of all individual penalties.


How to use slack on a mobile device without the application (using a browser)

Recently, we had to use slack to join a workspace but could not use their mobile application for reasons..

When we logged in to the workspace website it would only show us the settings of the workspace and it would prompt us to download the application.

The way we bypassed it was:

  1. to request “Desktop Site” from our browser,
  2. then navigate to the conversation channels and
  3. finally disable the “Desktop Site” mode so that we could get the responsive (mobile friendly) version on our screen!

It is not amazing but it works!

To request the “Desktop Site” from FireFox:

Some websites may appear or function differently from mobile to desktop. Firefox for Android lets you switch between desktop and mobile view:
– Open the page you want to view in Firefox.
– Tap the menu button.
– Toggle the switch next to Desktop site to turn it on and off.

iPhone asking for Passcode before adding one! – Phone locked

While setting up a new iPhone, at the step where you are supposed to type your new Passcode, we let the screen lock. When trying to unlock it it was asking for the Passcode to unlock! Since we never gave it a Passcode that made it impossible to unlock the phone. We tried using the iCloud password with no success..

Please note that we created an iCloud account from the iPhone on the setup process and used a phone number to verify the ownership. When trying to sign in to the iCloud, we got an error that the password is not correct. While trying to recover that password, we’ve verified the password by SMS but we clicked that we do not have the option to used the iCloud account to verify the ownership.

Even though we clicked that we do not have access over the account, it notified us that it will use that account to contact us!!


Why sponsor IEEEXtreme

IEEEXtreme is a global programming competition where IEEE students compete against each other in teams composed of up to 3 people. The competition has an unconventional timespan which lasts 24 hours and it usually starts on a Saturday of October at 00:00 (UTC +0) for everyone around the globe.

During that period the teams are asked to solve algorithmic challenges using their programming language of preference.
The competition platform supports more than 20 different programming languages, including all the popular ones.
This is making it easier for the majority of students to compete as all common programming languages taught at school are covered.

All students are able to join the IEEEXtreme as the challenges set contains challenges of all kinds of difficulty levels.
Up to now there always were challenges that can be solved by junior students and also there were mind boggling challenges for the advanced and experienced students.

Junior students, by joining early they get experience on how to handle the workload with their team members and perform efficient time management based on their skill set.
Participation in more competitions allows them to improve as a team for the years to come and greatly improve their ranking in the future.
We observe that there is retention of contestants as many compete in multiple competitions year after year.

A sponsor may request for a specific challenge to be addressed during the competition and/or set parameters to a challenge.

We hope to get your support in the biggest programming competition of IEEE which is composed of ~10.000 contestants and several hundreds of volunteers around the world!
