València in Spain is well known in art from the dozens of paintings of well-dressed young ladies on its beaches, made by Joaquín Sorolla during the early years of the twentieth century. This weekend I look at how his art evolved from his earlier works of social realism to reach the brightly lit beach.
Sorolla was born in València in 1863, and started learning to draw and paint at the age of nine. Among his teachers when he was studying in his home town was another Valèncian, Ignacio Pinazo Camarlench (1849-1916), who had developed a loose Impressionist style in 1874.
In 1887, shortly after Pinazo stopped teaching at the Academy, he painted one of the earliest depictions of Malvarrosa Beach, the most popular in València, a painting almost certainly seen by the young Sorolla.
Sorolla would also have seen and been influenced by the paintings of Francisco Pradilla (1848-1921) from Zaragoza, a history painter who had been Director of the Academy of Spain in Rome, and Enrique Simonet (1866-1927), another Valèncian.
Simonet must have painted his Málaga Beach at Dusk when he was back in Spain during a visit from his studies in Rome in 1889. It shows well his increasing attention to detail which was taking him away from his early Impressionist style.
By the 1890s, although working primarily in Madrid, Sorolla began to use the fishermen of València as a source of motifs. Early among those is this man Peeling Potatoes (1891) in one of the fishing boats hauled up just above the sea on the beach there. Relatively small and quite sketchy, this may have been a study he intended to develop into a larger more finished work.
Sorolla’s And They Still Say Fish is Expensive! from 1894 is set in the hold of one of the larger fishing vessels, amid spare tackle, a large barrel, and some of its catch. Two older men are attending to a youth, who appears to have been wounded, presumably as the result of an accident at sea. Around the boy’s neck is a pendant good-luck charm; he is stripped to the waist and pale, and one of the men is pressing a dressing against his abdomen. Lit from an open hatch at the top left, the painting has the immediacy of a photographic snapshot and looks documentary.
Sorolla’s title is incisive social comment about the values of a society that was happy to see young boys go to sea to fish, putting their lives at risk for those ashore to enjoy cheap seafood. This was painted during the summer of 1894, again in València, and went on to great acclaim in the Paris Salon the following year, where it was bought for the Museo del Prado in Madrid.
At the same time that he was painting that work, Sorolla was busy on his even larger Return from Fishing (1894), now one of the most visually impressive exhibits in the Musée d’Orsay in Paris, following its purchase for the French state from the Salon of 1895, where it won a gold medal. Romantic though this may appear today, it’s a carefully detailed account of the complex, strenuous, dangerous and above all primitive working conditions of the local fishermen of València, who still used teams of oxen to haul their boats up the beach.
Valencian Fishermen (1895) is perhaps a little more relaxed, and a far smaller essay on the work of the fishermen as they maintain their gear at the water’s edge.
Although known primarily for his portraits and figurative works, Sorolla painted some fine landscapes, which may have had a more personal significance. The Cape of San Antonio, Jávea from 1896 shows this part of the southern end of the Gulf of Valencia, here from Cap Marti to the south.
Sorolla’s best-known painting from this Naturalist period is his large Sad Inheritance (1899), which won him the Grand Prix and medal of honour at the 1900 Exposition Universelle in Paris, and a medal in Madrid the following year. As ever, its apparent spontaneity is deceptive: this is one of his most carefully prepared paintings.
It shows a group of young boys from a local charitable hospital enjoying a visit to the sea in the care of a lone priest, and celebrates the mission of the Hospitaller Order of St John of God, who had built the hospital in 1892 at the end of Malvarrosa Beach (Platja de la Malva-rosa). Sorolla later said that he had witnessed this scene one evening in a remote corner of the beach, and once he had been given permission to paint the boys, he made an initial oil sketch from memory.
Although Sad Inheritance was Sorolla’s last large Naturalist painting, he continued to create works in similar style. Lunch on the Boat, painted the previous year, shows a group of Valèncian men and boys eating an improvised lunch under the awning on their fishing boat.
This weekend I look at two Italian duchesses, today Isabella d’Este (1474-1539), Duchess of Mantua, and tomorrow her rival Lucrezia Borgia (1480-1519), Duchess of Ferrara, Modena and Reggio, and lover of Isabella’s husband.
Isabella d’Este was an unusually well-educated woman who became one of the best-known of all the Renaissance patrons of art. She was born to the Duke of Ferrara and his wife Eleanor of Naples in 1474, the oldest and favourite of their children. Her mother ensured she received an excellent education, even by male standards of the day, emphasising the classics including Greek and Latin. She seems to have struggled more in learning to read Latin, and in adult life received additional lessons to help her reading skills. She was particularly fond of music, singing and dancing, and learned to play several instruments including the lute and harpsichord. Her taste in music was predominantly secular.
When she was only six years old she was betrothed to Francesco, who was expected to succeed as Marquess of Mantua, a city and small province in Lombardy, about a hundred miles (160 km) from Venice. They were married by proxy ten years later, by which time the young Francesco had inherited both title and realm, which he was to rule until his death in 1519. He was also the commander-in-chief of the army of the Republic of Venice, which frequently took him away from their palace in Mantua. In 1509, he was held captive as a hostage in Venice, and wasn’t released for three years.
Although Isabella had eight children between 1493-1508, six of whom survived into adult life, a remarkably high figure for the time, her marriage was blighted by Francesco’s sexual incontinence. His most famous affair was with the notorious Lucrezia Borgia, which started in 1503, and only came to an end when Francesco contracted syphilis from his contacts with prostitutes.
In contrast, Isabella seems to have lived a virtuous life and became an accomplished statesman and diplomat, with shrewd political judgement even when dealing with the likes of Cesare Borgia. She saw Mantua promoted to a Duchy, and ruled it from the death of Francesco in 1519 until her son Federico came of age some years later. She still hankered after political involvement, and in 1527 moved to Rome. On her return to Mantua, she promoted the education of girls and finally took charge of the town of Solarolo until her death in 1539, at the age of 64.
Isabella started to collect objets d’art soon after she moved to her palace in Mantua. As far as paintings are concerned, she was foremost a collector who relied on the advice of others in the court, rather than a connoisseur in her own right. Surprisingly, her purchases had to be made from her own wealth, which was quite limited, and in times of hardship she resorted to pawning jewellery to raise funds. Her patronage concentrated mainly on music and sculpture. She was unusual for promoting women as singers and placing them in choirs. Her literary sponsorship was limited: she seems to have enjoyed swashbuckling stories of chivalry, such as those in Ludovico Ariosto’s Orlando Furioso, and was a loyal supporter of his work.
Her sponsorship and taste in paintings is largely reflected in the works she commissioned for her private study, her famous studiolo, which thankfully have been well preserved as they passed to the French Kings, and most are now in the Louvre as a result. Combined with records in her copious correspondence and a crucial inventory, her studiolo has been reconstructed in detail. Her period of collecting covered the appointments of two court painters in Mantua: Andrea Mantegna until his death in 1506, thereafter Lorenzo Costa. When Isabella was most active in collecting paintings in the early 1500s, Mantegna was around 70 years old, and Costa in his forties.
Mantegna arranged to be recommended to Isabella through her former tutor, but his first attempt to impress her with a portrait in 1493 met with a stony reception: Isabella declined it as being so badly painted that it didn’t resemble her.
Despite that discouraging start, her first commission for a painting for her study was awarded to Mantegna, for his painting of Mars and Venus, known better as Parnassus (1496-97). She had apparently grown to like his finely finished and old-fashioned tempera paintings, and the artist probably painted this largely in tempera, only for it to be repainted using oils after his death.
This refers to the classical myth of the affair between Mars and Venus, the latter being married to Vulcan, who caught them in bed together and cast a fine net around them for the other gods to come and mock their adultery. The lovers are shown standing together on a flat-topped rock arch, as the Muses dance below. To the left of Mars’ feet is Venus’ child Cupid aiming his blowpipe at Vulcan’s genitals, as he works at his forge in the cave at the left. At the right is Mercury, messenger of the gods, with his caduceus and Pegasus the winged horse. At the far left is Apollo making music for the Muses on his lyre.
It’s an unusual theme for a woman of the time to have chosen, although it has largely been interpreted with reference to a contemporary poem that seems less concerned with the underlying story of adultery exposed.
A couple of years later, Isabella returned to commission Mantegna to paint a more moralistic allegory of The Triumph of the Virtues, or Pallas Expelling the Vices from the Garden of Virtue (1499-1502), again largely in tempera. The scene is a garden with a pond, near a river meandering down to a lush valley in the distance. Inside its arched perimeter Pallas Athena, at the left with her distinctive helmet and shield, is chasing away figures representing the Vices.
At the far left is a tree representing Virtue Deserted, and to the right of Athena’s feet is the armless Vice of Idleness. Also in the pond is a centaur who carries a standing figure, usually read as Diana, on its back. At the far right is the Virtue of Prudence represented as a message from within her prison, and in the sky are the Virtues of Justice, Temperance and Fortitude.
An unusual and personal twist indicating the extent of Isabella’s involvement in this composition is Athena’s spear. Although one of her normal attributes, its head has broken off and rests on the ground. This is a reference to a broken lance that Francesco presented to Isabella following his command of the Holy League (Venetian) forces at the Battle of Fornovo in 1495.
After Leonardo da Vinci had painted The Last Supper, he visited the court at Mantua, where he made this chalk Portrait of Isabella d’Este (c 1499-1500). Isabella apparently disliked wasting time sitting for portraits, and this elegant profile is one of few known to have been made of her. Leonardo and Isabella corresponded afterwards, she inviting him to undertake commissions for her including one for a painting of Christ at the age of twelve, but he turned her offers down.
She was also unsuccessful in getting Giovanni Bellini to paint a proper commission for her. She had originally asked him in 1496 to paint an allegory, no doubt destined for her study, but by late 1502 she reluctantly wrote that she’d settle for a Nativity so long as it included Joseph, “the beasts” and Saint John the Baptist. Bellini refused to include the last of those, which she finally agreed to. His painting arrived in 1504, but that work now appears to be lost. Isabella asked Bellini a third time in 1505, promising not to hold him to any detailed description of the painting, but nothing came of that.
Isabella’s third painting was made by another artist reaching the end of his career, Pietro Perugino (1448–1523), who is believed to have taught Raphael. The latter may have been working for Perugino at the time that his former master painted The Combat of Love and Chastity in 1503, using Mantegna’s favourite medium of tempera despite Perugino’s accomplishment in oils.
Mantegna worked in Mantua, so little of Isabella’s correspondence gives insight into the process of his commissions. She had to write to Perugino, though, and there’s a trail of letters revealing how much detail she specified about this work, even supplying a drawing. Its theme is literary, as laid down in the contract by Isabella’s court poet, and shows a fight between the personifications of Love and Chastity, which may have worked well in words but doesn’t translate into visual art at all well.
It features a gamut of mythological figures in no particular order, including Apollo and Daphne, Jupiter and Europa, Polyphemus and Galatea, and Pluto and Proserpina – all couples in which the man abducted and/or raped the woman. In front is Pallas Athene about to kill Eros with a lance, and a more even match between Diana with her bow and Venus, who is singeing the huntress with a burning brand. Isabella laid out strict instructions, for example requiring that Venus, who is traditionally shown naked, was clothed. Even the owl perched in the branches of the sacred olive tree at the left was prescribed in the commission. When Perugino didn’t follow these, she protested, and on completion she wrote that it should have been better finished to set alongside her Mantegnas, and was clearly unimpressed. For this the artist was paid a mere 100 ducats.
Isabella then turned to Lorenzo Costa (1460–1535) for The Garden of the Peaceful Arts or The Crowning of a Female Poet (1504-06), painted in oil and tempera. Mantegna had originally been commissioned to paint this, but died before he could make much progress. Costa started from scratch, and under Isabella’s direction according to her poet’s literary theme produced this strange painting often known as an allegory of Isabella’s coronation, or construed as an account of Sappho’s career.
Figures identified include Diana, at the front on the right, and Cadmus, but reading this work coherently now seems impossible.
Another commission that Mantegna had started to work on before he died was completed by Costa in 1511, The Reign of Comus, again using tempera for a complex composition. Comus, ruler of a land of bacchanalia, sits talking to a near-naked Venus in the left foreground. Just to the right of the centre foreground, Nicaea is lying unconscious through alcohol, against Dionysus (Bacchus), who got her into a stupor so that he could rape her.
Under the arch is the unmistakable two-faced Janus with Hermes, apparently repelling potential newcomers to the bacchanal. In the centre is a small group of musicians, and various naked figures are cavorting in the waters behind.
Isabella is believed to have commissioned other paintings that weren’t destined for her study, including some religious works.
One surviving painting that appears to have been commissioned by Isabella but remained outside the private world of her study is by Francesco Bonsignori (1460–1519), who made this chalk study of Isabella d’Este in 1519.
Bonsignori’s painting of the Blessed Osanna Andreasi followed later that year. This beatified Mantuan woman was the daughter of a Gonzaga, who started reporting visions when she was only six. She rejected an arranged marriage and secretly took orders, becoming a Dominican tertiary. She developed stigmata, learned to read and write in a miracle, and became a mystic. She died in Mantua in 1505, and Isabella led the campaign for her veneration.
Isabella is shown in profile, kneeling at the left, with her lifelong friend Margherita Cantelma. On the right, among the Dominican nuns, is Isabella’s daughter Ippolita, one of three of her children who took holy orders.
Late additions to Isabella’s study were a pair of tempera allegories by Antonio da Correggio (1489–1534), Allegory of Vices (1529-30) above, and Allegory of Virtues (1531) below. The latter reflects a detailed commission, as it shows once again Pallas Athena holding the broken spear that Francesco had brought back from battle for Isabella.
Inevitably, her portrait was painted by Titian (1490–1576). The original version from 1523 was made from life, but in about 1536, when she was in her early sixties, she sent an old portrait made by Francia in 1511 for Titian to paint from, with suitably updated fashionable dress of the day. The result is the anachronistic Isabella d’Este, Duchess of Mantua, which flatters more than it reveals.
With few exceptions, Isabella’s commissions were very personal, so much so that their elaborate stories and allegories are now elusive. More than one of the artists who painted for her must, at some stage, have wished that she had learned to paint. Those masters were used as proxy craftsmen, to turn the words of her court poet into images for her study. No doubt she amazed distinguished guests by explaining their symbols and references when they were taken on a tour of her collection.
Isabella’s understanding of visual art was limited, her paintings fascinating, but of no consequence to the Renaissance or the history of painting. For the great masters of the day, who were changing art history by their paintings, Isabella’s commissions were to be avoided like the plague. They would have been archaic in style, stifled original creation, and could only have led to great dissatisfaction for all concerned.
Isabella d’Este was an outstanding example of what education and ability can achieve, and a great woman of any age. But as far as painting is concerned, her reputation as a great and influential patron is at best misleading.

有时候,我有个很想要的装备,但市面上完全没有这种产品。因为不是刚需,没必要自己 diy,慢慢地想法也就淡了。过了很多年,突然发现,终于有人把类似的东西设计出来卖。
譬如,几年前和圣途望远镜聊过,(它家是代工国外大牌望远镜起家,非常物美价廉的一家),说把你们的屋脊望远镜,做个单筒版的呀。有的用户譬如我,不长时间盯着看的话,用一只眼就够了。重量和体积减少一半,便携性会好很多。
老板鄙视地说:我们才不做这么不专业的东西!
后来我也没再关注了……刚发现,厂商自我反思,2019 年悄悄去做了单筒款。我上手体验了一番,确实像我期待的那样好用。
老板居然还在淘宝页面,写了一堆心路历程。笑死~~
譬如,2019 年,我自己 3D 打印了一堆,钢笔墨囊的塞子。当时还说要发攻略,后来懒癌发作,就放了鸽子。如今淘宝上已经有成品在卖了……
譬如,我很多年前就想要的:可以装通用手术刀片的便携折刀。
最近也有在卖了。而且我发现的时候,淘宝上已经很卷了,有很多款设计,钛合金才几十块钱。挑了一圈,大部分都不支持锁定。好不容易找到一家框式锁定的,大概是因为带锁定会涉及管制刀具,商家也不敢明说,连背面锁定部分的图片,都不敢放出来。重量 30g。还有一款是甩刀的设计,略重一点(45g),但居然两面可以分别兼容 3、4 号刀柄的手术刀片。拿到手之后,手感也确实像我当年期望的一样舒适。
其实带锁定也只是我的习惯性执念,这种薄刀片并不会大力使用,于是锁定功能并不是必须的。没有锁定功能的刀,可以做的更小,用三号刀架,重量能到 10g 以内,更加便携。但我个人觉得太小了没手感,四号刀架刚刚合适。
常见的两种手术刀柄的接口:
这东西相对于普通折刀,优点:
缺点:
标题源自康德的「物自体」的概念(嗯,我又在扯淡)。
有时也想,要不要自己也把一些好玩设计,做出产品来卖着玩。但没有稳定的居住方式的话,开这种店很麻烦。
说起水壶,突然发觉,日常接触的人,就没见过几个人用 SIGG 水壶的;包括背包旅行和户外徒步时,也很少见到用这种铝制水壶的。为什么呢?我一直觉得这东西很好用啊。作为超过 20 年的老用户,换过六七个,基本都是丢失了立刻再买一个。
当我说 SIGG 水壶时,并不包括这个牌子的其它产品,而只是指最经典的铝壳水壶款式,搭配最原始的旋转瓶盖(试过用嘴吸的快速瓶盖,不好用,也很难清洗)。也未必仅限于瑞士 SIGG 的牌子,西班牙的 Laken 也很好用(我不清楚是否涉及专利)。当然,这样的设计已经到处都是了,10 块钱就能买到山寨版。日常参加个超市活动,就能收到一模一样的山寨赠品……大厂商的正品,与之相比,在以下这些方面,都要靠谱很多:
这种铝壳水壶的户外「竞品」,大概有以下几种:
每种水壶,适用的场合不同。当然不能说 SIGG 的铝瓶在一切场合,都胜过所有其它水壶。但对我来说,这种水壶,在日常的很多场合,其综合实用性更高。
而相对来说,一些「缺点」,对我来说,并不是很重要:
另外,有一个专属于水袋的优点:水不满的时候,不会在瓶里摇晃,浪费体力。这个确实是其它水壶难以做到的。而且水壶容量越大,问题越严重。但我用的铝瓶只有 0.6L,摇晃消耗的体力并不严重。长途徒步时,我也会带几个大可乐瓶装水,铝瓶的水喝完了,再从其它瓶子灌进来,让其它瓶子始终保持全满或全空的状态。
金属水壶的优势
SIGG 这种铝壳水壶,就是早期的金属军用水壶,在现代技术下的轻便款。它的「不保温」、「导热性太强」,其实并不能算缺点,反而是这类水壶的优点。户外有很多场景,是只有这种水壶,才能更方便地做到的:
曾经忘在冰箱冷冻室里的水壶……我还以为结冰膨胀后,会是瓶盖被顶出来,但居然是整个瓶身涨裂了。
一些 SIGG 的业界八卦
虽然 SIGG 号称创建于 1908 年(名字源于瑞士创始人 Ferdinand Sigg),但长年来都是在做家用铝制品,水壶的设计,直到 1980 年才问世。最初也用这个形状,给 MSR 等户外炉具品牌做油壶,但因为技术含量不高,很快 MSR 就自己做油壶了,于是 SIGG 专注于做有内层镀膜的水壶。
传说 SIGG 原始公司的所有权,1999 年就已经被某投资集团接管。2003 年,SIGG 被美国 Riverside 收购。但之后不久,全球开始讨论 BPA 塑料制品的安全问题;而 SIGG 在这期间的表现……相当恶劣。SIGG 在 2008 年 8 月 之前生产的水壶,其内膜是包含 BPA 的;但他们对合作方,著名户外品牌 Patagonia,说他们的水壶内膜一直是 BPA-free 的。2009 年,Patagonia 的老板 Yvon Chouinard 手持 SIGG 水壶,在 Backpacker 杂志登广告阐述环保理念。但没过多久,SIGG 曾经含有 BPA 的事情就被揭露。Patagonia 愤怒地发表声明,终止和 SIGG 的一切合作,撤回杂志和合作卖出的 SIGG 水壶。
整个事件指名道姓的都是 SIGG,并没有谈到母公司是谁。2008 之后 SIGG 的镀膜也都是 BPA-free 了,但无疑这件事对市场的影响是巨大的。然而,具体严重到什么程度,我并没有特别直观的认识。日常见到的户外店和时尚家居店里,仍然还能见到 SIGG 的水壶在卖。但美国那边的控股方,生意大概是做不下去了吧?于是,2016 年,SIGG 被转卖给……浙江哈尔斯真空器皿,成交价 16.1m 瑞士法郎。
从此,SIGG 变成了国货……据说原始的铝瓶款还是在瑞士 Frauenfeld 制造(我对此表示怀疑);但 SIGG 官网上迅速多了一堆,有着明显义乌风格的国产不锈钢和玻璃保温杯,而铝瓶款也多出几款,瓶身凹嵌了橡胶隔热圈的迷之变形。不过浙江哈尔斯本身也在给 Stanley、Yeti 做代工,所以大概也是受后者的时尚路线影响……
关于车里用的燃气炉灶方案。因为只是简单的 van,而不是正式的房车,不存在内嵌的燃气系统,只是每天把各种气罐炉头搬来搬去。简要地说,每天使用最多的方案是:
从大号液化石油气罐(POL),先转成美式一磅罐卡口(UNEF 1″),再转接到户外圆罐炉头(Lindal B188)上。
这样的组合,可以随时把其中的一些环节,替换成其它款式的气罐和燃气用品。
户外常见的气罐接口,大概有这五种:
① POL,也就是最常见的大号「煤气罐」,准确地说,叫「液化石油气罐」。我这边日常可以买到的,有 3.7kg 和 8.5kg 两种容积。大的更划算,但我的床板下面只能放进小号的,换一瓶气大约 $20,Bunnings 和很多加油站都有换。
还有一种 LCC 27 接口,是 POL 的升级版。近年来政府渐渐把 POL 气罐,升级成更安全的 LCC 27 接口。这个是向下兼容的:原先用在 POL 上的管线,仍然可以拧进 LCC 27 的气罐;反之则不行,LCC 27 专用的管线,不能用在 POL 气罐上。所以,使用 POL 的管线,就不必在乎每次换到的气罐,是旧接口还是新接口。
② 3/8″ BSP-LH,另一种大号石油气罐的接口,通常只有专门的户外型房车才会使用。加油站很少见,更换气瓶也远不如 POL 方便。可以很方便地改成 POL,户外店有转接头卖($15)。
③ UNEF 1″ / BOM,北美常见的一磅重的绿气罐,北美的加油站和便利店到处都是,但澳洲和中国很少,只有专门户外店才有。
④ Lindal B188,又名 7/16 UNEF,户外背包露营时,最常见的扁圆气罐。虽然北美有很多炉头,都是 ③ 的 UNEF 接口,但毕竟 UNEF 接口过于笨重,自己背而不是车载露营的话,国际通用的炉头,更多的还是 ④ 的接口。
⑤ 常见的火锅店长气罐。虽然工艺远不如 ③ ④,但是更便宜也更好买,所以很多用 Lindal 圆罐炉头 ④ 的人,都会常备一个 ⑤→④ 的转换头($5)。(长罐到美式一磅罐 ⑤→③ 的转接头我从来没见过,大概因为美式罐太笨重了)
还有一些不常用的接口,譬如和 ④ 很像但是不带螺纹的气罐、以及一些笨重烧烤台用的 1/4” BSP……与本文无关,就不面面俱到地提及了。
一张图显示我日常的炉灶系统:
于是,日常使用最多的组合方案,包括:
日常煮食时,炉头和锅放在旁边的桌板,或者直接放在地上也可以。并不需要专门把气罐搬出来用。
其它车内需要用到燃气的装置,还有:
以及,必须的,一氧化碳监测仪,$25
ps,关于灌装。所有的一磅罐、户外圆罐、火锅长罐……厂家都是禁止用户自行灌注燃料反复使用的。但所有这些罐子,都存在着自行灌装的黑科技,以及相应的很便宜的转接头卖。其中美式一磅罐因为自带减压阀,比其它罐子更安全一些。个人感觉重复灌几次,还是没问题的。网上也不乏号称一个罐子反复用了一辈子的。但我还是不推荐读者贸然使用,请自行斟酌。如果只是偶尔用一下小罐子,多买几个一次性火锅气罐也就是了。
卖转接头的网店图。——但是连卖家的演示图,也是错误的。灌装时应该把大罐子倒置,让沉在下面的液态的石油气流进小罐子,而不仅仅是挥发的气态。
学微机原理的同学都是要求学汇编语言的,但是这种古老的语言并没有良好的移植性,用 Mac 的同学深受其害,往往都需要在 Windows 虚拟机下运行 Dos 模拟器完成,但是 macOS 下也有很棒的 DOS 模拟器,让我们可以跳过 Window 虚拟机这一环。
不要给我说 nasm 命令!!那个东西基本跟学校学习的汇编不兼容,劝发现这个命令的人老老实实用 DOS 模拟器吧。
Windows 下著名的 DOS 模拟器,华中科技大学自动化学生御用 DOS 模拟器,其官网已经多年没有更新了,所以对于最新的系统可能有一些兼容问题。
最新的版本是 2010 年推出的 0.74 版,之后就再也没有更新。细心的读者可能会发现,DOSBox 居然有 MAC OS X 版!各位,先别急着欢呼,我这里之所以用 MAC OS X 而没用 macOS 就是想提醒大家这个版本已经很老了,最新版的兼容性堪忧。
所以广大的 macOS 该怎么办呢?大家放心,既然我博文都写出来了,肯定有比装虚拟机更好的方法。
就是我们大名鼎鼎的 Boxer!虽然最新更新日期是 2016 年 2 月,快有一年没有更新了,但是相比于 DOSBox, 已经好太多。官网地址
软件本身自带几个 DOS 游戏,大家可以试着玩玩,但是我们今天的主题不是这个,而是用它进行汇编语言实验。
有了著名的 DOS 操作环境,下面我们需要搭建开发环境,毕竟 Boxer 本身是不包含编译汇编程序的。
这是我找的一份 DOS 环境下汇编语言开发包,提取码是 je38。至于从哪找的我已经忘了,反正好用无毒!
下载好后把里面的程序放到你的汇编语言开发环境中,即在同一个目录下。
打开 Boxer 后选择 Open a DOS prompt, 即进入的我们熟悉又和蔼的 DOS 操作环境。但是我们目前处于一个神奇的位置 — — Z 盘!Z 盘是在哪里呢?抱歉我也不知道,也不想知道。
我们目前要做的就是定位到我们的项目文件夹。方法很简单,也有多种,这里我介绍最方便的一种,其他的读者可以自己探索。
把你的项目文件夹直接拖动到 Boxer 窗口中,Boxer会把你拖动的文件夹当成 C 盘挂载。
挂载成功后,就是这样的!
输入 dir 我们可以浏览当前文件夹下都有哪些文件。
编译文件用 masm 命令,如:
masm example.asm
编译成功后会生成 .obj 文件,用命令 link 链接对应的文件生成可执行文件,如:
link example.obj
运行生成的 .exe 文件即可!
为了写长篇论文,整理各种散碎的构思和素材,尝试了一圈现有的写作工具。把体验的过程记一下。
先说结论。符合刚需,可供选择的,只有下面这几个。目前的考虑次序是:
参考过,因为不满足刚需被淘汰的:
有一些我知道但没有去试的,譬如 IA Writer。以及这些年似乎有很多,给网文作者开发的写作工具,就不去一个个试了。毕竟我只是要找个自己能用的,而不是做这方面的全面评测。
首先,我寻找的这个工具,是为了一个特定的写作项目,而不是日常泛泛的信息管理。所以,一些对于后者而言,很重要的功能,我是不需要考虑的。
六种工具的横向比较。空白的是我还没仔细看的。
