We started producing shows as Today with a Techie on 2005-09-19, 13 years, 2 months, 27 days ago. Our shows are produced by listeners like you and can be on any topic that "are of interest to Hackers". If you listen to HPR then please consider contributing one show a year. If you record your show now it could be released in 20 days.

Meet the team

Please help out tagging older shows !

It’s that time of year again. Time for the Hacker Public Radio 24 hr (26 hr) New years Eve Show. (listen here)

For those who don’t know on New years eve 2018-12-31 10:00 UTC (5:00 am est) we will have a recording going on the HPR mumble server (at ch1.teamspeak.cc on port 64747) for anyone to come on say “Happy new years” and talk about what ever they want.

We will leave the recording going until 1-1-19 12:00 am utc (7:00 am est) or until the conversation stops.

For those who have never used mumble before, we have a guide over at linuxlugcast.com in our how to section explaining how to setup the desktop mumble client, but mumble isn’t only available for the desktop. It is also available for Android and IOS .

We are also going to setup an etherpad for people to share links to things they are discussing.

So please stop in. Say “Hi” and maybe join in the conversation with other HPR listeners and contributors. It’s always a good time.

Duality of the universe: there's true state of the universe used in simulation and there's state the the players perceive. These most likely will always be in conflict. One possible solution is to separate these completely. Perform simulation in one system and record what players see in other.

For every type of entity in the game, there's two sets of data: real and reported. Reports are tied to time and faction. Examples are given for planets. Thus, we have Planet, PlanetReport and CollatedPlanetReport. First is the real entity, second is report of that entity tied in time and faction. Third one is aggregated information a faction has of given entity. In database two first ones are:

Planet json
    name Text
    position Int
    starSystemId StarSystemId
    ownerId FactionId Maybe
    gravity Double
    SystemPosition starSystemId position
    deriving Show

PlanetReport json
    planetId PlanetId
    ownerId  FactionId Maybe
    starSystemId StarSystemId
    name Text Maybe
    position Int Maybe
    gravity Double Maybe
    factionId FactionId
    date Int
    deriving Show

Third one is defined as a datatype:

data CollatedPlanetReport = CollatedPlanetReport
    { cprPlanetId :: Key Planet
    , cprSystemId :: Key StarSystem
    , cprOwnerId  :: Maybe (Key Faction)
    , cprName     :: Maybe Text
    , cprPosition :: Maybe Int
    , cprGravity  :: Maybe Double
    , cprDate     :: Int
    } deriving Show

Data from database need to be transformed before working on it. Usually it's 1:1 mapping, but sometimes it makes sense to enrich it (turning IDs into names for example). For this we use ReportTransform type class:

-- | Class to transform a report stored in db to respective collated report
class ReportTransform a b where
    fromReport :: a -> b

instance ReportTransform PlanetReport CollatedPlanetReport where
    fromReport report =
	CollatedPlanetReport (planetReportPlanetId report)
			     (planetReportStarSystemId report)
			     (planetReportOwnerId report)
			     (planetReportName report)
			     (planetReportPosition report)
			     (planetReportGravity report)
			     (planetReportDate report)

To easily combine bunch of collated reports together, we define instances of semigroup and monoid for collated report data. Semigroup defines an associative binary operation (<>) and monoid defines a zero or empty item (mempty). My explanation about Monoid and Semigroup were a bit rambling, so maybe have a look at https://wiki.haskell.org/Monoid which explains it in detail.

instance Semigroup CollatedPlanetReport where
    (<>) a b = CollatedPlanetReport (cprPlanetId a)
				    (cprSystemId a)
				    (cprOwnerId a <|> cprOwnerId b)
				    (cprName a <|> cprName b)
				    (cprPosition a <|> cprPosition b)
				    (cprGravity a <|> cprGravity b)
				    (max (cprDate a) (cprDate b))

instance Monoid CollatedPlanetReport where
    mempty = CollatedPlanetReport (toSqlKey 0) (toSqlKey 0) Nothing Nothing Nothing Nothing 0

In some cases there might be a list of collated reports that are about different entities of same type (several reports for every planet in solar system). For those cases, we need a way to tell what reports belong together:

-- | Class to indicate if two reports are about same entity
class Grouped a where
    sameGroup :: a -> a -> Bool

instance Grouped PlanetReport where
    sameGroup a b =
	planetReportPlanetId a == planetReportPlanetId b

After this, processing a list of reports for same entity is short amount of very general code:

-- | Combine list of reports and form a single collated report
--   Resulting report will have facts from the possibly partially empty reports
--   If a fact is not present for a given field, Nothing is left there
collateReport :: (Monoid a, ReportTransform b a) => [b] -> a
collateReport reports = mconcat (map fromReport reports)

For reports of multiple entities is bit more complex, as they need to be sorted first, but the code is similarly general:

-- | Combine list of reports and form a list of collated reports
--   Each reported entity is given their own report
collateReports :: (Grouped b, Monoid a, ReportTransform b a) => [b] -> [a]
collateReports [] = []
collateReports s@(x:_) = collateReport itemsOfKind : collateReports restOfItems
    where split = span (sameGroup x) s
	  itemsOfKind = fst split
	  restOfItems = snd split

Final step is to either render reports as HTML or send them as JSON back to client. For JSON case we need one more type class instance (ToJSON) that can be automatically generated. After that handler function can be defined. After authenticating the user and checking that they are member of a faction, reports of specific planet (defined by its primary key) are retrieved from database, collated, turned into JSON and sent back to client:

$(deriveJSON defaultOptions {fieldLabelModifier = drop 3} ''CollatedPlanetReport)

getApiPlanetR :: Key Planet -> Handler Value
getApiPlanetR planetId = do
    (_, _, fId) <- apiRequireFaction
    loadedPlanetReports <- runDB $ selectList [ PlanetReportPlanetId ==. planetId
					      , PlanetReportFactionId ==. fId ] [ Asc PlanetReportDate ]
    let planetReport = collateReport $ map entityVal loadedPlanetReports :: CollatedPlanetReport
    return $ toJSON planetReport

Hi Guys and Girls in HPR land.

This is Tony Hughes in Blackpool in the UK back for another show. I normally talk about my own stuff but while it is related to what I have been doing lately this is a response to Al’s interview with Dave in Episode 2658 and how to setup Audacity to record and edit audio for best sound quality when podcasting.

I’ve recently joined the mintCast podcast team and have been editing and doing the post production of the audio recording for the last couple of episodes. The information that Dave provided during the show was invaluable in helping me in this task, I also have to give a shout out to Rob the previous host who also spent an hour and a half giving a tutorial on his post production work flow, but the additional information given by Dave in this show was also a big help.

I’ve now purchased a boom arm and pop filter for my mic to reduce any artefacts in the recording although as it is still attached to my desk I think I may need to invest in a shock mount although I’m not sure how it will attach to my current Boom arm. Ah well that’s a problem for another day.

As I said this was just a shout out to Al and Dave to say thanks for the show and I will save it for another day to do a show on my new post production work flow on the mintCast audio.

This is Tony Hughes saying goodbye for now.

I ramble on about my impressions of the Odroid-go, a 32 USD handheld system similar to a gameboy built to run game system emulators and various other free software. It’s also built to be harcked.

https://wiki.odroid.com/odroid_go/odroid_go

The summary is this is an easy to put together kit requiring no soldering, and runs classic console emulators pretty well. Well worth the 32 USD plus shipping in my opinion. Claims 10 hours of game play and that seems about right so far for me.

The systems emulated out of the box are:

NES, Game Gear, Gameboy, Gameboy Color, Sega Master System, ColecoVision. Other systems of similar or earlier vintages have emulators that you have to install separately and boot into to run. I don’t think it will emulate newer systems. No Gameboy Advance emulator and I don’t see a Mame emulator. However, I do think this ‘might’ support Mame for some of the early arcade games like Asteroids and Space Invaders.

On the 19th of September 2005 a group of individuals got together to release their first show on the podcast network "Today with a Techie".

The idea was to share knowledge through podcasting. Now 13 years, 2 months, 19 days later the project is still going strong, and you dear listener are a part of it.

Today marks the 2700th episode of "Hacker Public Radio" and coupled with the 300 shows from "Today with a Techie", marks the 3000th episode of this project.

A big thanks goes out to all 354 individual hosts who together contributed 1452 hours of shows to the archive.

There is about 50 giga bytes of mp3 files alone.

Which played back to back gives 60 days 11 hours 40 minutes 21 seconds of continuous play.

If you started listening today and played the shows 24 x 7 you wouldn't be finished listening until Monday, February 5th, 2019.

Of course by then there would be 39 additional shows released, so you still wouldn't be finished.

Despite all this we still don't have a wikipedia page. If you can, please take the time to create one for us. There is plenty of supporting information in the "In the Press" section of our about page.

So to mark the 3000th episode we are going to do nothing more than list the shows, host and summary where available.

Just doing that alone creates a whopping 7 and a half hour episode.

Are you l33t enough to listen to it all ?

Let's go.

Bash Tips - 15

Pitfalls for the unwary Bash loop user

This is the fifteenth episode covering useful tips for Bash users. In the last episode we looked at the 'for' loop, and prior to that we looked at 'while' and 'until' loops. In this one I want to look at some of the loop-related issues that can trip up the unwary user.

Loops in Bash are extremely useful, and they are not at all difficult to use in their basic forms. However, there are some perhaps less than obvious issues that can result in unexpected behaviour.

Long notes

I have provided detailed notes as usual for this episode, and these can be viewed here.

XSV for fast CSV manipulations - Part 1: Basic Usage

https://github.com/BurntSushi/xsv

Introduction

xsv is a command line program for indexing, slicing, analyzing, splitting and joining CSV files. Commands should be simple, fast and composable:

1. Simple tasks should be easy.
2. Performance trade offs should be exposed in the CLI interface.
3. Composition should not come at the expense of performance.

We will be using the CSV file provided in the documentation.

Commands covered in this episode

• count - Count the rows of CSV data
• headers - Show the headers of CSV data, or show the intersection of all headers between many CSV files
• index - Create an index for a CSV file. This is very quick and provides constant time indexing into the CSV file.
• frequency - Build frequency tables of each column in CSV data.
• stats - Show basic types and statistics of each column in the CSV file. (i.e., mean, standard deviation, median, range, etc.)
• sort - Sort CSV data
• select - Select or re-order columns from CSV data.
• slice - Slice rows from any part of a CSV file. When an index is present, this only has to parse the rows in the slice (instead of all rows leading up to the start of the slice).
• search - Run a regex over CSV data. Applies the regex to each field individually and shows only matching rows.
• table - Show aligned output of any CSV data using elastic tabstops.
• flatten - A flattened view of CSV records. Useful for viewing one record at a time.

New podcast - Libre Lounge

Libre Lounge

Quoted from the site:

Libre Lounge is a podcast where we casually discuss various topics involving user freedom, crossing free software, free culture, network and hosting freedom, and libre hardware designs. We discuss everything from policy and licensing to deep dives on technical topics… whatever seems interesting that week. At some point we might even have guests!

Internet Archive funding drive

As you know, HPR uploads all current episodes to the Internet Archive at http://archive.org, and is in the process of uploading older shows, so we are particularly keen that this amazing service continues.

The Internet Archive is currently fundraising. Donations are currently being matched by a generous supporter, so this will double your impact if you are able to donate.

Tags and Summaries

Over the period tags and/or summaries have been added to 23 shows which were without them.

If you would like to contribute to the tag/summary project visit the summary page at https://hackerpublicradio.org/report_missing_tags.php and follow the instructions there.

All medical studies are not alike. Some are of higher quality than others, and the conclusions they reach need to be evaluated based on some principles of good research. Here we take a look at some warning signs of bad or unreliable studies.
