Yeah, I'm late, but AoC itself is scaled down this year due to burnout so gimme a break.

Here's #AdventOfCode Part 1 in two lines of #Matlab (actually I'm using #Octave). Map lines to numbers (L is negative), compute the cumulative sum with 50 as the starting value, mod by 100, and count the zeroes.

```
cells = importdata('input1.txt');
length(find(mod(cumsum([50; cellfun(@(x) str2num(strrep(strrep(x, 'R',''), 'L','-')), cells)]), 100) == 0))
```

For Part 2, my trick was to unroll each rotation of Ln or Rn into n rotations of -1 or +1, respectively. A slightly more cursed one-liner:

```
length(find(mod(cumsum([50; cell2mat(cellfun(@(x) ((substr(x,1,1)=='R')*2-1)*ones(str2num(substr(x,2)), 1), cells, 'UniformOutput',false))]), 100) == 0))
```

The Most Holy Name of the Blessed Virgin Mary

The Feast of the Most Holy Name of the Blessed Virgin Mary is an optional memorial celebrated in the liturgical calendar of the Catholic Church on September 12. It has been a universal Roman Rite feast since 1684, when Pope Innocent XI included it in the General Roman Calendar to commemorate the victory at the Battle of Vienna in 1683.

It was initially removed from the current Church calendar in the liturgical reform following Vatican II. But it was restored by Pope John Paul II in 2002 along with the Feast of the Holy Name of Jesus in January.

In the Eastern Orthodox Church, the feast is celebrated on September 7 in the Antiochian Western Rite Vicariate.

Promoters of veneration of the Holy Name of Mary include St. Anthony of Padua, St. Bernard of Clairvaux, & St. Alphonsus Maria de Liguori. A number of religious orders such as the Cistercian & the Servites, customarily give each member “Mary” as part of their religious name as a sign of honor & of entrustment to the Virgin.

The feast is a counterpart to the Feast for the Holy Name of Jesus on January 3. Its object is to commemorate all the privileges granted upon Mary by God & all the graces received through her intercession & mediation.

The feast day began in 1513 as a local celebration in Cuenca, Spain, celebrated on September 15. In 1587, Pope Sixtus V moved the celebration to September 17. Pope Gregory XV extended the celebration to the Archdiocese of Toledo (Spain) in 1622.

In 1666, the Discalced Carmelites received permission to recite the Divine Office of the Name of Mary 4x a year. In 1671, the feast was extended to the whole Kingdom of Spain. From there, the feast spread. It soon extended to the Kingdom of Naples.

In 1683, the Polish King John Sobieski arrived in Vienna with his army. Before the Battle of Vienna, Sobieski placed his troops under the protection of the Blessed Virgin Mary.

In 1684, to celebrate the victory, Pope Innocent XI added to the Roman calendar, assigning to it the Sunday within the Octave of the Nativity of Mary. An octave, in this case, is the 8th day after a feast, counted inclusively. So this always falls on the same day of the week as the feast itself. The Nativity of Mary refers to a Christian feast day celebrating the birth of the Virgin Mary.

The reform of Pope Pius X in 1911 restored to prominence the celebration of Sundays in their own right, avoiding their being replaced by celebrations from the sanctorale. The sanctorale is 1 of the 2 main cycles that, running concurrently, comprise the Liturgical year in Roman Catholicism, defined by the General Roman Calendar, & used by a variety of Christian denomination.

The celebration of the Holy Name of Mary was moved to September 12. Later in the same century, the feast was removed from the General Roman Calendar in 1969 as part of its reform by Pope Paul VI. As something of a duplication of the September 8 feast of the Nativity of the Blessed Virgin Mary.

But it didn’t cease to be a recognized celebration of the Roman Rite, being mentioned in the Roman Martyrology on September 12. In 2002, Pope John Paul II restored the celebration to the General Roman Calendar.

William Joseph Chaminade chose the Feast of the Holy Name of Mary as the patronal feast of the Society of Mary (Marianists). Rather than a day commemorating a particular dogma or devotion in order to focus on the person of Mary.

St. Martin’s Day

This is also called Martinmas or Martlemas. It’s historically called Old Halloween or All Hallows Eve.

This is the feast day of St. Martin of Tours. St. Martin of Tours was the 3rd Bishop of Tours. He’s the patron saint of many communities & organizations across Europe, including France’s Third Republic. It was celebrated in the liturgical year on November 11.

During the Middle Ages & early modern period, it was an important festival in many parts of Europe. Particularly in Germanic-speaking countries. In these areas, it started at the end of the harvest season, the beginning of the cold season, & the “winter revelling season.”

Traditions include feasting on goose or beef, drinking the first wine of the season, & mumming. Mumming is groups of men & women from the medieval to early modern era who are dressed in fantastical clothes, & costumes, & serenaded people outside their houses, or joined the party inside. Costumes varied including bears, deer, rams, or unicorns.

In some German & Dutch-speaking towns, there are processions of kids with lanterns (Laternelaufen), sometimes led by a horseman representing St. Martin. The saint was also said to bestow gifts to kids. In the Rhineland, it’s also marked by lighting bonfires.

Traditionally, in many parts of Europe, St. Martin’s Day marked the end of the harvest & the beginning of winter. The feast dovetails with the end of the Octave of Allhallowtide.

Martinmas was when livestock was slaughtered for winter supplies. Goose is eaten at Martinmas in most places. There’s a legend that St. Martin, when trying to avoid being ordained a bishop, hid in pin of geese whose noise gave him away.

In the wine growing regions of Europe, the first wine was ready around the time of Martinmas. St. Martin is widely credited in France with helping to spread winemaking throughout the region of Tours (Touraine) & facilitating vine-planting. He’s also credited with introducing the Chenin blanc grape. Most of the wine of western Touraine & Anjou is made from these grapes.

In the Rhineland region of Germany, bonfires are lit on St. Martin’s Eve. In the 15th century, the bonfires were so many that the festival got the nickname: Funkentag (Spark Day). In the 19th century, it was recorded that young people danced around the fire & leapt through the flames. The ashes were strewn on the fields to make them fertile.

In some German & Dutch-speaking towns, there are nighttime processions of kids carrying paper, or turnip, lanterns & singing songs of St. Martin.

In parts of Flanders & the Rhineland, processions are led by a man on horseback representing St. Martin. This man on horseback may give out apples, nuts, cakes, or other sweets to the kids.

In Ypres, kids hung up stockings filled with hay on Martinmas Eve. They woke up the next morning to find gifts in the stockings. The gifts were said to have been left by St. Martin was thanks for the fodder provided for his horse.

In the Swabia & Ansbach regions of Germany, a character called Pelzmarten (‘pelt Martin” or “skin Martin”) appeared at Martinmas until the 19th century. With a black face & wearing a cow bell, he ran about scaring the kids & he gave out “blows” as well as nuts & apples.

In the 6th century, church councils began requiring fasting on all days, except on Saturdays & Sundays, from St. Martin’s Day to the Epiphany on January 6 (That’s 56 days.). Elsewhere, the Feast of the Three Wise Men for the stopping of the star over Bethlehem.

An addition to & equal to the 40 days of Lent, given its weekend breaks, this was called Quadragesima Sancti Mantini (St. Martin’s Lent or literally “the 40th of”). This is rarely observed now.

This period was shortened to begin on the Sunday before December & became the current Advent within a few hundred years. In the Archdiocese of Milan according to Ancient Ambrosian Liturgical usage the feast of St. Martin is followed by the First Sunday in the Advent (the 6-week period) is still used in this large Diocese & the Churches outside it, such as in Ticino (Switzerland) that do still use the Ambrosian Liturgy.

In the United States, St. Martin’s Day celebrations are uncommon. But are usually held by German-American communities. Many German restaurants feature a traditional menu with goose & Gluhwein (a mulled red wine). St. Paul Minnesota celebrates with a traditional lantern procession around Rice Park. The evening includes German treats & traditions that highlight the season of giving. In Dayton, Ohio, the Dayton Liederkranz-Turner organization hosts a St. Martin’s Family Celebration on the weekend with an evening lantern parade to the singing of St. Martin’s carols, followed by a bonfire.

L'activité cyclonique tropicale continue à être relativement forte avec les différents systèmes suivants :

- La dépression tropicale #Shakhti circule au large du Yémen et pourrait prendre une trajectoire est en se rapprochant des côtes indiennes.

- Le #typhon #Halong s'est quant à lui largement renforcé en devenant de catégorie 4, il circule au sud du Japon. Il devrait s'affaiblir d'ici 24 à 48 heures et d'ici 48 à 72 heures, il sera repris par le courant jet nord Pacifique en effectuant sa transition extra-tropicale. Cela contribuera à amplifier une dorsale anticyclonique en direction de l'Alaska tandis qu'un talweg glissera en aval sur l'ouest américain.

- Une autre onde tropicale est toujours surveillé sur l'ouest du Pacifique. Elle a de bonnes probabilités de développer une tempête tropicale. Sa direction suivrait celle de Halong en circulant au sud du Japon.

- Sur l'est du Pacifique, #Octave tempête tropicale circule loin des terres habitées et devrait s'affaiblir petit à petit.

- Ce n'est pas le cas de #Priscilla qui s'est bien renforcé pour devenir un #ouragan de catégorie 2. Impacts importants précédemment sur les Etats de Colima et Jalisco au Mexique avec des inondations, et impacts importants à venir en Basse Californie avec de même des inondations à redouter. Les secteurs de Los Cabos et La Paz sont fort exposés. Conséquences non négligeables aussi à nos latitudes moyennes en alimentant dès la fin du week-end à venir une rivière atmosphérique sur les USA remontant jusqu'au Canada. Cela va réalimenter en aval le blocage anticyclonique sur le nord-est du Canada. Encore des températures records à prévoir la semaine prochaine entre Québec, Nouvelle Ecosse, Ontario, Terres Neuves et Labrador.

- Une autre onde tropicale se développe au large du Mexique et devrait aboutir à une tempête tropicale, on peut s'attendre à des intempéries sur les côtes Mexicaines et éventuellement plus tard sur la Basse Californie.

- Sur l'Atlantique, #Jerry tempête tropicale circule en direction des petites Antilles qu'il devrait tangenter vendredi et samedi. On peut s'attendre à des impacts avec forte houle, fortes pluies et des rafales de vent notamment de la Guadeloupe aux îles Vierges. Porto Rico pourrait être touché également.
En remontant vers le nord, Jerry devrait se renforcer pour devenir un #ouragan de catégorie 2. Par la suite, sa trajectoire l'amènera à interagir avec le courant jet nord atlantique vers le milieu de semaine prochaine, ou éventuellement circuler un peu plus au sud en direction des Açores. Influence certainement importante sur les centres d'action entre Atlantique et Europe. Cela pourrait réalimenter le blocage nord européen sur la deuxième partie de semaine prochaine.

- Une autre onde tropicale est sous surveillance dans le baie de Campèce avec pour l'heure des capacités de développement limitées.
