Smartphonen styrer vores hverdag. Den presser virkeligheden ind i sine platforme, så det, du ikke får i en app, ikke findes. Til gengæld får du adgang til et uendeligt univers af viden, kommunikationskanaler, tjenester og distraktioner. På bare få år har smartphonen gjort verden mindre og større, morsommere og kedeligere – mere nær og mere fjern. Livet er blevet friere og mere kontrolleret, mere socialt og mere asocialt, mens vi bliver både smartere og dummere. Det er en global, digital kulturrevolution, som savner sidestykke.I Appernes planet tager Thomas Hylland Eriksen os med på en rejse rundt i smartphonens verden. Hvis vi ikke skal blive slaver af mobilen, er det nødvendigt at forstå den for at kunne tage livet, kontrollen og ikke mindst tiden tilbage.

Startups og humanitære organisationer eksperimenterer verden over med ny, radikal teknologi i forsøget på at forbedre livsvilkårene for fattige og fordrevne. Håbet er, at nye digitale løsninger kan hjælpe folk til en bedre fremtid; at man med droner og biometriske registre kan levere mere effektiv nødhjælp, og at man med innovation kan understøtte den demokratiske udvikling og sikre menneskerettighederne.Men dataficerede tilgange til problemløsning er ikke garanti for fair eller objektiv behandling af hverken data eller mennesker. Når teknologien udvikles tusindvis af kilometer fra der, hvor den skal hjælpe mennesker i nød, har den ofte form af lappeløsninger, ligesom der sker læk med uoverskuelige konsekvenser for de mest udsatte.Vi har brug for en mere lige og kollektiv teknologiudvikling, der vender eksisterende hierarkier på hovedet og tænker i bredere forandring. Kun sådan kan vi sikre, at interventioner båret af ny teknologi er så relevante, effektive og bæredygtige som muligt.Adam Moe Fejerskov (f. 1987) er senior­forsker ved DIIS, hvor han beskæftiger sig med globale uligheders konsekvenser rundt om i verden, og hvordan uligheder formes af forhold som ny radikal teknologi.

Den teknologiske udvikling har længe handlet om at overvinde, udnytte og frigøre os fra naturen. Fremtiden handler om at forstå biologien og økosystemerne og om en økonomi, der fungerer i samarbejde og sammenhæng med naturen. For ét er sikkert: Vi kan ikke fortsætte, som vi plejer. Denne bog argumenterer for, at vi står overfor tre store omstillinger, som sker samtidig og indenfor de næste par årtier. Alle tre skal lykkes:- Vores forhold til naturen og de økosystemer, vi er del af, skal redefineres – og det skal gå stærkt.- Vi er på vej ud af industrisamfundet og ind i en ny tids logik, så måden vi organiserer arbejdet og deler goderne på trænger til en opdatering.- I takt med at teknologien bliver mere intelligent, liv-agtig og kompetent, skal vi gentænke menneskers og maskiners roller i forhold til hinanden for at bevare styringen. Omstilling til fremtiden ser på, hvad vi kan gøre for at sikre, at de enorme kræfter, der er på spil i de kommende års omstilling, vil bringe os fremgang frem for katastrofe. Bogen viser en fremtid, der er grundlæggende forandret – men til det bedre. Bogen er blandt andet baseret på interviews med en lang række af verdens førende forskere, økonomer og ledere i erhvervslivet og analyser for Ugebrevet Mandag Morgen.

Barry C. Lynn, en af Amerikas mest fremtrædende samtidstænkere, giver os en tydelig illustration af, hvor grelt det står til med friheden, efter den er blevet overtaget af Amerikas nye giga-monopoler.Amerikanere tørster efter frihed, og diskussioner om hvor meget frihed der skal til for at købe et våben, få en abort, gifte sig af kærlighed eller skifte køn fylder meget i medierne. Kampen for frisættelse fra statens reguleringer og oprør mod regeltyranni er et ideal for mange.Alligevel begynder amerikanerne først nu at indse det, som måske er den største trussel mod frihed i flere århundreder: Den ekstreme og hurtigvoksende koncentration af økonomisk magt. Store monopoler kontrollerer i dag næsten alle hjørner af den amerikanske økonomi. Konsekvensen er ikke kun lavere lønninger og højere priser, hvilket er et naturligt resultat af magtens og velstandens koncentration på meget få hænder. Også arbejdskraftens mobilitet, muligheden for at starte små virksomheder og se dem blomstre er udfordret. Kombineret med de store onlinemonopoler som Google og Amazons fremgang, skabes der grobund for en verden, hvor få, store konglomerater dels forringer den almindelige borgers generelle livskvalitet gennem dårligere lønninger og vilkår på arbejdspladsen, dels dikterer hvordan borgerne tænker, hvem de kommer i forbindelse med, og hvilket billede af omverdenen de præsenteres for. Hvordan stemmer det overens med USA’s fremherskende frihedsideal? Det undersøger Barry C. Lynn i Fri os fra alle herskere.

Inden for de senere år er skolen blevet gradvis meredigitaliseret. Digitaliseringen inviterer til nye læreprocesser, men udfordrerogså didaktik og dannelsessyn.

PC- og onlinesikkerhed er i stigende grad blevet vigtigt for pc-brugere over hele verden. Der er en lang række trusler, der kan ramme dig, når du er på Internettet. Du har måske hørt om en række former for skadelige programmer, der under ét kaldes for malware, og som kan ramme den intetanende pc- og smartphonebruger. Der kan være tale om: Virus – programmer, der smitter og inficerer ens egen og andre pc’er på netværket. Trojanske heste – programmer, som har en skadelig ladning af malware med sig. Spyware – programmer, der udspionerer din gøren og laden på pc’en, og som f.eks. sender dine indtastede kreditkortoplysninger videre til en bagmand. Keyloggere – programmer der registrerer alt, hvad du taster på tastaturet, og sender det til en bagmand. Zombier – din pc kan blive overtaget af en bagmand og skjult indlemmet i et netværk (botnet) af andre zombie-computere, som sammen angriber hjemmesider eller sender store mængder spam ud i verden. Adware – programmer, der viser reklamer på din pc og på hjemmesider, og som er meget irriterende. Ransomware – du kan blive afkrævet en løsesum for at slippe din pc fri for malware, der krypterer dine filer, så du ikke kan læse dem igen. Du lærer om: Identitetstyveri – pas på ikke at få stjålet dine personlige oplysninger, som kriminelle så kan misbruge. Fupbutikker – lær at spotte falske netbutikker, som sælger kopivarer under dække af at være ægte eller sælger dine kreditkortoplysninger. Digitalt selvforsvar – hvordan sikrer du din anonymitet på nettet? Lær om browseranonymitet og andre værktøjer såsom TOR-netværket, der øger din grad af anonymitet på både pc og smartphone. Dine børns onlinesikkerhed – Windows stiller en række værktøjer til rådighed for forældres styring af deres børns brug af pc’en. Læs også hvordan du sikrer dine børns smartphones og tablets. Adgangskoder – hvordan gør man dem sikre? Hvor mange skal man have? Lær også om farerne ved uopfordret tilsendte e-mails: At der kan følge malware med i en vedhæftet fil (bilag) i en e-mail. At du har vundet millioner i et lotteri, uden at du har deltaget i det. At en person har arvet en millionsum, men har brug for en udlænding (dig) til at overføre pengene til sig – mod betaling af en procentdel af arven. At blive mellemmand (muldyr) med en bankkonto til at modtage penge og sende dem videre for et udenlandsk firma – mod at beholde nogle få procent af beløbet. At dit NemID er midlertidigt suspenderet – indtil du oplyser dit NemID-log-ind og uploader et billede af dit nøglekort. Læs om farerne for og hvordan du sikrer dit NemID og netbank. At din PayPal-konto er blevet kompromitteret, og at du derfor skal bekræfte dit log-ind. At du skal sende din Verified-by-Visa-SMS-kode videre per SMS til en bagmand. At en person, du har fået kontakt med via en dating-hjemmeside, akut har brug for mange penge. Heldigvis kan man med oplysning og uddannelse og de rette sikkerhedsprogrammer gardere sig mod disse farer og færdes ret sikkert på nettet alligevel. Denne bog med mange illustrationer beskriver disse farer indgående og oplyser om, hvilke faresignaler du skal være agtpågivende overfor. Der er sammenligninger af antivirusprogrammer med firewall, så du kan se hvilke programmer, der er gode lige nu. Hvis du skulle være blevet ramt af malware, er der også beskrevet nogle fremgangsmåder, hvormed du kan fjerne den igen. Desuden lærer du om sikkerhedskopiering, så du ikke behøver at miste dine filer, hvis du rammes af ransomware.

Excel til andet end forretningsprocesser og andre seriøse - og mere almindelige - anvendelser Om at gøre regnearket til et værktøj der kan meget mere Om nye ideer, sjove indfald og at gøre det umulige muligt I denne omgang gælder det alt andet end noget seriøst, for ja, Excel kan sagtens benyttes til en masse underholdning og ikke kun anvendes forretningsmæssigt. Man skal nok være lidt ekstra vild med - eller skør med - Excel, kodning og at fordybe sig i denne tekniske og måske nok lidt smånørdede verden. Men når det er på plads, er der masser af sjove muligheder lige ved hånden. Formålet er stadig - ligesom de tidligere hæfter - at tænke alternativt, kigge udover hvad der i dag er muligt eller tænkeligt, og overgå det.

Mode- og tekstilindustrien står over for en række forandringer, som følge af klimakrisen. Vi skal sætte ind over for den overproduktion af tøj, der i dag finder sted, og tekstiler skal i højere grad genanvendes. Udviklingen kommer ikke til at ske over en nat. Men det positive er, at vi med nye digitale teknologier som AI, Blockchain, Virtual-, Augmented-, og Mixed Reality, samt 3D konstruktionssoftware til tøj, har fået en værktøjskasse, som i meget høj grad kan hjælpe både ledelse og medarbejdere til at løfte denne opgave. Med 3D software til tøj kan du f.eks. visualisere og sælge kollektioner inden de fysisk er fremstillet, og du kan reducere opsyning af prøvemodeller og fittings til et minimum. Vælger du også at inddrage AI i din designproces får du pludselig et redskab til hurtigt at skabe nye tekstilprints, eller billedmateriale til markedsføringen af din kollektion. I seks kapitler præsenteres en lang række eksempler på, hvordan du kan anvende Metaversets nye teknologier i dit daglige arbejde som designer eller leder. Bogen retter sig ikke kun mod modeindustrien, men kan også indtænkes i andre former for design-, markedsførings-, kommunikations- og produktudviklingsopgaver.

I "Maskinerne kommer indefra" forklarer Anders Søgaard, hvordan kunstig intelligens lærer at se, tale og tænke – men han spørger også, hvorvidt kunstig intelligens lærer at se, tale og tænke på samme måde som os? Er der noget, mennesker kan, som kunstig intelligens aldrig vil blive i stand til? Og i hvilket omfang vil kunstig intelligens ændre, hvem vi er? Kunstig intelligens er blevet mere og mere intelligent, men er vi også langsomt ved at blive mere og mere kunstige?Om forfatteren:Anders Søgaard (f. 1981) er forfatter og professor på Datalogisk Institut, Københavns Universitet, og er en af landets førende eksperter i maskinlæring og kunstig intelligens.

Machine Learning (ML)-based Artificial Intelligence (AI) algorithms have the capability to learn from known examples, creating various abstract representations and models. When applied to unfamiliar examples, these algorithms can perform a range of tasks, including classification, regression, and forecasting, to name a few.Frequently, these highly effective ML representations are challenging to comprehend, especially in the case of Deep Learning models, which may involve millions of parameters. However, in many applications, it is crucial for stakeholders to grasp the reasoning behind the system's decisions to utilize them more effectively. This necessity has prompted extensive research efforts aimed at enhancing the transparency and interpretability of ML algorithms, forming the field of explainable Artificial Intelligence (XAI).The objectives of XAI encompass: introducing transparency to ML models by offering comprehensive insights into the rationale behind specific decisions; designing ML models that are both more interpretable and transparent, while maintaining high levels of performance;, and establishing methods for assessing the overall interpretability and transparency of models, quantifying their effectiveness for various stakeholders.This Special Issue gathers contributions on recent advancements and techniques within the domain of XAI.
