Fifteen more songs set to be included in Harmonix’s next rhythm-action game Fuser have been revealed today, giving us a better glimpse at the title’s 100+ song soundtrack.

First revealed in February, Fuser is described by the Rock Band and Guitar Hero developer as a “revolutionary new music gaming experience” and “the next evolution of interactive music gaming”. 16 songs were revealed during that initial announcement, so this latest batch will be available to play in addition to those previously teased.

Here are the newly revealed songs:

• Armin van Buuren “Blah Blah Blah”
• Brad Paisley “Mud On The Tires”
• Cardi B “Bodak Yellow”
• Carly Rae Jepsen “Call Me Maybe”
• Coldplay “Clocks”
• Dua Lipa “Don’t Start Now”
• DMX “X Gon’ Give It To Ya”
• Grand Master Melle Mel “The Message (2012)”
• Jonas Brothers “Sucker”
• Macklemore & Ryan Lewis ft. Wanz “Thrift Shop”
• Nelly “Hot In Herre”
• Panic! At The Disco “High Hopes”
• Pitbull ft. Ne-Yo, Afrojack & Nayer “Give Me Everything”
• Whitney Houston “I Wanna Dance With Somebody (Who Loves Me)”
• Zedd ft. Maren Morris & Grey “The Middle”

The game lets players fuse together elements from hit songs across pop, rap/hip-hop, R&B, dance, rock, country, Latin and Caribbean music into all-new mixes, with vocals, bass lines, and other instrumentation being blended together during gameplay.

It sounds interesting, for sure. Here’s hoping it’ll live up to Harmonix’s “revolutionary” remarks when it launches this fall.

To join a list of DataFrames, say dfs, use the pandas.concat(dfs) function that merges an arbitrary number of DataFrames to a single one.

When browsing StackOverflow, I recently stumbled upon the following interesting problem. By thinking about solutions to those small data science problems, you can improve your data science skills, so let’s dive into the problem description.

Problem: Given a list of Pandas DataFrames. How to merge them into a single DataFrame?

Example: You have the list of Pandas DataFrames:

df1 = pd.DataFrame({'Alice' : [18, 'scientist', 24000], 'Bob' : [24, 'student', 12000]})

df2 = pd.DataFrame({'Alice' : [19, 'scientist', 25000], 'Bob' : [25, 'student', 11000]})

df3 = pd.DataFrame({'Alice' : [20, 'scientist', 26000], 'Bob' : [26, 'student', 10000]}) # List of DataFrames

dfs = [df1, df2, df3]

Say, you want to get the following DataFrame:

 Alice Bob

0 18 24

1 scientist student

2 24000 12000

0 19 25

1 scientist student

2 25000 11000

0 20 26

1 scientist student

2 26000 10000

You can try the solution quickly in our interactive Python shell:

Exercise: Print the resulting DataFrame. Run the code. Which merging strategy is used?

Method 1: Pandas Concat

This is the easiest and most straightforward way to concatenate multiple DataFrames.

import pandas as pd df1 = pd.DataFrame({'Alice' : [18, 'scientist', 24000], 'Bob' : [24, 'student', 12000]})

df2 = pd.DataFrame({'Alice' : [19, 'scientist', 25000], 'Bob' : [25, 'student', 11000]})

df3 = pd.DataFrame({'Alice' : [20, 'scientist', 26000], 'Bob' : [26, 'student', 10000]}) # list of dataframes

dfs = [df1, df2, df3] df = pd.concat(dfs)

This generates the following output:

print(df) ''' Alice Bob

0 18 24

1 scientist student

2 24000 12000

0 19 25

1 scientist student

2 25000 11000

0 20 26

1 scientist student

2 26000 10000 '''

The resulting DataFrames contains all original data from all three DataFrames.

Method 2: Reduce + DataFrame Merge

The following method uses the reduce function to repeatedly merge together all dictionaries in the list (no matter its size). To merge two dictionaries, the df.merge() method is used. You can use several merging strategies—in the example, you use "outer":

import pandas as pd df1 = pd.DataFrame({'Alice' : [18, 'scientist', 24000], 'Bob' : [24, 'student', 12000]})

df2 = pd.DataFrame({'Alice' : [19, 'scientist', 25000], 'Bob' : [25, 'student', 11000]})

df3 = pd.DataFrame({'Alice' : [20, 'scientist', 26000], 'Bob' : [26, 'student', 10000]}) # list of dataframes

dfs = [df1, df2, df3] # Method 2

from functools import reduce

df = reduce(lambda df1, df2: df1.merge(df2, "outer"), dfs)

This generates the following output:

print(df) ''' Alice Bob

0 18 24

1 scientist student

2 24000 12000

3 19 25

4 25000 11000

5 20 26

6 26000 10000 '''

You can find a discussion of the different merge strategies here. If you’d use the parameter "inner", you’d obtain the following result:

 Alice Bob

0 scientist student

PICO-8 is perhaps the most popular of the fantasy consoles and if you are extremely quick, you can pick it up as part of the Itch.io Racial Justice bundle along with a ton of other development tools and indie games.  PICO-8 is described as:

PICO-8 is a fantasy console for making, sharing and playing tiny games and other computer programs. It feels like a regular console, but runs on Windows / Mac / Linux. When you turn it on, the machine greets you with a commandline, a suite of cartridge creation tools, and an online cartridge browser called SPLORE.

It emulates a very limited virtual machine:

Display
128×128 16 colours

Cartridge Size
32k

Sound
4 channel chip blerps

Code
Lua

Sprites
256 8×8 sprites

Map
128×32 cels

Additionally PICO-8 has several built in tools including a sprite editor, sound editor, level editor and music editor, as well as tools for publishing and sharing your creations with out.  The underlying programming language is Lua and is documented here.  You can check out PICO-8 in action in the video below.

This series builds on the previous articles: Typeset your docs with LaTex and TeXstudio on Fedora and LaTeX 101 for beginners. This first part of the series is about LaTeX lists.

Types of lists

LaTeX lists are enclosed environments, and each item in the list can take a line of text to a full paragraph. There are three types of lists available in LaTeX. They are:

• Itemized: unordered or bullet
• Enumerated: ordered
• Description: descriptive

Creating lists

To create a list, prefix each list item with the \item command. Precede and follow the list of items with the \begin{<type>} and \end{<type>} commands respectively where <type> is substituted with the type of the list as illustrated in the following examples.

Itemized list

\begin{itemize} \item Fedora \item Fedora Spin \item Fedora Silverblue

\end{itemize}

Enumerated list

\begin{enumerate} \item Fedora CoreOS \item Fedora Silverblue \item Fedora Spin

\end{enumerate}

Descriptive list

\begin{description} \item[Fedora 6] Code name Zod \item[Fedora 8] Code name Werewolf

\end{description}

Spacing list items

The default spacing can be customized by adding \usepackage{enumitem} to the preamble. The enumitem package enables the noitemsep option and the \itemsep command which you can use on your lists as illustrated below.

Using the noitemsep option

Enclose the noitemsep option in square brackets and place it on the \begin command as shown below. This option removes the default spacing.

\begin{itemize}[noitemsep] \item Fedora \item Fedora Spin \item Fedora Silverblue

\end{itemize}

Using the \itemsep command

The \itemsep command must be suffixed with a number to indicate how much space there should be between the list items.

\begin{itemize} \itemsep0.75pt \item Fedora Silverblue \item Fedora CoreOS

\end{itemize}

Nesting lists

LaTeX supports nested lists up to four levels deep as illustrated below.

Nested itemized lists

\begin{itemize}[noitemsep] \item Fedora Versions \begin{itemize} \item Fedora 8 \item Fedora 9 \begin{itemize} \item Werewolf \item Sulphur \begin{itemize} \item 2007-05-31 \item 2008-05-13 \end{itemize} \end{itemize} \end{itemize} \item Fedora Spin \item Fedora Silverblue

\end{itemize}

Nested enumerated lists

\begin{enumerate}[noitemsep] \item Fedora Versions \begin{enumerate} \item Fedora 8 \item Fedora 9 \begin{enumerate} \item Werewolf \item Sulphur \begin{enumerate} \item 2007-05-31 \item 2008-05-13 \end{enumerate} \end{enumerate} \end{enumerate} \item Fedora Spin \item Fedora Silverblue

\end{enumerate}

List style names for each list type

Default style by list depth

Setting list styles

The below example illustrates each of the different itemiszed list styles.

% Itemize style

\begin{itemize} \item[$\ast$] Asterisk \item[$\diamond$] Diamond \item[$\circ$] Circle \item[$\cdot$] Period \item[$\bullet$] Bullet (default) \item[--] Dash \item[$-$] Another dash

\end{itemize}

There are three methods of setting list styles. They are illustrated below. These methods are listed by priority; highest priority first. A higher priority will override a lower priority if more than one is defined for a list item.

List styling method 1 – per item

Enclose the name of the desired style in square brackets and place it on the \item command as demonstrated below.

% First method

\begin{itemize} \item[$\ast$] Asterisk \item[$\diamond$] Diamond \item[$\circ$] Circle \item[$\cdot$] period \item[$\bullet$] Bullet (default) \item[--] Dash \item[$-$] Another dash

\end{itemize}

List styling method 2 – on the list

Prefix the name of the desired style with label=. Place the parameter, including the label= prefix, in square brackets on the \begin command as demonstrated below.

% Second method

\begin{enumerate}[label=\Alph*.] \item Fedora 32 \item Fedora 31 \item Fedora 30

\end{enumerate}

List styling method 3 – on the document

This method changes the default style for the entire document. Use the \renewcommand to set the values for the labelitems. There is a different labelitem for each of the four label depths as demonstrated below.

% Third method

\renewcommand{\labelitemi}{$\ast$}

\renewcommand{\labelitemii}{$\diamond$}

\renewcommand{\labelitemiii}{$\bullet$}

\renewcommand{\labelitemiv}{$-$}

Summary

LaTeX supports three types of lists. The style and spacing of each of the list types can be customized. More LaTeX elements will be explained in future posts.

We normally look to games like The Legend of Zelda: Breath of the Wild for brand new fan discoveries, but today it’s Super Mario Odyssey‘s turn to hog the limelight.

A speedrunner going by the name of Xdxboxjaja has uploaded the following clip online, giving us a good look at what appears to be a brand new wall clip discovery. It can be performed in the Snow Kingdom and allows a player to grab that world’s 18th Power Moon, ‘Ice-Dodging Goomba Stack’ in record time.

Usually, you’d have to capture a Goomba, jump on more of them to create a stack of four, then work your way over to a button to reveal the Moon (full guides to each of the game’s Moons can be found here). With this new method, however, you can skip all of this and simply use Mario’s jumping abilities to go straight through a wall.

Xdxboxjaja believes that the new discovery should shave off around eight seconds for any speedrunners focusing on beating the game in the fastest time possible. Even if you’re not a speedrunner, though, you can still have a bit of fun trying to pull this off.

Just a few weeks ago, another Super Mario Odyssey player found a way to skip a good chunk of the final boss battle.

The new mobile games announcements keep on coming. NetEase and Warner Bros. have revealed that they’re working on a new strategy title based on The Lord of the Rings. Little is known about The Lord of the Rings: Rise to War apart from the genre. The Lord of the Rings: Rise to War release date is currently unknown, too. So it may be a while before you learn anything else.

“With NetEase, we have an excellent partner for The Lord of the Rings: Rise to War bringing gamers the mobile experience in this rich universe they are looking for,” says Warner Bros. president David Haddad. “This adaptation will unlock new opportunities for players to explore the iconic settings and characters of Middle-earth while utilizing their strategic skills in battle.”

This isn’t the first time NetEase and Warner Bros have worked together. NetEase is also working on a mobile RPG game with card elements based on Harry Potter. It’s called Harry Potter: Magic Awakened, and it’s currently being tested in China. Not much on a Harry Potter: Magic Awakened release date there, either – but as it’s now in beta, we have more hope that you can play that one sooner.

If you don’t fancy waiting to get your strategy fix, though, then you can always check out our best mobile strategy games article. We also have a list of upcoming mobile games, too, so you can see some of the best games releases that are over the horizon.
