What differentiates HPR from other podcasts is that the shows are crowd sourced from the community - fellow listeners like you. There is no restriction on how long the show can be, nor on the topic you can cover as long as they are not spam and "are of interest to Hackers". If you want to see what topics have been covered so far just have a look at our Archive. We also allow for a series of shows so that hosts can go into more detail on a topic.
You can download/listen to the shows here or you can subscribe to the show in your favorite podcatching client to automatically get our new shows as soon as they are available. You can copy and redistribute the shows for free provided you adhere to the Creative Commons Attribution
Hacker Public Radio (HPR) is an Internet Radio show (podcast) that releases shows every weekday Monday through Friday. HPR has a long lineage going back to Radio FreeK America, Binary Revolution Radio & Infonomicon, and it is a direct continuation of Twatech radio. Please listen to StankDawg's "Introduction to HPR" for more information.
Hacker Public Radio is dedicated to sharing knowledge. We do not accept donations so please consider supporting our patrons. If you listen to HPR, then we would love you to contribute one show a year. Our shows are by default released under a Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) license. All the software we use is Free software. All the code we develop is published in our gitlab repository. All the media is available via the feeds. We are going through an audit process to release the website code as well.
HPR is entirely community driven. Policy decisions are proposed and discussed on the Mailing list, which is open to anyone to join. Mailing list discussions are brought to the attention of the listening community on the first Monday of the month in the HPR Community News show. This show is also open to anyone to participate in. The schedule for the Community News shows can be downloaded as an iCal calendar containing recording dates for the next 12 months. A reminder is also sent to the mailing list in the week before the recording.
Our hosting is kindly provided to us by Josh Knapp from AnHonestHost.com, and he has the last word in issues related to site security. A changing team of volunteers called the "admins" or "Janitors", deal with the day to day operation of HPR. Acting as the first point of contact, processing the shows, coordinating policy discussions, removing spam, updating the website, etc. They are contactable via the email account admin @ HPR. They have no more say over policy than anyone else. Anyone who has shown a long term dedication to the project and is trusted by the community, can become an admin.
See the section stuff you need to know for more information.

We are always looking for more hosts...
HPR is governed by the community, so decisions about how Public Radio should be run are made on the mailing list you can join it by going to :
Well you've come to the right place. Our goal here at HPR is to make it as easy as possible for you to get a podcast released. We take care of the hard bits so you don't need to. Recording your first show is always a daunting prospect but over people like yourself have done it and so can you.
The first thing you will need to do is decide on a topic for your show. You might already have an idea but if not you can have a look at our Archive page for examples of shows people have recorded in the past. You can also look at our Requested Topics, or our Series page to see if you can add your knowledge to the pool.
If you are worried that your show may not be of interest to then you can click here to check if it is.
If you can't think of anything to talk about then please just record a show telling us how you got into tech as a way to introducing yourself to the community.
Please select more detailed information on how to record a show:
Don't forget to introduce yourself in your show.
Once you have your audio ready you can post your show by going to the Calendar page or press the ⇧Upload⇧ button.
After you have selected a date you will be redirected to the request page, where you will be asked to select your show and email address. We will send a link to where you can upload your show to this address and so it must be a valid working address that you can access quickly. We intend to use GPG to speed up the validation of hosts, so you may wish to use an email address that has an associated public key available on public key servers.
Got any questions not covered here, then just email "admin" at "", and we’ll get in touch with you with all you need to know about getting your show published.
You can chat with other podcasters using IRC in the #oggcastplanet channel on the freenode.net network. Follow us on identi.ca (use the tag !hpr) and on Twitter (use the tag #hpr). We have a Facebook and LinkedIn group, so please join and spread the word.
Fellow listeners like yourself contribute the shows and so we all know how hard it is to do that first show. You're probably worried that we won't like the topic. Well don't be, have a look at our archive to see how diverse the contributions have been. You're probably worried about the quality of your audio, that you sound funny, that English isn't your native language, that you suffer from a speech impediment, that your show has loads of ummms and awws in it, well don't be. We have plenty of hosts that fall into all these categories but continue to produce great shows.
At the end of the day the show is about the content and not the quality of the audio. That's not to say we won't help you with ways to improve the audio if you wish, or narrate your script if you can't or won't record it yourself. Drop into the IRC channel #oggcastplanet where there are people who will help.
Any audio is better than no audio.
Any topic of intrest to hackers.
It ain't a show unless it's on the server.
If you tell us you are doing a show, then you owe us a show.
You don't need anyones permission to upload a show, but if you have any questions then drop into the #oggcastplanet channel on freenode and chat with a live person 24/7.
This is a list of topics that have been requested by the community. Feel free to add it to the list by emailing admin at hpr or by tweeting us on @HPR.
This is some important information that you will need to know before uploading to HPR.
Once you upload a show, you will no longer be allowed to edit pages relating to Hacker Public Radio in Wikipedia.
The community decides the HPR policies. Please join the HPR Mailing List to participate.
Hacker Public Radio is dedicated to sharing knowledge. We release about 260 shows a year, which is probably more than all of the other FOSS podcasts put together. If you listen to HPR, then we would love you to contribute one show a year. Remember once that all the reserve shows have been used up and there are no more shows in the queue, HPR as a project will stop.
Our hosting is kindly provided to us by Josh Knapp from AnHonestHost.com, and The Internet Archive at Archive.org. We encourage you to support our Patrons. Over the years kind people have donated services and supported equipment for our conferences.
HPR is founded on the principle of Hackers sharing knowledge. For this reason we are only releasing material created exclusively for HPR. We will continue to promote new podcasts and other creative commons material, but if you wish to have your show promoted, then please contact our sister site Free Culture Podcasts.
That said, if there is a piece of creative commons content that you would like to promote, then feel free to record a regular show. There you can introduce the content and explain why it is important, providing links to where we can get more information etc., and then include one example episode.
All our shows are now released under a Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) license, which means that while you continue to retain the copyright to your show, you are allowing us (and everyone else) to use it provided we give you attribution and that we release it under the same license. Click the link for more information.
Never include content, for example music, in your show that you do not have permission to redistribute. Try to avoid using any content in your show that can not be redistributed under a Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) license. If you are redistributing under another Creative Commons license, GNU Free Documentation License, public domain, or FLOSS software license, then please signal that when you upload your show. We do not post other copyrighted content, even if it is made available under fair use, or by arranged permission.
We do not vet, edit, moderate or in any way censor any of the audio you submit, we trust you to do that.
Aside from checking snippets for audio quality/spam checking, we have a policy that we don't listen to the shows before they are aired.
This is a long standing tradition arising from the fact that HPR is a community of peers who believe that any host has as much right to submit shows as any other.
We do transcode the audio into different formats.
Please note that this only relates to the audio you upload. The rest of the meta-data (branding/summaries/tags/show notes/etc.), are managed by the HPR Community, and may be edited. The show hpr2210 :: On Freedom of Speech and Censorship describes the agreed approach to this topic.
Given that we are an open forum for free speech we signal all our shows as "explicit" with the assumption that the listeners will apply the required discretion when playing the shows in public. That said the majority of our content is technical in nature and therefore is often considered appropriate for any audience. If you feel that your show will be considered inoffensive in every region of the world then you can signal that when you upload the show.
When dealing with content that is "explicit" or contains material that would best be suited for a mature audience, it has become traditional to include a short warning at the very beginning of the show before the intro, to allow listeners time to switch off the episode should they so desire.
hpr2210 :: On Freedom of Speech and Censorship describes the agreed approach to this topic.
The HPR Schedule is entirely community driven and we recommend that you pick the date or show number as then you know when your show will be released. However the slots will only be allocated once the shows have been successfully processed. Any missing information can result in a show missing the requested slot. Once the slots have been allocated it is not possible to move them.
Any host can select any free slot a up to year in advance. However the audio must be ready at time of picking a slot so that it can be upload immediately afterwards.
In exceptional circumstances it may be necessary to reserve a slot while not having the audio available, but this must be approved by the HPR Mailing List in advance. Be sure to allow as much time as possible, and include a reason why you feel it is necessary to reserve the slot.
This is intended only for exceptional circumstances, such as a scheduled interview where we would like the audio to be released as soon after the event as possible, or to cover an important topical situation that has occurred. Due to the extended time now needed to post shows to external sites, the extra work this entails and the disruptive effect of reservations, we will no longer be allowing them except in very rare cases of the type mentioned above.
The following are standing reservations:
See the video "Characters, Symbols and the Unicode Miracle - Computerphile" for an interesting background to ASCII and UTF-8.
When you includes output from the command line in the show notes, posting screen-shots of console or terminal output makes it impossible for screen readers to access the text.
Always try to include the raw output ( eg: embedded in <pre> tags)
Include descriptive language in any link texts.
Avoid structures like: "For accessibility information click here"
Rather use: "For more information click our accessibility page"
We have people listening from all over the world, who may not have the same cultural background as yourself, therefore you should be as clear as possible when giving details. For example always give temperatures in both Celsius and Fahrenheit, measurements in Metric and Imperial, dates in YYYY-MM-DD iso8601 format, and abbreviations using the NATO phonetic alphabet. Never assume that your audience knows what age a sixth grader is, or how big a 20 Cent Euro coin is. Keep in mind that keyboard layouts are also different so make sure to specify the key shape or the position inrelation to a common known standard. For example:
The at sign normally situated above the 2 key on a US keyboard, and has a unicode number of U+0040. For more information see Wikipedia
The reserve queue is intended only to be used in the cases where there is still a gap in the schedule 24 hours prior to release. This was known as the emergency queue, but now can also be used when the hosts don't care when the shows are scheduled. They will be used on a first come first go basis, when there is no conflict with the scheduling guidelines.
On this page you will find information on how to record a podcast. Our golden rule is Any audio is better than no audio. so keep that in mind. Don't forget to introduce yourself in your show.
Many of today's portable media players support recording audio out of the box. Search for "Voice Recorder", to see if there is an application for your smartphone. Whichever option you have close to hand, try and set the recording to the best quality format (WAV or FLAC), and set everything else to the highest setting. It's always the goal to get the best quality audio but here at Public Radio we value content over quality and so long as it's audible we'll take it.
Then just record your show, request a slot, and we'll do the rest.
Some of our hosts recommend Android Audio Recorder on my android phone. It's available on F-Droid and Google Play. These are the recommended settings:
The majority of podcasters use Audacity. First set the Project Rate to 44100Hz, then you can either record your show in Audacity itself or import the file you recorded earlier and edit it as you wish.
Audacity is a free, easy-to-use and multilingual audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems.
When you have finished editing your podcast you can export it.
If you want to record a one-to-one interview with someone then you can use Skype in conjunction with Skype Call Recorder. If everyone is using skype then it won't cost you anything otherwise you will need to pay for SkypeOut service. Although the quality is usually terrible, you could also put your phone on hands free and record with a portable media player.
If you would like to record with multiple participants then you can use Mumble. Connect to chatter.skyehaven.net Port: 64738 .
Walk through the audio wizard and then pop into the Public Radio room. Once you are ready press the recording button, select multichannel and then start. That will record multiple tracks, one for each participant which you can edit and then submit.
Kwisher made a /Mumble-How-To.pdf">Mumble tutorial which you might find useful and Delwin has produced a number of short /correspondents.php?hostid=228">shows on how to configure the audio quality.
You may include backing music but it's best if you don't. Most long time podcast listeners speed up their shows, as this allows them to cram more shows into a day. Having bedding music makes it more difficult to understand, and prevents tools like truncate silence from working correctly.
Others will convert shows to mono to listen in one ear leaving the other free to carry out their other chores. Still more slow the shows down so that they can improve their English. Others are hard of hearing and backing music makes it difficult to understand the text.
We will by default mix down your show to one channel mono and we will transcode to MP3, ogg and spx formats. If you want to control this in more detail then please email admin at Public Radio for more information.
There is no need to add any information to the file as that will be inserted based on the information you fill in when you upload the show.
Feel free to use the promotional material to spread the word in your podcasts, or have them played on to other shows.
Any host can select any free slot a up to year in advance, by recording their show and uploading it to the desired slot. In exceptional circumstances it may be necessary to reserve a slot while not having the audio available, but this must be approved by the HPR mailing list in advance. Be sure to allow as much time as possible, and include a reason why you feel it is necessary to reserve the slot.
This is intended only for exceptional circumstances, such as a scheduled interview where we would like the audio to be released as soon after the event as possible, or to cover an important topical situation that has occurred.

The audio of your show will not be moderated, however the information provided in the upload form may be moderated. All publicly facing material is managed by the HPR Community as a whole, and not just the host providing the show. The show hpr2210 :: On Freedom of Speech and Censorship describes the agreed approach to this topic.
Note: This email address will be published on the HPR website and will be given out in the feeds, so please use a public email address for this purpose. Where we publish it we pad it with dot nospam at-sign nospam dot.
i.e. hpr@example.com becomes hpr.nospam@nospam.example.com. If you do not want to have your email exposed, please contact the admin@hpr team to arrange a alias.
Once you press next, an email will be sent to your email address pointing to where you can upload the show. You need to open the link within 15 minutes or the temporary lock will be released. Once you open the link, you can fill in the information at your leisure. The upload form works on the assumption you will be posting one show at a time, from the same IP address. Once you have pressed submit you will not be able to edit any of the information.
The unique link sent by email will allow you to manage both the episode and information about yourself that is displayed on HPR. The following information will be requested:

Hacker Public Radio (HPR) is an Internet Radio show (podcast) that releases shows (episodes) every weekday Monday through Friday.
What differentiates HPR from other podcasts is that the shows are crowd sourced from the community — fellow listeners like you. There is no restriction on how long shows can be, nor on the topic you can cover, as long as they are not spam and "are of interest to Hackers".
If you want to see what topics have been covered so far just have a look at our Archive. We also allow for shows to be grouped into series so that hosts can go into more detail on a topic.
Look at the About HPR page for a full description of The HPR Community, Free Culture, Governance and our Patrons.
A question on the mailing list in 2020 asked if HPR is a Content Publication Network like YouTube, or is it a Podcast that random people contribute to? Or to put it another way, is the host addressing the Internet in general or the HPR Audience?
A show is your audio presentation (which we do not moderate), with an intro, outro, a title and a summary.
The audio is the recording you have made and sent in to HPR.
The intro (introduction) is a piece of audio introducing the show. See HPR Theme Music for details. The components are:
The outro is added automatically, but you can add it yourself if you want. It must contain the HPR outro music and the text you will find on the HPR Theme Music page.
Each show needs a title to describe what it is about.
Similarly, a summary helps to add more information describing the show so a potential listener can decide whether to listen to it or not.
Each show is expected to have certain mandatory attributes listed below.
HPR shows are usually expected to be informative or educational, and as such some sort of accompanying written material is highly desirable. This might consist of brief notes, links to relevant web sites, or possibly longer notes and examples. Photographs, diagrams and example files are also welcome if the host feels it helps to get the message across.
Shows are released under a Creative Commons Attribution-ShareAlike 3.0 Unported license. See Stuff you need to know for much more detail about this and related issues.
As a contributor you can choose when your show will be released. We only release one show a day, during week days, but if a slot is free you can claim it. Go to the calendar page to do this. You need to have your show ready to upload before you reserve a slot though.
Strictly, no. Shows are expected to have been made exclusively for HPR.
However, we support promoting new podcasts and other creative commons material. If you record a show of your own in which you introduce the other podcast, perhaps explaining why it is important, and giving links to the feed, you may include an example episode.
A series exists Podcast recommendations, which can be used for such shows.
See Picking a slot for your show for the full details of how to submit a show and what information is required.
A quick summary of the main components is:
We are trying to maintain a collection of tags to allow people to find shows on the same (or similar) topic.
Tags are simple words or short phrases describing aspects of a show such as what topics are covered in it. To get hints about what tags have already been used you can view all the current tags in alphabetical order on this page: Tag summary
Some examples are: android, creative commons and gaming.
Are there any tags that are best avoided?
We don't listen to the audio before posting a show to the website, so we don't change the content.
Unless you have done so and told us you have, we add an introduction to the audio announcing what it is. Similarly we add an outro. This is not editing since we don't change the content.
We may make changes to the show title, summary or tags. Usually these are minor changes such as spelling corrections. The intention is not any sort of censorship, merely to make these items more understandable or easier to index.
Depending on the form the show notes take we may modify these.
We are working on the production of reports about any changes made, which will be sent to the host after we have processed the show.
We may make changes to a show's metadata if the host requests it (see the item on fixing errors after upload).
If a show contains links to resources which disappear after a period of time, we may at some future time change the notes to refer to any Wayback Machine copy that can be found.
It depends on the note format to some extent:
It's very easy to hand-write bad HTML. That's why we use an HTML checker on it, and fix the errors it reports.
A common fault is to write <code><pre>
to define a pre-formatted block of text using a fixed-width font. However it's illegal because the <pre>
tag can't be enclosed in other tags like <code>
. Use <pre><code>
instead.
Spelling is often an issue in notes. As the notes are processed they are edited in the Vim editor with the spell check option turned on. In most cases spelling problems flagged by Vim are corrected.
Grammar and punctuation can also be issues. We do not have very effective grammar checking tools in the note preparation workflow. Modifications may be made to split up extra-long (often comma-spliced) sentences, rationalise the use of capital letters and similar.
The HPR administrators can make changes to show titles, summaries, notes and so forth. Ideally send an email to admin
at hackerpublicradio.org
explaining what the problem is and we'll fix it for you. We'll also ensure that the changes are propagated to the relevant page on archive.org.
Don't be tempted to send in your corrections as a comment. Comments are not propagated to archive.org, so people referring to that copy will not see the changes.
